Answer:
The amount of oil was decreasing at 69300 barrels, yearly
Step-by-step explanation:
Given
Required
At what rate did oil decrease when 600000 barrels remain
To do this, we make use of the following notations
t = Time
A = Amount left in the well
So:
Where k represents the constant of proportionality
Multiply both sides by dt/A
Integrate both sides
Make A, the subject
i.e. At initial
So, we have:
Substitute in
To solve for k;
i.e.
So:
Divide both sides by 1000000
Take natural logarithm (ln) of both sides
Solve for k
Recall that:
Where
= Rate
So, when
The rate is:
<em>Hence, the amount of oil was decreasing at 69300 barrels, yearly</em>
Answer:
Step-by-step explanation:
Since g(x)=0, you input 0 into every x
Which then becomes:
Take out the 0 and there's your answer
For this case we can solve the problem by means of the following rule of three:
100 $ --------------> 100%
x -------------------> 250%
From here, we clear the value of x.
We have then:
Rewriting we have:
Answer:
The price of a four star dinner today is $ 250.
So this equation will be
x^2 +y^2 = 16^2
