(n+1)! is equal to (n+1)*n*(n-1)*(n-2)...*3*2*1. Basically, it multiplies together every positive integer that is at most n+1. This is the definition of the !, or the factorial function.
(n+2)! is equal to (n+2)*(n+1)*n*(n-1)*(n-2)...*3*2*1, using the same definition. This thus is equal to (n+1)!*(n+2), so we have:
(n+1)!/(n+1)!(n+2), or:
1/(n+2)
This is our final simplification.
Answer:
Yes. Ponds can have gallons of water. 16 oz could be the weight of a loaf of bread.
115 is the slope, and 5 is the y intercept. They tried tricking you by making x turn into m so you think you don't know the slope
Answer:
7 Artichokes
Step-by-step explanation:
To figure this out, we need to find out how much Vitamin C an average adult needs. We set up a proportion.
Now, since each artichoke is worth 9 milligrams, we divide 60 by 9.
So, to get the necessary amount of Vitamin C, we round up to 7.
Answer:
196 square feet
Step-by-step explanation:
The top and bottom faces are congruent, the front and back faces are congruent, and the left and right faces are congruent.
SA = 2(l)(w) + 2(l)(h) + 2(w)(h) = 2(10)(8) + 2(10)(1) + 2(8)(1) = 196 square feet
