The graph below models the value of a $20,000 car t years after it was purchased which statement best describes why the value of the car is a function of years since it was purchased 1) each car value y is associated with exactly one time t 2) each t is associated with exactly one car value y 3) the rate at which the car decreases in value is not constant 4) there is no time t at which the value of the car is 0

step-by-step explanation:

84/3.5 = 24

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

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.
