The work looks good; but let's check the answer. You are saying, as I read it, that Minah has $360 and Yati has $480. Here is the...

Well, from k/(1- k)= A, you have k= A- Ak so k+ Ak= k(1+ A)= A and k= A/(1+ A) NOT "k= A(1+A)" but you later use A/(1+ A) so that must...

Yes, that is exactly what you want to do. Given the line y= cx+ d (don't forget the "y") a line perpendicular to it at x= x_0 is of the...

You go far away javaman. Not me coz i have a home.

0 x 1 - 2 + 3 + 4^5 - 6 - 7 - 8 + 9 = 1013 (98 - 76) x 5 + 43 x 21 + 0 = 1013

0 x 123 + 4^5 - 6 - 7 - 8 + 9 = 1012 -98/7 + 6 - 5 + 4 - 3 + 2^10 = 1012

A question for you first: How many millilitres in a litre?

Carrying out the indicated integration, we then find: V=\frac{29\pi}{30} If we use the shell method, we find: V=2\pi\int_0^1...

Great thanks so much sir!

this is how i solve the questions. thanks again for all the help.

Yes: V=\pi\int_0^1 \left(\sqrt{x}+1\right)^2-\left(x^2+1\right)^2\,dx I would expand the two squared binomials in the integrand...

So, a and b are 0 and 1? and V= pi * integral: a=0, b=1 * [sqrt. x =1]^2 - [x^2+1]^2 . * dx

Hello, and welcome to FMH! :) Here's a diagram: I would use the washer method. The outer radius is: R=\sqrt{x}-(-1)=\sqrt{x}+1 And...
