Answer:

Step-by-step explanation:

LM + MN = LN

x + 7 + 3x + 20 = 6x - 5

4x + 27 = 6x - 5

-4x -4x

27 = 2x - 5

+5 +5

32 = 2x

÷2 ÷2

16 = x

MN: 3x + 20

3(16) + 20

48 + 20

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 $128 \pi/5 units^3$

Find f(g(3). f(x)=2x-5 g(x)=1+x^2

serious [3.7K]

Answer:

f(g(3)) = 15

Step-by-step explanation:

g(x)=1+x^2

g(3) = 1 + 3^2 = 1 + 9 = 10

f(g(3)) = 2(10) - 5 = 20 - 5 = 15
