I've been having a lot of difficulty with this 3 dimensions. Can you please help!!
Show the equation 4x^2+4y^2+4z^2-12x+3y-5z =0 represents a sphere and determine its center and radius.

Also explain why the equation x^2+y^2-2xy +5 = 0 does not represent a sphere

Lastly, Describe the region represented by the equation x^2 +y^2+z^2 - 4x +2y - 6z + a > 0 for the following values of a:

(j) a = 0 (ii) a = 14 (i) a = 20.

any help is greatly appreciated and thanks alot for your time

I'm stuck on these 3 problems.

1.) The time t (in seconds) that it takes for a pendulum to complete one period is approximately t = 1.1 square root of L, where L is the length (in feet) of the pendulum. How long is the period of a pendulum of the length 10 ft?

2.) The time t (in seconds) that it takes for a rock to fall a distance d (in meters) is approximately t = 0.45 square root of d. How long does it take for the rock to fall a distance of 200 m?

3.) Explain why n square root of a (little n in front of the square root) and a real nth root of a need not have the same value.

PLEASE HELP! I will give best answer!

I can get the correct integral but when I calculate the definite integral using the limits of integration I get the wrong answer. I know you have to change the limits of integration during the problem since you use u-substitution but I still get the problem wrong. I would really appreciate any help!
