So you're combining equations correct?
3.5 feet converted to inches is 42 inches. 42"-14"=28"
28" divided by 2 sides is 28/2 = 14" on either side if the poster remaining
Answer:
Equation would be y=0x+2.
Step-by-step explanation:
b = 2
m = 0
using the formula,
y=mx+b
or, y = 0x+2
or, y = 0+2
so, y = 2
It will take the roller coaster 171.652 seconds to pass over the hill and reach ground level
<h3>How to determine the time to hit the ground?</h3>
The function is given as:
h = –.025t^2 + 4t + 50
Set h = 0.
So, we have:
–.025t^2 + 4t + 50 = 0
Using a graphing calculator, we have:
t = -11.652 and t = 171.652
Time cannot be negative.
So, we have:
t = 171.652
Hence, it will take the roller coaster 171.652 seconds to pass over the hill and reach ground level
