Find the Vertex, Value of P, Axis of Symmetry, Focus, Directix, then graph the equation:

y + 2 = 1/4(x-1)^2?

I would appreciate any help on this! We are studying for an exam in my Algebra II class. Thanks in advanced!

Hello, we are studying for an upcoming exam and I would appreciate any help on these two questions:

Hello there! I'm preparing for an upcoming exam, and my teacher provided us with these sample problems:

There are three of them.

I would love and appreciate any and all help on them! Thanks so much in advanced! :-)

This is a review for the upcoming exam: http://imgur.com/zbNnDIs.jpg

I'm super nervous and stressed out because I'm really stuck on these two problems.

The teacher says to use the law of cosine but I'm so lost. :(

Any help would be much appreciated. I thank you kindly in advanced.

I'm literally to the point of tears!!

I CAN NOT GET THIS PROBLEM!! I AM SO FRUSTRATED!!!!

SOMEONE PLEASE HELP ME!!

The teacher provides me with this example:

Then has me do this sample problem:

Please, I am not looking for solutions, just simple explanations as to how they got 0.2857 on the example because I CAN NOT FIGURE IT OUT!! NO MATTER WHAT I TRY TO DO!!

I am sorry for typing in caps but I am just so sad and so stressed out!

THEY SHOW ME A SOLUTION BUT NOT HOW TO GET IT!! THEY ONLY SAY "SUBSTITUTE."

WHAT THE HECK!? HOW AM I SUPPOSED TO KNOW HOW TO DO SOMETHING WITHOUT AN EXPLANATION!?!

I seriously CAN NOT figure this out!! I am crying right now because I feel so dumb for not being able to figure out this damn problem!!

Please help! :'(

We are studying for an upcoming quiz and I would appreciate any help on these two questions!

1) One of the notes played by musical instruments has a frequency of 130.8 Hz. If an open organ pipe is to have this frequency as its fundamental, what is the length of the pipe if the speed of sound in the pipe is 350 m/s?

2) Explain, on the basis of the human retina why red, green, and blue are the primary colors of light.

Thanks so much in advanced!

Lucretia (a somewhat eccentric physics student) has her left ear against the concrete driveway. If someone drops a metal trash can onto the driveway about 30 m away (close enough to easily hear any sound made), will she hear one sound or two? If two, which one arrives first? Please explain your reasoning.

Any help would be appreciated! Thanks so much! :)

1. When a wave passes from one medium to another its speed changes. How will the frequency and wavelength in the second medium compare to their values in the first medium?

2. A radio wave from an FM station has a wavelength of 2.86 m. Where on the dial would it be (find the frequency in MHz).

This is a review for an upcoming exam, and I would appreciate any help. :)

Please help ! I've been stuck on these questions for over a day! I have some work to show for the first one but I'm really lost on the second one. Any help would be appreciated..

Here is my work for the first one:

y2-y1/x2-x1;

(0.125 - 512) / (5 + 7)

-511.875 / 12

-42.656 ~ -43

y - y1 = m(x - x1)

y - 512 = -42(x + 7)

y - 512 = -42x -294

y = -42x + 218

f(x) = -42x + 218

Is it correct?

Thanks a lot in advanced for your help!
