How do you do this question?

Answer:

The required relation is,

$\frac {dV}{dt}$ = $c{\frac{dT}{dt}}$

Step-by-step explanation:

We know that for a certain amount of dry gas when the pressure is kept constant it's volume V and temperature T is related by the function,

V = cT -----------------------(1) [where "c" is a constant]

So, in that case rate of change of volume(V) with respect to time (t),

= $\frac {dV}{dt}$

will be equal to ,

$c{\frac{dT}{dt}}$

where $\frac {dT}{dt}$ is equal to rate of change of temperature (T) with respect to time (t) and c is the constant stated before.

So, the required relation is,

$\frac {dV}{dt}$ = $c{\frac{dT}{dt}}$

Answer:

$d=10$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Used to find the distance between 2 points.

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

$d=\sqrt{(7-1)^2+(-7-1)^2}$

$d=\sqrt{(6)^2+(-8)^2}$

$d=\sqrt{36+64}$

$d=\sqrt{100}$

$d=10$
