To shift vertically the graph of the function 
, you have to add a constant to its expression:
If k is positive, you shift the function k units above, if k in negative, you shift the function k units below.
So, if you want to shift the graph of 
two units down, you have to subtract 2 (i.e., add -2):
Answer:1.00
Step-by-step explanation:
A=74-72/2.0
And I did it on kahn
7n-22 ≥ 64
1. Move constant to the right.
7n ≥ 64 + 22
2. Combine like terms.
7n ≥ 86
3. Divide 7n by 7 to get n alone.
n ≥ 86
4. Divide 86 by 7.
n ≥ 86 / 7 OR n ≥ 12.29
₇P₅ is a permutation. you can find this setting in the statistics menu of your scientific calculator (i think).
If you don't have a scientific calculator, you can use the following formula:
nPr = 
₇P₅ = 
= 
= 
= 7 * 6 * 5 * 4 * 3
= 2520
Answer: C
The answer is 2sqrt(8) . hope this helped
