a^x  - if a is less than 1, it's a decreasing function

eg is a =0.53, then it's decreasing, and at 47% per year (1-0.53 = 0.47, convert to percentage)

anonymous · Answer

I did, I mean is it right?

agent0smith · Answer

"anything above ******1****** is exponential growth" NOT 0.99, 0.999 is greater than 0.99 but is still decay.

Your percentage rate is not 63%. See above post.

anonymous · Answer

My bad, 0.63/100 ?

anonymous · Answer

No... yes.. maybe?

agent0smith · Answer

anonymous · Answer

agent0smith · Answer

eg is 0.53^x,

 it's decreasing at 47% per year (1-0.53 = 0.47, convert to percentage) <<<<look at the numbers involved

anonymous · Answer

agent0smith · Answer

That's what the medal tells you :P

anonymous · Answer

;) staph it

agent0smith · Answer

Assuming numbers for B are correct, too tired to check that

anonymous · Answer

yeaa thats the only reason i got on to check teheh, to see if its possible to have a -24.51%

anonymous · Answer

?

agent0smith · Answer

You did part b... not right. You're finding percentage decrease. It decreased 2451. Divide that by what it started at, 4300, then multiply by 100%

anonymous · Answer

so -57

agent0smith · Answer

It's asking for greatest % change isn't it...

anonymous · Answer

I'm not following, what am I suppose to be looking for?

agent0smith · Answer

Percent change that you found above for both. Which is bigger.

anonymous · Answer

product a ofc, its positive

agent0smith · Answer

They're both decreasing. Which decreases more.

agent0smith · Answer

It doesn't decrease at -57% per year. It decreases at 57% per year.

anonymous · Answer

oh lol

anonymous · Answer

so that was the only mistake? can i finally submit this D:

agent0smith · Answer

yes, since decreasing at negative 57% means increasing at 57% :P

anonymous · Answer

So basically take the negative sign out, Product B decreases at a 57% every year whereas product A decreases at a 37% rate. Product A recorded the highest price every year. ?

agent0smith · Answer

"Product A recorded the highest price every year." i don't see where it asked for that...

anonymous · Answer

so i should remove it? " Which product recorded a greater percentage change in price over the previous year" what should i answer for this part?

agent0smith · Answer

Which product recorded a greater percentage change in price over the previous year - product B did

anonymous · Answer

ohh ok ty
