12h + 20t = income
1.5(h + t) + 7h + 9t + 500 = expenses
12h + 20t - 1.5(h + t) + 7h + 9t + 500 > 0
It took 14 minutes
70 degrees +(14minutes times 20degrees) = 350 degrees.

Answer:
D
Step-by-step explanation:
4 x^ + 36=0
4x( x + 9) =0 provd
The maximum value can be determined by taking the derivative of the function.
(dh/dt) [h(t)] = h'(x) = -9.8t + 6
Set h'(x) = 0 to find the critical point
-9.8t + 6 = 0
-9.8t = -6
t = 6/9.8
Plug the time back into the function to find the height.
h(6/9.8) = -4.9(6/9.8)^2 + 6(6/9.8) + .6
= 2.4
And I don't understand your second question.
