Answer: 999999 plus 999999
Step-by-step explanation:
Answer:
105 pi m^2
Step-by-step explanation:
radius squared - radius squared =
(16+3)^2 - 16^2 =
19^2 - 16^2 =
361-256= 105
The question says kilograms every minutes, so it's C or D. The answers on A and B same
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
