Determine which of the following relations is a function. A 2-column table with 5 rows. Column 1 is labeled x with entries negative 10, negative 5, 0, 5, 10. Column 2 is labeled y with entries 10, 5, 0, negative 5, negative 10. A 2-column table with 5 rows. Column 1 is labeled x with entries negative 3, negative 1, 0, 0, 3. Column 2 is labeled y with entries 2, 1, 2, 1, 4. A 2-column table with 5 rows. Column 1 is labeled x with entries negative 8, negative 2, 1, 2, 4. Column 2 is labeled y with entries negative 4, negative 2, 3, 4, 6. A 2-column table with 5 rows. Column 1 is labeled x with entries 0, 1, 2, 2, 5. Column 2 is labeled y with entries 2, 4, 2, 6, 7.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
