Answer:
4
Step-by-step explanation:
To compute a log that doesn't have a base of 10 you use the following formula
Log(number)/Log(base)
We can use this formula to compute the numbers with no variables
Log₃18= Log(18)/log(3) which gives us around 2.63
We can then compute the first part of the right side 2*log₃6 which can be rewritten as 2*(log(6)/log(3)) which gets us around 3.26
After computing this we can rewrite it all as 2.63=3.26-(.5*log₃x)
This is pretty easy to solve from here and we start by subtracting 3.26 from both sides which gives up
-.63=.5*log₃x
Dividing both sides by negative one half (or .5) gives us
1.26=log₃x
You then can use a special rule to rewrite this equation
3^1.26=x
This gives us 3.99 which is pretty much 4
Answer:
42 years, 9 months
Step-by-step explanation:
Using the compound interest formula Accrued Amount = P (1 + r/n)^(nt)
where Accrued amount (A) which is quadruple the initial deposit
A = 4 x 500 = $2000
P = principal; $500
r = 3.25% = 0.0325
t = number of years
n = number of times interest is compounded = 12 for monthly
Therefore
2000 = 500 (1 + 0.0325/12)^(12t)
Therefore
(1.002708)^12t = 2000/500
(1.002708)^12t = 4
finding the log of both sides
12t x log 1.002708 = log 4
12t x 0.001174 = 0.6021
12t = 0.6021/0.001174
12t = 512.83
t = 512.83/12
t = 42.7
which is estimated as 42 years, (0.7 x 12 = 9) months
hence it takes about 43 years to quadruple the deposit

The answer is B.spin a spinner with 4 equal sections two times
Step-by-step explanation:
63 is composite because its factors are 1,3,7,9,21, and 63 itself.
