A rectangle has a height of 3 cm and width of 5cm. A proportional rectangle has a height of 12cm. What would be the width?

Schach [20]

The ratio will be same

Let width be x

$\\ \sf\longmapsto \dfrac{3}{5}=\dfrac{12}{x}$

$\\ \sf\longmapsto 3x=5(12)$

$\\ \sf\longmapsto 3x=60$

$\\ \sf\longmapsto x=\dfrac{60}{3}$

$\\ \sf\longmapsto x=20cm$

Express each expression as a single logarithm.

andreev551 [17]

Answer:

1. 6

2. 23

Step-by-step explanation:

logx+1 ( x^2 + 2x + 1)^3

= 3logx+1 ( x^2 + 2x + 1)

= 3 logx+1 (x + 1)^2

= 6 logx+1 (x + 1) Now the logx+1 x+1 = 1 so

The answer is 6.

log11 11^23

= 23 log11 11

As in question 1 log11 11 = 1

So the answer is 23.

Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.

amm1812

Answer:

$V = \frac{8\pi}{3}$

Step-by-step explanation:

For this case we are interested on the region shaded on the figure attached.

And we can find the volume with the method of rings.

The area on this case is given by:

$A(x) = \pi [f(x)]^2 = \pi r^2 = \pi [3x]^2 = 9\pi x^2$

And the volume is given by the following formula:

$V= \int_{a}^b A(x) dx$

For our case our limits are x=0 and x=2 so we have this:

$V = \pi \int_{0}^{2} x^2 dx$

And if we solve the integral we got this:

$V= \pi [\frac{x^3}{3}]\Big|_0^{2}$

And after evaluate we got this:

$V=\pi [(\frac{8}{3} )-(\frac{0}{3} )]$

$V = \frac{8\pi}{3}$
