What is Straight line?

A line with no curve is called a straight line.

Given that;

One endpoint of a line = (-3, 7)

Midpoint of a line = (5, 2).

Now, Let the other endpoint of a line = (x, y)

Then, Other endpoint is solve by the definition of midpoint of two points as;

(x + (-3) / 2 , y + 7 / 2 ) = (5, 2)

(x - 3 / 2 , y + 7 / 2) = (5, 2)

By compare we get;

x - 3/ 2 = 5

x - 3 = 2 * 5

x - 3 = 10

x = 10 + 3

x = 13

And,  

y + 7 / 2 = 2

y + 7 = 2 * 2

y + 7 = 4

y = 4 - 7

y = -3

Hence, The another endpoint of a line is (13, -3).

Okay, see, one or two questions I would help but doing your entire homework/test/quiz or whatever it is I don't think so. Why don't you at least try and then maybe i'll help.

Step-by-step explanation:

The correct polynomial in standard form obtained on multiplying the polynomials is -3y^8-3y^6+3y^4+90y^3+3y^2+90y.

A polynomial's standard form is stated by writing the greatest degree of terms first, then the next degree, and so on. f(x) = anxn + an-1xn-1 + an-2xn-2 +... + a1x + a0 is the usual form of a polynomial, where x is the variable and ai are coefficients.

By multiplying the coefficients we get,

(-3y^3 – 3y) (y^5 – 30 – y)

=> -3y^3(y^5-30-y)-3y(y^5-30-y)

=>-3y^8+90y^3+3y^4-3y^6+90y+3y^2

By converting to standard form of polynomial we get,

f(x)=-3y^8-3y^6+3y^4+90y^3+3y^2+90y.

The correct polynomial in standard form obtained on multiplying the polynomials is -3y^8-3y^6+3y^4+90y^3+3y^2+90y.

Step-by-step explanation:

this creates 2 similar triangles.

that means all angles are the same. and all the side lengths of one triangle correlate to the side lengths of the other triangle by the same multiplication factor.

2 × f = 5

f = 5/2 = 2.5

now the same factor applies to the relation of the heights :

5'4" × 5/2

to help us, let's convert her height into a fraction too.

1 ft = 12 in

4 in = 1/3 ft

5'4" = 5 1/3 ft = 16/3 ft

16/3 × 5/2 = 80/6 = 40/3 = 13 1/3 ft = 13'4"

so, the tree is 13 ft and 4 inches tall.

Answer:

6.58 miles per hour

Step-by-step explanation:

Let the mass and speed be represented by m and s respectively. So that,

m \(\alpha\) \(s^{5}\)

m = k\(s^{5}\)

where k is the constant of proportionality.

For a certain river, speed = 4 miles per hour.

m = k \((4)^{5}\)

m = 1024k ............ 1

In order to transport particles that are 12 times as massive as usual;

12m = k\(s^{5}\)

m = \(\frac{ks^{5} }{12}\) ............. 2

Thus,

\(\frac{ks^{5} }{12}\) = 1024 k

\(s^{5}\) = 12 x 1024

   = 12288

\(s^{5}\) 12288

s = \(\sqrt[5]{12288}\)

  = 6.5750

s = 6.58 miles per hour

Therefore, its speed must be approximately 6.58 miles per hour.

The value of a home increases by 7%each year, by compounding the value of the home doubles approximately once each decade.

Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.

It is given by the formula,

A=P(1+r)^t

where A is the value after t period of time,

P is the value of the asset at the beginning, and,

r is the rate of interest.

The value of the home doubles once each decade.

Given to us

The value of a home increases by 7% each year.

As it is given that the value of a home increases by 7% each year, therefore, the value of the home is compounding every year.

We know the formula of compounding,

A=P(1+r)^t

Why does the value doubles?

Now, let's assume a house whose value is 'P' today, therefore, substitute the value of the house in the formula of compounding,

A=P(1+r)^t

Substitute the rate at which the value is increasing,

A=P(1+0.07)^t

We know that in a decade there are 10 years,

A=P(1+0.07)^10=P(1.07)^10

=1.967P

Approximately

=2P

As we can see that the value of the home is almost 2 times the 'P' therefore, twice the value of the home at the beginning.

Hence, the value of the home doubles once each decade.

Answer:

The original price is $40.00.

Step-by-step explanation:

I am not sure what that given equation is.

But here is the correct answer and steps.

The marked down price is 75% of the original price.

The final price is 90% of the marked down price.

Lets say

\(T\) = Final Price

\(O\) = Original Price

We can write

\(T=(0.75*O)*(0.9)\)

Multiply \(0.9\) by \(0.75\).

\(T=0.675*O\)

We are given the final price. Lets substitute 27.00 for \(T\).

\(27.00=0.675*O\)

Divide both sides of the equation by \(0.675\).

\(40.00=O\)

The solution to the given differential equation is y(0.2) = 1.1188.

To solve the given differential equation dy/dt = √(x² + y) with the initial condition y(0) = 0.8, we can use the numerical method known as the Euler's method.

The Euler's method approximates the solution by taking small steps of size h in the independent variable (t) and approximating the derivative at each step.

Given that the range is x = 0.2 da to a = 0.2 with a step size of h = 0.2, we can start at x = 0.2 and compute the values of y at each step.

Let's perform the calculations step by step:

Step 1:

x₀ = 0.2, y₀ = 0.8

Step 2:

x₁ = x₀ + h = 0.2 + 0.2 = 0.4

y₁ = y₀ + h * √(x₀² + y₀) = 0.8 + 0.2 * √(0.2² + 0.8) = 0.8 + 0.2 * √(0.04 + 0.64) = 0.8 + 0.2 * √0.68 ≈ 0.8843

Step 3:

x₂ = x₁ + h = 0.4 + 0.2 = 0.6

y₂ = y₁ + h * √(x₁² + y₁) = 0.8843 + 0.2 * √(0.4² + 0.8843) = 0.8843 + 0.2 * √(0.16 + 0.7811) = 0.8843 + 0.2 * √0.9411 ≈ 0.9624

Step 4:

x₃ = x₂ + h = 0.6 + 0.2 = 0.8

y₃ = y₂ + h * √(x₂² + y₂) = 0.9624 + 0.2 * √(0.6² + 0.9624) = 0.9624 + 0.2 * √(0.36 + 0.9259) = 0.9624 + 0.2 * √1.2859 ≈ 1.0394

Step 5:

x₄ = x₃ + h = 0.8 + 0.2 = 1.0

y₄ = y₃ + h * √(x₃² + y₃) = 1.0394 + 0.2 * √(0.8² + 1.0394) = 1.0394 + 0.2 * √(0.64 + 1.0799) = 1.0394 + 0.2 * √1.7199 ≈ 1.1188

The solution to the given differential equation for the range x = 0.2 da to a = 0.2, with a step size of h = 0.2, is approximately:

y(0.2) ≈ 1.1188.

The equation of line is y = ( 3/4 )x + 2

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P = P ( 8 , 8 )

Let the second point be Q = Q ( 4 , 5 )

Now , the slope of the line between the two points is

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 5 - 8 ) / ( 4 - 8 )

Slope m = -3/-4

Slope m = 3/4

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

Multiple regression analysis is a statistical technique used to explore and quantify the relationship between a dependent variable and multiple independent variables. It allows researchers to examine how changes in one or more independent variables impact the dependent variable, while controlling for the effects of other variables. By estimating the coefficients for each independent variable, the analysis provides insights into the strength, direction, and significance of their relationships with the dependent variable. This method is commonly employed in various fields, such as economics, social sciences, and business, to understand complex relationships and make predictions based on the interplay of multiple factors.

The decision is: failure to reject the null hypothesis (frh0).

To determine if there is evidence to support the retailer's belief that salespersons with a college degree have higher average sales, we can perform a

hypothesis test

. The null hypothesis (H0) is that there is no difference in the average sales between salespersons with and without a college degree. The alternative hypothesis (Ha) is that the average sales are greater for salespersons with a college degree.

Let's calculate the p-value and make a decision at the 5% level.

1. Set up the hypotheses:
H0: Average sales for salespersons with a college degree = Average sales for salespersons without a college degree
Ha: Average sales for salespersons with a college degree > Average sales for salespersons without a college degree

2. Calculate the test statistic:
The test statistic used for comparing two means is the

t-test

. We can calculate it using the formula:

t = (x1 - x2) / sqrt((s1^2 / n1) + (s2^2 / n2))

where:
x1 = average weekly sale for salespersons with a college degree = $3422
x2 = average weekly sale for salespersons without a college degree = $3255
s1 = standard deviation for salespersons with a college degree = $468
s2 = standard deviation for salespersons without a college degree = $642
n1 = sample size for salespersons with a college degree = 31
n2 = sample size for salespersons without a college degree = 35

Plugging in the values, we get:

t = (3422 - 3255) / sqrt((468^2 / 31) + (642^2 / 35))
t = 167 / sqrt((218,664 / 31) + (412,164 / 35))
t ≈ 167 / sqrt(7059.48 + 11776.4)
t ≈ 167 / sqrt(18835.88)
t ≈ 167 / 137.34
t ≈ 1.215

3. Find the p-value:
Using the t-distribution table or a statistical software, we can find the p-value associated with the calculated t-value. For a one-tailed test with a degree of freedom (df) of 31 + 35 - 2 = 64, the p-value is approximately 0.114.

4. Make a decision:
Since the p-value (0.114) is greater than the significance level of 0.05, we fail to reject the null hypothesis. There is not enough evidence at the 5% level to support the retailer's belief that salespersons with a college degree have higher average sales.

Therefore, the decision is: failure to reject the null hypothesis (frh0).
