Answer:
a(n) = 13 - 2n
Step-by-step explanation:
The explicit formula variables are a(n) = a(1) + d (n - 1). The a(1) is your number you started out with, and the d is the common difference. From the recursive formula example, you see that your first number is 11 and your difference is -2.
1. Plug the numbers into the equation : a(n) = 11 - 2 (n - 1)
2. Distribute: a(n) = 11 - 2n + 2
3. Add like terms: a(n) = 13 - 2n
If you want to double check, you can plug 1 into n and see if you get 11. I did this, and I did so it should be correct. Hope this made sense! Have a great day :)
Answer:
650/per hour
Step-by-step explanation:
I got this answer by dividing 1,625 by the amount of hours it took to fill that much water, 2.5 so basically i divided 1,625/2.5 to get my answer.
Answer:
B and D
Step-by-step explanation:
One thing is for certain. The final answer will be 1/r^12 or r^(-12)
When written as the given of (r^-4)^3, the powers are multiplied.
The first one is false. There are 4 factors of r^-4 If you get an answer that says it is true, then the question means that r^-4 is 3 equal factors of r^-12
B is true
C: not true. The exponents are multiplied, not added.
D is true
E: not true. This is the same thing as C.
Answer:
