Answer: The area of the notebook that the sticker covers is 128 cm^2
Step-by-step explanation:
The equation for the area of a rectangle should be:

-The height of the stickers measures 16 cm:

-So, if the base is half as long as the height, you divide it by 2:

-Then, you substitute it:
· 
-Result:

Answer:
a_n = 28-2n
Step-by-step explanation:
Given sequence is:
26,24,22,20
We can see that the difference between consecutive terms is same so the sequence is an arithmetic sequence
The standard formula for arithmetic sequence is:

Here,
a_n is the nth term
a_1 is the first term
and d is the common difference
So,
d = 24-26
= -2
a_1 = 26
Putting the values of d and a_1

Hence, the recursive formula for given sequence is: a_n = 28-2n ..
I think the answer is 2,612.48 because if you multiply the radius, 80 by itself you get 640. Then if you multiply 640 by 3.14 and then multiply the product by 1.3 you get 2,612.48.
