R(4, 2) and S(10, 10) are the endpoints of a line segment. What is the midpoint M of that line segment?
bogdanovich [222]

M = (7,6)

Step-by-step explanation:

formula to find mindpoint is

(\frac{x2 + x1}{2} \frac{y2 + y1}{2} )

(4,2) = (x1, y1)

(10,10) = (x2,y2)

now substitute those into the formula!

\frac{10 + 4}{2} \frac{10 + 2}{2}

now solve for x & y !!

x =  \frac{10 + 4}{2}  =  \frac{14}{2}  = 7

y =  \frac{10 + 2}{2}  =  \frac{12}{2}  = 6

so now that we have solved for x & y put it in point form and your done !!

point for is (x,y)

and thanks why the Midpoint is (7,6)

Answer:

153.86 units^2

Step-by-step explanation:

the area of a circle = pi * r^2

To find r, divide the diameter in half.

14/2 = 7

Now, area = pi * 7^2

= pi * 49

= 153.86

hope this helps!

Draw a conclusion from the given information. look at picture...<br> Thanks! Please help soon! :)
lesya [120]

Hey there! I'm happy to help!

When looking for a conclusion, we have to find something that we can figure out from the information but they don't directly tell us.

Answer B says that a conclusion is that the lines meet at a 90 degree angle, but they already told us that, so this is wrong.

Answer C does the same thing, so it is wrong as well.

A 90 degree angle is a right angle. They already told us that the lines intersect at a right angle, so this is not a conclusion.

Answer A says that the lines are perpendicular. They don't directly tell us that these specific lines are perpendicular, but from the information they gave us we can figure it out. Therefore, the correct answer is A. The lines are perpendicular.

Have a wonderful day! :D
