According to a rule in geometry, the dimension of an object made up of n dimensions is n+1. For example a cube is 3d which is made up of squares which are 2d and a square is made up line segments which are 1d. So, as circle is made up of diameters which are 1d, it is 2d or second dimensional space. Hope you like it.

Which inequality will have a dashed boundary line with a shaded area above its graph? 7x − y ≤ 3 x − y ≤ 4 2x − 9y > 2 4x + 7

alexdok [17]

Above the graph

look at them

7x-y <span><</span>3
x-y<span><</span>4
2x-9y>2
4x+7y>3

dashed boundary line means it does't include htat means taat the symbol is < or >

cross out first 2

one way is to graph the lines as equations and shade accordingly

2x-9y>2
y<2/9x+2/9
shade on bottom

4x+7y>3
y>-7/4x+3/9
shade on top

aswer is 4x+7y>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
