Answer:
9 notebooks=36 or 12 pens=24+ 4 notebooks=12 in total 36
Step-by-step explanation:
first way: 9×4=36
second way: 12×2=24
3×4=12
24+12=36
Answer:occurring continuously over a period of time
Step-by-step explanation:
The answer is a..........,
Multiply both sides:
(2x + 2)(x + 3)
= 2x^2 + 6x + 2x + 6
= 2x^2 + 8x + 6
<h2>Answer: (1) 2x^2 + 8x + 6</h2>
Answer:
Step-by-step explanation:
Given that the region bounded by x axis, x=e^2 and y = lnx be rotated about x axis
The limits of x are ![1](https://tex.z-dn.net/?f=1%3Cx%3Ce%5E2)
Volume generated = ![\int\limits^{e^2} _{1} \pi {y^2} \, dx \\\\=\int\limits^{e^2} _{1} \pi {(lnx)^2} \, dx \\\pi[x (lnx)^2 -\int\limits^{e^2} _{1} x(2lnx)dx]\\=2(e^1-1)\pi](https://tex.z-dn.net/?f=%5Cint%5Climits%5E%7Be%5E2%7D%20_%7B1%7D%20%20%5Cpi%20%7By%5E2%7D%20%5C%2C%20dx%20%5C%5C%5C%5C%3D%5Cint%5Climits%5E%7Be%5E2%7D%20_%7B1%7D%20%20%5Cpi%20%7B%28lnx%29%5E2%7D%20%5C%2C%20dx%20%5C%5C%5Cpi%5Bx%20%28lnx%29%5E2%20-%5Cint%5Climits%5E%7Be%5E2%7D%20_%7B1%7D%20x%282lnx%29dx%5D%5C%5C%3D2%28e%5E1-1%29%5Cpi)
