Answer:
The revenue function is given as
R(x) = 500x - 0.8x²
Step-by-step explanation:
Given the Price equation
P = 500 - 0.8x
and the Cost equation
C(x) = 4x + 6000
The revenue function is given as
R(x) = xP
But P = 500 - 0.8x
So
R(x) = x(500 - 0.8x)
= 500×x - 0.8x×x
= 500x - 0.8x²
R(x) = 500x - 0.8x²
Answer. D) -1.9 and 2.6 are the solutions because when x=-1.9 and x=2.6 we have two points where the graph are cut. That is to say we have the same points in both graphs.

Answer:
Step-by-step explanation:
There are many ways this could be done, but the simplest way is to divide 18 into 72. That gives 4. So each plot is 4 * 20 = 80 m^2
If you are willing to use fractions, the answer could be 20*72 / 18 = 8 * 10 which is more feasible and still gives 80, but the land may not permit it. However math will.
It's hard to give an exact answer when it is this open ended.
