Answer:
It comes from correct solution steps and is not a valid solution of the equation.
Step-by-step explanation:
It’s answer C f of x will increase and will pass g of x. Also because f(x) is linear and g(x) is exponential.
Answer: 0.0655
Step-by-step explanation: if you divide 6.55 by 100, you I’ll get 0.0655 .
Answer:
a) Y(x) = {900, x≤30; 900-40(x-30), x>30}
b) T(x) = {900x, x≤30; 2100x-40x², x>30}
c) dT/dx = {900, x≤30; 2100-80x, x>30}
Step-by-step explanation:
a) The problem statement gives the function for x ≤ 30, and gives an example of evaluating the function for x = 35. So, replacing 35 in the example with x gives the function definition for x > 30.

__
b) The yield per acre is the product of the number of trees and the yield per tree:
T(x) = x·Y(x)

__
c) The derivative is ...

_____
The attached graph shows the yield per acre (purple, overlaid by red for x<30), the total yield (black), and the derivative of the total yield (red). You will note the discontinuity in the derivative at x=30, where adding one more tree per acre suddenly makes the rate of change of yield be negative.
Part A: 16x=M
Part B: 16x+TY=M
Part C: 16x=580
