Answer:
1764 ways
Step-by-step explanation:
Number of ways of selecting 6 cows from 9 cows and 5 buffaloes from 7
Using the combination formula:
nCr = n! ÷ (n - r)! r!
Ciw selection:
9C6 = 9! ÷ (9-6)! 6!
9C6 = 84
Buffalo Selection:
7C5 = 7! ÷ (7-5)! 5!
7C5 = 21
9C6 * 7C5
84 * 21
= 1764 ways
Find the area of two sides (Length*Height)*2 sides.
Find the area of adjacent sides (Width*Height)*2 sides.
Find the area of ends (Length*Width)*2 ends.
Add the three areas together to find the surface area.
Example: The surface area of a rectangular prism 5 cm long, 3 cm. Hope this helps?!
If you are talking about finding the slope of BC then it looks like you have to find the square root of 3 which is approx 1.7 then find the slope.
slope equation is rise over run (or y over x): y1 + y2 divided by x1 + x2.
From this you should be able to find the answer
