salantis [7]3 years ago
8 0

Answer:

circular plate

Step-by-step explanation:

Rotational symmetry is attained on a figure if it is possible to achieve the same image of the figure after rotating it. For example , rotating a circular plate marked with numbers 1 to 6 through a 360° rotation, the number marked 1 with attain a position similar like that before rotation.

Look at the adjoining figure and write 2 pairs of intersecting lines.​
Mashutka [201]

Answer:

  • Line AB and Line GH
  • Line CD and Line FF

Concept:

Intersecting lines are lines that overlap upon only one point. The number of lines can be two or more.

Intersecting lines can intersect at any angle.

Solve:

There are in total four intersecting points in the given figure.

As we can see from the figure, any two lines would intersect each other

Therefore, 2 pairs of intersecting lines can be any pairings of lines that are not in the same orientation.

  • Line AB and Line GH
  • Line CD and Line FF

Hope this helps!! :)

X2 - __________x + 144
Yakvenalex [24]

Answer:

the blank =24x

Step-by-step explanation:

Assuming the expression is x^2 - ________x +144,

you can tell that this is in the form of a^2 +2ab+b^2.

If the "a" is squared, you would get x^2. And if the "b" was squared then you would get b^2.

So as the result, the expression is

(x-12)^2= x^2-24x+144

Which function has a vertex at (2, –9)?
Ivahew [28]
The solutions or roots so-called are really just the x-intercepts, and for a quadratic equation, the vertex is found right half-way between those x-intercepts.

we can get the intercepts by zeroing out "y" or f(x), so let's take a peek at one of those,

\bf \stackrel{f(x)}{0}=(x-5)(x+1)
\\\\\\
0=x-5\implies \boxed{5=x}\qquad \qquad \qquad \qquad 0=x+1\implies \boxed{-1=x}

so, the x-intercepts or solutions are at 5 and -1, let's take a peek what's the halfway point.

-1----0----1----  2  ----3-----4------5

well then, now we know the vertex is at x = 2, but, what's the y-coordinate of it anyway?

y = (x - 5)(x + 1)

y = (2 - 5)(2 + 1)

y = (-3)(3)

y = -9
