Answer:
a. f(x)=25+0.02x
b. 0 miles
Explanation:
The charges per week to rent a car =$25
There is an additional cost of $0.02 per mile.
Let the number of miles driven during the week = x
(a)The weekly cost, f o rent a car will be:
(b) If the weekly cost to rent the car was $25
f(x)=25
Substitution into f(x) derived above gives:
If the weekly cost was $25, the car was driven for 0 miles (was not driven at all).
Hi there
The formula of compounded continuously is
A=pe^rt
A future value?
P present value 535
R interest rate 0.06
E constant
T time 10 years
So
A=535×e^(0.06×10)
A=974.83 round your answer to get
A=975
Good luck!

Following the generalized form that you wrote, you know that a negative exponent sends its base to the denominator (or numerator if it's in the denominator already). Or to put it formally as you wrote it, for any nonzero real number a and natural number n, <span>the negative rule of exponents states that </span>

So,

<span>Answer:
The credit card issuer will show APR which is 22.08% and not effective rate of interest.
This is because Effective rate, when calculated with the formula given below will come as 24.67% which is 2.59% more and hence will make customers feel that they are paying more.
r = [ { (1+ i / n) ^ (n) } - 1] * 100
Where i = APR/100
n = number of compounding periods which is 365 in this case as compounding is done daily.
[ { (1+ 0.2208 / 365) ^ (365) }- 1] * 100</span>
