Answer:
The rate of change in number of subscriber for the six years is 3.62%
Step-by-step explanation:
Given as :
The initial subscriber of newspaper = p = 10225
The subscriber of newspaper after 6 years of publish = P = 8200
The time period = t = 6 years
Let The average yearly rate of change = r%
<u>Now, According to question</u>
The subscriber of newspaper after n years = initial subscriber × 
Or, P = p × 
Or, 8200 = 10225 × 
Or,
= 
Or, 0.80195 = 
<u>Taking power
both side</u>
So,
= 
Or, 0.9638 = 1 - 
Or,
= 1 - 0.9638
Or,
= 0.0362
Or, r = 0.0362 × 100
i.e r = 3.62
So, The rate of change in subscriber = 3.62%
Hence, The rate of change in number of subscriber for the six years is 3.62% . Answer
Answer:
y = 15x + 200
Step-by-step explanation:
It should be y = 150x + 200 because if you look at the first one, 300x is too big.
You can cross out the last two.
Then you can see the second one also doesn't work.
Cross that one out.
The first choice is the only one.
