Which of the following statements are true? Check all that apply. The speed of a baseball crossing home plate after being pitched depends on its initial velocity. If thrown at 74 mph, the speed over home plate will be 44.7mph.

A. Speed(50) = 44.7

B. Speed(74) = 72.2

C. Speed(72.2) = 74

D. Speed(44.7) = 50

question:

could we have options?

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer: 12

step-by-step explanation:

because yes

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.
