I think A) 117 km2 should be correct
Answer:
minimum
Step-by-step explanation:
Given a quadratic in standard form f(x) = ax² + bx + c ( a ≠ 0 )
• If a > 0 then vertex is a minimum
• If a < 0 then vertex is a maximum
f(x) = 3x² + 5x + 2 ← is in standard form
with a = 3
Since a > 0 then vertex is a minimum
Yes because if you graph it, it will pass the vertical line test
Use the inverse sine function on a calculator.
arcsin (0.88) = 1.08 radians
Selection B is appropriate.
