well first I won't give you the answer, but I will tell you how to get it. Now You need to find 7% of 400 ( 400 x .07= ??) Now take that answer and multiply you answer by 6. And last add that answer to 400 and that is what the painting will be worth. Hope that this helps good luck

I am 7th going to 8th and i can even answer it!
Find 7% of 400 which is 28.
Multiply 28 by 6 which is 168.
Finally add 168 and 400.
The answer is 568.
Hope this help! And u sure you're 11th grade? U dont seem like it...

I don't think it can be $568.....if it's value increases 7% each year, then the $428 would be on top of the 7%. Has to be more than that. Accumulated interest vs. fixed interest.

Wellllll.... if the painting increases in value by 7% of it's ORIGINAL value, then the answer is:
$568
If it increases in value by 7% of it's CURRENT value each year the answer is:
$600.29

Assuming it increases by 7% of its PRECEDING value the answer is 400{(1.07)^6} = $600.29 - the ones who said 520 or whatever are wrong

Multiply the 400 by .07, then multiply that answer by .07, multiply each answer by .07 unitl you have done that 6 times. That will give you your answer.

amplitude is a million/2 (the wave oscilates between 3.5 and four.5 so please examine the definition of amplitute, i could be incorrect) era is 3pi because of fact there is area of two/3 undergo in techniques cos x has a era of 2pi cos Ax have a era of 2pi for Ax so x could have a era of 2pi/A. in different words, if A is larger than a million, the wave oscillates swifter (shorter era), and if A is below a million, the era gets larger.

you have to keep adding the interest each year....it continues building...so...
1st year it is worth 428.00
2nd year it is worth 457.96
3rd year it is worth 490.02
4th year it is worth 524.32
5th year it is worth 561.02
6th year it is worth 600.29
