Suppose you drop a ball from a window 15 meters above the ground. the ball bounces to 70% of its previous height with each bounce. what is the total number of meters (rounded to the nearest tenth) the ball travels between the time it is dropped and the eighth bounce?
a. 76.4
b. 79.2
c. 32.1
d. 64.2

For the given quadratic equation convert into vertex form, find the vertex and find the value for x=6 y=-2x^2+2x+2

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
