Step-by-step explanation:
Given is the quadratic equation
y= -16x^2 + 275x + 127It has the maximum height at its vertex, x-coordinate of which is calculated by the formula:
x = -b/2ax = -275/2(-16) = 8.6 rounded to the nearest tenthsCalculating the highest point:
y = -16(8.6)^2 + 275(8.6) + 127 = 1308.6 feet rounded to the nearest tenthsОтвет:
Pretty suree its B but it is hard
