Think about it think 6x5 or higher then you will get you answer by doing that
Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :

We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0

So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.
Answer:
7
Step-by-step explanation:
If J is Joan's current age and E is Ellen's current age, then:
J = E + 5
(J - 3) + (E - 3) = 17
Solve the first equation for E:
E = J - 5
Substitute into the second:
(J - 3) + (J - 5 - 3) = 17
J - 3 + J - 8 = 17
2J - 11 = 17
2J = 28
J = 14
Joan is 14, so in 7 years, she will be 21.
The first part is 1325
10 x 35=350
15 x 65=975
The you add them which equals 1325
r=13/2
After I solved it it was kinda easy
