You need to multiply across so numerator times numerator and denominator times denominator!

Choose the kinds of symmetry the following figure has: point, line, plane, or none.

algol [13]

<h3>Answer: Choice A) None</h3>

Explanation:

Can we rotate the figure some angle smaller than 360 degrees and have it match up with its original image? The answer to that is "no". Any such rotation will change the image to something else. Therefore, this figure does not have any point symmetry (aka rotational symmetry).

Can we reflect one half of the figure over some line to get the other half? The answer here is also "no". The diagram has no reflectional symmetry either.

Plane symmetry is ruled out because that only applies to 3D settings.

Answer:

x = 19
x = 34
x = 39

Step-by-step explanation:

1. A right angle has a measure of 90°. The whole is the sum of the parts.

(2x +3)° +49° = 90°

2x +52 = 90 . . . . . . . . divide by °, collect terms

2x = 38 . . . . . . . . . . . . subtract 52

x = 19 . . . . . . . . divide by 2

2. A linear pair measures 180°. The whole is the sum of the parts.

(x -5)° +151° = 180°

x +146 = 180 . . . . . . . divide by °, collect terms

x = 34 . . . . . . . . .subtract 146

3. We presume this pair of angles is supposed to be supplementary. That is, their sum is 180°.

64° +(3x -1)° = 180°

3x +63 = 180 . . . . . . . divide by °, collect terms

3x = 117 . . . . . . . . subtract 63

x = 39 . . . . . divide by 3

Calculate had a net income of 8 million dollars in 2010, while a small competing company, Computate, had a net income of 3 milli

Lilit [14]

The question is an illustration of a linear function and an exponential function.

The given parameters are:

<u>Calculate Company</u>

Initial net income: $8 million

Rate: $0.5 million per year

<u>Computate Company</u>

Initial net income: $3 million

Rate: 20% each year

<h3>(a) Standard mathematical model</h3>

The model of calculate company is best represented using a linear function, while the computate is best modeled by an exponential function.

A linear function is represented as:

$y = mx + b$

Where:

m represents rate
b represents the initial value

An exponential function is represented as:

$y = a(1 + r)^x$

Where:

r represents rate
a represents the initial value

So, the functions are:

$y=8 + 0.5x$ --- calculate company

$y =3(1.2)^x$ --- computate company

See attachment for the graph of both functions

<h3>(b) Compare both functions</h3>

From the graph of both functions, we have the following comparison:

The calculate company has a higher y-intercept
The computate company follows a more realistic model

<h3>(c) The company to choose</h3>

In (b), we concluded that:

The computate company follows a more realistic model

Hence, it is better to invest in the computate company

<h3>(d) When both companies have the same net income</h3>

From the attached graph, both functions meet at approximately (8, 12)

This means that they have the same net income in 2018

The graphs do not meet again.

This means that, they would never have the same net income again
