First, we get rid of the negative exponent in the parenthesis. We do this by moving it to the top. Our equation is now:
Next, we can cross out one n from both the top and the bottom.
Finally, we evaluate the -2
Our equation becomes:
This becomes:
This can not be simplified any further, so this is the final answer.
Answer:
y = 80+ 15*x
Step-by-step explanation:
members = initial membership + growth* months
y = 80+ 15*x
Answer: 1/10
Step-by-step explanation:
At the end of the day, she still had 2/5 of the book to read. Which meant that she had read 3/5 of the book. Since she read 1/2 of the book in the day, we would read 3/5 - 1/2 = 6/10 - 5/10 = 1/10 of the book at night.
1. 1,3,9,27,81
1*3=3
3*3=9
9*3=27........⇒ Geometric, common ratio is 3 --- B
3. 20,17,14,11
20 - 3 = 17
17 - 3= 14
14 -3= 11........⇒ Arithmetic , common difference is 3 ....D
4. 128, 32, 8, 2
32=128*1/4=128*0,25
8=32*0,25
2=8*0,25.......⇒ Geometric, common ratio is 0,25.......A
