Answer:
No, she can make less than $25000 according to the calculation
Step-by-step explanation:
Given the revenue function expressed as R = −0.5x2 − 200x, Margaret revenue will be at the maximum if dR/dx = 0
dR/dx = -2(0.5)x -200
dR/dx = -x -200
Since dR/dx = 0
-x-200 = 0
x = -200
Substitute x = -200 into the function.
R = −0.5x^2 − 200x
R = −0.5(-200)^2 − 200(-200)
R = -0.5(40000)+40000
R = -20000+40000
R = 20000
This means that the revenue for the year is $20,000 which shows that her revenue cannot be at least $25000 for that year but she could make less than $25000
Answer: (9,7)
Step-by-step explanation:
By definition, a rectangle is a quadrilaleral that has two pairs of equal sides.
When you plot the points given in the problem you obtain the points shown in the first figure.
Then, keeping the definition above on mind, the fourth vertex must be at coordinates (9,7), as you can see in the second figure.
