Let the region R be the area enclosed by the function f(x) = x and g(x)
Find the volume of the solid generated when the region R is revolved about the line
y = 4. You may use a calculator and round to the nearest thousandth.

What is the solution to the system of the equations? x = y - 3 x + 3y = 13

Find the value of x for which the lines are parallel.

Someone answer asap for ! a ball is rolled down a ramp. the height, f(x), in meters, of the ball x seconds after it is released is modeled by the function f(x) = x²- 10x + 25 for all values of x from 0 to 5. which statement about the ball is true? a. the maximum height of the ball is 5 meters b. the height of the ball increases from 0 to 5 meters above the ground. c. the ball has traveled 5 meters when it reaches the bottom of the ramp. d. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp
