Aperson standing close to the edge on top of a 72-foot building throws a ball vertically upward. the quadratic function h(t)=−16t2+84t+72h(t)=-16t2+84t+72 models the ball's height about the ground, h(t), in feet, t seconds after it was thrown.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
