A gas in a container changes its volume according to the law, PV = 3 600, where P is the number of units of pressure and V is the number of units of the volume. Given that P is increasing at a rate of 20 units per second at the instant when P = 40, calculate the rate of change of volume at this instant. It would be better if Differentiation is used.

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

you first to choose the points and then move from then as the slope you have
