Please help! Find the measure of angle 1in the rhombus

Answer: The board is 54 inches wide

The width of a whiteboard, in inches, is 54.

Multiplication is a type of mathematical operation. The repetition of the same expression types is another aspect of the practice.

For instance, the expression 2 x 3 indicates that 3 has been multiplied by two.

We know that the width of the whiteboard is 4.5 feet.

However, if we need to express this width in inches, we have to convert feet to inches, as the two units are not directly comparable.

There are 12 inches in a foot.

Therefore, to convert a value in feet to inches, we can simply multiply the value by 12. In other words, 1 foot is equal to 12 inches.

So, to convert the width of the whiteboard from feet to inches, we can simply multiply the width (4.5 feet) by the conversion factor of 12 inches/foot as follows:

4.5 feet × 12 inches/foot = 54 inches

Therefore, the whiteboard is 54 inches wide.

The two most commonly used measures of variability are variance and standard deviation.

1. Variance: Variance measures how spread out a set of data points is from the mean. It calculates the average of the squared differences between each data point and the mean. The formula for variance is sum of squared differences divided by the number of data points.

Example: Let's say we have a set of data points: 2, 4, 6, 8, and 10. The mean of these data points is 6. The differences between each data point and the mean are: -4, -2, 0, 2, and 4. Squaring these differences gives us: 16, 4, 0, 4, and 16. The sum of these squared differences is 40. Dividing this sum by the number of data points (5) gives us a variance of 8.

2. Standard Deviation: Standard deviation is the square root of variance. It measures the average distance between each data point and the mean. Standard deviation is often preferred over variance because it is in the same unit as the data points, making it easier to interpret.

Example: Using the same set of data points as above, the variance is 8. Taking the square root of 8 gives us a standard deviation of approximately 2.83.

In summary, variance measures how spread out the data points are from the mean, while standard deviation gives us a more intuitive understanding of the variability by providing a measure in the same unit as the data points. These measures help us understand how the data is distributed and how much it deviates from the average.

The sum of the first 50 terms of the sequence is 2255. The nth term of the quadratic sequence is given by \(t_n = 2n^2 + 6n + 4\). The 23rd term of the sequence is 1354.

The first 50 terms of the sequence can be split into two alternating sequences: a geometric sequence with first term 1/2 and common ratio 1/2, and an arithmetic sequence with first term 4 and common difference 3. The sum of a geometric series is given by \(a_1(1-r^n)/(1-r)\), where \(a_1\) is the first term, r is the common ratio, and n is the number of terms. The sum of an arithmetic series is given by \(n/2(a_1+a_n)\), where n is the number of terms, \(a_1\)is the first term, and \(a_n\) is the nth term.

The nth term of the quadratic sequence is given by \(t_n = 2n^2 + 6n + 4\). To find the 23rd term, we can simply substitute n=23 into the equation. This gives us \(t_{23} = 2(23)^2 + 6(23) + 4 = 1354.\)

Answer:

To calculate the current population of the town after 2 years, we first need to find the total number of months:

Total number of months = 2 years x 12 months/year = 24 months

Next, we can use the formula for compound interest to calculate the population after 24 months:

P = A(1 + r/100)^n

where:

P = final population

A = initial population (3000)

r = monthly growth rate (3.274%)

n = total number of months (24)

Plugging in the values, we get:

P = 3000(1 + 3.274/100)^24

P ≈ 4144

Therefore, the current population of the town is approximately 4144 people.

To solve the given system of equations using the substitution method, we need to solve one equation for one variable and then substitute that expression into the other equation for that same variable. Let's solve the second equation for y.

-x + y = 4

y = x + 4

Now we can substitute this expression for y into the first equation and solve for x.

-2x + 2(x + 4) = 7

-2x + 2x + 8 = 7

8 = 7

The equation 8 = 7 is not true, which means the system of equations has no solution. We can see this visually by graphing the two lines. They are parallel and will never intersect, which means there is no point that satisfies both equations.

Therefore, the solution to the system of equations is "No solution."

Answer:

The length of the missing leg is six

Step-by-step explanation:

Assuming that this is a right triangle, you can use the Pythagoras theorem

12^2+x^2=sqrt180^2

144+x^2=180

x^2=36

x=6

Therefore, the length of the missing leg is six.

Answer:

Taking the above as a right angled triangle...

Pythagoras' rule can be applied to get the Missing side.

It goes...

Hyp² = Opp² + Adj²

Which translates to Hypotenuse, Opposite and Adjacent respectively.

Hyp = √180

Opp= 12

So we're missing Adj

Making adj the subject.

Adj = √ Hyp² – Opp²

= √[(√180)² – (12)²

= √ [ 180 – 144]

= √36

Adj = 6ft.

Answer:

y = 8x+6

Step-by-step explanation:

First find the slope since it is a linear function

m = (y2-y1)/(x2-x1)

    = (18-2)/(1 1/2 -  -1/2)

    =16 /  (1 1/2 +1/2)

    = 16/2

  = 8

The linear function is in the form

y = mx+b where m is the slope

y = 8x+b

Substitute the other point into the equation to determine b

10 = 8(1/2) +b

10 = 4+b

10-4 = b

6 = b

y = 8x+6

x=-4, y=-1

Step-by-step explanation:

Given the following system of equations, solve the system using elimination.

\(\left \{ {{-2x-y=9} \atop {2x-9y=1}} \right.\)

(1) - Add the equations together

\(\left\begin{array}{ccc}&-2x-y=9\\+&2x-9y=1\end{array}\right\\\\\Longrightarrow -10y=10\\\\\therefore \boxed{y=-1}\)

Notice how the x term was eliminated, hence the name for this method is "elimination."

(2) - Take the value we just found for y and plug it into either of the two equations and solve for x

\(2x-9y=1\\\\\Longrightarrow 2x-9(-1)=1\\\\\Longrightarrow 2x+9=1\\\\\Longrightarrow 2x=-8\\\\\therefore \boxed{x=-4}\)

(3) - Thus, the system is solved. When x=-4, y=-1.

Answer:

Therefore, the book value of the equipment at the end of year four (including year four) is $2,880.

Step-by-step explanation:

To calculate the book value of the equipment at the end of year four using the MACRS method with GDS recovery period of five years, we can use the following steps in Excel:

1. Open a new Excel spreadsheet and create the following headers in row 1: Year, Cost, Depreciation Rate, Annual Depreciation, Cumulative Depreciation, and Book Value.

2. Fill in the Year column with the years 1 through 6 (since the truck has a life of six years).

3. Enter the cost of the truck, $12,000, in cell B2.

4. Use the following formula in cell C2 to calculate the depreciation rate for each year:

=MACRS.VDB(B2, 5, 5, 1, C1)

This formula uses the MACRS.VDB function to calculate the depreciation rate for each year based on the cost of the truck (B2), the GDS recovery period of five years, the useful life of six years, the salvage value of $2,000, and the year (C1).

5. Copy the formula in cell C2 and paste it into cells C3 through C7 to calculate the depreciation rate for each year.

6. Use the following formula in cell D2 to calculate the annual depreciation for each year:

=B2*C2

This formula multiplies the cost of the truck (B2) by the depreciation rate for each year (C2) to get the annual depreciation.

7. Copy the formula in cell D2 and paste it into cells D3 through D7 to calculate the annual depreciation for each year.

8. Use the following formula in cell E2 to calculate the cumulative depreciation for each year:

=SUM(D$2:D2)

This formula adds up the annual depreciation for each year from D2 to the current row to get the cumulative depreciation.

9. Copy the formula in cell E2 and paste it into cells E3 through E7 to calculate the cumulative depreciation for each year.

10. Use the following formula in cell F2 to calculate the book value of the equipment for each year:

=B2-E2

This formula subtracts the cumulative depreciation for each year (E2) from the cost of the truck (B2) to get the book value.

11. Copy the formula in cell F2 and paste it into cells F3 through F7 to calculate the book value for each year.

12. The book value of the equipment at the end of year four (including year four) is the value in cell F5, which should be $2,880.

Let's assume the speed of the plane in still air is represented by 'p' (in mph).

When the plane is flying with the wind, its effective speed increases by the speed of the wind. So the speed of the plane with the wind is 'p + 10' (in mph).

When the plane is flying against the wind, its effective speed decreases by the speed of the wind. So the speed of the plane against the wind is 'p - 10' (in mph).

The time taken to travel a certain distance is given by the formula: Time = Distance / Speed.

Given that the length of time is the same for both situations, we can set up the following equation:

495 / (p + 10) = 440 / (p - 10)

We can cross-multiply to solve for 'p':

495(p - 10) = 440(p + 10)

495p - 4950 = 440p + 4400

495p - 440p = 4400 + 4950

55p = 9350

p = 9350 / 55

p ≈ 170

Therefore, the speed of the plane in still air is approximately 170 mph.

Step-by-step explanation:

1 Large Pizza = 12.99

4 Large Pizza = 4*12.99 = 51.96

The question is not exactly clear. Do you add on the delivery charge now of do you do it at the end? If you do it now, you are saying it is taxable. Coach Yip is just an individual, not a business. The pizza parlor will treat it as an expense. I would say you do it at the end.

Total Including tax is

51.96* ( 1 + 7.5/100)

Total = 55.86

Now add on the delivery cost

Total Cost = 55.86 + 2.50

Total Cost = 58.36

Comment: If you get this answer wrong using B, then the answer A because the 2.50 is added on before the tax is calculated.

Cost before taxes = 54.46

Total Cost with taxes = 54.46 * 1.075 = 58.54.

Step-by-step explanation:

Kayden's math teacher said that each question answered correctly on a test would be worth 7 points. Answer the questions below regarding the relationship between the number of questions correct and the score on the test.

Since 00 questions correct gets you 00 points on the test, the function will have a yy-intercept of 0.0.

The rate at which points are earned is 7 points per question, so the slope of the function should be 7.7.

\text{Function Rule:}

Function Rule:

V(x)=7x

V(x)=7x

Plug x=11 Into Rule:

V(11)=7(11)=77

Correct Answer:

The independent variable, x, represents the number of questions correct, and the dependent variable is the score on the test, because the score on the test depends on the number of questions correct.

A function relating these variables is V(x) =V(x)= 7x7x.

So V(11) =V(11)= 7777, meaning 1111 questions correct will earn 7777 points on the test

According to given information, the integrals are found below.

In order to evaluate the integral ∫(x + 1)^(-2/3) dx, with the given substitutions, we will perform each step one by one.

Substitution (a):

If we substitute u = 1/(x + 1), then du/dx = -1/(x + 1)^2, which implies -du = dx/(x + 1)^2.

Now, using the above relation and substituting the value of u in the given integral, we get∫(x + 1)^(-2/3) dx = -3∫u^(-2/3) du= 3u^(-2/3) + C, where C is the constant of integration.

Substituting the value of u in the above relation, we get \(\int(x + 1)^{(-2/3)} dx = 3(x + 1)^{(2/3)} + C1\), where C1 is a new constant of integration.

Substitution (b):

If we substitute u = ((x - 1)/(x + 1))^k, where k is any of the given values, then we have

\(u^3 = (x - 1)^k/(x + 1)^k.\)

So,\(du/dx = [(k(x + 1)(x - 1)^(k-1) - k(x - 1)(x + 1)^(k-1))/((x + 1)^k)^2]\)

Now, we can substitute the value of u and du/dx in the given integral and get the required value of the integral.

Substitution (c):

If we substitute u = tan x, then du/dx = sec^2 x, which implies du = sec^2 x dx.

Now, substituting the value of u in the given integral and using the above relation, we get

\(\int(x + 1)^{(-2/3)} dx = \int(1 + tan x)^{(-2/3)} sec^2 x dx\\= \int (1 + tan x)^{(-2/3)} du\), where u = 1 + tan x.

Substituting the value of u and using the relation \((a + b)^n = \sum(nCr)(a^{(n-r)})(b^r)\), where nCr is the binomial coefficient, we get∫(x + 1)^(-2/3) dx = -3(1 + tan x)^(1/3) + C2, where C2 is a new constant of integration.

Substitution (d):

If we substitute u = tan^2 x, then du/dx = 2 tan x sec^2 x, which implies dx = du/(2 tan x sec^2 x) = du/(2u + 1)

Now, substituting the value of u and dx in the given integral, we get

\(\int(x + 1)^{(-2/3) }dx = \int (u + 1)^{(-2/3)} (du/(2u + 1))\\= (3/2)\int (u + 1)^{-2/3} d(u + 1)/(2u + 1)\\= (3/2) (2u + 1)^{(-1/3) }+ C3\),

where C3 is a new constant of integration.

Substituting the value of u in the above relation, we get

\(\int (x + 1)^{(-2/3) }dx = (3/2) ((x + 1)/2 + 1)^{(-1/3) }+ C3\\= (3/2) ((x + 3)/2)^{(1/3)} + C3.\)

Substitution (e):

If we substitute \(u = tan^{(-1) }[(x - 1)/2]\), then tan u = (x - 1)/2, which implies 2 sec^2 u du = dx

Now, substituting the value of u and dx in the given integral, we get

\(\int (x + 1)^{(-2/3)} dx = \int (1 + 2 tan^2 u)^{(-2/3)} (2 sec^2 u) du\\=\int (1 + 2 (sec^2 u - 1))^{(-2/3)} (2 sec^2 u) du\\= 2∫(sec^2 u)^{(-2/3)} du\\= 2∫cos^{(-4/3)} u du\\= (2/3) sin u cos^{(-1/3) }u + C4\),

where C4 is a new constant of integration.

Substituting the value of u in the above relation, we get

\(\int (x + 1)^{(-2/3) }dx = (2/3) (x - 1) cos^{(-1/3) }[(x - 1)/2] + C4\).

Substitution (f):

If we substitute u = cos x, then du/dx = -sin x, which implies dx = -du/sin x.

Now, substituting the value of u and dx in the given integral, we get

\(\int (x + 1)^{(-2/3) }dx = -\int (1 - cos^2 x)^{(-2/3)} (-du/sin x)\\= \int (1 - u^2)^{(-2/3)} du\\= (-1/3) (1 - u^2)^{(-1/3)} + C5\),

where C5 is a new constant of integration.

Substituting the value of u in the above relation, we get

\(\int (x + 1)^{(-2/3) }dx = (-1/3) [(x - 1)/(x + 1)]^{(-1/3)} + C5\\= (-1/3) (x + 1)^{(-1/3) }(x - 1)^{(-1/3)} + C5\).

Substitution (g):

If we substitute u = cosh x, then du/dx = sinh x, which implies dx = du/sinh x.

Now, substituting the value of u and dx in the given integral, we get

\(\int (x + 1)^{(-2/3)} dx = \int (cosh^2 x + 1)^{(-2/3)} (du/sinh x)\\=\int (sinh^2 x + 1)^{(-2/3) }(du/sinh x)\\= (-2/3) (sinh^2 x + 1)^{(-1/3)} + C6\),

where C6 is a new constant of integration.

Substituting the value of u in the above relation, we get

So, integral 1 / (x + 1)2/3 = ∫-3u du = - 3 * u + C

Where C is a constant of integration.

Substitution 2:

u = (x - 1) / (x + 1)du = 2 dx / (x + 1)2

Therefore, x = 2 and -2. Plug both of these into an equation to solve for the 'y' value:

f(x) = -2(2) + 7

f(x) = -4 + 7

f(x) = 3

The objective function represents the quantity to be maximized or minimized, such as profit, cost, time, or resource utilization. The constraints define the limitations or restrictions on the decision variables.

Decision Variables:

Let X be the number of Yummy patties produced per month.

Let Y be the number of Wholesome patties produced per month.

Objective Function:

Minimize the total cost of producing and storing Yummy and Wholesome sandwich patties.

Total Cost = (Production Cost per patty * Number of Yummy patties) + (Production Cost per patty * Number of Wholesome patties) + (Storage Cost per patty * Number of Yummy patties) + (Storage Cost per patty * Number of Wholesome patties)

Constraints:

Production capacity constraint: X + Y <= 12,000,000 (the total number of patties produced per month should not exceed 12 million).

Demand constraints: X >= demand for Yummy patties per month

Y >= demand for Wholesome patties per month

Fat content constraint: (20X + 8Y) / (X + Y) <= 13 (average fat content should not exceed 13 grams per patty)

To solve this linear programming problem and optimize the total cost, you can use Solver in software like Microsoft Excel. Here are the steps to set up and solve the problem using Solver:

Set up the spreadsheet:

Create a table with columns for variables (X and Y), objective functions, and constraints.

Enter the appropriate formulas for the objective function and constraints based on the given information.

Define the objective cell as the total cost and set it to minimize.

Set up the Solver:

Open Solver in Excel (usually found under the Data or Analysis tab).

Set the objective cell as the target to minimize.

Define the decision variables and their limits (X and Y >= 0).

Add the constraints based on the given conditions.

Set the Solver options as needed (non-integer solutions are allowed).

Run the Solver:

Click the Solve button to find the optimal solution.

Solver will adjust the values of X and Y to minimize the total cost while satisfying the constraints.

Review the results:

Once Solver completes, review the solution provided.

The optimized values of X and Y will represent the number of Yummy and Wholesome patties produced per month.

The total cost of production and storage will be minimized according to the objective function.

By following these steps and using Solver, you can find the optimal solution for minimizing the total cost of producing and storing Yummy and Wholesome sandwich patties while satisfying the given constraints.

Answer:

1140 households

Step-by-step explanation:

The results of a computer survey of 80 households in Westville are shown in the table.

So from the table we can see that 6 households have 3 numbers of computers.

So the probability is \($\frac{6}{80}$\)

Therefore, the probability of number of houses from a total of 15,200 houses to have exactly three computers is = \($\frac{6}{80} \times 15200$\)

                                                          = 1140 houses

The maximum profit is approximately $173,023.32. First, we need to find the revenue function, which is given by:

R(x) = xp(x)

where p(x) is the price function. We are given that:

p(x) = 2096 - x^2

Therefore, the revenue function is:

R(x) = x(2096 - x^2) = 2096x - x^3

Next, we need to find the cost function, which is given by:

C(x) = 900 + 20x + x^2

Finally, the profit function is given by:

P(x) = R(x) - C(x) = (2096x - x^3) - (900 + 20x + x^2) = -x^3 + 2076x - 900 - x^2

To find the maximum profit, we need to find the critical points of P(x), which occur when P'(x) = 0. We have:

P'(x) = -3x^2 + 2076 - 2x

Setting P'(x) = 0 and solving for x, we get:

-3x^2 + 2076 - 2x = 0

3x^2 - 2x + 2076 = 0

Using the quadratic formula, we get:

x = [-(-2) ± sqrt((-2)^2 - 4(3)(2076))]/(2(3)) ≈ 19.47, -35.94

Since production is limited to 1000 units, we can only consider the positive root, x ≈ 19.47. Therefore, the quantity that will give the maximum profit is 1947 hundred units.

To find the maximum profit, we evaluate P(x) at x = 19.47:

P(19.47) = -(19.47)^3 + 2076(19.47) - 900 - (19.47)^2 ≈ $173,023.32

Therefore, the maximum profit is approximately $173,023.32.

Note: It is important to check that this is indeed a maximum by verifying that the second derivative of P(x) is negative at x = 19.47. This is left as an exercise for the reader.

The correlation coefficient is 0.9541. This can be determined from the information provided in the ANOVA table, specifically the regression sum of squares (SSR) and the total sum of squares (SST).

The correlation coefficient, also known as the Pearson correlation coefficient, is a measure of the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where values closer to -1 or 1 indicate a stronger relationship, and values closer to 0 indicate a weaker relationship.

To calculate the correlation coefficient, we can use the formula:

r = sqrt(SSR/SST)

From the ANOVA table provided, we can see that SSR = 12,323.64 and SST = 13,538.4. Plugging these values into the formula gives:

r = sqrt(12,323.64/13,538.4) = 0.9541

Therefore, the correlation coefficient for this model is 0.9541, indicating a strong positive linear relationship between the independent variable and the dependent variable

By using factoring by grouping or synthetic division, we find that \(x = -2\) is a real solution.

Checking for Rational Roots

Using the rational root theorem, the possible rational roots of the polynomial are given by the factors of the constant term (24) divided by the factors of the leading coefficient (-4).

The possible rational roots are ±1, ±2, ±3, ±4, ±6, ±8, ±12, ±24.

By substituting these values into \(f(x)\), we find that \(f(-2) = 0\). Hence, \(x + 2\) is a factor of \(f(x)\).

Dividing \(f(x)\) by \(x + 2\) using long division or synthetic division, we get:

Now, we have reduced the problem to factoring \(-4x³ + 18x² - 16x + 12\).

Attempt 2: Factoring by Grouping

Rearranging the terms, we have:

Factoring out common factors, we obtain:

Now, we have \(2x^2(-2x + 9) + 4(4x - 3)\). We can further factor this as:

Therefore, the fully factored form of \(f(x) = -4x⁴  + 26x³  - 50x² + 16x + 24\) is \(f(x) = (x + 2)(2x² + 4)(-2x + 9)\).

Solutions to the polynomial equations:

Using polynomial division or synthetic division, we can find the quadratic equation \((x + 2)(x² + 2x - 3)\). Factoring the quadratic equation, we get \(x² + 2x - 3 = (x +

Answer:

The expression √x+5+√1-x is defined for all values of x such that the value under the square root sign is non-negative. We can find the values of x that satisfy this condition by considering each of the square roots separately.

For the first square root, the value under the square root must be non-negative, so we have the following inequality:

x + 5 ≥ 0

x ≥ -5

For the second square root, the value under the square root must be non-negative, so we have the following inequality:

1 - x ≥ 0

x ≤ 1

Therefore, the expression is defined for all values of x that satisfy both of these inequalities. This means that the expression is defined for values of x in the range -5 ≤ x ≤ 1. The correct answer is therefore option D.
