A ball is projected vertically upward from the surface of the earth with an initial speed of 49 meters per second. The ball reaches its maximum height in 5.0s. What is the vertical velocity of the ball when it strikes the ground A. 0 m/s
B. -9.8m/s
C. 49m/s
D.-49m/s

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

idk

step-by-step explanation:

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 %
