Answer:
So, solution of the differential equation is
Step-by-step explanation:
We have the given differential equation: y′′+4y=5xcos(2x)
We use the Method of Undetermined Coefficients.
We first solve the homogeneous differential equation y′′+4y=0.
It is a homogeneous solution:
Now, we finding a particular solution.
we get
So, solution of the differential equation is
2x^2 - 8 = 0
2x^2 = 8
x^2 = 8/2 = 4
x = sqrt(4) = 2 or -2
<u>Answer:</u>
"It is used when you solve an equation in algebra" is the untrue statement.
<u>Step-by-step explanation:</u>
"It is used when you solve an equation in algebra."
When you solve an algebra problem, you are not using deductive reasoning. You are using the information in front of you to correctly answer.
"It is used to make broad generalizations using specific observations."
This is exactly what deductive reasoning is, you are making generalizations and coming up with your own conclusions through observation.
"It is used to prove basic theorems."
This is also true, you can use deductive reasoning by using your specific observations and drawing conclusions to prove the theorems.
"It is used to prove that statements are true."
Using your own observations, you can draw your own conclusions to prove what you are saying is factual.
Answer: 1)
2) 55 points
Step-by-step explanation:
1) A= 8w + 18, w=1.25
A = 8(1.25) + 18
A = 10 + 18
A = 28ft^2
2) 25 points to start with, additional 5 points per magazine they sell, m = number of magazines they sell
total points = 25 + 5m
How many if they sell 6?
total = 25 + 5(6)
= 25 + 30
total = 55
