Question

Find the distance between (1, 4) and (3, 9). Round the answer to the nearest hundredth.

a. 5.39 units
c. 4.32 units
b. 7.28 units
d. 8.12 units

Answer 1

The answer is "A"

I got it correct on my Edmentum Test

Explanation:

Answer 2

To calculate the distance between these two points, we use the Pythagorean theorem since the two points can form a right triangle when plotted where the hypotenuse would be the distance between these two. We do as follows:

d = √[(x2-x1)^2 + (y2-y1)^2]
d = √[(3-1)^2 + (9-4)^2]
d = √29 = 5.39 units

The correct answer is A.
