Holly plays tennis on the school tennis team. She can hit a tennis ball really high in the air. She learned
that the quadratic equation below could be used to
determine the height of a tennis ball after it was hit
with a tennis racket.
y = -6x2 + 36x
She defined the variables for us:
y = the height of the tennis ball in feet
x = seconds after the ball is hit with the i
How long does it take for the ball to hit the ground
in seconds?

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

wait nvm i know the correct answer now its 100%   81 square feet
