Step-by-step explanation:

The Exterior Angle is the angle between any side of a shape, and a line extended from the next side. Another example: When we add up the Interior Angle and Exterior Angle we get a straight line 180°. They are "Supplementary Angles".

Answer: Area= square

A=5×5= 25

A=triangle 1 & 3

5×10= 50÷2= 25 25+25=50

A=triangle 2&4

10×5=50÷2=25×2=50

Area of 1-4= 25+50+50= 125

A= 125

Answer:

(0, 0)

Step-by-step explanation:

(4+(-4))/2= 0/2= 0

(-5+5)/2=0/2= 0

(0, 0)- mid point

Answer:

[tex](4,-5);(-4,5)[/tex]

Remember this can be interpreted as:

[tex](x_1,y_1);(x_2,y_2)[/tex]

Looking at our x values first we have:

[tex]\frac{4+(-4)}{2}=\frac{0}{2}=0[/tex]

Looking at our y values we have:

[tex]\frac{-5+5}{2}=\frac{0}{2}=0[/tex]

So our midpoint would be the point [tex](0,0)[/tex]

Answer: i thini its 2

Step-by-step explanation:

The function g(x) is:

g(x) = Ix - 5I.

Therefore, the option A in the given question is correct.

When a function is transformed, the graph's curve either "moves to the left, right, up, or down," "expands or compresses," "reflects," or all three.

The function is made possible by the fundamental function f(x) and the constant

g(x) = f(x - k),

horizontally moving, the f(x) k unit coordinates may be drawn.

The shift's direction depends on the value of k. Specifically,

If k > 0, the basis graph shifts right by k units.

If k < 0, the base graph shifts k units to the left.

Given that the parent function is f(x) = IxI.

From the definition,

the transformed function is moved horizontally to 5 units to the right.

So, the function is g(x) = Ix - 5I.

Therefore, g(x) = Ix - 5I.

Answer:

B. Phone company B because the sample was not biased.

Step-by-step explanation:

While Phone company A had a higher satisfaction rate, 25 people that conducted this poll were in at least 1 commerical of the phone company's in the past 3 years. This means that their reflection of the company is biased (typically higher) and not completely based off of their performance but instead how cool it was to be in a commerical or how much they were paid. If the poll was a more random sample of just customers, it would be more believable data. On the other hand, while phone company B had a lower satisfaction rate and higher deviation, their statistics are more believable due to the random sampling of customers.

Answer:

B 45 degrees

Step-by-step explanation:

if AB and CA are = the M2 = 90 degrees

in an right triangle ware one angle is 90 degrees and one is 45 degrees the outer one will be 45 degrees  

the total of the angles in a triangle is 180 degrees so 180 - 90 = 90

90 - 45 = 45

so the remaining angle is 45.

the answer is 11/4

The unit rate of change between variables is the quotient between the difference between y-values and the difference between x-values

The unit rate of change is y = 2.25x

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the values of x be set A = { 2 , 3 , 4 }

Let the values of y be set B = { 4 1/2 , 6 3/4 , 9 }

So , the unit rate of change can be calculated by slope and linear equation of line

So , Slope m is

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

m = ( 6 3/4 - 4 1/2 ) / ( 3 - 2 )

m =  2.25

So , the equation will be y = mx

y = 2.25x

Therefore , the unit rate of change is y = 2.25x

Hence ,

The unit rate of change is y = 2.25x and the graph is shown below

Answer:

x = 4√2

Step-by-step explanation:

Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pythagorean theorem

To solve, we will follow the steps below:

using Pythagoras theorem

opposite² +  adjacent² = hypotenuse²

14² + y² = 18²

196 + y² = 324

subtract 196 from both-side of the equation

196 -196 + y² = 324-196

y² =128

Take the square root of both-side

√y² = √128

y =√128

y = √64×2

y =√64×√2

y = 8√2

x = half of y

x = y/2

x = 8√2  ÷  2

x = 4√2

Answer:

x = 5.6

Step-by-step explanation:

5x:8 = 7:2

First, find the relationship between 2 and 7.

2 x 3.5 = 7

Since the ratios are equal, this means:

8 x 3.5 = 5x

Solve algebraically. First simply 8 x 3.5

5x = 28

Divide both sides by 5

x = 5.6
