Is log10Z the same as logZ??

also if someone plots log10Z instead of lnZ, would it affect the value of m from the equation lnZ= mx +c

Deer jumps over fence
With graceful leaping beauty.
Sine curve models height.

Six feet above ground,
Each leap requires 1 second.
The equation, please?

When t=o
The deer is over the fence
At its maximum height.

I dont know what the period would be for this problem. Can someone help me find the sine and cosine equation for this. I don't know if it wants the cosine or sine equation. It would be nice if you showed the steps also. Thanks!

Could someone please explain to me how the following expression equals 0? I've done it out, but I'm having trouble seeing why.

1/2 ∫ x*e^(px) dx + 1/2 ∫x*e^(-px) dx

Here, the limits on the first integral go from negative infinity to 0 and the limits on the second integral go from 0 to infinity.

I only have a question. I am doing my math homework and a question says: Express the Volume (V) of the cylinder as a function of radius (r).
Does this mean that I have to solve for the radius (r)?
Thank You!
