Answer:

Step-by-step explanation:

I graphed this on my calculator to get the region of feasibility. You should learn how to use your calculator to help you do things like this. You should know by now how to graph by hand, which is tedious, so now it's time to use your calculator to sweat the small stuff and learn to do some useful things.

When you graph this inequality on your calculator, you can see the points of intersection which in turn translate to the vertices of the feasible region. They are located at:

(-14, -6), (-9, -11), (6, 4)

You could then use those vertices to maximize the profit equation or production equation or whatever it is this system pertains to.

Carlos is draining an aquarium. The graph shows the amount of water ( in liters) in the aquarium versus time ( in minutes

olya-2409 [2.1K]

Using a linear function, we have that:

a) The amount of water in the aquarium at 0 minutes is of 300 liters.

b) As time increases, the amount of water decreases at a rate of 60 liters per minute.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = ax + b

In which:

a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, we have that the y-intercept is of 300, hence the amount of water in the aquarium at 0 minutes is of 300 liters.

The amount <u>decreases 60 liters in a minute,</u> hence:

As time increases, the amount of water decreases at a rate of 60 liters per minute.

Find the break - even points for company X, which sells all it produces, if the variable cost per unit is $3, fixed costs are $2

ohaa [14]

Given:

The variable cost per unit is $3, fixed costs are $2.

The revenue function is:

$Y_{TR}=5\sqrt{q}$

where q is the number of thousands of units of output produced.

To find:

The break - even points for company X.

Solution:

The variable cost per unit is $3, fixed costs are $2.

So, the cost function is:

Total cost = Fixed cost + Variable cost × Quantity

$Y_{TC}=2+3q$

The revenue function is:

$Y_{TR}=5\sqrt{q}$

At break - even points the profit is zero. It means the cost and revenue are equal.

$Y_{TC}=Y_{TR}$

$2+3q=5\sqrt{q}$

Squaring both sides, we get

$(2+3q)^2=(5\sqrt{q})^2$

$2^2+2(2)(3q)+(3q)^2=25q$

$4+12q+9q^2-25q=0$

$4-13q+9q^2=0$

Splitting the middle term, we get

$4-4q-9q+9q^2=0$

$4(1-q)-9q(1+q)=0$

$(4-9q)(1-q)=0$

Using zero product property, we get

$4-9q=0$ and $1-q=0$

$q=\dfrac{4}{9}$ and $q=1$

$q\approx 0.444$ and $q=1$

Therefore, the break even points are 0.444 and 1.
