Does the following table represent a proportional relationship, and if so what is the proportion of the cost for a box ofcereal to the size of the box? cost for a box of cereal $2.20 $2.64 $3.30 $4.84size of box (in ounces) 10, 12, 15, 22a. yes, $0.22 per ounceb. yes, $4.55 per ouncec. yes, $0.44 per ounced. no it is not proportional

answer: 3.26019516

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

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
