Y=-x^2+20x-64 what is the max height

36

Step-by-step explanation:

The maximum height is the y-coordinate of the vertex

given a quadratic in standard form : ax² + bx + c : a ≠ 0

then the x-coordinate of the vertex is

= -

y = - x² + 20x - 64 is in standard form

with a = - 1, b = 20 and c = - 64, hence

= - = 10

substitute x = 10 into the equation for y

y = - (10)² + 20(10) - 64 = 36 ← max height

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?

i believe the answer is 323 ft
