Since you pay 9.5% extra per year, that is equal to 109.5% of last year, or 1.095 in decimal form
The base equation:
<span>y=k<span>ax</span></span>
Sub in your values:
<span>y=10000×<span>1.0953</span></span>
Simply solve for that
<span>y=10000×<span>1.0953</span></span><span>y=10000×1.312932375</span><span>y=13129.3</span>
So you would owe <span>$13129.30</span>, after 3 years, given that you do not deposit any money over the course of that time
Answer: Choice D) 5.9
================================================================
We'll be using the tangent rule two times to find the lengths of BD and BC, which we'll subtract to compute the length of CD. Make sure your calculator is in degree mode.
---------
Focus on triangle ABC for now (ignore point D)
For reference angle A:
AB = adjacent = 85
BC = opposite = unknown = x
tan(angle) = opposite/adjacent
tan(A) = BC/AB
tan(28) = x/85
x = 85*tan(28)
x = 45.1953
---------
Now focus on triangle ABD (ignore point C)
For reference angle A:
AB = adjacent = 85
BD = opposite = unknown = y
tan(angle) = opposite/adjacent
tan(A) = BD/AB
tan(31) = y/85
y = 85*tan(31)
y = 51.0732
---------
Subtract x and y (large-small)
y-x = 51.0731-45.1953 = 5.8778
this rounds to 5.9
