Answer 1

Answer:

Keiko will have 200 subscribers first.

Step-by-step explanation:

Function describing the relation between the number of subscribers and number of months for Keiko is,

K = m² + 10

Where K = Number of subscribers

m = Number of months

If the number of subscribers are K = 200,

200 = m² + 10

m² = 200 - 10

m = √190

   = 13.78

   ≈ 13.8 months

Relation between subscribers and number of months for Jayden is given by the table attached.

Let the function is,

K = mx + b

Where K = number of subscribers

m = slope of the function

x = number of months

b = y-intercept

Slope of the linear function (from the table attached) is,

m = $\frac{56-48}{1-0}$

   = 8

y-intercept 'b' = Value of the function at x = 0

                       = 48

Therefore, function will be,

K = 8x + 48

200 = 8x + 48

8x = 200 - 48

x = 19 months

Therefore, Keiko will have 200 subscribers first.
