Calculating Velocity in a Pipe: Flow Rate 0.01, Diameter 90mm
What are the units for your flow rate? And also, Your equation for area includes the term D^2 which implies the diameter is being squared, so your answer for area should have the units mm^2.- JazzyJones

Do sound waves get bigger when they bounce off a wall?
Homework Statement The questions states, "If you speak while standing in a corner with your face toward the wall, you will sometimes notice that your voice sounds unusually loud. Explain."The Attempt at a Solution Is this because the sound waves are bunched up when they bounce off the corner...- JazzyJones

Solving by substitution for multiple variables
Thanks for the help. I found out my algebra is weaker than I thought. I am confused with how I can reduce all these divisions. For say equation A, I cannot see how to get all the a's on one side. For example, when b is subbed into a, Thanks for the help. I found out my algebra is weaker...- JazzyJones

Solving by substitution for multiple variables
equation for h was (13.1044+7.24h + h^2)/a^2 + (1.0816-2.08k + k^2)/b^2 = 1 equation for k was (4.4521 - 4.22h + h^2)/a^2 + (3.3124 - 3.64k + k^2)/b^2 = 1 although i changed the coordinates in equation for h with a 0 to make it simpler. And I also didn't multiply out the squares in the...- JazzyJones

Solving by substitution for multiple variables
when plugging b into the equation for a, I end up with as shown here, http://tinyurl.com/c2onxp7 then I simplified that down to a = ((4.95-k)(4.83-h)(-0.56-h))/(2.2-k)- JazzyJones

Solving by substitution for multiple variables
yes, however I changed the coordinates for equation h. Here are my equations with the new, correct equation for h. http://imgur.com/hwScn NOTE: the equations are not multiplied out like I did earlier, but it looks like you read them right. I also tried working with wolfram alpha with this...- JazzyJones

Solving by substitution for multiple variables
Homework Statement I have four equations and have four variables. I need to solve for each of the variables. I am having difficulty figuring out how to do this. My equations are here. http://imgur.com/EOA8I Homework Equations \frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} = 1 The Attempt...- JazzyJones

How to solve for four variables when two have first and second degrees
Ok I got them here, http://imgur.com/2KL0g the big K and little k are the same variable, i just wrote them like that sorry. Made a note of the missing k in the second equation and rewrote the number 7.66 for 7.66h in equation 4 I realize a matrix is used for this sort of thing sadly I don't...- JazzyJones

How to solve for four variables when two have first and second degrees
I have x and y values. I plug the four different coordinates into the second equation and get four equations. Then I solve using quadratic for h and k, (a and b can be solved without quadratic I believe). Then start plugging them into one equation at a time correct?- JazzyJones

How to solve for four variables when two have first and second degrees
Homework Statement does anyone know how to solve this equation for just x? x + x^2 = a^2*b^2 - 2.01j - j^2 - 15.132 it's possible right? because I'm trying to solve for four variables using four equations but two of my variables will have a first plus a second degree The...- JazzyJones

Predicting the distance where torque should be applied?
I'm taking a guess at this but what if I do this, .05kg*9.8m/s^2*.0217m = m*9.8m/s^2*.015 right? because the net torque will equal 0- JazzyJones
