The direct variation between x and y may be written as,
                                    y = kx
where k is the constant of variation. From the first set of values of the variables,
                                 12 = k(8)
the value of k is 1.5. Substituting the next set to the same equation,
                                 y = 1.5(14) 
The value of y is 21.

Contact [7]

3 + 2 + 1 = 6

270 ÷ 6 = 45

45 × 3 = 135

45 × 2 = 90

45 × 1 = 45

3 : 2 : 1

135 : 90 : 45

tatyana61 [14]

Answer:

The number of follower after x years is  40,000(1.025)^{x}

Step-by-step explanation:

Given as :

The number of current followers = p = 40,000

The rate of growth of follower = r = 2.5%

The time period of growth = t = x years

Let The number of follower after x years = A

<u />

<u>Now, According to question</u>

The number of follower after x years = number of current followers × (1+\dfrac{\textrm rate}{100})^{\textrm time}

Or, A = p × (1+\dfrac{\textrm r}{100})^{\textrm t}

Or, A = 40,000 × (1+\dfrac{\textrm 2.5}{100})^{\textrm x}

Or, A = 40,000 × (1.025)^{x}

So, The number of follower after x years = A = 40,000 × (1.025)^{x}

Hence, The number of follower after x years is  40,000(1.025)^{x}  Answer
