Question

Look at points C and D on the graph:

What is the distance (in units) between points C and D? Round your answer to the nearest hundredth.

5.50 units
6.40 units
9.00 units
41.00 units​

Answer 1

It is 6.40 units.
To determine distance between two points, use the pythagorean theorem.
5^2 + 4^4 = c^2
25+16=c^2
41=c^2
c=square root of 41

Answer 2

I think its 6.40 but I'm not sure.
