The function yields the average cost in dollars per cup of lemonade made by lincoln at his lemonade stand when he makes x cups of lemonade. which statement best fits the situation modeled by the function? lincoln sells lemonade for 25 cents a cup. lincoln gave away 30 cups of lemonade for free. lincoln uses 25 cents worth of supplies per cup. lincoln uses 30 cents worth of supplies per cup.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

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
