A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot. y=−16x 2+124x+110

To find the maximum height of the rocket, we use the given quadratic equation:

\[
y = -16x^2 + 124x + 110
\]

This is a parabola opening downwards because the coefficient of \(x^2\) is negative (\(-16\)). The maximum height is achieved at the vertex of the parabola.

### Step 1: Formula for the vertex
The time at which the maximum height occurs is given by:

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

Here, \(a = -16\), \(b = 124\), and \(c = 110\).

\[
x = -\frac{124}{2(-16)} = \frac{124}{32} = 3.875 \, \text{seconds}.
\]

### Step 2: Calculate maximum height
Substitute \(x = 3.875\) into the equation to find the maximum height \(y\):

\[
y = -16(3.875)^2 + 124(3.875) + 110
\]

First, calculate each term:
\[
(3.875)^2 = 15.015625, \quad -16(15.015625) = -240.25, \quad 124(3.875) = 480.5
\]

\[
y = -240.25 + 480.5 + 110 = 350.25 \, \text{feet}.
\]

### Final Answer:
The maximum height of the rocket is **350.3 feet** (to the nearest tenth).
