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?

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
