She can make 22 patties since 5 1/2 divided by 1/4 is 22
<span>3x''+3x'+7x = 9sin 3t - to begin
then </span>Use the method of undetermined coefficients
Then you need to find <span><span>x′p</span> and <span>x′′p and sub them into equation, that will help you to solve A and B.
</span></span>
And finally you will have this :
<span><span><span>3<span>x′′</span>+3<span>x′</span>+7x=9sin(3t)</span><span>[−27Asin(3t)−27Bcos(3t)]+[9Acos(3t)−9Bsin(3t)]+[7Asin(3t)+7Bcos(3t)]</span><span>=9sin(3t)</span><span>(−20A+9B)sin(3t)+(−20B+9A)cos(3t)=9sin(3t)</span></span></span>
Answer:
The first answer in the second row
Step-by-step explanation:
Answer:
x = -6x - 12
Step-by-step explanation:
f(x) = -6 ( x + 2 )
f(x) = -6x - 12
y = -6x - 12 (switch y and x each other)
x = -6y - 12
I hope this helps!
