9) Use Pythagorean Theorem
120² + 500² = d²
14,400 + 250,000 = d²
264,400 = d²
[tex]\sqrt{264,400}[/tex] = d
514.20 = d
Answer: D
10) Using Pythagorean Theorem, plot the coordinates to find the difference in the x-coordinates (base) and the difference in the y-coordinates (height) or use the distance formula.
7² + 4² = d²
49 + 16 = d²
65 = d²
[tex]\sqrt{65}[/tex] = d
8.06 = d
Answer: A
