What is the image of the point (5,-4) after a rotation of 90° counterclockwise about the origin?​

Answer:

6 1/2 (mixed) or 25/4 (improper)

Step-by-step explanation:

Firstly, I made the mixed number an improper fraction; 5/4

Then I did the equation;

5/1 x 5/4 = 25/4

25/4 is 6.25 when divided, then made it a fraction; 6 1/4

The total surface area of the pyramid is  335 square centimeters

The formula for determining the total surface area of a pyramid is expressed as;

TSI = 1/2(PI) + B

Given that;

Now, let's determine the base perimeter

Perimeter = 2( l + w)

Substitute the values

Perimeter = 2 ( 8 + 12)

Perimeter = 40 centimeters

The base area is given as;

Base area =  8(12)

Base area = 96 square centimeters

Substitute the values, we have;

Total surface area = 1/ 2 (40)(12) + 96

Total surface area = 240 + 96

Total surface area = 335 square centimeters

Hence, the value is 335 square centimeters

Answer:

x = 5 and y = 7

Step-by-step explanation:

Given that,

PT = x+2, TR=y, QT=2x, TS=y+3

We need to find the value of x and y.

The diagonal of a parallelogram bisect each other. It means,

PT = TR and QT = TS

ATQ,

y = x+2 ...(1)

and

y+3 = 2x ....(2)

Subtracting equation (1) and (2).

y-(y+3) = x+2-2x

y-y-3 = 2-x

-3 = 2-x

x = 2+3

x = 5

Put the value of x in equation (1).

y = 5 + 2

y = 7

Hence, the values of x and y are x = 5 and y = 7.

Find a point-slope form for the line that satisfies the stated conditions. Slope , passing through (-5,4)

I really need this question answered

By:

I don't see a value for the slope. We need that to set the equation, otherwise I can write an unlimited number of equations that pass through (-5,4).

I'll assume a slope so that you can see how the procedure would work. I like 6, so we'll assume a slope of 6.

The equation for a straight line has the form y = mx + b, where m is the slope and y is the y-intercept, the value of y when x = 0. We want a line that has slope 6, so:

y = 6x + b

We need to find b, so substitute the point (-5,4) that we know is on the line:

4 = 6*(-5) + b and solve for b

4 = -30 + b

b = 34

The line is y = 6x + 34

Answer:

B) 32 degrees

Step-by-step explanation:

Firstly, identify that the sum of the interior angles of a triangle always equals 180 degrees. By looking at the side of angle A and C, we notice they are equal, which means the measure of the angles are equal. So 74 degrees plus 74 degrees equals 148 degrees. 180 degrees minus 148 degrees equals 32, which is the measure of angle B. Let me know if you have any further questions.

The required orders are Kara served 12.5 orders, Harry served 22.5 orders, and Erin served 50 orders.

An equation that holds true for one or more values of the variable but holds false for other values of the variable is known as a conditional equation. In Hannah's example, the equation holds true for the value of x equal to 10, but not for other values, such as 1. The equation is a conditional equation as a result.

Let we consider the number of orders Kara served as x.

Then, Harry served x + 10 orders and Erin served 4x orders.

The total number of orders they served is x + x + 10 + 4x = 86 orders.

So, 6x + 10 = 86

6x = 76

x = 12.5

Kara served 12.5 orders, Harry served 22.5 orders, and Erin served 50 orders.

Answer:

Step-by-step explanation:

Let the orders served by Kira be k.

Orders served by Henry= 10 less than Kira

                                       = k-10

Orders served by Erin= 4 times of Kira

                                   = 4k

Total orders served= 86

     Kira+Henry+Erin= 86

               k+k-10+4k= 86

                       6k-10= 86

                            6k= 86+10

                            6k= 96

                              k= 96/6

                              k= 16

Kira= k= 16

Henry= k-10= 16-10= 6

Erin= 4k= 4x16= 64

∴ Kira served 16 orders, Henry served 6 orders & Erin served 64 orders

The price that Maura sell each scarf would be =$33. Maura sells each scarf for $33. That is option A.

To calculate the amount of money that Maura spends on each scarf the following is carried out.

The amount of money that she spends on the scarf material = $5.50

The percentage selling price of each scarf = 600% of $5.50

That is ;

= 600/100 × 5.50/1

= 3300/100

= $33.

Therefore, each price that is sold by Maura would probably cost a total of $33.

The required eigenvalue and its associated eigenvector are λ = 7 and [3, 2] respectively.

To find the associated eigenvectors for a given eigenvalue, we need to solve the equation Av = λv where A is a square matrix, v is the eigenvector, and λ is the eigenvalue given.

suppose the given matrix A = [1 2; 2 1] and eigenvalue λ = 7.

Substituting these values in the above equation, we get Av = λv as:

[1 2; 2 1][x; y] = 7[x; y]

Simplifying the above equation, we get the following system of equations:

x + 2y = 7x + 2y = 7

Solving the above system of equations, we get the value of x in terms of y as:

x = 7/2 - y/2

So, the eigenvector corresponding to λ = 7 is [7/2 - y/2, y].

Now, we can choose any value of y to find the corresponding eigenvector.

For suppose y = 2, then the corresponding eigenvector will be:

[7/2 - 2/2, 2] = [3, 2]

So, the associated eigenvector for eigenvalue λ = 7 is [3, 2].

The prefix associated with the multiplier 0.001 is "milli-."

The International System of Units (SI) uses prefixes to denote decimal multiples and submultiples of units. The prefix "milli-" corresponds to a multiplier of 0.001. Here's a stepwise explanation of how this prefix is determined:

1. Identify the multiplier: The given multiplier is 0.001.

2. Understand the prefix: The prefix "milli-" represents a factor of 1/1000 or 0.001.

3. Determine the prefix symbol: The symbol for "milli-" is "m." It is written in lowercase.

4. Attach the prefix: To express a unit with the multiplier 0.001, you attach the prefix "milli-" to the base unit. For example, if the base unit is meter (m), the millimeter (mm) represents 0.001 meters.

5. Other examples: The milligram (mg) represents 0.001 grams, the millisecond (ms) represents 0.001 seconds, and the milliliter (mL) represents 0.001 liters.

By using the "milli-" prefix, we can conveniently express values that are a thousandth of the base unit, allowing for easier comprehension and communication in various scientific and everyday contexts.

The diameter of a cartwheel is 2.1 m. Find the distance travelled when it completes 100 revolutions.

You need to find the circumference of the cartwheels first so that you know how much it would travel if her wheels revoluted 1 time. Circumference of circle = pi × d

1 revolution = 2.1pi

100 revolutions = 2.1pi × 100

Cost of fencing = 4 × 98pi

                          = 392pi

If we test H₀ : μ = 16 versus H₁ : μ ≠ 16 at α = 0.01, reject H₀ in favor of H₁. The correct answer is (a)

If the confidence interval for the population mean does not contain the hypothesized value in the null hypothesis, then we can reject the null hypothesis in favor of the alternative hypothesis.

In this case, the confidence interval is centered around 10.15, and it does not contain the hypothesized value of 16. Therefore, we can conclude that we have evidence to reject the null hypothesis at a significance level of 0.01 and accept the alternative hypothesis that the population mean is not equal to 16.

It is important to note that this decision is based on the confidence interval and significance level given in the question. If the confidence level or significance level were different, the decision might be different as well.

y1 = 2x + 4

y2 = 3x-9

y1 = y2

2x + 4 = 3x - 9

4 = x - 9

x = 13

--> Plug x back into an equation for y coordinate. I will be using y1.

2(13) + 4
