Answer:

$45 is the price that provide the maximum revenue

Step-by-step explanation:

Let x be the number of times the price increase

A company can sell 2000 magazine subscriptions , for each price increase they sell 200 few subscriptions. (2000-200x) for x  times increase.

for each $5 increase, the cost becomes 40+5

For x times increase the cost becomes 40+5x

Revenue is cost time the number of magazines

R(x)= (2000-200x)(40+5x)

R(x)=-1000x^2+2000x+80000

R(x)=-1x^2+2x+80

a=-1  and b = 2

To get maximum revenue find out the vertex

x=\frac{-b}{2a} =\frac{2}{2(-1)} =1

price is 40+5x= 40+5(1)= 45

so $45 is the price that provide the maximum revenue

The value of the variable x will be 37°. Then the measure of the angle ∠QNP will be 105°.

<h3>What is an angle?</h3>

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The measure of angles ∠MNQ = (2x + 1)° and ∠QNP = (3x - 6)°.

Then the value of x will be

We know that the angles ∠MNQ and ∠QNP are supplementary angles. Then the value of the variable x will be

∠MNQ + ∠QNP = 180°

(2x + 1)° + (3x - 6)° = 180°

5x - 5° = 180°

5x = 185°

x = 37°

Then the measure of the angle ∠QNP will be

∠QNP = [3(37) - 6]°

∠QNP = 111° - 6°

∠QNP = 105°

The value of the variable x will be 37°. Then the measure of the angle ∠QNP will be 105°.

More about the angled link is given below.

Write the equation of the line with a slope of 1/2 that passes through the point (-6,10)​
Katen [24]

Answer:

An equation is

y =  \frac{1}{2} x + 13

.

Step-by-step explanation:

☆Since since we're given the slope, all we need to do is find the y-intercept.

☆The slope-intercept formula is: y = mx + b.

☆We are going to plug in according to the formula.

y = mx + b \\  \\ 10 =  \frac{1}{2} ( - 6) + b \\ 10 =  - 3 + b \\  \frac{ + 3 =  + 3 \:  \:  \:  \:  \:  \:  \:  \:  \: }{13 = b \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: }

☆We have everything we need, so now we put it together.
