Sarah kicked a ball in the air. The function F models the height of the ball (in meters) as a function of time (in seconds) after Sarah kicked it. Which of these statements are true? A: Sarah kicked the ball from a height of about 1 m. B: Sarah kicked the ball from a height of about 14 m.
C: At it’s highest point, the ball was about 1.75 m above the ground.
D: At it’s highest point, the ball was about 14 m above the ground

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

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.
