Does this represent an exponential function?

Answer:

The function have a constant ratio

No, it does not represent an exponential function.

Step-by-step explanation:

As given,

Ines has saved $5. She doubles the amount she saves each week.

⇒ In first week she saved = $5

   In second week she saved = 2×$5 = $10

   In third week she saved = 2×$10 = 20

  In fourth week she saved = 2×$20 = 40

and so on..

∴ we get the series

5, 10, 20, 40 ,.......

If the series is given as a, b, c, d, ..... , then

The common difference is defined as d = b-a = c-b

The common ration is defined as r = \frac{b}{a} = \frac{c}{b}

Here, in the given question

The series is - 5, 10, 20, 40

This has no common difference , d =   10 - 5 (= 5 )≠ 20 - 10 (= 10)

As 5 ≠ 10

So the function does not define common difference .

Now,

This has common ratio , r =  \frac{10}{5} (=2) = \frac{20}{10}(=2)

As 2 = 2

So, the function represent common ratio

Now,

The function does not represent an exponential function because it is increased by common ratio.

What is the mean of this set {6,7,9,9,9}​
Naya [18.7K]

Answer:

8

Step-by-step explanation:

To find the mean, or average of a data set, add all the values together, then divide by the number of values.

The data set is: 6,7,9,9,9

1. Add all the values

Add 6,7,9,9 and 9

6+7+9+9+9

40

2. Divide by the number of values

Count how many numbers are in the data set. In this case, there are 5 numbers.

Divide 40 by 5.

40/5

8

The mean of the data set is 8.

The following figure is a rhombus. Find the value of m. Then, use that value to find the measure of VW
maxonik [38]

Answer:

  • m=8
  • The length of VW = 36 units.

Step-by-step explanation:

We know that a rhombus is a quadrilateral with four sides. All four sides have the same length.

From the diagram, it is clear that

  • The length of VW= 6m-12
  • The length of WX = 4m+4

As all the four sides of the rhombus have equal length.

So we can observe

VW=WX

6m-12 = 4m+4

Add 12 to both sides

6m-12+12=4m+4+12

6m=4m+16

2m=16

Divide both sides by 2

\frac{2m}{2}=\frac{16}{2}

m=8

so

The length of VW= 6m-12

                             = 6(8)-12  ∵ m=8

                              = 48-12

                              = 36

Thereofore, the length of VW = 36 units.
