16. Find the length of the median CD.
hodyreva [135]

Step-by-step explanation:

16. Length of a line = sqaureroot of ((x1-x0)^2 - (y1- y0)^2)

C (2,-3) D (6,3)

CD = sqaureroot of ((6-2)^2 + (3-(-3))^2)

CD = sqaureroot of ( 16 + 36)

CD = sqaureroot of 52 = 2 root 13 = length

17. E (5, - 1) because the point is under the x axis.

Midpoint = ((x1+ x0)/2 , (y1 +y0) /2)

B (8,1) C (2, - 3)

Midpoint of BC = ((2+8)/2 , (-3+1)/2)

= (10/2 , - 2/2)

= (5, - 1)

18. Length of AE

A (4,5) E(5,-1)

Square root of ((5-4)^2 + (-1-5)^2)

Square root of (1^2 + - 6^2)

Square root of ( 1 + 36)

Square root of 37 = root 37
