Answer:
C
Step-by-step explanation:
This is simple application of the rule of 72.
The rule of 72 determines how long an investment will take to double given fixed interest rate. We divide 72 by annual rate of return and get the estimate of number of years it will take for investment to double.
Thus, here, rate of interest is 5%, so we divide 72/5 and get our rough estimate.
72/5 = 14.4 Years
That's about 14 years, answer choice C
Answer:
It's close between Y and Z, but I'd go with Z
Step-by-step explanation:

Well the square root of a number is a number times its self equaling the number you're getting the square root of. For example:
<span>√ 25
</span>
To get sqrt of 25 we need to find a number times its self that equals 25. Lets try 8.
8 x 8 = 64
Well thats much too high, We'll try a lower number.
4 x 4 = 16
Just a little higher.
5 x 5 = 25
Since 5 times itself equals 25 that makes it the sqrt.
So, the √ 25 is 5.
y= mx+b
(16, -7) = (x,y)
2(16) - 3y = 12
32 - 3y = 12
32 - 12 = 3y
20/3 = y
6.6 = y
2x-3(-7) = 12
2x+21 = 12
2x = 12 - 21
x = -9/2
Insert the values into y = mx + b
solve for m and then solve for b
