The property which states that multiplying a number by 1 does not change the number's value is the identity property. <span>Adding zero to a number does not change the number's value is the zero property, but some people do also call it the identity property of addition. Hope this helped!</span>
Answer:
x=(-1+-√ 10)/3
Step-by-step explanation:
number in the square root is the discriminant
Answer:
50
Step-by-step explanation:

again,850/17=50
Answer:
4
Step-by-step explanation:
because variable is independent
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.
