3. 1st Attachment #19 I believe that I am suppose to multiply (x-2)(x+2) but what do i do about the symmetric with an origin?

2nd Attachment I do not get what they are asking for in the 2nd and 3rd part of the question can you please explain it to me.

3rd Attachment I am not sure if I did this problem right.
tan 1.2 = h/10
h = 25.72 km?

Thank You!

Did you plot your solution?

2nd Attachment I do not get what they are asking for in the 2nd and 3rd part of the question can you please explain it to me.

You need to find the x which satisfies x = .5 cos x.
They give pretty explict directions on how to start. Did you make the plot they ask for? if not do so.

3rd Attachment I am not sure if I did this problem right.
