The figure shows a circle circumscribed around a triangle. what is constructed first when creating the circle?
vampirchik [111]

Answer:

Option B is right

Step-by-step explanation:

We have in a triangle there are some properties inherent.

One is the perpendicular bisectors of all sides are concurrent.

These three concur at a point called the circumcentre of the triangle.

When we draw perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistance from A and B.

When we take the point of intersection of perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C

In short this is equidistant from all 3 vertices and hence is centre of circumcicle of triangle ABC

9-5 1/2 x - 3 (-2x+1)
Stells [14]
First, distribute the -3(-2x + 1). 
-3 x -2x = 6x      -3 x 1 = -3       -3(-2x + 1) = 6x - 3
Now we have: 
9 - 5 1/2x + 6x - 3 
Combine like terms. 
-5 1/2x + 6x = 1/2x         9 - 3 = 6
The two terms we are left with are 1/2x and 6. 
The simplified version of this expression is 1/2x + 6. 
Hope this helps!

Determine if the function is an even function, an odd function or neither.
Fynjy0 [20]

Answer: Option a.

Step-by-step explanation:

By definition, a functioon is even when:

f(x)=f(-x)

And it is odd when:

-f(x)=f(-x)

Therefore, you can verify if the function is even substituting -x into the function:

f(-x)=2(-x)^{4}+2(-x)^{2}\\f(-x)=2x^{4}+2x^{2}

Then:

-f(x)=f(-x)

It is an even function.
