Which situation would NOT represent a proportional relationship? A. The total amount of sugar s needed to make 6 batches of cookies if each batch needs 1 ¾ cups

B. The cost of ordering p pounds of peanuts for $7.00 per pound plus a shipping fee of $0.10 per pound.

C. The cost of filling up a gas tank g for $2.40 per gallon

D. The number of miles m that Maxine has run this year if she has already run 80 and will run an additional 12 each week

the answer is b

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

good luck on ur quiz test or homework. have a good day : )
