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

Answer:
yes they are perpendicular
hope this helps
have a good day :)
Step-by-step explanation:
Answer:
A. (3/2, 6)
Step-by-step explanation:
Use the substitution method:
8x + y = 18 and y = 4x
8x +4x = 18
12x = 18
x = 18/12 = 3/2
y = 4x
= 4(3/2)
= 12/2
= 6
