Nadia says the hypotenuse of this right triangle has a length of 73 because the Pythagorean theorem states that (28 + 45) squared = 73 squared

Wrong

Step-by-step explanation:

the Pythagorean theorem is x^2+y^2=z^2 Not (x+y)^2=z^2 so Nadia is wrong

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
