If the length of one leg of a right triangle is 8 and the hypotenuse is 113−−−√, what is the length of the other leg?

  7

Step-by-step explanation:

The Pythagorean theorem tells you the sum of the squares of the legs is equal to the square of the hypotenuse. If x represents the unknown leg, this means ...

  x² +8² = (√113)²

  x² = 113 -64 = 49 . . . . subtract 8²

  x = √49 = 7 . . . . . . . . take the square root

The length of the other leg is 7.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
