Ken

Is it somewhere on a circle R/3 from the disc center? Or just at its center?

How can do I solve this?

x(x-2)^2

and

x(x-1)^2

Thanks!

Evaluate the indefinite integral.

Only problem that is giving me issues :( Can you help?

A particle moves along a straight line with equation of motion s = f(t), where s is measured in meters and t in seconds. Find the velocity and speed when t = 6.

f(t) = (t ^ -1) - t

Velocity=

Speed=

I know how to do them when its like "2x - 4x^2" but not with the x^-1

Find f '(a)

f(x)= ((x^2) + 1) / (x - 6)

I came up with ((x^2) - 1) / x^2 so far, but not sure if this is correct or what I need to do next...

If a rock is thrown upward on the planet Mars with a velocity of 17 m/s, its height (in meters) after t seconds is given by H = 17t - 1.86t^2.

(a) Find the velocity of the rock after one second.

(b) Find the velocity of the rock when t = a.

(c) When will the rock hit the surface?

(d) With what velocity will the rock hit the surface?

I think that A is 13.28 m/s??? and i need this i think before i can do the others.

On D i thought it would be the same as Vinitial =17, but that was wrong.

y=(5x^3) - 6x at (-1,1) Can somebody explain to me how to do it by taking the derivative and solving with that?
