First seat = 9
second seat = 9 + 6 = 15
third seat = 15 + 6 = 21
fourth seat = 21 + 6 = 27
fifth seat = 27 + 6 = 33
sixth seat = 33 + 6 = 39
Given that the time taken to get to campus is inversely proportional to driving rate, let the time be t and rate be r, thus the function will be written as:'
t=k/r
where
k is the constant of proportionality given by:
k=tr
when r=20 mph, t=1.25 hrs
thus
k=20×1.25
k=25 miles
thus the formula is:
t=25/r
when r=55 mph, the value of t will be:
t=25/55
t=5/11 hours
1. f(x) = 1
2. f(x) = x
3. f(x) = 5 - x
4. f(x) = 3
First, subtract the two values:
16 - 15.4 = 0.6
Now divide this to the actual area:
0.6 / 15.4 = 0.038961039
Multiply by 100:
0.038961039 * 100 = 3.8961039
So the percent error is approximately 3.9%
