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
Answer:
The measure of angle 7 is 34 degrees.
Step-by-step explanation:
Since a || b, angles 3 and 7 are corresponding angles which are congruent. Therefore, since the measure of angle 3 is 34 degrees, the measure of angle 7 is 34 degrees.

Answer: 33%</h3>
===========================================================
Explanation:
1/3 converts to the decimal form 0.333333... where the 3's go on forever
5/3 is a similar story but 5/3 = 1.666666.... where the '6's go on forever
The notation
indicates that the 6's go on forever.
So, 
The horizontal bar tells us which digits repeat. As another example, 
The three dots just mean "keep this pattern going forever".
----------
Everything mentioned so far has the decimal portions go on forever repeating some pattern over and over.
The only one that doesn't do this is 33% which converts to the decimal form 0.33
The value 0.33 is considered a terminating decimal since "terminate" means "stop". So this is the value that doesn't fit in with the other three items mentioned.
Answer: 3
Step-by-step explanation:
Since the denominator of the two fractions are already the same, we do not have to alter the fractions at all
Because the denominators are the same, all we have to worry about is the numerator, so take 67 and subtract 43 from it to get 24

As you know, 24/8 = 3, and that would be your final answer
