Charlize wants to measure the depth of an empty well. She drops a ball into the well and measures how long it takes the ball to hit the bottom of the well. She uses a stopwatch, starting when she lets go of the ball and ending
when she hears the ball hit the bottom of the well. The polynomial
h = -167 + 6 represents how far the ball has fallen after t seconds.
4. How far has the ball fallen after one second?
5.
Charlize's stopwatch measured a time of 3.2 seconds when the ball hit the
bottom of the well. How deep is the well?

Identify the function that contains the data in the following table: x     -2         0         2         3         5     f(x)     5         3         1         2         4     possible answers: f(x) = |x| + 1 f(x) = |x - 2| f(x) = |x - 2| - 1 f(x) = |x - 2| + 1

Look at the example below which shows how the product property of radicals is used to simplify a radical. use the product property of radicals to simplify the following radical.

Lian is deciding which of two gyms to join. each gym charges a monthly rate plus a one-time membership fee. lian correctly wrote and solved a system of linear equations by substitution to compare the costs of the memberships. in her work, she substituted an expression for one variable and solved for the other. this resulted in the equation 75 = 75. what can lian conclude? one gym charges $75 per month. each gym charges $75 per month both gyms charge the same monthly rate and the same membership fee. both gyms charge the same monthly rate, but not the same membership fee.
