Answer:
Hello!!
For question twelve, is an identity.
For question thirteen, has no solution.
Hope this helps!!
The balance in the account after 13 years is $8233.79.
<h3>Compound interest: Calculating balance in an account</h3>
From the question, we are to use the compound interest formula to compute the balance in the account
From the compound interest formula, we have that
A = P(1 + r/n)^nt
Where A is the amount
P is the principal
r is the interest rate
n is the number of times compounded per year
and t is the time.
From the given information,
P = $7000
r = 3.3%= 0.033
n = 1
t = 13
Putting the parameters into the formula
A = P(1 + r/n)^nt
A = 7000(1 + 0.033/1)^(1×5)
A = 7000(1 + 0.033)^5
A = $8233.79
Hence, the balance is $8233.79

It’s C because if you type it In this is what it comes out as
The cost to park for the first day is = $15
Cost to park for each subsequent day = $ 10
Let the number of days be represented by = n
Let the parking cost be denoted by function = p(n)
So, out of all the given options,
Option 4th is correct.
p(1) =15; p(n)=p(n-1) +10 for n≥2
Explanation:
Put n=2
=
Hence, day 1 fee is $15 and day 2 fee is $10 so total is = $25
Option 6th is correct.
p(n) = 10n+5
Explanation:
Total cost is represented as =
=
=
=
