If <em>x</em>² + <em>y</em>² = 1, then <em>y</em> = ±√(1 - <em>x</em>²).
Let <em>f(x)</em> = |<em>x</em>| + |±√(1 - <em>x</em>²)| = |<em>x</em>| + √(1 - <em>x</em>²).
If <em>x</em> < 0, we have |<em>x</em>| = -<em>x</em> ; otherwise, if <em>x</em> ≥ 0, then |<em>x</em>| = <em>x</em>.
• Case 1: suppose <em>x</em> < 0. Then
<em>f(x)</em> = -<em>x</em> + √(1 - <em>x</em>²)
<em>f'(x)</em> = -1 - <em>x</em>/√(1 - <em>x</em>²) = 0 → <em>x</em> = -1/√2 → <em>y</em> = ±1/√2
• Case 2: suppose <em>x</em> ≥ 0. Then
<em>f(x)</em> = <em>x</em> + √(1 - <em>x</em>²)
<em>f'(x)</em> = 1 - <em>x</em>/√(1 - <em>x</em>²) = 0 → <em>x</em> = 1/√2 → <em>y</em> = ±1/√2
In either case, |<em>x</em>| = |<em>y</em>| = 1/√2, so the maximum value of their sum is 2/√2 = √2.
Answer:
190,208
Step-by-step explanation:
732,178 + 167 = 732,345
732,345 - 542,137 = 190,208
Since the details are not available, we have provided an overview of William's total fixed and variable expenses for the first year of college.
<h3>What are college costs?</h3>
There are five categories of college costs.
These college costs include tuition, room and board, books and supplies, personal expenses, and transportation.
Some of the college costs like tuition and room and board may be relatively fixed.
This leaves expenses like books and suppliers, personal expenses, and transportation relatively variable.
Thus, William needs to control his variable college costs so that they do not exceed the student loan.
