Question 12 Which of the following is an arithmetic sequence that could be modeled by an explicit formula expresed as a linear function?
A
1, 3, 6, 10, 15, 21, ...
B
- 1,0, 1, 0, 3, 0, ...
С
0, 3, 8, 15, 24, 35, ...
D
9, 4, -1, -6, - 11, - 16, ...

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

your question is incomplete, write all the numbers in the sequence that it tells you.
