The tallest escalator on the london underground system is at angel station. it rises to a height of 90 feet over a horizontal distance of 200 feet. let e(x) be the height of one of the escalator's steps as a function of the horizontal distance from the bottom step. the following table shows the coordinates of a linear function. x ƒ(x) -5 -1 1/9 -4 -8/9 0 0 2 4/9 3 2/3 find and compare the rate of change of e(x) and ƒ(x). which function has the greater rate of change and by how much?

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

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.
