Ineed the answer for both of these fast .

1): 15, 2): 5

Step-by-step explanation:

I used the Pythagorean Theorem which is .

For 1), the equation is (12*12) + (9*9) = c*c OR 144 + 81 = c*c. I got 225 = c*c. Then I used a calculator to figure out the square root of 225 and I got 15.

For 2), the equation is (4*4) + (3*3) = c*c OR 16 + 9 = c*c. I got 25 = c*c. Then I used the calculator to figure out the square root of 25 and got 5.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals
