HELP NOW ASAP HURRY i don't got all day!!!!!!!!!!!!!
Anarel [89]

Answer:

15 3/4t^2 + 5 1/4

Explanation:

h(t)=-16t^2+400

We can add 400 then - 64 and show as 8^2

= h(t)=-16t^2+400 - 8^2  

But we also need to change 16t^2;

We divide 64 into 16 = 16/64 =0.25

and show 16t^2 changes by 0.25 = 1/4

15 3/4t^2 + 400-64

Can now look like

15 3/4t^2 + 5 1/4

As 5 1/4 = 64 x 5 1/4 = 336
