isabella Went hiking she climbed park way up a mountain and stopped to have lunch then she climbed down. which graph could represent isabelles hike

Step-by-step explanation:

The speed one (c) is a red herring. Nothing we can see measures her speed.

The only graph that could possibly represent the right answer is D (first graph from the right). It shows that she topped 1/2 way up. It also shows that she took her time about coming down when she was at the top.

The only thing we don't know is A. What's on the vertical axis?

i not know

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
