Answer:

y=(x-4)²

Step-by-step explanation:

(a-b)²=a²-2ab+b²

(x-4)²=x²-2×x×4+4²

Answer:

y=(x-4)²+1.

Step-by-step explanation:

1) if to re-write the given equation y=x²-8x+C, then 'No Roots' is possible, if C>16;

2) among the given answers the only has 'No roots', it is y=(x-4)²+1, in it C=17.

What is the quotient of 2 by 1/2 to 5/8

Reika [66]

If you would like to find the quotient of 2 1/4 and 5/8, you can calculate this using the following steps:

2 1/4 = 9/4

2 1/4 / 5/8 = 9/4 / 5/8 = 9/4 * 8/5 = 18/5 = 3 3/5

The correct result would be 3 3/5.

A circle on the coordinate plane has a diameter

Llana [10]

9514 1404 393

Answer:

a. (10.5, 8)

b. 9

c. 4.5

d. (10.5, 12.5)

Step-by-step explanation:

a. The center of the circle is the midpoint of the diameter. Its coordinates are the average of the end point coordinates.

C = ((6,8) +(15, 8))/2 = (21, 16)/2 = (10.5, 8) . . . circle center

b. The diameter lies on the horizontal line y=8, so its length is the difference of the x-coordinates of the end points: 15 -6 = 9 . . . circle diameter

c. The radius is half the diameter: 9/2 = 4.5 . . . circle radius

d. Another point on the circle will be 4.5 units from the center on the same vertical line: (10.5, 8) +(0, 4.5) = (10.5, 12.5) . . . another point on the circle
