Mathematics

Given:

In a circle, two chords AK and LJ intersect each other inside the circle at M.

Measure of arc AJ = 65 degrees.

Measure of arc KL = 85 degrees.

To find:

The measure of angle KML.

Solution:

Intersecting chords theorem: According to this theorem, if two chords intersect each other inside the circle then the measure of angle on the intersection is half of the sum of intercepted arcs.

Using Intersecting chords theorem, we get

m\angle KML =\dfrac{1}{2}(arcKL+arcAJ)

m\angle KML =\dfrac{1}{2}(85^\circ +65^\circ )

m\angle KML =\dfrac{1}{2}(150^\circ )

m\angle KML =75^\circ

Therefore, the measure of angle KML is 75 degrees.

Which transformation produces another triangle that has the same area as the one shown?
vfiekz [6]

Answer:

A reflection in the line y = -2, then a translation 2 units right.

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Rigid transformation are transformation that preserves the shape and size of the object. Rotation, reflection, translation are rigid transformation whereas dilation is not a rigid transformation.

Any transformation regarding dilation changes the side length of the object and hence the area.

From the question, only one option is right. The rest options are not right because they involve dilation. The correct option is:

A reflection in the line y = -2, then a translation 2 units right.

9.35 as a fraction in simpliest form
Lana71 [14]
We know that
the number 9.35
is equal to 
9+0.35
and
0.35  is equal to
35/100
divide by 5 both members
\frac{35}{100} = \frac{7}{20}

therefore

the number 9.35  is equal to  9  \frac{7}{20}

Given the function h(a) = -x^2+ 7x + 14, determine the average rate of change
Yakvenalex [24]

Answer:

- 2

Step-by-step explanation:

The average rate of change of h(x) in the closed interval [a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [a, b ] = [1, 8 ], thus

f(b) = f(8) = - 8² + 7(8) + 14 = - 64 + 56 + 14 = 6

f(a) = f(1) = - 1² + 7(1) + 14 = - 1 + 7 + 14 = 20

average rate of change = \frac{6-20}{8-1} = \frac{-14}{7} = - 2
