An AMS baseball player hits a baseball into the air with an initial vertical velocity of 48 feet per second from a height of 3 feet. The path of the ball is modeled by the equation y = -16x2 + 48x + 3. After how many seconds does the ball reach its maximum height? And what is the maximum height?

found it xd it ok yt

50- 250 is correct i did that one too

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.
