The value of y varies directly with c. If x = 2, then y = 7. Find the value of x if y = 84.​
shtirl [24]

Answer:

x=24

Step-by-step explanation:

y = x*c

x=2, y=7

2*c=7 => c=7/2

x*7/2 = 84

x = 84*2/7

x = 12*2

x = 24

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
