8. the distance between (3,5) and (9, -3) is:
a. 100
b. 2137
c. 2135
d. 10

10 (Answer D)

Step-by-step explanation:

Here we see that the x-coordinate changes by 6, from 3 to 9, and that the y coordinate changes by 8, from 5 to -3.

We use the Pythagorean Theorem to calculate the distance between these two points.  One leg of a triangle here has length 6 and the other leg has length 8.  Applying this Theorem, we get:

6^2 + 8^2 = [ distance between (3, 5) and (9, -3) ]^2  =  d^2, and so:

d^2 = 36 + 64 = 100.

This distance must be positive.  Thus we take the positive square root of 100, which is 10.  10 is the distance between these two points.

answer. d.289 hope that

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
