The height hin feet of a person on a waterslide is modeled by the function h(t)=-0.02562 -0.51 +50, where t is the time in seconds. At the bottom of the slide, the person
lands in a swimming pool.
a. To the nearest second, how long does the ride last?
b. What is the y-intercept, and what does it represent?
c. What is the height of the person above the swimming pool after 21 seconds?

which expression represents the approximate length of bc?

step-by-step explanation:

answer: a) 56% women

b)44% men

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
