Answer:

Step-by-step explanation:
Midpoint formula is
---------------(1)
Here

Substituting values in equation (1)


-16t^2+400=0
16t^2=400
take square root on both sides.

4t=20
t=20/4
t=5

Answer:
- left 1 unit
- down 2 units
Step-by-step explanation:
The transformation g(x) = f(x -h) +k is a translation of f(x) to the right by h units and up k units.
1. h = -1, so the graph of g(x) is the graph of f(x) shifted left 1 unit. (blue)
__
2. k = -2, so the graph of g(x) is the graph of f(x) shifted down 2 units. (green)
