4/6 = 2/3

6/8 = 3/4

2/3 = 8/12

3/4 = 9/12

8/12 < 9/12

2/3 < 3/4

4/6 < 6/8

How many solutions exist for the given equation? 3(x + 10) + 6 = 3(x + 12) zero one two infinitely many

NNADVOKAT [17]

For this case we have the following expression:

$3 (x + 10) + 6 = 3 (x + 12)$

We must rewrite both sides of the equation.

For this, we use the distributive property.

We have then:

$3x + 30 + 6 = 3x + 36$

Adding similar terms we have:

$3x + 36 = 3x + 36$

We observe that we have two equal equations.

Therefore, the equations intersect for any value of x.

Thus, the equation has infinite solutions.

Answer:

infinitely many

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

Nadusha1986 [10]

Answer: $9.6\pi$

Step-by-step explanation:

Given

Curve is $y=3-3x^2$

boundary is y=0 i.e.

$\Rightarrow 0=3-3x^2\\\Rightarrow x^2=1\\\Rightarrow x=\pm 1$

The volume of solid generated when rotated about the x-axis is

$\Rightarrow V=\int_a^b\pi y^2dx$

Putting values we get

$\Rightarrow V=\int_{-1}^{1}\pi (3-3x^2)^2dx\\\\\Rightarrow V=\int_{-1}^{1}\pi(9+9x^4-18x^2)dx\\\\\Rightarrow V=\pi \left [ \frac{9x^5}{5} - 6 x^3 + 9 x\right ]_{-1}^{1}\\\\\Rightarrow V=9.6\pi$
