  1. What is the value of sin(30°)?

    Answer: 1/2

    sin(30°) equals 1/2 by the standard 30-60-90 triangle.

  2. In a geometric sequence with first term 3 and ratio 2, what is the 4th term?

    Answer: 24

    aₙ = 3·2³ = 3·8 = 24.

  3. What is the average rate of change of f(x) = x² from x = 1 to x = 3?

    Answer: 4

    (f(3)-f(1))/(3-1) = (9-1)/2 = 4.

  4. Solve: 2ˣ = 16.

    Answer: 4

    16 = 2⁴, so x = 4.

  5. What is the equation of a circle with center (0, 0) and radius 5?

    Answer: x² + y² = 25

    Standard form gives x²+y²=r²=25.

  6. If two events are independent with P(A)=0.4 and P(B)=0.5, what is P(A and B)?

    Answer: 0.2

    For independent events, multiply: 0.4·0.5 = 0.2.

  7. What is the y-intercept of y = 3x - 7?

    Answer: -7

    In y=mx+b, b is the y-intercept, here -7.
