Analyze perfect cubes:
1^3 = 1
2^3 = 8
3^3 = 27
Since 12 is between 8 and 27, cube root of 12 is between 2 and 3.
You also know it is much closer to 2, since 12 is much closer to 8.
A good guess would be 2.25
(2.25)^3 = 11.39
This is close but slightly less than 12.
When you use your calculator you should get 2.2894.
<span>At the end of a full year (360 days), the note will have a total value of (15000 * 1.06), or $15,900. This gives an interest amount of $900. Dividing this by 12 months gives the per-month rate. (900 / 12) = $75, which would be the amount of interest accrued by December 31 on this note.</span>
Lol I’m learning the same exact thing in math . Your equation is going to be .10d+.05(D+10)=1.70
.10d + .05D + 0.5 = 1.70
.15D +0.5 = 1.70
0.5 -0.5
.15D=1.20
D= 8
n=18
Hopefully this is right
Hey! The answers are B & C
