a toy rocket is shot vertically into the air from a launching pad 6 feet above the ground with an initial velocity of 160 feet per second. The height h, in feet, of the rocket above the ground at t seconds after launch is given by the function h(t)=-16square+160t+6. how long will it take the rocket to reach its maximum height? what is the maximum height?

The height \( h(t) \) of the rocket is given by the quadratic function:

\[
h(t) = -16t^2 + 160t + 6
\]

To find the time it takes for the rocket to reach its maximum height, we need to determine the vertex of the parabola. For a quadratic function \( h(t) = at^2 + bt + c \), the time \( t \) at which the maximum or minimum occurs is given by:

\[
t = \frac{-b}{2a}
\]

In this case, \( a = -16 \), \( b = 160 \), and \( c = 6 \). Plugging in these values:

\[
t = \frac{-160}{2(-16)} = \frac{-160}{-32} = 5 \text{ seconds}
\]

So, the rocket reaches its maximum height 5 seconds after launch.

### Finding the Maximum Height:

To find the maximum height, substitute \( t = 5 \) back into the height function:

\[
h(5) = -16(5)^2 + 160(5) + 6
\]

\[
h(5) = -16(25) + 160(5) + 6
\]

\[
h(5) = -400 + 800 + 6 = 406 \text{ feet}
\]

### Conclusion:
- The rocket reaches its maximum height at \( t = 5 \) seconds.
- The maximum height is 406 feet.
