Step-by-step explaation:
c(80) =40x80 +150 =3350 üretim için 80 parçanın maliyeti
satış için ise : R(80) 0.5(80-110)^2+6,050 = 456
3350-456=2983.95 kar ederler

Question:
A fastball is hit straight up over home plate. The ball's height, h (in feet), from the ground is modeled by h(t)=-16t^2+80t+5, where t is measured in seconds. Write an equation to determine how long it will take for the ball to reach the ground.
Answer:

Step-by-step explanation:
Given

Required
Find t when the ball hits the ground
This implies that h(t) = 0
So, we have:

Reorder

Using quadratic formula, we have:

Where

So, we have:




This gives:
or 
or 
or 
But time can not be negative.
So, we have:


<em>Hence, time to hit the ground is 5.0625 seconds</em>
The answer to this question is option <u>C. </u><u><em>104
°</em></u>
