Sorry, it seems cutting from Word and pasting here doesn't work. again the problem is. Solve for all values of c if 0 is less than or equal to x, which is less than or equal to 2pie. (cosine squared of 4x) + (cosine of 4x)=0 the answer is x= pie/8, 3pie/8...

For the first problem all you have to do is add 3 hours to 10:00am.(count 10:00 to 11:00 (1 hour), 11:00 to 12:00 (2 hours), etc.) For the second problem just count backwarks 8 hours (i.e. 3 hours earlier of 5:30 would be 2:30 (5:30 to 4:30 (1 hour), 4:30...

My teacher told me the answers were (-1,7) (-3,4) (1,4) and (-1,1). But i just didn't understand how to do it, the bell rang.

So far I got it down to ((4/3)n^3+(11/6)n^2)/((4/3)n^3)+(2n^2)+(2/3)n. Would I be able to cancel out the ((4/3)n^3)? So that it would be ((11/6)n^2)/((2n^2)+(2/3)n)? Or can I simplify that even futher by combining the n^2s?

Thanks for the advice Mrs. Sue that's exactly what I'll do. I also make up problems by myself and have someone check them for me.

I don't understand how you got from lim (1+sinx/x)/(1+cosx/x) to the answer. I know that sinx/x is 1 so would the top be 2?

where did you get f(x)=2x??

Thank you.

do you know how to use the diamond? or were you taught with the FOIL square?

16 years ago

Then you would use FOIL, and find which two numbers multiply to get 2, and add to get -3

All elements on the table are trying to get to the 8th column. Metals on the periodic table lose electrons. An example is aluminum. Aluminum needs three in order to reach the far right of the table. Don't move right, count three to the left. So you write...

Alright, I found -1/4cos(x)^4 but I didn't get the right answer. Did I dint the wrong anti-derivative? Do I have to do reverse chain rule and get... (-1/4cos(x))sin(x)^4?

For the speed at which the ball was launched I got 18.12m/s. That part was right according to the computer. I didn't understand parts b or c of the question. For part a you multiplied vt by .608 instead of .6018 and that is why I got a different answer. C...

Okay thanks, I'm writing a document based question and my teacher isn't very good at helping me with anything. I found the religions they gave me to work with so not helpful or relative to each other in anyway.

that is actually the answer (that my book gives) how did you get that??

15 years ago

Ok i got that too... it comes to a fraction but then when you check it in the equations you don't get the same answer.

The range can be found by plugging the values of the domain in the equation. For example, 3/(-3-6)=-1/3 -1/3 is part of the range because the range represents the outputs or y values that correspond to the inputs (the domain), or x values
