Answer:
a=2, b=5
Step-by-step explanation:
Let
n -----> the denominator
we have

Solve for n
That means -----> isolate the variable n
Multiply by n both sides

Divide by 3.5*10^4 both sides

therefore
a=2, b=5
Answer:
Decreases
Step-by-step explanation:
We need to determine the integral of the DE;



We can solve this by integration by parts on the left side. We expand the fraction 1/P²:

let





Substitute u in:

Therefore the equation is:

We simplify:


As t increases to infinity P will decrease
Answer:
$39.6
Step-by-step explanation:
5.5 times 7.20 = $39.6
To find a number between both decimals, what you can do is take the average of both numbers.
We have then:

Rewriting we have:

Therefore, the decimal obtained is a number between 0.4 and 0.5
Answer:
a decimal between 0.4 and 0.5 is:

Answer:
(8,4)
Step-by-step explanation:
y and -y cancels out leaving you with "12x=96"
that simplifies to "x=8"
Then you substitute 8 into the "x" from either equation and y should equal 4
