Okay so for Mike, he has $22 in his account.
He deposits $11.50 in it each week, and they want to know how much he has in 12 weeks.
First, multiply $11.50 * 12, which is $138. Then add the $22 that's already in the account, which brings him to $160.
Now for Tim,
He has $218 and withdraws $13 every week.
13 * 12 = 156
Now subtract 218 and 156
218 - 156 = 62
So at the end of 12 weeks, Mike has $160 dollars in his account, and Tim has $62 in his account.
David's total income is ($8/hr)x + ($11/hr)y.
This problem requires us to write and solve an inequality:
8x + 11(15)<$200
Solving for x: 8x < $200-$165, or 8x < $35. Strictly speaking, x = 4.375 hrs, but if we assume that David must work an integer # of hours, then x=5 full hours.
The algebraic expression for the word phrase "the product of a number and 3" as a variable expression is 3z
<h3>How to write an algebraic expression for the word phrase "the product of a number and 3" as a variable expression?</h3>
The word phrase is given as:
"the product of a number and 3"
Represent the number with z
So, the word phrase can be rewritten as:
"the product of a number z and 3"
The product of a number z and 3 is represented as:
z * 3
When evaluated,, the expression becomes
z * 3 = 3z
Hence, the algebraic expression for the word phrase "the product of a number and 3" as a variable expression is 3z

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
