Chapter 4 Section 5.BSolving Quadratics by Finding Square Roots
In this assignment, you will be able to...
1.Solve a quadratic equation.
2. Model a dropped object with a quadratic function.
A cliff diver dives off a cliff 40 feet above water. Write an equation given the
diver's height h (in feet) above water after t seconds. How long is the diver in
the air?
9.)
10.) An object is dropped from a building 200 feet above the ground. How long
until the object hits the ground?
11.) On any planet, the height h (in feet) of a falling object t seconds after it is dropped
can be modeled by
where
is the object's initial height (in feet)and g is the acceleration (in feet per second squared) due to
gravity. Find the time it takes a rock dropped from a height of 150 feet to hit the surface on
Mars where
13.) The path of a basketball travels along a path that is modeled by
where x is the time in seconds and y is the height. After how many seconds is
the ball at it's maximum height and what is that height?
