What are the inputs of the following function?

{(-3, 2), (-4, 2), (8, 3), (7, 1)}

{-4, -3, 7, 8}
{1, 2, 3}
{-4, -3, 1, 2, 3, 7, 8}
{1, 2, 3, 7, 8}

Step-by-step explanation:

i just got that on one of my assigments  and that was the correct answer.

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
