Answer: -$480

Step-by-step explanation:

The revenue us P*x

now, when P = $40, we have:

X = 14400 - 3*40^2 = 9600

then the revenue is:

9600*$40 = $384000

now, the price increaces by $2 so the new equation is:

X = 14400 - 3*42^2 = 9108

The revenue is:

9109*$42 = $382536

You can see that the revenua is smaller than before.

Now, if we want to calculate the rate of change when p = $40, we need to look at X'(40)

this is:

X´(p) = -3*2*p

then:

X'(40) = -3*2*40 = -120

Theh rate of change of the revenua will be:

X'(40)*$40 = -120*$40 = -$480

Your parents have a realized income of $1,046.78/every 2 weeks. How much should the monthly housing expense budget be to stay wi

IgorLugansk [536]

Answer with explanation:

Income earned by my parents in every two weeks = $ 1046.78

In two weeks there are 14 days, so income earned by my parents in 1 day

$=\frac{1046.78}{14}\\\\74.77$

Income of my parents after a month, if there are 30 days in a month = $74.77 × 30= $ 2243.10

We, will use , $\frac{28}{36}$ rule here , which states that , 28% of monthly income of my parents, should be used for monthly housing expenses ,and 36% of gross monthly income should be used for debt purposes.

28% of $2243.78

$=\frac{28}{100}*2243.78\\\\=\frac{62825.84}{100}\\\\=628.2584$

= $ 628.26 (Approx)

So,my parents, monthly housing expense should not exceed ≥ $ 628.26

How do I find the quotient 2/5 divide by 1/4

Artemon [7]

Answer:

A. $\frac{2}{5} \times 4$

Step-by-step explanation:

Given:

$\frac{2}{5} \div \frac{1}{4}$

To find the quotient, we would multiply the first fraction (⅖) by the reciprocal of the second fraction (reciprocal of ¼ = 4).

This, we would have:

$\frac{2}{5} \times 4$

$= \frac{8}{5}$

How do I graph y=2/3x-4

snow_lady [41]

Step-by-step explanation:

In that equation it tells you that your slope is 2/3. It also tells you that your y intercept is -4. (Remember slope is written in y=mx+b) So first you plot your y value. (Remember that y intercept is up and down and slope is rise/fall over run) So your first point should be located at -4. Now you can began putting in your slope. Since your slope is positive, go up two and go to the right 3 times (rise/run). That's how you graph your equation.
