Answer:
The height of the platform is 65 ft
Step-by-step explanation:
Let
t -----> the time in seconds after the launch of the fireworks from a platform
h(t) ----> the height of a firework in feet
we have

we know that
The height of the platform is when the value of t is equal to zero (y-intercept)
For t=0


therefore
The height of the platform is 65 ft
5 ft is 5 times 12 inches which is 60 inches
So 54 to 60.
In ratios a to b is a:b
so 54 to 60 is 54:60
and we can simplify that and we get
54:60
27:30
9:10
So the ratio of 54 in to 5 ft is 9 inches to 10 inches. :)
