# A ball is shot out of a cannon. The height of the ball, h in meters, as a function of the time, t in seconds, since it was shot is given by the equation h= -5t^2 +30t +1. What is the height of the ball after 1 second?

$h = \text{26 m}$

#### Explanation:

Since this is a function of $t$, time, the height when $t = 1$ can be found by plugging in $1$ for $t$.

$h = - 5 {\left(1\right)}^{2} + 30 \left(1\right) + 1$

$h = - 5 + 30 + 1$

$h = \text{26 m}$
