Answer:

y=-1/3x+8

Step-by-step explanation:

3x=y+3

y=3x-3

When it is perp find the reciprocal of the coefficient of x and flip the sign.

3x ---> -1/3x

y=-1/3x+b

Then plug in the (-3,9) to x and y

9=1+b

b=8

Substitute in the answers

y=-1/3x+8

Total money Gillian spend on both cotton shirts and wool shirts = $300

Cost of per cotton shirt = $15

Cost of per wool shirt = $ 20

According to question,

The number of wool shirts Gillian will buy will be at least 3, but less than half the number of cotton shirts she buys.

So, by option when we use the data of Option 'A'

Number of cotton shirts =13

Cost incurred on cotton shirt is given by

13×15=195

Number of wool shirts = 4

Cost incurred on wool shirt is given by

4×20=80

Total cost incurred on both the shirts is given by 195+80=275

If we use option 'B' we spend only $230

If we use option 'C' , it does not satisfy the question as it is mentioned in the question that number of wool shirt must be less than half of number of cotton shirt

If we use option 'D' , we spend $325 which is much higher than $300

Therefore, option A is the correct answer.

Answer:

l = 32.57, w = 24.43, h = 8.14

Step-by-step explanation:

volume = l*w*h

l = 4x

w = 3x

h = x

540 = 4x * 3x * x

540 = 12x^3

\(\sqrt[3]{540}\) = 8.14

l = 4x = 4(8.14) = 32.57

w = 3x = 3(8.14) = 24.43

h = x = 8.14

Step-by-step explanation:

98 adult tickets were sold on Saturday at the movie theatre.

To find the number of adult tickets sold on Saturday, we can set up a system of equations based on the given information. Let's denote the number of child tickets sold as C and the number of adult tickets sold as A.

From the problem, we know that the child admission price is $6.20, and the adult admission price is $9.30. The total number of tickets sold is 173, and the total sales amount is $1376.40.

We can set up the following equations:

Equation 1: C + A = 173 (the total number of tickets sold is 173)

Equation 2: 6.20C + 9.30A = 1376.40 (the total sales amount is $1376.40)

To solve this system of equations, we can use substitution or elimination methods. Let's use the substitution method.

From Equation 1, we have C = 173 - A. Substituting this value into Equation 2, we get:

6.20(173 - A) + 9.30A = 1376.40

Expanding and simplifying the equation, we have:

1071.6 - 6.20A + 9.30A = 1376.40

Combining like terms, we get:

3.10A = 304.8

Dividing both sides by 3.10, we find:

A = 98.4516

Since we cannot have a fractional number of tickets, we round A to the nearest whole number. Therefore, the number of adult tickets sold on Saturday is 98.

In summary, 98 adult tickets were sold on Saturday at the movie theatre.

It seems like there is a typo in the series notation. I assume the series you are referring to is ∑(2(-1)^n-1)/(12n^2 + 1) from n=1 to infinity. In this case, we can determine the sum using a well-known function and round the answer to four decimal places. Since the given series is an alternating series, we can use the Alternating Series Estimation Theorem to determine an approximation for the sum. The theorem states that if the absolute difference between consecutive terms is decreasing and the limit of the terms as n approaches infinity is zero, the approximation for the sum is accurate up to the first term that is less than or equal to the desired error bound (in this case, 0.0001). For this series, we can see that the absolute difference between consecutive terms decreases as n increases and the limit as n approaches infinity is zero. So, we can find the smallest value of n for which the term is less than or equal to 0.0001 and calculate the sum up to that term.

Answer:

the answer would be 211

Step-by-step explanation:

you simply add the length and width together to find perimeter. since you have the total perimeter and the length you would instead subtract the two.

292-81= 211

Answer:

68m

Step-by-step explanation:

The perimeter  of a rectangle with length  and width  is given by the following.

P=21+2w

We need to find w when P=292 m  and l+78m .

Using these values in the equation above, we'll solve for w.

P=21+2w

292=2(78)+2w

292=156+2w

136=2w

68=w

Subtracting 156  from both sides

Dividing both sides by  2

So the width of the parking lot is 68m

Question: Find the value of x.

Step-by-step explanation:

Given:

- Triangle R T S is sitting on a horizontal line

- Line S R extends through point Q to form exterior angle T R Q

- m∠RTS is (25 x)°, m∠TSR is (57 + x)° , m∠TRQ is (45 x)°

Lets find the value of x

∠TRQ is an exterior angle of Δ RTS at the vertex R

The opposite interior angles to vertex R are ∠RTS and ∠TSR

∴ m∠TRQ = m∠RTS + m∠TSR

m∠TRQ = (45 x)°

m∠RTS = (25 x)°

m∠TSR = (57 + x)°

Substitute these measures in the equation above

45 x = 25 x + 57 + x

45 x = 26 x + 57

19 x = 57

x = 3

The interest tax shield of 1.26% lowers Summit's WACC by 0.76%

Let’s calculate the interest tax shield on Summit Builders' debt. Interest tax shield = Interest expense x tax rate

Summit Builders’ debt is 1.50 times the value of its equity.

So, the total value of its capital is equal to 1 + 1.50 = 2.50

The weight of debt is equal to debt/(equity+debt) = 1.50/2.50 = 0.6

The weight of equity is equal to equity/(equity+debt) = 1/2.50 = 0.4

The interest expense = 6% of debt

The tax rate is given as 21%.

Therefore,Interest tax shield = Interest expense x tax rate= 6% x 21%= 1.26%

The interest tax shield from its debt lowers Summit's WACC by the following amount:

WACC = wdebt*Kd*(1-t) + wEquity*Ke= 0.6 * 6% * (1 - 21%) + 0.4 * Ke= 2.4% + 0.4 * Ke

The interest tax shield of 1.26% lowers Summit's WACC by:1.26% x 0.6 = 0.756%≈0.76%

Answer:

42 x is the answer of this question

a. The expected crop yield for a farm that receives 30 inches of rainfall in a state that does not experience high GDP growth is 172 - 5(30) + 12(0) + 7(30)(0) = 22 bushels of corn per acre.

b. The coefficient on the interaction term is 7.

This implies that the effect of rainfall on crop yield varies with high GDP growth. More specifically, when high GDP growth is zero (i.e. when there is no high GDP growth), the slope of the relationship between rainfall and crop yield is -5 (that is, for a one cm increase in rainfall, crop yield decreases by 5 bushels of corn per acre).

However, when high GDP growth is equal to one (i.e. when there is high GDP growth), the slope of the relationship between rainfall and crop yield is -5 + 7 = 2 (that is, for a one cm increase in rainfall, crop yield decreases by 2 bushels of corn per acre).

Yes, the coefficient for rainfall (B1) suffers from omitted variable bias. This is because more experienced farmers tend to select farms in locations with better rainfall, all other things being equal. Thus, the coefficient for rainfall in the linear regression model is affected by omitted variable bias.

In other words, rainfall is endogenous and correlated with the error term, since it is affected by an omitted variable (the farmer's experience). This leads to biased and inconsistent estimates of the coefficient for rainfall.

A function that satisfies the condition of having its square plus the square of its derivative equal to 1 is given by f(x) = sin(x).

The function f(x) = sin(x) has the property that its square, sin^2(x), is equal to 1 when added to the square of its derivative, \($\frac{d}{dx}\sin(x))^2 = \cos^2(x)$\).

This can be seen by directly evaluating the expression: \(sin^{2}(x) + cos^{2}(x) = 1\), which is a fundamental identity in trigonometry.

The sine function is periodic with a period of 2π, and its derivative, cosine function, also has the same period. This means that for any x, the function sin(x) and its derivative cos(x) will satisfy the given condition.

Geometrically, the sine function represents the y-coordinate of a point on the unit circle as the corresponding angle is varied. Its derivative, the cosine function, represents the rate of change of this y-coordinate with respect to the angle. The squares of the sine and cosine functions add up to 1, which is the square of the radius of the unit circle. This property is fundamental in trigonometry.
