Aball is thrown in the air from a ledge. it's height in feet represented by f(x)=16(x^2-6x-7), where x is the number of seconds since the ball has been thrown. the height of the ball is 0 feet when it hits the ground. how many seconds does it take the ball to reach the ground?

Step-by-step explanation:

Since we know that the height is 0, we can figure out how long it took the ball to reach the ground by setting and solving for :

Because time can only be positive, the answer is 7 seconds.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
