Josh hit a baseball straight up into the air. The equation below describes the height of the ball (h), in meters, as a function of time (t) in seconds.

h(t) = -9.8t² + 30t + 1.5

What is the height of the ball after 3 seconds?

i keep getting -195.9

h(3) = -9.8(9) + 30(3) + 1.5
= 3.3

I don't have the foggiest clue how you came up with -195.8
I tried different permutations of the arithmetic, but no luck.
h(t) = -9.8(3)^2+30(3)+1.5 = 3.3 meters
