Which quadratic equation best models the data in the graph? y = 0.433x2 y = 2.31x2 y = (0.433x)2 y = (2.31x)2

I think it's A. y= 0..433x2

Step-by-step explanation:

I just had the question on E2020. (I know I'm late.)

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
