Answer:

the slope of this graph is $-\frac{3}1}$

Step-by-step explanation:

You can find the slope by choosing any two ordered pairs in this case I choose (2,-4) and (-1,1). The you find the run and rise. Slope= $\frac{rise}{run}$ , the run was 3 up and the run was 1. And it is negative because it is going down to the right.

Answer:

-3/1

Step-by-step explanation:

The slope can be found by putting the rise over the run.

Pick 2 points on the graph that intercept the line.

I'll pick (0,2), and (1,-1)

Look at the rise.(How many places it goes up or down)

The rise vertical distance(rise), between the two points is -3.

Now look at the run(the horizontal distance.) It's 1.

Rise/Run = -3/1 AKA -3

The gas law for an ideal gas at absolute temperature T (in kelvins), pressure P (in atmospheres), and volume V (in liters) is PV

JulijaS [17]

Answer:

$\frac{dT}{dt}=3.78^{\circ}K/min$

Step-by-step explanation:

We have to calculate the time derivative of T=PV/nR with P and V variable and n and R constants. This is:

$\frac{dT}{dt} =\frac{d\frac{PV}{nR}}{dt}=\frac{1}{nR}\frac{d(PV)}{dt}$

What we have to do is the derivative of a product:

$\frac{d(PV)}{dt}=P\frac{dV}{dt}+V\frac{dP}{dt}$

Substituting, we have:

$\frac{dT}{dt} =\frac{P\frac{dV}{dt}+V\frac{dP}{dt}}{nR}$

where all these values are given since the time derivatives of P and V are their variation rate, using minutes.

We then substitute everything, noticing that already everything is in the same system of units so they cancel out:

$\frac{dT}{dt}=\frac{P\frac{dV}{dt}+V\frac{dP}{dt}}{nR}=\frac{(8atm)(0.16L/min)+(13L)(0.14atm/min)}{(10mol)(0.0821Latm/mol^{\circ}K)}$

And then just calculate:

$\frac{dT}{dt}=3.78^{\circ}K/min$

zhenek [66]

Answer:

R(x) = -0.05x^2 +80x

Step-by-step explanation:

Given the two points (x, p), the equation for the price associated with a given demand quantity can be written using the 2-point form:

p = (p2 -p1)/(x2 -x1)(x -x1) +p1

p = (40 -50)/(800 -600)(x -600) +50

p = -0.05x +80 . . . . simplify

Then the revenue equation is ...

R(x) = xp

R(x) = -0.05x^2 +80x
