Step 1
<u>Find the equation of the line AB</u>
we know that
the equation of the line into point-slope form is equal to
Let
<u>Find the slope m</u>
we know that
the slope between two points is equal to
substitute
with the slope m and point A find the equation of the line AB
or
with the slope m and point B find the equation of the line AB
we will proceed to verify each case to determine the solution of the problem
Step 2
<u>Verify case A</u>
<u>Case A)</u>
the slope of the line is
but the point -----> not lie on the line AB (see the graph)
therefore
the case A is not the solution
Step 3
<u>Verify case B</u>
<u>Case B)</u>
the slope of the line is
and the point -----> is the point A
therefore
the case B is a solution
Step 4
<u>Verify case C</u>
<u>Case C)</u>
the slope of the line is
but the point -----> not lie on the line AB (see the graph)
therefore
the case C is not the solution
Step 5
<u>Verify case D</u>
<u>Case D)</u>
the slope of the line is -----> the slope is not equal to the slope AB
and the point -----> not lie on the line AB (see the graph)
therefore
the case D is not the solution
<u>the answer is</u>
The equation is a point-slope form of the line AB
A.
• To get the mean you add all the numbers and divide by how many numbers there are. All the numbers added is 255. Since there are 9 numbers you divide 255 by 9.
Mean: 28
• To get the median you order the numbers from least to greatest. The number in the middle is the median.
Median: 15
B. The mean would give her parents the most accurate phone information use because it tells the average amount of minutes she uses her phone per day.

Answer:
The surface area formula for a cone, given its diameter (or radius) and height, is π x (diameter / 2) 2 + π x (diameter / 2) x √ (diameter / 2) 2 + (height 2), where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is π x radius 2 + π x radius x √ (radius 2 + (height 2)
