Answer 2

All help is appreciated

Answer 3

wow... looks like a quiz

Answer 4

You should graph the first one and then ask a more specific question. What don't you understand?

Answer 5

how to do it, cuz its a brand new concept

Answer 6

Alright, well here is a graph: http://www.wolframalpha.com/input/?i=plot+y%3Dsinxcos%5E2x%2C+y+%3D+2xcos%28x%5E2%29%2C+y+%3D+4-4x+from+0+to+2

Answer 7

OMG THANYOU FOR THE GRAPH SO HELPFUL

Answer 8

Unfortunately, there are two regions bounded by those three curves. Which one is wanted?

Answer 9

the upper right quadrant

Answer 11

help I have like 10 minutes

Answer 12

this looks evil problem

Answer 13

haha k

Answer 14

i suggest u skip this problem and work other problems first

Answer 15

u can get back to this after finishing everything

Answer 16

I have, these are the last 2

Answer 17

5 min

Answer 18

I repeat, there are TWO regions in Quadrant I bounded by the three curves. However, only the one next to the Origin in in the answer choices.

You will need the points of intersection.

x = 0
x = ???
x = ????

These will be your integration limits.

Fortunately, all three functions have rather simple antiderivatives.

Answer 19

Better start finding points of intersection.

Answer 20

could u just tell me the solution so I can really understand it after the quiz plzz, I just dont have the time lol

Answer 21

well for the 2nd equation you need to look at

\[\int\limits_{0}^{h} (x^2 - 4x + 4)dx = \int\limits_{h}^{2}(x^2 - 4x + 4)dx\]

then solve for h

Answer 22

k

Answer 23

"2"?

You can just eyeball it. It looks like it's about 1/3ish. That narrows it down to 2 choices.

Answer 24

but that will give a horrible cubic to solve

Answer 25

h=2-2^2/3

Answer 26

2 min

Answer 27

well you need a decimal answer

Answer 28

come on plz, I want to learn it but I only have 2 min left

Answer 29

well I got the 2nd choice as an answer to 8

Answer 30

is 8 b?

Answer 31

1 min

Answer 32

I need 7 plzz, your best guess!

Answer 33

You cannot learn this in 10 minutes. You squandered 8 of them when you didn't find the points of intersection.

Oh, I see. I was doing #7. '2' is good for #8

Answer 34

No need to guess.

x = 0
x = 0.6927512685228328
x = 0.9281129265516105

Integration is all that is left.

Answer 35

so is7 b

Answer 36

You're not really trying. The eyeball method already told us it is C or E

Answer 37
