G. Unit, Thanks. You can solve all my questions. You are very good.

can you help me on solving the attached question?

G. Unit, Thanks for answering my posting. I assume the first part of the answer is a typo. You mean to say "2!/1!(0!)". can you tell me what is the formula for NPR. I did not know the formulas, do you have some sort of materials to share with me on this topic? Thanks again.

Thanks suithink.

I found a previous posting, but I don't understand the explaination. Can someone help me to solve below question? Thank you. A certain restaurant offers 6 kinds of cheese and 2 kinds of fruit for its dessert platter. If each dessert platter contains an equal number of kinds of cheese and kinds of fruit, how many different platters could the restaurant offer? A. 8 B. 12 C. 15 D. 21 E. 27

Please help me to solve the attached question. Thank you. Ok. I figured it out. I just plugged in some numbers (2,0) and (100, 0) to find the y-intercept.

Rachita, Thank you for helping me to solve this question.

Can you help me to solve the attached question? Thank you.

Thanks suithink. I understand it now. So it will 1/2(1)(1). The value for both base and height are 1 (becuase the radius is 1).

How to solve the attached question? Can someone help me?

G. Unit, I did not understand the question. Thanks again for your help. Yes, the answer is A.

G. Unit, Thanks again for getting back to me.

G. Unit, Thanks for answering my posting. I did manage to get the area of the two diagrams, but I failed to see how you can come up with the two equations below: s^2/t^2=(2*Ö3)/4 (s/t) = Ö [(2*Ö3)/4] I can see the t^2 moved from the right side to the left side, but I don’t know why the 2 is there (on the right equation). Also, I don’t see how Ö [(2*Ö3) become 4Ö3. Can you explain one more time? Again, thanks for your help.

Can you help me solve this xy-plane question as well. See attached. Thanks in adavance.
