Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. y=1/x^5, y=0,

igomit [66]

If you wanted to rotate f(x) around the y axis from x=a to x=b then the volume would be
$\pi \int\limits^a_b {(f(x))^2)} \, dx$

that would be

$\pi \int\limits^8_1 {(\frac{1}{x^5})^2} \, dx$
$\pi \int\limits^8_1 {\frac{1}{x^{10}}} \, dx$
1/x^10=x^-10
integrate
-1/(9x^9)
so
$\pi \int\limits^8_1 {\frac{1}{x^{10}}} \, dx$ =
$\pi [\frac{-1}{9x^{9}}]^8_1=\pi (\frac{-1}{9(8^{9})}-\frac{-1}{9(1^{9})})=$
$\pi (\frac{-1}{9(8^{9})}+\frac{1}{9(1^{9})})=\pi (\frac{-1}{9(8^{9})}+\frac{1}{9})=$
$\pi (\frac{-1}{9(8^{9})}+\frac{8^9}{9(8^9)})=\pi (\frac{8^9-1}{9(8^{9})})=$
$(\frac{\pi8^9-\pi}{9(8^{9})})=\frac{134217727 \pi}{1207959552}$
that's the volume of the solid

I need to find the missing angle measures.

scoray [572]

Answer:

step 1. b = 102° (vertical angles)

step 2. one complete revolution equals 360°

step 3. a + b + c + 102 = 360

step 4. a + 102 + c + 102 = 360

step 5. a + c = 156°

step 6. 2a = 156 (vertical angles are equal)

step 7. a = 78°, c = 78°.

PLZ ANSWER !!!! BRAINLIEST!!!

Answer: 238,400,000 is predicted to wear corrective lenses.

Step-by-step explanation:

We can use a ratio table to solve this problem.

So far, with the data given, we can construct a ratio table that looks like this:

Population: 1000, 320,000,000

Cor. Lenses: 745, ?

We know 745 people out of 1000 wear corrective lenses, yet how many out of 320 million people wear them?

To solve this, we need to figure out how many times 1000 is away from 320 million. We can find this out by dividing 320,000,000 by 1000. This results in 320,000. This meant that 1000 was multiplied 320,000 times to get to 320 million. However, what we do to one side of the ratio table, we must do it to the other.

This means we have to multiply 745 by 320,000. This results in 238,400,000. Out of 320 million Americans, 238.4 million wear corrective lenses.

Answer:

39.7

Step-by-step explanation:

first must calculate the length of AB and BC

AB = 16.43

CB= 12.216

then perimeter : Perimeter of a triangle = sum of all three sides

$16.43 + 11 + 12.216 = 39.646 = 39.7$
