Answer:

1308.6 feet

Step-by-step explanation:

Given is the quadratic equation

y= -16x^2 + 275x + 127

It has the maximum height at its vertex, x-coordinate of which is calculated by the formula:

x = -b/2a
x = -275/2(-16) = 8.6 rounded to the nearest tenths

Calculating the highest point:

y = -16(8.6)^2 + 275(8.6) + 127 = 1308.6 feet rounded to the nearest tenths
