1 answer:
Answer:
5.2seconds
Step-by-step explanation:
Fredrick threw a ball from the top of a building. The height of the ball, in feet, after it is thrown is modeled by the function
The modeled function is given as
h(t) = –16t^2 +64t + 100,
We can see this is a quadratic equation, we can solve using quadratic formula, Below
= -b±(√b^2 -4ac)/2a
Where
a=-16, b=64, c=100
FROM THE ATTACHMENT
We have too answers t= -1.20s and t=5.20s
Therefore,it take 5.20s for the ball to reach the ground (h=0). Because "t" cannot be negative here
