What is the vertex of the parabola y = (x - 3)² + 5?
Answer: (3, 5)
In vertex form y = (x - h)² + k, the vertex is (h, k) = (3, 5).
Which of the following is a rational number?
Answer: √9
√9 = 3, which is an integer and therefore rational; the others are irrational.
Evaluate the arithmetic sequence term: a₁ = 7, d = 4, find a₆.
Answer: 27
aₙ = a₁ + (n-1)d → a₆ = 7 + 5(4) = 7 + 20 = 27.
What is the result of (2 + 3i)(2 - 3i)?
Answer: 13
(2+3i)(2-3i) = 4 - 9i² = 4 - 9(-1) = 13.
Which of the following correctly describes an exponential function?
Answer: f(x) = 2ˣ
An exponential function has the variable in the exponent, as in f(x) = 2ˣ.
Solve the system: x + y = 10 and x - y = 4.
Answer: x = 7, y = 3
Adding the equations: 2x = 14 → x = 7; substituting: y = 10 - 7 = 3.
What is the value of tan(45°)?
Answer: 1
tan(45°) = sin(45°)/cos(45°) = (√2/2)/(√2/2) = 1.
