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

The equation in the form 0 = ax^2 + bx + c is:
0 = x^2 + x + 2
The discriminant = b^2 - 4ac
Discriminant = (1)^2 - 4(1)(2)
= 1 - 8
= -7
C: 288 feet
94 + 50 = 144
144 x 2 = 288
30 mph for 0.5 hrs = 15 miles
80 mph for 2 hours = 160 miles
160 +15 = 175 miles total
Close to zero and unlikely
