Be:
Number of hours: n
<span>The cost of renting a bike for the first hour is $7:
n=1→f(n)=f(1)=$7
</span>He is charged $2.50 for every additional hour of renting the bike:
f(n)=f(n-1)+2.50, for <span>n ≥ 2
</span>
f(1)=7; f(n)=f(n-1)+2.50, for <span>n ≥ 2 (sixth option)
</span>
f(n)=f(1)+2.50(n-1)
f(n)=7+2.50(n-1)
f(n)=7+2.50n-2.50
f(n)=2.50n+4.50 (fifth option)
Answers:
Fifth option: f(n)=2.50n+4.50, and
Sixth option: f(1)=7; f(n)=f(n-1)+2.50, for <span>n ≥ 2</span>
I hope this helps you
10^2=5^2+x^2

x= 5 square root of 3
Well, this is rather lengthy so...
First, you'd do...
1000 * 0.073 = $73.
$73 is for one quarter, so...
A quarter of a year is 1/4 of the year, so you'd need to do... $73 * 4.
= $292.
$292 is for one year.
Now do...
$292 * 30
