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
To find A and k
V(0) = A = 3 million
Hence V =
V(6) = 1.5
i.e.
a) Using the above value of k , we have
million per year.
We have that
y=x²<span>+5x+3
y=</span>√(<span>2x+5)
using a graph tool
see the attached figure
the solution is
x=-0.175
y=2.156
therefore
the answer is the option

The value of x in the equation (x - 5)² = 25 is 10.
<h3>How to solve an equation?</h3>(x - 5)² = 25
Take the square root of both sides
Therefore,
√(x - 5)² = √25
x - 5 = 5
add 5 to both sides
x - 5 + 5 = 5 + 5
x = 10
