Answer:
(See attached graph)
Step-by-step explanation:
To solve a second-order homogeneous differential equation, we need to substitute each term with the auxiliary equation where the values of
are the roots:
Since the values of are equal real roots, then the general solution is
.
Thus, the general solution for our given differential equation is .
To account for both initial conditions, take the derivative of , thus,
Now, we can create our system of equations given our initial conditions:
We then solve the system of equations, which becomes easy since we already know that :
Thus, our final solution is:

Step-by-step explanation:
The red line represents the line for women, while the blue line represents the line for men.
Age 45 is the middle of 40 and 45 on the x-axis.
The average number of awakenings during the night for 45 -year-old men ≈ 5
The average number of awakenings during the night for 45 -year-old women = 3
The difference = 5 - 3 = 2 times during the night.
