Answer:

I'm going to say a arithmetic sequence

Step-by-step explanation:

I say this because a arithmetic sequence of numbers such that the difference between the consecutive terms is constant. Difference here means the second minus the first. For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with common difference of 2. So, when Nya sent the letter to 4 friends, her friends copied and sent it to four other friends. So, the sequence would be (if it continues) 4, 8, 12, 16, 18, etc.

Write 22.056 in an expanded form

Answers

We know the first place after decimal is tenths

The second place after decimal is hundredths

The third place after decimal is the thousandths place

So for 0.056

0 is at the tenths place

5 is at the hundredths place

and 6 is at the thousandths place

Expanding 22.056 we get

22.056 = 20 + 2 + 0.05 + 0.006

OR

22.056 = 20+2+(5)/(100)+(6)/(1000)
20.000 + 2.000 + .050 +.006

Functions f(x) and g(x) are shown below.f(x) = x^2
g(x) = x^2 8x 16
In which direction and by how many units should f(x) be shifted to obtain g(x)?

Answers

We can factor g(x) as (x+4)^2.  Clearly, g(x) is simply f(x+4), so f(x) should increase each x by 4 to achieve the same result as g(x).  Therefore, f(x) should be shifted 4 units in the positive-x (or right) direction.
