Question

Help please? Will give medal and fan. (:
Question is in the comment section. :3

Answer 1

Use the graph from Question 1 to identify where the volumes are equal. Confirm this value by writing and solving an equation that describes the difference between the volumes of the candle types.

Answer 2

I'll give the volumes for each graph as well if it helps. c:
Volume for brick candle: x^3 - x^2
Volume for Egyptian candle: 1/3x^2 + 7x

Answer 3

idk sorry i cant help you :-(

Answer 4

Awe, it's okay. I've just been working on this for quite a while and I'm getting frustrated. >.<
Makes me feel stupid. .-.

Answer 5

@TheSmartOne can u help her out?

Answer 6

@StudyGurl14 Any idea about this? I really need help. :(

Answer 7

Okay graph it again at desmos. Graph BOTH equations at the same time. Look for the intersection and click it. A tag will show up with the coordinate and the x-value is the answer

Answer 8

Thank you! I'll write a testimonial for you, too. (:
I graphed both equations. I've attached a file to show you where they intersect. They also intersect at (0,0).
However, how do I do the second part of the question? "Confirm this value by writing and solving an equation that describes the difference between the volumes of the candle types. "

Answer 9

Ignore the (0,0) point. The other point illustrates the answer. You're welcome. :)

Answer 10

Thank you for the testimony, as well. :)

Answer 11

Hmm...for the second part I'm not exactly sure what they're looking for/asking.

Answer 12

Difference of volumes: indicating subtracting one equation from the other
However, I'm not sure how this can confirm the value...

Answer 13

So, if I subtracted an equation from another, would that leave me with the x coordinate? Rather confused by this question. .-.

Answer 14

Same here...I'm sorry I cannot be of more help. :(
