Modeling with Quadratic Equations Answers
The product of two numbers is 450. The first number is half the second number. Which equation can be used to find x, the greater number?
A computer company makes a rectangular screen with a diagonal of 20 inches. The width of the screen is 4 inches less than its length.
A rectangle’s length is 2 units more than twice its width. Its area is 40 square units. The equation w(2w + 2) = 40 can be used to find w, the width of the rectangle.
The product of two numbers is 713. The first number is 9 more than the second number. Which equation can be used to find x, the greater number?
An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled using h(t)=144-16t2.How many seconds will it take the object to reach the ground?
A rocket is launched into the air. The projectile motion of the rocket can be modeled using h(t) = 112t –16t2, where t is the time since launch in seconds and h(t) is the height of the rocket at time t.

The projectile motion of an object can be modeled usings(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s2.
