i used to use this website a lot for my AP Physics homework but now that I am done with that class I just come on here every once in a while to troll
Volume of solid: The region bounded above by the line y=4, below by the curve y=sqrt(x), and the y-axis, rotated along the line x=16?
The region bounded above by the line y=4, below by the curve y=sqrt(x), and the y-axis, rotated along the line x=16. Thanks in advance.
1 AnswerMathematics3 years agoThe region bounded by y = x, y = 8 − 3x, and the x-axis is rotated about the axis y = −1. Compute the volume of the resulting solid?
I am not sure whether to use shell or washer method, please help.

Calculus 2 help with volumes by cross section?
I am having trouble finding volumes by cross section please help
1 AnswerMathematics3 years agoCompute the gradient vector and find the tangent line of the level curve (in PARAMETRIC form?) f(x,y) = x^2 - xy + 3y^2 at the point (-4,4)?
The gradient vector is <-12,28>
The tangent line in parametric form is:
x = x(t) = ?
y = y(t) = ?
The tangent line in slope-intercept form is:
y = (12x+48+112) / 28
I don't know how to get it in parametric form.
1 AnswerMathematics4 years ago[Calculus III] What was the initial speed of the golf ball?
A golf ball is hit from ground level at an angle of 15 degrees above ground level. The terrain is level. The ball lands 49.0306 meters away.
What was the initial speed of the golf ball?
For that same initial speed, find two angles of departure for which the ball will travel to a distance of 39 meters.
Please explain how to solve, thank you.

Find the volume of the solid generated by revolving the described region about the given axis:
The region bounded above by the line y = 4, below by the curve y = sqrt{x}, and the y-axis, rotated along the following lines:
a. The x-axis (Used washer method and got the answer 128pi)
b. The y-axis (No idea how to do this)
c. The line y = 4 (Used disk method and got the answer 42.667pi)
d. The line x =16 (No idea)
I am stuck on parts b and d. Any help is greatly appreciated. Thanks in advance.
