Answer:
awnser is A
Step-by-step explanation:
Multiply all sides by 2 then add then up and you get 432.
It is a terminating decimal because the answer is -25.6
8.11 x 10^-3
435
34 x 10^2
1.2 x 10^7
-10. It is negative, so it it not a whole number. It can be written as a ratio, so it is rational.
Hope that helped you!
Answer:
-10/3, 10/3
Step-by-step explanation:
<em>(In this answer I will use y' to denote the derivative of y with respect to t. You shouldn't normally do this because y' normally means the derivative of y with respect to x but I'll be a bit messy for this case)</em>
First calculate the derivatives:
.
Then plug the derivtes y'' and y into the equation:
Solve the equation for k:
So then we have that satisfies the differential equation when or when (or both). The solutions to these equations are:
I understand that looks a bit complicated and I doubt you would have to give your answers in terms of t so if it asks for a separated list of answers I would go for:
k = -10/3, 10/3.
