Answer:
.
Step-by-step explanation:
We have been given that when a customer uses 14 GB, the monthly cost will be $55. When the customer uses 38 GB, the monthly cost will be $103. We are asked to write an equation in slope-intercept form, where x is the number of GB of data used in a month and y is the total monthly cost of the Blurizon plan.
We have been given two points on line (14,55) and (38,103).
Let us find slope of line.
Now, we will use slope-intercept form of equation.
Therefore, our required equation would be .
Answer:
(i) Approximately 3 half lifes
(ii)
Step-by-step explanation:
(i) ∵ The half life of Radon-222 is approximately 3.8 days,
So, the number of half life in 11.46 days = ≈ 3
(ii) Since, the half life formula is,
Where,
= initial quantity,
t = number of periods
= half life of the quantity,
Given,
N =
t = 11.46 days,
