The height y (in feet) of a ball thrown by a child is ; y= -1/12x^2 + 6x +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 childs hand? feet

b) What is the maximum height of a ball? ___ feet

c) How far from the child does the ball strike the ground? ___ feet

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.

step-by-step explanation:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
