I believe it is 60. 21/0.35 should equal 60.
Answer:
2(x+1)²-3
Step-by-step explanation:
Using the vertex formula we can write the follwoing equation
y=a(x+1)²-3
We need to solve for a
we know that when x= 2 y = 15
So we can write
15=a(2+1)²-3
15=9a-3
18=9a
a=2
Which means our final equation is
2(x+1)²-3
in standard form (just in case)
2x²+4x-1

Answer:
$3644675.9
Step-by-step explanation:
The initial investment is $100000. The interest rate is 12%.
We are asked to determine the final amount the investment will become after 30 years if the interest is compounded weekly.
The weekly interest rate is 
%.
Assuming 1 year equivalent to 52 weeks.
Hence, using the formula of compound interest the final sum will be
= $3644675.9 (Approximate)
You've given us a single term of an arithmetic series. So far, there are an infinite number of different series that it could be a member of. ... In fact, ANY function f (n) for which f (7) = 54 produces a suitable series for whole-number values of 'n'. Here are a few: ... T(n) = n + 47. ... T (n) = 8n - 2. ... T (n) = -10n + 124 .
