Answer:

a. no

Step-by-step explanation:

The sequence is arithmetic.  It has a common difference of 14.

7 + 14 = 21

21 + 14 = 35

35 + 14 = 49

A geometric series has a common ratio (multiplication).  For example:

7 × 3 = 21

21 × 3 = 63

63 × 3 = 189

Consider the expression √(√625).
const2013 [10]

Answer:

5

Step-by-step explanation:

Square Root - Finding a number that multiplies itself twice into the number within the square root

With this meaning, we need to find a number that multiplies itself into 625.

Finding calculations using exponents will help,

25^2 is equal to 625. Therefore \sqrt{25}

We are not finished, as there is another square root right after, empowering the parenthesis, so what number multiplies itself equals 25?

This would be 5, therefore \sqrt{(\sqrt{625}) } is equal to 5.

Write a rule for the function:
Pepsi [2]

Answer:

y = 3^(x + 1).

Step-by-step explanation:

Here the y values are increasing by a factor 3  and when x = 0 y = 3,

so  y =  (3)^1 when x = 0  - that is y = (3)^(0 + 1)  = 3.

So y = 3^(x + 1)  is the rule.

Check: when x = -2,  y = 3^(-2+1) = 3 ^-1 = 1/3.

When x = 1, y = 3(1+1) = 3^2 = 9.
