Answer:
t = 2secs
Step-by-step explanation:
Given the height above the surface expressed as h = -16t^2 + 64 t + 80.
The velocity of the rocket at its maximum height is zero. Hence;
v(t) = dy/dt = 0
dy/dt = -32t + 64
0 = -32t + 64
32t = 64
t = 64/32
t = 2secs
Hence the rocket will hit the lake after 2 secs
1) (2,-2)
3) (-1,5)
5) (1,-3)
2) (2,2)
6) (-3,-3)
Hey there!
When you see the decimal that looks like (0.3) this would be called a terminating decimal, which is a decimal that always have extra numbers at the end.
For example:
2.(3)
1.(67)
The number's that are in the parenthesis are the terminating numbers.
Hope this helps you!
