Answer:
(a)
(b)$5955.71
(c)15.02 years
Step-by-step explanation:
For an initial principal P deposited in an account at an annual interest r compounded for a number of period k, the amount in the account after n years is given by the model:

(a)Aunt Ga Ga gave you $5,500 to save for college.
P=$5,500
Annual Interest, r=4%=0.04
Since interest is compounded quarterly, Number of Periods, k=4
Therefore, an exponential function modeling this situation is:

(b)After 2 years, i.e. when n=2

(c)When A(n)=$10000, we have:

Answer:
He spends $107.40.
Step-by-step explanation:
all you have to do is multiply 8.95 by 12
He spends $107.40
Answer:
26
Step-by-step explanation:
We know that the entire angle measures 66 degrees.
Therefore, angle y plus 40 degrees must equal 66.
In an equation:

To solve for y, subtract 40 from both sides:

So, the measure of angle y is 26 degrees.
And we're done!
