The equation models the height in feet reached in seconds by an object propelled straight up from the ground at a speed of 80ft/s.

Use the discriminant to find whether the object will ever reach a height of 90ft.

The discriminant is ___(3 number places.) Since it is Positive or Negative, the object Will or Will Not reach a height of 90ft.

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.
