# What is the answer to (y-3)^2/16 - (x+2)^2/9=1 in hyperbola for, with the center, vertices, foci, asymps, and what a,b, and c equal?

Please show all work so I can understand how to do it this is my last problem and I am stuck.

# I need help trying to sole tan^2 x =1 where x is more than or equal to 0 but x is less than or equal to pi

this is what it looks like tan^2 x=1 where 0 ≤ x ≤ π

# Find two different sets of parametric equations for the following equation: y= (1/(x^3)) I need the answers to this.

I have the answers {x=2t, y=(1/8t^3) } and {x=t, y=(1/t^3)} If I have the wrong answers could you explain how to get the right ones? I have to answer this in class tomorrow and I'm insanely paranoid...

# A configuration of firewood is arranged in the shape of a triangle. If each piece of wood is 1 foot in length, what is the volume of the pile of wood?

I am having trouble setting this up. The problem includes a diagram of the wood set up one side measures 20ft another side measures 14ft. The angle is 50 degrees and the wood meaesures 1 foot in length...

# how do i solve these?

1/x = 4/3x + 1 1/R=1/R1+1/R2 solve for R1 a^2x+(a-1)=(a+1)x solve for x   How would I solve these? could you list the steps to solve these? Thanks!
