Answer:
40,000 units on the first day then 18% per week
Step-by-step explanation:
Exponential function:
An exponential function has the following format:
In which r is the rate of change, as a decimal.
In this question:
The number of phones sold in thousands of units per day, in t weeks since the date of release, is:
Since , it solds 40,000 on the first week.
The rate of percentage increase is:
1 + r = 1.18
r = 0.18
So an increase of 0.18 = 18% a week.
So the correct option is:
40,000 units on the first day then 18% per week
A straight line is represented by a linear equation given below.
The points are given as (1, 2) and (4, 4).
Start by calculating the slope (m)
So, we have
The equation in slope-intercept form is then calculated as:
So, we have:
Expand
Take LCM
Multiply through by 3
3y=2x+4
So, the possible equations are:
