There is only one number that is equal to the absolute value of 15.
That number is 15.
But wait !
There are two different numbers WHOSE ABSOLUTE VALUES
are both 15.
Those numbers are 15 and -15 .
A.23/6
b.23/8
c.26/5
d.64/9
First, we need to solve the differential equation.
This a separable ODE. We can rewrite it like this:
Now we integrate both sides.
We get:
When we solve for y we get our solution:
To find out if we have any horizontal asymptotes we must find the limits as x goes to infinity and minus infinity.
It is easy to see that when x goes to minus infinity our function goes to zero.
When x goes to plus infinity we have the following:
When you are calculating limits like this you always look at the fastest growing function in denominator and numerator and then act like they are constants.
So our asymptote is at y=8.
