Question

An object is launched at 19.6 m/s from a height of 58.8 m. The equation for the height (h) in terms of time (t) is given by h(t) = -4.9t2 +19.6t + 58.8. What is the object's maximum height?
A. 58.8
B. 194.04
C. 78.4
D. 117.6

Answer 4

it's not A, you need to find the vertex, not the y-intercept

Answer 5

the y coordinate of the vertex

Answer 6

Find the vertex of that parabola.

Answer 7

It couldn't be A because it was launched from a height of 58.8 so it would have to go higher than that.

Answer 8

okay now Im getting C?

Answer 9
