Question

The location between the park and Ray's

home is indicated in the graph.
Each unit represents a mile.
What is the distance, in miles, from the
park to Ray's home, rounded to the
nearest tenth?
A 16.6
B 15.6
C 14.1
D 143
E 11.0

Answer 1

A. 16.6

Explanation:

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

so this is our distance formula

now we need the two points

(-6, -6) and (3, 8)

lets plug these into our formula

d = sqrt{(3 - (-6))^2 + (8 - (-6))^2}

lets simplify

d = sqrt{(9)^2 + (14) ^2}

d = sqrt{277}

d = 16.64 or 16.6

Answer 2

The answer to the question is A-

16.6
