The original value of a car is $18,000, and it depreciates (loses value) by 15% each year. what is the value of the car after three years?

Answers

Answer 1
Answer:

If the original value of a car is $18,000, and it loses value by 15% each year, then you can calculate the new value of the car after n years using following formula:

P=\$18,000\cdot (1-0.15)^n.  

When n=3, then

P=\$18,000\cdot (1-0.15)^3=\$18,000\cdot 0.85^3=\$11,054.25.  

Answer: the value of the car after 3 years is $11,054.25.
Answer 2
Answer:

I think the answer would be 11,054.25$

Y is 15 and x is 14 mark me as brainless
x = 13, assuming they are the same length.
Using the pythagorean Theorem formula (a^2 + b^2 + c^2) Plug in A and B (13, and 13).
(13)^2 + (13)^2 = c^2
13 • 13 + 13 • 13 = c^2
169 + 169 = c^2
v/338 = v/c^2 (square root them both)
Then you can have your answer for y, hope this helps

One side of a regular octagon is 4 inches long. What is the length of another side of the octagon?32 inches
8 inches
4 inches
can't be determined

Answers

The length of the other side is 4 inches and total length is 32 inches , Option C is the answer.

What is a Regular Octagon ?

A regular octagon is a polygon with eight sides and all the sides are equal.

It is given that side of a regular octagon is 4 inches

The length of the other side will also be 4 inches

The total length or the perimeter of the regular octagon is

4*8

= 32 inches

Therefore the length of the other side is 4 inches and total length is 32 inches , Option C is the answer.

A regular octagaon has 8 equal sides 

so it only makes sense to say that the other side of an octagon would be 4 inches too!

But  if you want to know the total length,  multiply 8 x 4 = 32 inches!  
BUT THIS IS ONLY IF ITS A REGULAR OCTAGON 

otherwise it can't be really determined since I don't know its symmetry or the angles!!
