Airline A flight from Chicago to San Diego arrives 4 hours after depature. During the same time frame, Airline B flight from San Diego arrives 3.5 hours after departure. Assume the each plane is traveling at the same average speed, determine their average speed in still air and the average speed of the wind due to the jet sream. The distance between each city is approx. 1750 miles.

Anyone who can help will be greatly appreciated!! Please explain how you arrived at your answer!!

I apologize, I didn't know which catagory to put this under!!

Using the simple formula ( x - y )^2 = x^2 + y^2 - 2*x*y
I have proved that 2 = 4

Here is the proof:-
-8 = -8
4-12 = 16-24 (since 4-12= -8 & 16 –24 = -8)

Now add 9 to both sides
4 – 12 + 9 = 16 – 24 + 9
2*2 - 2*2*3 + 3*3 = 4*4 – 2*4*3 + 3*3
2^2 - 2*2*3 + 3^2 = 4^2 – 2*4*3 + 3^2
this steplooks like the formula x2 + y2 - 2*x*y = ( x - y )2

( 2 – 3 )^2 = ( 4 – 3 )^2
So 2 – 3= 4 – 3
Add 3 to both sides
2 = 4

try to find the mistake in this

Is there by any chance something analogous to a ratio test, but for covariance matrices instead of variances? I know how to use the F-test for variances, but I would like to compare covariance matrices to see what I can learn about goodness of fit for nonlinear regression, looking at fits using different numbers of parameters (in this case, summing different numbers of exponentials to get my fit function).

I know the answer is x^2=-6y (or that is the given answer), but I need to know how they got it. Thanks.

PS, the vertex is 0,0. My professor didn't go over this at all and if I see one worked out I'm sure I can do the rest.

I'm asking to see how this problem is worked so I can know how to do the rest, so please don't post links. Thanks in advance.
