A student draws two parabolas on graph paper. Both parabolas cross the x-axis at (-4.0) and (6, 0). The y-intercept of the first
parabola is (0, -12). The y-intercept of the second parabola is (0, -24). What is the positive difference between the a values for
the two functions that describe the parabolas? Write your answer as a decimal rounded to the nearest tenth.

The answer is 0.5

The other is incorrect, so don't put that answer in. Hope this helps!

yep, o.5 is correct

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
