Find the volume of the solid generated by revolving the region bounded by the lines and curves about the x-axis. y = x, y =1, x
liraira [26]

Answer:

The volume is: V = \frac{\pi}{3} cubic units

Step-by-step explanation:

Volume of a solid:

The volume of a solid, given by the function f(x), over an interval between a and b, is given by:

V = \pi \int_{a}^{b} (f(x))^2 dx

y = x, y =1, x = 0

This means that the upper function is y = 1, and the lower function is y = x. So

f(x) = (1 - x)

The lower limit of integration is x = 0.

The upper limit is y = x when y = 1, so x = 1.

Then

V = \pi \int_{a}^{b} (f(x))^2 dx

V = \pi \int_{0}^{1} (1-x)^2 dx

V = \pi \int_{0}^{1} (1-2x+x^2) dx

V = \pi (x-x^2+\frac{x^3}{3})|_{0}^{1} dx

V = \pi(1 - (1^2) + \frac{1^3}{3})

V = \frac{\pi}{3}

H(t) = -16t^2 + 40t +120
stira [4]

Answer:

h(t) = -16t^2 + 40t + 120

h(t) = -16(t^2 - 5/2*t) + 120

h(t) = -16(t^2 - 5/2*t + (5/4)^2 - (5/4)^2) + 120

h(t) = -16(t^2 - 5/2*t + (5/4)^2 - 25/16) + 120

h(t) = -16(t^2 - 5/2*t + (5/4)^2) + 120 + 25

h(t) = -16(t - 5/4)^2 + 145
