Audrey throws a ball in the air, and the path the ball makes is modeled by the parabola

y = −0.018(x − 20)^2 + 8 , measured in feet.

a. What is the maximum height the ball reaches,

b. How far (horizontally) from Audrey does is the ball at its maximum height?

c. How far does the ball travel before it hits the ground?

d. How high is the ball after 3 seconds?

An objects motion is described by the equation d= 4sin (pi t) what will the height of the object be at 1.75 seconds?

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
