Chapter 4 Section 5.B Solving 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.

1.) Solve the equation.

2.) Solve the equation.

3.) Solve the equation.

4.) Solve the equation.

5.) Solve the equation.

Solve the equation. 6.)

Solve the equation. 7.)

Solve the equation. 8.)

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

12.)Graph the equation Label the vertex and axis of symmetry

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?

14.)Solve the equation
