The <em>correct answers</em> are:
y = 0.10x + 2.50; $5.
Explanation:
Using a graphing calculator, we enter the data in the STAT function. The year will be the independent (x) variable and the cost will be the dependent (y) variable.
For the year, instead of starting at 1998, we will start at 0, since that is where we started measuring. This means the year 2000 will be 2; 2002 will be 4; etc, up to x=10.
Running the linear regression, the calculator gives us a slope of 0.10 and a y-intercept of 2.499, or 2.50. This makes the equation y = 0.10x + 2.50.
To predict the price in 2023, we first find what our x-value will be. Subtract 1998 from this:
2023-1998 = 25
Now substitute 25 in place of x in the equation:
y = 0.10(25) + 2.50 = 2.50 + 2.50 = 5

<h3><u>Radius as function of volume is:</u></h3>
<em><u>Solution:</u></em>
<em><u>The volume of cone is given as</u></em>:
Where,
r is the radius
h is the height
From given,
height = 20 inches
From formula,
Rearrange , so that r is alone in left side of equation
Substitute h = 20
Thus, radius as function of volume is:
1. Page 1-9 (1digit/page
x 9page) = 9 digits = 9 page
2. Page 10-99 (2digits/page x 90page)= 180 digits = 90 page
3. Page 100-999 (3digits/page x 900page)= 2700 digits = 900
page
2,929 total digits – (9 digits + 180 digits + 2700 digits)= 40
digits
Since there are only 4 digits after page 999 we divide 40/4
= 10, thus there are 10 more pages after 999
So the book has 1009 pages.
Hope
this answer will be a good help for you.
