Alex threw a ball into a basketball hoop. The height of the ball, in feet, is represented by the function h(t)=-8(t-2)^2+13, where t is time in seconds. From what height did Alex throw the ball?
Please show all work and any incorrect or incomplete answers will be reported.

The answer to your question is Alex threw the ball from 45.

Step-by-step explanation:

function             h(t) = 8(t - 2)² + 13

time = t = [seconds]

If we need to know the height from which Alex threw the ball, we need to consider that the time was zero, nothing has happened yet.

Evaluate the function when t = 0

                         h(0) = 8(0 - 2)² + 13

Simplification

                         h(0) = 8(-2)² + 13

                         h(0) = 8(4) + 13

                         h(0) = 32 + 13

                        h(0) = 45                    

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
