<h2>Answer:</h2>
<h2>Explanation:</h2>
Given the equation expressed as:
First, we need to calculate the value of "x" from the given expression.
Step 1: Given the equation 2x + 5 = 8x
Step 2: Subtract 5 from both sides:
Step 3: Subtract 8x from both sides
Step 4: Divide both sides by -6
Step 5: Get the value of 12x. Substitute x = 5/6 into the expression to have:
Therefore the value of 12x is 10
Answer:
(i) 28. (ii) 34. (iii) 42.5
Step-by-step explanation:
<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>
Hi there! Look at the attachments along with my explanation. Before we are going to answer your problem, we need to know the basic Trigonometric Ratio first.
Now see my attachments. The first attachment is the original image from your problem.
The second attachment is when we draw to focus on angle H (in a better perspective)
The third attachment is when we draw to focus on angle G in a better perspective.
Now that we know tanA = opposite/adjacent
Define A = any angles.
Therefore,
tanH = 1/2
tanG = 2/1 = 2
