This is the equation of an upside down parabola, so the maximum height will be at the vertex. To find the vertex, we'll use the formula for the x-coordinate and then solve for the y-coordinate.
[tex]x=\frac{-1.53}{2*-.03}=25.5[/tex]
Plugging this into the given formula:
[tex]y=-0.03(25.5)^2+1.53(25.5)=19.5075[/tex]
Since it asks us to round, the maximum height would be 20 yards. To find how far the football travels in total, we need to set the equation equal to 0 and find the roots:
[tex]0=-0.03x^2+1.53x=x(-0.03x+1.53)[/tex]
Then by the zero product property (or the no zero divisors rule), we have:
[tex]x=0[/tex] (this is the x value where the ball is kicked from)
[tex]-0.03x+1.53=0[/tex]
[tex]-0.03x=-1.53[/tex]
[tex]x=51[/tex]
So the ball travels 51 yards in total.

Answer:
Maximum height achieved by football = 25.5 yards.
Distance traveled by football 51 yards.
Step-by-step explanation:
Path of a football kicked by a field goal kicker can be modeled by the equation y = -0.03x² + 1.53x.
Where x represents horizontal distance and y represents height of the football.
For maximum, height we will find the [tex]\frac{dy}{dx}[/tex] ( derivative ) of the equation and equate it to zero.
[tex]\frac{d(y)}{dx}[/tex] = [tex]\frac{d}{dx}[/tex] (-0.03x² + 1.53x )
[tex]\frac{dy}{dx}[/tex] = -0.03 × 2x + 1.53
By putting [tex]\frac{dy}{dx}[/tex] = 0
-0.06x + 1.53 = 0
0.06x = 1.53
x = [tex]\frac{1.53}{0.06}[/tex] = 25.5 yards
Therefore, maximum height achieved by the ball is 25.5 yards.
Now for horizontal distance covered by ball y should be 0
-0.03x² + 1.53x = 0
x ( 1.53 - 0.03x ) = 0
0.03x = 1.53
x = [tex]\frac{1.53}{0.03}[/tex] = 51 yards.
Football was kicked 51 yards.
