Sloane kicked a soccer ball at a speed of 36 feet per second. If the ball never leaves the ground, then it can be represented by
the function H(t) = - 16t2 + 36t. Determine the time the ball traveled.
t = 0.44 seconds
Ot = 2.25 seconds
t = 16 seconds
t = 36 seconds

t = 2.25 seconds

Step-by-step explanation:

Let

x ----> the time in seconds that the ball traveled

H(t) ---> the height of the ball in feet

we have

we know that

When the ball hit the ground, the height of the ball is equal to zero

so

To find out the time the ball traveled, equate the function H(t) to zero

For H(t)=0

solve for t

Factor -16t

The solutions are

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
