Answer:
Step-by-step explanation:
Answer:
Therefore the auxiliary solution is
Therefore are linearly independent
Step-by-step explanation:
Given, the differential equation is
y"-y'-20 y=0
Let be the solution of the above differential equation.
y'= and
Then the above differential equation becomes
If two roots of m are real and distinct then the auxiliary solution is
[where a and b are two roots of m]
Therefore the auxiliary solution is
Wronskian
≠0
Therefore are linearly independent.[ ∵W≠0]
Answer:
= 9y^4 -6y^3 -17y^2 -18y -10
Step-by-step explanation:
(3y^2 + 2y + 2) x (3y^2 – 4y – 5)
9y^4 - 12y^3 - 15y^2 + 6y^3 -8y^2 -10y +6y^2 -8y -10
= 9y^4 -6y^3 -17y^2 -18y -10
The <em><u>correct answer</u></em> is:
A box and whisker plot
Explanation:
A box and whisker plot, or a box plot, displays what is called the "five number summary." This includes:
Median; LQ (lower quartile, or the median of the lower half of data); UQ (upper quartile, or the median of the upper half of data); lowest value; and highest value.
This will show the spread of data, and the mean can easily be added to this diagram.
You could use a simple calculator it's only 10.
