Answer:
The answer is B
Step-by-step explanation:
In a function every X must have only 1 Y. In this example the x 3 has to y's 10 and 5, therefore making it not a function.
Answer:
The answer is (a²+1)(2a+1)
I'd suggest you write "6 2/5," not "6 and 2/5."
6 2/5 rotations
-------------------- =
2 2/3 seconds
32

5 32 3
------- = ------ * -----
8 5 8 Reduce that 32/8: obtain 4.
---
3
Then we have
4(3)/5, or 12/5 rotations per sec.
.21 as a percentage is 21%
You can divide 7.98 by 21 then multiply by 100 which gives you an answer of 38.
Hope this helps :)
