Answer:

What is the question

Step-by-step explanation:

Have a great day

You might be interested in
Sam is tiling a floor. He will use the same repeating pattern for the entire floor. The rule is "Blue Tile, White Tile, Black Ti
snow_lady [41]

If he uses 85 tiles, 28 tiles will be black

<h3>Sequence and Pattern</h3>

The formation of the tiles of the floor follows an arithmetic sequence or pattern

The pattern is given as:

  • Blue
  • White
  • Black

<h3>Formation of the tiles</h3>

Given that the total number of tile used is 85, and the black tile is always in the third position.

The highest number less than or equal to 85 that is divisible by 3 is 84.

Next, we divide 84 by 4

n = \frac{84}{3}

n = 28

Hence, 28 of the tiles will be black

1) x^2=36
x=6

3) x^2-8x+13=0 —> x= (8±√64-4(1)(13))/2(1)
x=4±√3

5) x^2-6x+9-k=0 —> x=(6±√36-4(1)(9-k))/2(1) —> (6±√4k)/2 —> (6±2√k)/2
x=3±√k

7) y=x^2-4x+11 —> y-11=x^2-4x —> take the half of the coefficient of the single x term and square it and add it on both sides —> y-11+4=x^2-4x+4 —> y-7=(x-2)^2 —> y=(x-2)^2+7
Minimum: (2,7)
Maximum: n/a
X intercepts: none (never crosses the x-intercept)

9) y=x^2+2x-8 —> y+8+1=x^2+2x+1 —> y=(x+1)^2-9
Minimum: (-1,-9)
Maximum: n/a
x-intercepts: (x+4)(x-2) —> (-4,0),(2,0)

11) c

13) (x+7)(x+3)
