A rocket is launched from the top of a 50 foot cilt with an initial velocity of 170 feet per second. The height, h, of the rocket after t seconds is given by the equation ha - 16. 1701 + 50. How long after the rocket is launched will it be 20 feet from the ground?
motor derimal rounded to the nearest tenth of a second as needed.)

yes because they have the same amount of green and blur marbles.

step-by-step explanation:

probably .5

i can on others if necessary.

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.
