Angles in a parallelogram have to equal 360.

Let x represent the measurement of the unknown angle.

2(55) + 2x = 360
110 + 2x = 360
2x = 250
x = 125

125 degrees

iVinArrow [24]

The number of lines and triangles illustrates combination

  • 36 lines can be drawn to join the nine points
  • 84 triangles can be drawn using the nine points

<h3>The number of lines that can be drawn</h3>

The given parameters are:

Total points, n = 9

Total points on each line, r = 2

The number of lines that can be drawn is then calculated  using the following combination formula

Lines = nCr

This gives

Lines = 9C2

Evaluate the combination expression

Lines = 36

Hence, 36 lines can be drawn to join the nine points

<h3>The number of triangles that can be drawn</h3>

The given parameters are:

Total points, n = 9

Total points on each triangle, r = 3

The number of triangles that can be drawn is then calculated  using the following combination formula

Triangles = nCr

This gives

Triangles = 9C3

Evaluate the combination expression

Triangles = 84

Hence, 84 triangles can be drawn using the nine points

What is 1.45 as a mixed number in simplest form?
g100num [7]
Answer is (1 9/20) because 1 and 45/ 100 can be simplified by divided 45/100 by 5.  45 divided by 5 is 9 and 100 divided by 5 is 20.  A mixed number is a combination of a whole number and a fraction.  The whole number is 1 and the fraction is reduced to 9/20.

A graph titled velocity versus time has horizontal axis time (seconds) and vertical axis velocity (meters per second). A line ha
AnnyKZ [126]

Acceleration is the change in velocity with respect to the time. The acceleration of the car at segment C is -30 meter per second squared. Hence the option B is the correct option.

<h3>Given information-</h3>

Segment A runs from 0 seconds 0 meters per second to 1 seconds 30 meters per second.

Segment B runs to 3 seconds 30 meters per second.

Segment C runs to 6 seconds 10 meters per second.

Segment D runs to 7 seconds 10 meters per second.

Segment E runs to 10 seconds 20 meters per second.

<h3>Acceleration</h3>

Acceleration is the change in velocity with respect to the time. Acceleration of a vector quantity which means it has both magnitude and the direction. It can be given as,

a=\dfrac{\Delta v}{\Delta t}

Here t denotes the time and v denotes the velocity of the body.

Acceleration at segment C,

a_c=\dfrac{10-40}{6-5}

a_c=-30

Thus the acceleration of the car at segment C is -30 meter per second squared. Hence the option B is the correct option.

Use the drawing tools to graph the distinct real zeros of the polynomial function p(x) = x3 - 2x2 - 4x2 + 8x.
vodomira [7]

Answer:

Step-by-step explanation:

My drawing tool is Desmos. It can be used at no cost.

the graph will not work unless you combine -2x^ and -4x^2 to give - 6x^2.

If you try and graph it as given, you get a straight line going for quadrant 4 to quadrant 2.

But you will note that when you make the addition of the 2 middle terms, it gives you the graph that I have enclosed, which is the one you should expect. I'm wondering why you get a straight line when you try and graph what you were given.
