Answer:

-\frac{29}{6}

Step-by-step explanation:

2|x+1/3|<9

2|x+\frac{1}{3} |

Divide both sides by 2 in order to get absolute function alone

|x+\frac{1}{3} |

If |x|=a  then -a<x<a

|x+\frac{1}{3}

-\frac{9}{2}

We need to get x alone

So we subtract 1/3 on both sides

-\frac{9}{2}-\frac{1}{3}

Make the denominator same and simplify the fraction

-\frac{29}{6}

You want to find the volume of the solid obtained by rotating about the x-axis the region under the curve y = x 1 / 6 y=x1/6 fro
Natasha2012 [34]

Answer:

Area = πr², where "r" is some distance "y" and/or the function "(1/6)x"; depending on the situation

Step-by-step explanation:

If I'm picturing this correctly, you'll have conical shape after revolving the function about the x-axis. If you took some generic slice and wanted to find the area of the resulting cross-section, then you would have a circle whose radius is some arbitrary value of the line that matches the slice.

For example:

y = (1/6)x right?

If you took a slice at x = 2, then the radius of the resulting cross-sectional circle would be equal to y = (1/6)•2 =1/3.

From here you just plug it into the area of a circle, πr², to get an area of π/3.

Except with an integral you need to take all the points on the interval, so the radius comes out to be the function itself.

Assuming your integral is in terms of dx, r=y. But in order to integrate in terms of dx you must replace "y" with its function (1/6)x. So ultimately r=(1/6)x and Area = π(1/6)x.

Suppose a term of a geometric sequence is a4 = 121.5 and the common ratio is 3. Write the formula for this sequence in the form
BigorU [14]

Answer:

a_n = 4.5 * 3^{n-1}

Step-by-step explanation:

Given

a_4 = 121.5

r = 3

Required

a_n = a_1 * r^{n -1}

Substitute 4 for n in a_n = a_1 * r^{n -1}

a_4 = a_1 * r^{4 -1}

a_4 = a_1 * r^3

Substitute 121.5 for a_4

121.5 = a_1 * 3^3

121.5 = a_1 * 27

Solve for a1

a_1 = \frac{121.5}{27}

a_1 = 4.5

So, we have:

a_n = a_1 * r^{n -1}

a_n = 4.5 * 3^{n-1}
