A model rocket is launched into the sky. The quadratic function y =-16x2 + 32x models the height in feet of
the rocket after x seconds. How long is the rocket in
the air?

he kicked it up? is this the answer ?

step-by-step explanation:

150.6

all i did was i multiplied 5.02 by 30

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74

this is a tricky question, lol,   but i think the answer is 100,000.
