Question

For Items 9-11, determine the length of each segmentwith the given endpoints.9. C(1, 4) and D(11, 28)10. Y(-2, 6) and Z(5, -8)11. P(-7,-7) and Q(9,5)

Answer 1

Use the following formula:

d = √((x2-x1)² + (y2-y1)²)

9.

C(1,4) = (x1,y1)

D(11,28) = (x2,y2)

d = √((11-1)² + (28-4)²) = √((10)²+(24)²) = 29.73213749

10.

Y(-2,6) = (x1,y1)

Z(5,-8) = (x2,y2)

d = √((5-(-2))² + (-8-6)²) = √((7)² + (-14)²) = 15.65247584

11.

P(-7,7) = (x1,y1)

Q(9,5) = (x2,y2)

d = √((9-(-7))² + (5-(-7))²) = √((16)²+(12)²) = 20
