Find the midpoint of the segment with the given endpoints.

Ksju [112]

The mid-point for given endpoints is (4,3)

Step-by-step explanation:

a mid-point is the point on a line segment that divides it into two equal portions.

If (x1,y1) and (x2,y2) are the coordinates of vertices of a line segment, then mid-point is given by:

$M = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

given

(x1,y1) = (9,9)

(x2,y2) = (-1,-3)

$M = (\frac{9-1}{2}, \frac{9-3}{2})\\\\=(\frac{8}{2}, \frac{6}{2})\\\\=(4,3)$

The mid-point for given endpoints is (4,3)

Find the number that should be added to the expression to make a perfect square k^2+11k

Alja [10]

k^2+11k has 11 as the coefficient of the first power of the variable (k).

To complete the square:

Take HALF of this coefficient. In other words, take HALF of 11, obtaining 11/2.

Square this (11/2): (121/4)

Add this 121/4 to k^2+11k

Result: k^2+11k + 121/4

This is a perfect square: k^2+11k + 121/4 = (k + 11/2)^2

Answer: The number to be added to k^2 + 11k to make it a perfect square is (121/4).
