A soccer ball is kicked from ground level. The function y = −12x(x − 4) shows the height (in feet) of the ball, where x is time (in seconds). After how many seconds will the ball hit the ground?

4 seconds

Step-by-step explanation:

On the ground, height = 0

-12x(x - 4) = 0

x = 0, 4

It was on the ground initially at x = 0, and again at x = 4

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
