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

Maslowich

Answer:

16 pi cubic units

Step-by-step explanation:

Given that a region is bounded by

$f(x)=√x, y=0, x=1, x=4$

And the region is rotated about x axis.

We can find that here radius would be y value and height would be dx

So volume would be as follows:

If f(x) is rotated about x axis volume

= $\pi \int\limits^b_a {y^2} \, dx \\=\pi \int\limits^4_1 {x} \, dx\\=\pi *x^2 ^4_1\\= \pi*16-1\\=15\pi$

cubic units.

Consider a single spin of the spinner. Which events are mutually exclusive? Choose all that apply. a)landing on a shaded sector

denis23 [38]

Answer: the correct options are b and d.

Step-by-step explanation:

Let us first define what mutually exclusive events are. If two events are mutually exclusive, it means that they cannot happen at the same time. For example, getting a head and a tail at the same time are mutually exclusive.

Considering a single spin of the spinner, the events that are mutually exclusive are

b)landing on a shaded sector and landing on a 3. This is because 3 is unshaded. You can either land on 3 or an unshaded sector at a time

d)landing on an unshaded sector and landing on a number less than 2. This is because the numbers in the unshaded sectors are greater than 2.

1/2(4-+6x)=1/3x+2/3(x+9)

KonstantinChe [14]

Answer:

The value of x for the expression is 2

Step-by-step explanation:

Given algebraic expression as :

$\frac{1}{2}$ (4 + 6 x ) = $\frac{1}{3}$ x + $\frac{2}{3}$ ( x + 9 )

Now, solving the given expression

Or, $\frac{1}{2}$ × 4 + $\frac{1}{2}$ × 6 x = $\frac{1}{3}$ x + $\frac{2}{3}$ x + $\frac{2}{3}$ × 9

Or, $\frac{4}{2}$ + $\frac{6}{2}$ × x = $\frac{1}{3}$ x + $\frac{2}{3}$ x + $\frac{18}{3}$

or, 2 + 3 × x = $\frac{x}{3}$ + $\frac{2 x}{3}$ + 6

or, 2 + 3 × x = $\frac{2 x + x}{3}$ + 6

or, 2 + 3 × x = $\frac{3 x}{3}$ + 6

Or, 2 + 3 × x = x + 6

or, 3 x - x = 6 - 2

Or, 2 x = 4

∴ x = $\frac{4}{2}$

I.e x = 2

Hence The value of x for the expression is 2 Answer
