$\dfrac{1}{x-2}-\dfrac{1}{x+2}=\dfrac{x+2}{(x-2)(x+2)}-\dfrac{x-2}{(x-2)(x+2)}\\\\=\dfrac{(x+2)-(x-2)}{(x-2)(x+2)}=\dfrac{x+2-x+2}{(x-2)(x+2)}=\dfrac{4}{x^2-4}\to(D)$

Used: $a^2-b^2=(a-b)(a+b)$

Answer: (D)=(4/x^(2)-4)

Plot a point on the line with the Y- coordinate y=4

Dima020 [189]

ANSWER :

(1, 4)

EXPLANATION :

From the problem, we have the equation of the line :

$2x-2=0$

Which can be reduced as :

$\begin{gathered} 2x-2=0 \\ 2x=2 \\ x=\frac{2}{2} \\ \\ x=1 \end{gathered}$

Then the graph of the line will be :

We need to plot a point that is on the line with a y-coordinate of 4.

That will be :

The point on the line will be (1, 4)

Oil is pumped continuously from a well at a rate proportional to the amount of oil left in the well. Initially there were 3 mill

abruzzese [7]

Answer:

V' = -0.11552 *V\\= -0.11552(1.8)\\ \\=-0.20794 million per year

Step-by-step explanation:

Given that oil is pumped continuously from a well at a rate proportional to the amount of oil left in the well. Initially there were 3 million barrels of oil in the well; six years later 1,500,000 barrels remain.

i.e. if V stands for volume of oil, then

$V' =kV\\dv/V= kdt\\ln V = kt+C\\V = Ae^{kt}$
