Best ResponseYou've already chosen the best response.1did you get the 'sketch the region' one?

Algebraic!

Best ResponseYou've already chosen the best response.1basically just asking you to pick which of those areas is bounded by y=5, x=4 and the function...

Algebraic!

Best ResponseYou've already chosen the best response.1the first choice is bounded by y=10, x=4 and the function... the second choice is bounded by y=10, x=0, x=4 and the function...

Best ResponseYou've already chosen the best response.0I know the answer for the first picture already, not sure about the 2nd one @Algebraic!

Best ResponseYou've already chosen the best response.0For the first picture, i think it is the last one for the 2nd picture, i am thinking either 1st or 4th one , what do u think ?

Algebraic!

Best ResponseYou've already chosen the best response.1naw, the last picture is bounded by x=0 y=0 and the function...

Best ResponseYou've already chosen the best response.0so for the first picture, u also think is the last one?

Best ResponseYou've already chosen the best response.0for my function, x is not 0 u mean?

Best ResponseYou've already chosen the best response.0dont u need to integrate the area function to volume , and then something to do with the height..?

Algebraic!

Best ResponseYou've already chosen the best response.1so... is that the region described in your problem statement??

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1really? your problem statement makes no mention of x=0 or y=0 ...

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1it does mention y=5 however...

lovekblue

Best ResponseYou've already chosen the best response.0well, but it says rotate about y= 10, and y= 5

lovekblue

Best ResponseYou've already chosen the best response.0then u can kinda know there is a hole in between

lovekblue

Best ResponseYou've already chosen the best response.0umm..wait..so which picture do you think it is for the first set of picture? i thought we have the same answer

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1the region is bounded by x=4 y=5 and y=5e^x

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1like I said trace the boundary of the regions you have been given to find which one works with that description..

Algebraic!

Best ResponseYou've already chosen the best response.1there's no point in guessing here... even though this is multiple guess

lovekblue

Best ResponseYou've already chosen the best response.0i still think is the last one..

lovekblue

Best ResponseYou've already chosen the best response.0that's why i want to know which one u think it is

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1why is it the last one..

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1are you talking about the first part or the second part?

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1because if you do the first part correctly, the answer to the second part should be obvious

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0so do you agree that it is either the bottom left or bottom right picture is correct due to the fact that given y=5

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1then why are you saying it's the last region?

lovekblue

Best ResponseYou've already chosen the best response.0why is it not the last picture ..lol dw:1352778179844:dw

Best ResponseYou've already chosen the best response.1did you see the sketches where I traced the bounding functions??

lovekblue

Best ResponseYou've already chosen the best response.0the curve is y= 5e^x , y =5 , x=4

Best ResponseYou've already chosen the best response.0are you trying to say that radius doesnt bound to x=0?

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0which it does indeed make sense when i look in the 2nd part

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1I'd focus on the first part, if I were you..

Algebraic!

Best ResponseYou've already chosen the best response.1picking which region is bounded by y=5, x=4 and y= 5e^x

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0i'm not sure what u mean by bounded..do you mean by starting from there？

Algebraic!

Best ResponseYou've already chosen the best response.1trace the boundary of each region

Algebraic!

Best ResponseYou've already chosen the best response.1like I did... for the last region pictured in your choices...

lovekblue

Best ResponseYou've already chosen the best response.0if i do what u did, then the answer will be the bottom left

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0but my question with that picture is.. don't u need to do 5 5e^t in order to get tht area?

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1you'll be using washers probably, since you haven't learned about shells yet (I assume)...

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1so the inner radius is 5 and the outer radius is 105e^x

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0yea i didnt yet.. i didnt even learn these stuff much when my assignment is due 2 days after..

lovekblue

lovekblue

Best ResponseYou've already chosen the best response.0can i ask what does "region " mean..

Algebraic!

Best ResponseYou've already chosen the best response.1the red areas in the first part.

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0yea..what does that red area mean

lovekblue

Best ResponseYou've already chosen the best response.0is it like the path of rotation or something?

Algebraic!

Best ResponseYou've already chosen the best response.1it's the thing you're sweeping around the specified axis in order to generate a solid

Best ResponseYou've already chosen the best response.1take that region as an example... it's a rectangle...

Algebraic!

Best ResponseYou've already chosen the best response.1rotate about the x axis and you sweep out a cylinder..

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0so it's kinda you are sweeping that region, and that sweeping motion generate the solid figure?

Algebraic!

Best ResponseYou've already chosen the best response.1the second multiple choice question? or a new question?

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0it's the same question. but it asks to find the volume

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0cuz finding the volume is actually the first part..but the graphing part seems easier so i skipped to that first ..

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1sure... we are using the washers in the sketch (and in the last choice to the second question)

Algebraic!

Best ResponseYou've already chosen the best response.1inner radius is 5, outer radius is 10  5e^x

Algebraic!

Best ResponseYou've already chosen the best response.1area of a washer will be pi( (10  5e^x)^2  5^2 )

lovekblue
 2 years ago
Best ResponseYou've already chosen the best response.0yea..that's all i have too.. not sure how to integrate that..

Algebraic!
 2 years ago
Best ResponseYou've already chosen the best response.1\[\pi \int\limits_{ }^{} (105e^{x})^2  5^2 dx\]

Algebraic!

lovekblue

Best ResponseYou've already chosen the best response.0i got pi ((300+10 e^4  25/2 e^8) (1025/2))
