The answer should be A. If you need work I can show you.
Answer:
Step-by-step explanation:
Using the cosine theorem:



The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees
Answer:
b=200 and m=200
Step-by-step explanation:
There are many answers to this problem. You can replace b and n for the number 200. You need to find what two numbers, added up, will give you 400. If b=200 and m=200, when added up, it will give you 400.
There are
ways of picking 2 of the 10 available positions for a 0. 8 positions remain.
There are
ways of picking 3 of the 8 available positions for a 1. 5 positions remain, but we're filling all of them with 2s, and there's
way of doing that.
So we have

The last expression has a more compact form in terms of the so-called multinomial coefficient,

It’ll be the one on the far right last one ;)
