Answer:
A
Step-by-step explanation:
This is a quadratic equation with
a = -16
b = 45
c = 15
The highest point is reached when [tex]x=-\frac{b}{2a}[/tex]
What is the x value given a,b,c values? Lets find it.
[tex]x=-\frac{45}{2(-16)}\\x=-\frac{45}{-32}\\x=\frac{45}{32}\\x=1.41[/tex]
So, the highest point occurs at x = 1.41
Here the independent variable is t, time. So we can say:
At t = 1.41 seconds, the clown reached max height.
From the choices, we select A) 1.4 seconds
