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:
this answer is -1.8
Step-by-step explanation:
because you add and subtract all of them
You find the litres of petrol you want and go up until you find where the line crosses this point and then see how far you can travel on the left so
a is 15km
and b is 39km
Answer:
11. C
Step-by-step explanation:
11.
y=1.75x+10
y=1.75(10.25)+10
So it's number C.
12.
y=1.75(10.25)+10
y=27.9375
He will collect $27.94
This is rounded.
