Answer: In-center of the triangle is point N.


Step-by-step explanation:

We are given a triangle △JKL.

In triangle △JKL, they drew perpendicular bisectors of each side of the triangle.

Also we are given angle bisectors of the each of angles in given triangle.

Note: Perpendicular bisector is a line that intersect a segment into two equal parts and also perpendicular to it.

<em>Also note that the in-center is the point forming the origin of a circle inscribed inside the triangle. It is constructed by taking the intersection of the angle bisectors of the three vertices of the triangle.</em>

<h3>We can see that angle bisectors are intersecting at a point N. </h3><h3>Therefore, in-center of the triangle is point N.</h3>

Use the quadratic formula to solve x^2-2x+2=0
Helen [10]
The quadratic formula is...
\frac{-b (+/-)\sqrt{b^2-4ac}}{2a}
your a will be in front of your x^2, b in front of your x, and c will be the number without an x. Plug those into the equation and you'll get two answers. That will be it

Answer:

  (c)  11

Step-by-step explanation:

As x goes up by 1, f(x) goes up by 2. The next line of the chart would be ...

  x = 4+1 = 5; f(x) = 9+2 = 11

The appropriate choice is f(5) = 11.

Two numbers whose sum is 44 and whose product is a maximum
Mashcka [7]

Answer:

x = y = 22

Step-by-step explanation:

It would help to know your math course. Do you know any calculus? I'll assume not.

Equations

x + y = 44

Max = xy

Solution

y = 44 - x

Max = x (44 - x)                    Remove the brackets

Max = 44x - x^2                   Use the distributive property to take out - 1 on the right.

Max = - (x^2 - 44x )               Complete the square inside the brackets.

Max = - (x^2 - 44x + (44/2)^2 ) + (44 / 2)^2 . You have to understand this step. What you have done  is taken 1/2 the x term and squared it. You are trying to complete the square. You must compensate by adding that amount on the end of the equation. You add because of that minus sign outside the brackets. The number inside will be minus when the brackets are removed.

Max = -(x - 22)^2 + 484

The maximum occurs when x = 22. That's because - (x - 22) becomes 0.

If it is not zero it will be minus and that will subtract from 484

x + y = 44

xy = 484

When you solve this, you find that x = y = 22 If you need more detail, let me know.
