3 0

Answer:

x^2 + y^2 - 12x + 4y + 40

Step-by-step explanation:

Open the parentheses:

(x - 6)^2 = x^2 - 12x + 36

(y + 2)^2 = y^2 + 4y + 4

Simplify:

x^2 + y^2 - 12x + 4y + 40

Which function BEST expresses the linear relationship displayed by the scatter plot?
Harrizon [31]

Answer:

C

Step-by-step explanation:

We want a line of best fit, which means we want to create a line that the data points will lie closest to.

One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.

Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:

(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4

Eliminate A and B.

Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.

The answer is C.

Which of the following is not part of polyhedron.
Rom4ik [11]

Answer:

C

Step-by-step explanation:

Oblique. The other three are used to describe a polyhedron. They are related by the following formula

V + F - E = 2.

Where

  • V = number of vertexes
  • F = the number of faces
  • E = edges

For example consider a common cube, like a sugar cube.

It has 6 faces (f)

It has 8 vertexes (V)

It has 12 edges. E

6 + 8 - 12 = 14 - 12 = 2

Area = πr^{2}

π * 17^{2} = 907.92

= 908 cm^{2}

=0.0908 m^{2}
