Which relation is a function of x? {(1, 2), (7, 6), (3, 2), (1, 0), (5, 6)}
A 2-column table with 4 rows. Column 1 is labeled x with entries 0, 0, 0, 0. Column 2 is labeled y with entries 2, negative 6, 9, negative 7.
x = 3 y squared minus 7
On a coordinate plane, a graph curves up, then curves down, and then curves up again.

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

actually what is a question i don't understand
