A hiker, climbing the Organ Mountains, in four hours, went from a height of 256 feet to the height of 892 feet. Calculate the hiker's vertical speed.

2.65 feet per minute or 0.0441667 feet per second

Step-by-step explanation:

if x decreases by 4 then y increases by 10

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.
