The height y (in feet) of a ball thrown by a child is
y=−1/12x^2+4x+3
where x is the horizontal distance in feet from the point at which the ball is thrown.
(a) how high is the ball when it leaves the child's hand? (hint: find y when x=0)
your answer is y=
(b) what is the maximum height of the ball?
(c) how far from the child does the ball strike the ground?

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
