katen-ka-za [31]

Pam and her brother both open savings accounts. each begin with a balance of $0. For every $2 is that Pam saves in her account her brother saves $5 in his account

P:bro=2:5
when P=40 what is bro?

2/5=40/b
times 5b both sides
2b=200
divide 2
b=100
bro has $100
not sure what tape diagram is

Which number is in the domain of f(x)

MAXImum [283]

We should first find where the graph doesn't exist, which would be where the denominator is equal to 0 or the formula under the radical is negative. So we can write the equation x-3≤0 to find where the graph can't exist
x-3≤0
x≤3

So this means that no x values less than or equal to 3 can exist on this graph. So the only choice that isn't less than or equal to 3 is choice 2 (7)

Hope this helps

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
