$3,300 is invested in an account earning 7:7% interest (APR), compounded monthly. Write a function showing the value of the account after t years,
where the annual growth rate can be found from a constant in the function.
Round all coefficients in the function to four decimal places. Also, determine
the percentage of growth per year (APY), to the nearest hundredth of a
percent.

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

answer is  

minor arc – sw

major arc – stu

semicircle – wst

i got it down chief.

this is a geometric sequence with common ratio r

r = = = = 3

(a)

to obtain a term in the sequence multiply the previous term by 3

= 3 ← recursive rule

(b)

the n th term of a geometric sequence is

=

where is the first term and r the common ratio

= 6 × ← explicit rule

i believe the answer is b
