9. a stock's price has been continuously declining at a rate of 5% per week. if the stock started at a price of
$62.50 per share, algebraically determine the number of weeks it will take for the price to reach $20.00 per
share. round your answer to the nearest tenth of a week

After 13.6 weeks the price per share will be $20.

Step-by-step explanation:

The stock's price has been continuously declining at a rate of 5% per week.

Now, if the stock's price is $62.50 per share at the start, then after w weeks the price will be dollars.

Hence, we have to find the value of w if the after w week price per share is $20.

So,

⇒

⇒

⇒ w = 13.6 weeks

Therefore, after 13.6 weeks the price per share will be $20. (Answer)

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

well what did you do it matters what you did : )
