Otrada [13]

Answer:

  C.  the initial number of club members, in hundreds

Step-by-step explanation:

The general form of such an expression is ...

  (initial value)×(growth factor per period)^(number of periods)

The use of 12 in the exponent suggests that the growth factor of 1.02 is an annual factor. If that is the case, for t months, the membership should be modeled as ...

  1.8(1.02^(t/12))

_____

As written, the expression is not an exponential expression. With appropriate parentheses, it might be a good model if t is the number of <em>years</em> (not <em>months</em>), and if the expected growth rate is 2% per month.

  1.8(1.02^(12t))

The sum of two numbers is 20. One number is one less than twice the second number. What are the two numbers?
murzikaleks [220]

Answer: Hope this helps.

13, 7

Step-by-step explanation:

Number one is 13

Number two is 7

Well 7 x 2 = 14, 14-1 = 7, and 7+13 = 20 making the answers true.

I figured out this number by eliminating numbers, I started with 5, ended with 8 to make a range of the possible numbers. Since 5 was too low and 8 was too high I knew the number had to be either 6 or 7, so I did 7 and I got the answer.

For questions 1-3, decide for each graph whether the equation shown is a function. Label each graph
ruslelena [56]

Answer:  Not a function

<u>Step-by-step explanation:</u>

The graph fails the vertical line test.  In other words, when you draw a vertical line anywhere through the curve, the line passes through two points.

Bonus: If you do not have a graph, it is not a function if there is one x-value that has two different y-values.

For example, If (1, 2) and (1, -2) lie on the curve, then it is NOT a function because the x-value (1) has two different y-values (2 & -2).
