Answer:
3.1 x 10^-2
Step-by-step explanation:
Let me show u one in detail.
First we have to find the common ratio. We do this by dividing the second term by the first term.
ur first problem...
12/3 = 4...so the common ratio is 4
now we use the formula
an = a1 * r^(n-1)
n = term u want to find = 15
a1 = first term = 3
r = common ratio = 4
now we sub
a15 = 3 * 4^(15 - 1)
a15 = 3 * 4^14
a15 = 3 * 268435456
a15 = 805,306,368 <== ur 15th term
thats all there is to it...and, of course, u can always look on the internet for a geometric sequence calculator...to check urself...lol
Answer : x^2 - 4x^2 - 2x^2 + 3
Answer:
$4,500
Step-by-step explanation:
You would divide $15,000 by 10 to get 10% then to get 30%, which is how much it is after 5 years, you would multiply by 3 to $4500 which is the answer
First, find a common denominator: 40
then, convert the fractions: 30/40 and 32/40
between those two, it would be 31/40
answer: 31/40
