The height y (in feet) of a punted football is given by -16/2025x^2 + 9/5x + 2.5 where x is the horizontal distance (in feet) from the point at which the ball is punted. (a) how high is the ball when it is punted? . (b) what is the maximum height of the punt? (round your answer to two decimal (c) how long is the punt? (round your answer to two decimal places.)

for (b) find the line of symmetry of the curve

for a parabola

ax2+bx+c

the line of symmetry is

x=−b2a

when you get this value substitute it for the max height

(c) you need to find then the height is 0

so let H(t) = 0 and solve for x... maybe the general quadratic formula is easiest...

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
