QuestionAn athlete releases a shot at 3030^{\circ} with height modeled by f(x)=0.01x2+0.6x+6.4f(x)=-0.01 x^{2}+0.6 x+6.4. Find max height and distance.

Studdy Solution

STEP 1

Assumptions1. The path of the shot is modeled by the function f(x)=0.01x+0.6x+6.4f(x)=-0.01 x^{}+0.6 x+6.4. . The height of the shot, f(x)f(x), is measured in feet.
3. The horizontal distance from the point of release, xx, is also measured in feet.
4. The shot is released at an angle of 3030^{\circ}.

STEP 2

The maximum height of the shot can be found by finding the vertex of the parabola represented by the function f(x)f(x).
The x-coordinate of the vertex of a parabola given by the equation f(x)=ax2+bx+cf(x) = ax^{2} + bx + c is given by b2a-\frac{b}{2a}.

STEP 3

Now, plug in the given values for aa and bb to calculate the x-coordinate of the vertex.
x=b2a=0.62(0.01)x = -\frac{b}{2a} = -\frac{0.6}{2(-0.01)}

STEP 4

Calculate the x-coordinate of the vertex.
x=0.62(0.01)=30x = -\frac{0.6}{2(-0.01)} =30

STEP 5

The x-coordinate of the vertex represents the horizontal distance from the point of release at which the maximum height occurs.Now, to find the maximum height, we substitute x=30x =30 into the equation f(x)f(x).

STEP 6

Substitute x=30x =30 into the equation f(x)f(x).
f(30)=0.01(30)2+0.6(30)+6.4f(30) = -0.01(30)^{2} +0.6(30) +6.4

STEP 7

Calculate the maximum height of the shot.
f(30)=0.01(30)2+0.6(30)+6.4=16f(30) = -0.01(30)^{2} +0.6(30) +6.4 =16The maximum height of the shot is16 feet, which occurs30 feet from the point of release.
