Answer:
cos3x
Step-by-step explanation:
y" - y' + 9y = 3 sin 3x
here 
will be replaced by 
where 
is coefficient of x
y=cos3x
hence Particular solution is cos3x
3/4 = 30/40 so therefor b 33/40 is greater than 30/40 is correct
I need to see the picture so I can answer
The RF is 9. You could go to Easycalculations.com/statics/cumulative/relativefrequency to double check :)
Answer:
P(1.5, 3.5)
Step-by-step explanation:
We need to find the average of the x and y coordinates. We do this by adding the two values, then dividing by two:
P(x1 + x2/ 2, y1 + y2/2) = P(1 + 2/ 2, 2 + 5/ 2) = P(3/2, 7/2) = P(1.5, 3.5)
These are our coordinates!
