Let the region R be the area enclosed by the function f(x)=ln(x) and g(x)= 1/2x-2. Find the volume of the solid generated when t

Neporo4naja [7]

Answer:

$V=61.66$

Step-by-step explanation:

This problem can be solved by using the expression for the Volume of a solid with the washer method

$V=\pi \int \limit_a^b[R(x)^2-r(x)^2]dx$

where R and r are the functions f and g respectively (f for the upper bound of the region and r for the lower bound).

Before we have to compute the limits of the integral. We can do that by taking f=g, that is

$f(x)=g(x)\\ln(x)=\frac{1}{2}x-2$

there are two point of intersection (that have been calculated with a software program as Wolfram alpha, because there is no way to solve analiticaly)

x1=0.14

x2=8.21

and because the revolution is around y=-5 we have

$R=ln(x)-(-5)\\r=\frac{1}{2}x-2-(-5)\\$

and by replacing in the integral we have

$V=\pi \int \limit_{x1}^{x2}[(lnx+5)^2-(\frac{1}{2}x+3)^2]dx\\$

$V=\pi [28x+\frac{1}{x}+xln^2x-12xlnx-6lnx]$

and by evaluating in the limits we have

$V=61.66$

Hope this helps

Solve for the following 6(16x+3)-2/3(9-12x)+25=0

lutik1710 [3]

First expand the parentheses:-

96x + 18 - 6 + 8x + 25 = 0

104x = -18 + 6 - 25 = -37

x = -37 / 104 = -0.3558

38. The volume of a cylinder is 97 ft3. If the dimensions are doubled, what will be the new volume?

asambeis [7]

Volume is cubed. If the dimensions are doubled, cube the scale factor:

2^3 = 8

The volume will increase by a scale of 8.

The new volume would be 97 x 8 = 776 ft^3

Write a quadratic function whose graph has a vertex of (3,2) and passes through the point (4,7). f(x)=

agasfer [191]

Answer:

y=5(x-3)^2+2

Step-by-step explanation:

You plug the point into f(x)=a(x-3)^2+2... that already has already been solved for the vertex that you want. Then you swap it out for the solution you have solved for.
