Answer: ↓↓↓
Step-by-step explanation:
Part A
131.5 or $131,500 is the starting value of the plane X before it started to depreciate.
Part B (They meant plane Y as in plane Y but plane B as in the second plane, look at the table and Part C)
b (m) = 177,233 (0.024)^m
$177,233 is the starting value of plane Y.
The value depreciates by 2.4% and that is the same as 0.024, except 0.024 is in decimal form.
Part C
b (t) = 177,233 (0.024 x 12)^t
b (t) = 177,233 (0.288)^t
I multiplied 12 by the depreciation because for the whole equation to actually show the depreciation in years I had to solve how much the plane would depreciate in 1 year. So, since 12 months is 1 year, I multiplied 12 by 0.024.
That's it! I hope I'm right because this took a lot of thinking lol
The answer is:
The reason is:
bottom one is a square prism. the volume formula is l x w x h. 9 x 9 x 9
square prism : 729
then the top one is a triangular prism. which is 1/2b x a x a
so 3.5 x 9 x 9
triangular prism: 283.5
then add these 2 numbers
1012.5
You you use the conjugate of sqrt17 - sqrt 2 which is sqrt17 + sqrt2
so the fraction is sqrt17 + sqrt2
------------------
sqrt17 + sqrt2
Given:
Cash price = 1,998
143 per month for 15 months
a) total installment price:
143 x 15 = 2,145
b) the carrying charges
2,145 - 1998 = 147
c) number of months needed to save the money at the monthly rate.
1,998 / 143 = 13.97 or 14 months.
