Question

What is the distance from (–3, 1) to (–1, 5)? Round your answer to the nearest hundredth. (4 points)

A. 3.60

B. 4.12

C. 4.47

D. 5.66

Answer 1

C. 4.47

Explanation:

The distance between two points is found by

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

= sqrt( (-1--3)^2 + (5-1)^2)

= sqrt( (-1+3)^2 + (5-1)^2)

= sqrt( (2)^2 + (4)^2)

= sqrt(4+16)

= sqrt(20)

4.472135955

Rounding to the nearest hundredth
