Albert measured the rate of water pouring into his bathtub. his measurements showed that the relationship between the height (in inches) of the water in the bathtub, y, and the time (in minutes) that the water pouring, x, could be modeled by the equation y=6+0.50x. according to the model, how many minutes of the water pouring would cause the height of the water in the bathtub to increase by 1 inch?

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

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.
