Answer:
The expression related pounds of each kind of meat you could buy at the store with $30 is .
Step-by-step explanation:
Given:
Total Money = $30
Cost of Roast beef per pound = $4.29
Cost of Turkey per pound = $3.99
Let Number of pounds Roast beef be x
Also Let Number of pounds Turkey be y
Hence the expression related to to the pounds of each kind of meat you could buy at the store with $30 is given by.
Total Money is equal to Cost of Roast beef per pound multiplied by Number of pounds Roast beef plus Cost of Turkey per pound multiplied by Number of pounds Turkey.
The mathematical form for above statement can be written as;
Hence the expression related pounds of each kind of meat you could buy at the store with $30 is .
When integrating, u-substitution is used to make things easier to work out. In u-substitution, the "u" is generally determined if its derivative is in the expression. That way when integrating with respect to "u", you can just replace the derivative of the u with "du" and easily integrate.
For this question, it would be easiest to let:
Let's take the derivative of u and see if we can work something out:
We have an x² in the integral expression, and therefore, it's valid for us to let u = 2x³. Thus, your answer is A.
