Cross multiply
5(r+5) = 9(r-9)
5r + 25 = 9r - 81
25 = 4r - 81
4r = 106, r = 106/4 = 53/2
The answer is r = 53/2

Answer:

The common ratio r = 2.

Step-by-step explanation:

Now s2 = a1r and s4 = a1r^3  where a1 = first term and r = common ratio so

s4 / s2 = a1r^3  / a1r = r^2 = 32/8

r^2 = 4

r = 2.

Calculate the simple interest on a loan of $3500 for a period of 6 months at a yearly rate of 5%. (10 POINTS!!)​
ser-zykov [4K]

Answer:

$3,799.20

Step-by-step explanation:

We presume your formula is intended to be ...

M = Pm(1 + m)^(na)/((1 + m)^(na) - 1)

where M is the monthly payment, m is the monthly interest rate, n is 12, and a is the number of years.

This formula gives written below:

M = 3500·(.08/12)·(1 + (.08/12))^(12·2)/((1 + (.08/12))^(12·2) -1) ≈ 158.30

The total payback will be the sum of 24 of these payments is written below;

payback = 24×$158.30 = $3,799.20
