now, for a fraction, if its denominator ever becomes 0, the fraction becomes undefined, because it'd be a division by 0.
when does that happen? let's zero out the denominator to check,
x - 2 = 0, thus x = 2
so, if "x" ever becomes 2, the fractions goes kaput.
so, that domain is all real values except that one, that makes the fraction undefined.
I think the correct answer is option D. It would be rotational symmetry that allows a figure to remain congruent as it rotates around a point in its plane. It also known as a radial symmetry. A figure which has this type of symmetry would look the same after rotating the figure by any angle. The degree of this symmetry would range from 2 to any positive whole integer. It depends on the number of distinct orientations that the figure would look the same. Examples are the shapes such as rectangles, circles, squares, stars, hexagon, pentagon and all regular polygons.
The answer is
C. 0.4
1/2 is 0.5
so one down from it would be 0.4
Answer:
Step-by-step explanation:
We want to find the equation of a circle with a center at (7, 2) and a point on the circle at (2, 5).
First, recall that the equation of a circle is given by:
Where (<em>h, k</em>) is the center and <em>r</em> is the radius.
Since our center is at (7, 2), <em>h</em> = 7 and <em>k</em> = 2. Substitute:
Next, the since a point on the circle is (2, 5), <em>y</em> = 5 when <em>x</em> = 2. Substitute:
Solve for <em>r: </em>
<em />
<em />
Simplify. Thus:
Finally, add:
We don't need to take the square root of both sides, as we will have the square it again anyways.
Therefore, our equation is:
Answer:
The answer to your expression is 94.
Step-by-step explanation:
Given Expression -> 3 ( 7 - 5 ) + 8 ( 9 + 2 )
Order of Operations Parenthesis -> 3 ( 2 ) + 8 ( 11 )
Multiplcation Left to Right -> 6 + 8 ( 11 )
Multiplcation Left to Right -> 6 + 88
Addition -> 94
