Find the volume of the solid of revolution generated by revolving the region bounded by y = 2x^2, y = 0, and x = 2 about the x-a

Irina18 [472]

Answer:

$128 \pi/5 units^3$

Step-by-step explanation:

The volume of the solid revolution is expressed as;

$V = \int\limits^2_0 {\pi y^2} \, dx$

Given y = 2x²

y² = (2x²)²

y² = 4x⁴

Substitute into the formula

$V = \int\limits^2_0 {4\pi x^4} \, dx\\V =4\pi \int\limits^2_0 { x^4} \, dx\\V = 4 \pi [\frac{x^5}{5} ]\\$

Substituting the limits

$V = 4 \pi ([\frac{2^5}{5}] - [\frac{0^5}{5}])\\V = 4 \pi ([\frac{32}{5}] - 0)\\V = 128 \pi/5 units^3$

Hence the volume of the solid is $128 \pi/5 units^3$

∠5 is a supplement of ∠6, and m∠5=78°. Find m∠6.

vekshin1

Answer:

$102^\circ$

Step-by-step explanation:

Given that:

$\angle 5$ is a supplement of $\angle 6$ .

m $\angle 5$ = 78°

To find:

m $\angle 6$ = ?

Solution:

First of all, let us learn about the concept of an angle being a supplement of the other angle.

$\angle B$ is known as supplement of $\angle A$ , if sum of the two angles is equal to 180°.

$i.e. \angle A +\angle B=180^\circ$ .

For example, angle made on one side by a line intersecting the other line are supplement of each other.

Here, we are given that $\angle 5$ is a supplement of $\angle 6$ .

In other words:

$\angle 5+\angle 6=180^\circ$

Putting value of $\angle 5$ :

$\Rightarrow 78^\circ+\angle 6=180^\circ\\\Rightarrow \angle 6 =180^\circ-78^\circ\\\Rightarrow \bold{\angle 6 =102^\circ\\}$

So, the answer is: $102^\circ$
