Answer: B- A(n) = P+(n-1)i•P, where n is a positive integer
Step-by-step explanation:
Answer:
5) 15120
6) 11880
7) 336
Step-by-step explanation:
The formula for permutation where mPn is m!/(m-n)!
Applying this to question 5, we get 9!/4!, which is 15120.
For question 6, we get 12!/8!, which is 11880.
For question 7, we get 8!/5!, which is 336.
Answer:
The answer is one solution. It ends up equaling 7
Answer:
m=-3
x1,y1=1,-5
we have,
y-y1=m(x-x1)
y-(-5)=-3(x-1)
y+5=-3x+3
3x+y+2=0 is the required eqn
Answer:
B. -2.3
Step-by-step explanation:
It looks like the graph goes down about 7, and over 3, so B makes sense.
