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.
Answer:
Step-by-step explanation:
Girls:Total number of people
89:235
89:47
1. 2/7
2. 2/15
3. 5/24
4. 2/11
First of all, 15 minutes is 1/4 of an hour. So 8:15 is 8.25 hours.
(8.25 hours/day) x ( 9 $/hour) x (5 days) = $371.25
I think the answer would be be C.
