1What is the completely factored form of 9x^2 - 25?
A.(3x - 5)(3x + 5)
B.(3x - 5)^2
C.(9x - 5)(x + 5)
D.(3x + 5)^2
Explanation: Write the expression as (3x)^2 - 5^2. The difference-of-squares identity a^2 - b^2 = (a - b)(a + b) then gives (3x - 5)(3x + 5).
2Solve 5(2x - 3) = 3(x + 2) + 7.
A.x = 4
B.x = 2
C.x = -2
D.x = 14/5
Explanation: Expand to obtain 10x - 15 = 3x + 13. Collecting terms gives 7x = 28, so x = 4; substituting yields 25 on both sides.
3What is the distance between A(1, -2) and B(4, 2)?
A.5 units
B.7 units
C.sqrt(7) units
D.25 units
Explanation: The coordinate differences are 3 and 4. The distance is sqrt(3^2 + 4^2) = sqrt(25) = 5 units.
4What is tan(45 degrees) + cos(60 degrees)?
A.3/2
B.1/2
C.1 + sqrt(3)/2
D.2
Explanation: The special-angle values are tan(45 degrees) = 1 and cos(60 degrees) = 1/2. Their sum is 3/2.
5What is the real domain of f(x) = 1/(2x - 10)?
A.All real numbers except 5
B.All real numbers greater than 5
C.All real numbers except -5
D.All real numbers
Explanation: A denominator cannot equal zero. Since 2x - 10 = 0 at x = 5, that is the only excluded real number.
6Three adult passes and four student passes cost USD 31 in total. An adult pass costs USD 1 more than a student pass. What are the two prices?
A.Adult USD 5; student USD 4
B.Adult USD 4; student USD 5
C.Adult USD 7; student USD 2
D.Adult USD 6; student USD 3
Explanation: Let s be the student price, so the adult price is s + 1. Then 3(s + 1) + 4s = 31 gives 7s = 28, hence student USD 4 and adult USD 5.
7What are the real roots of 2x^2 - 5x - 3 = 0?
A.x = 3 and x = -1/2
B.x = -3 and x = 1/2
C.x = 1 and x = -3/2
D.x = 5/2 and x = -3
Explanation: The polynomial factors as (2x + 1)(x - 3). Setting each factor to zero gives x = -1/2 and x = 3.
8Which parabola has vertex (0,0) and focus (0,3)?
A.x^2 = 12y
B.y^2 = 12x
C.x^2 = 3y
D.y^2 = 3x
Explanation: A focus at (0,p) gives a vertical parabola x^2 = 4py. Here p = 3, so x^2 = 12y.
9Given f(x) = 2x + 3 and g(x) = x^2 - 1, what is g(f(1))?
A.24
B.3
C.1
D.8
Explanation: First calculate f(1) = 5. Then use that output as the input to g: g(5) = 25 - 1 = 24.
10Simplify (1 - sin^2(theta))/cos(theta), assuming cos(theta) is nonzero.
A.cos(theta)
B.sin(theta)
C.sec(theta)
D.tan(theta)
Explanation: The Pythagorean identity gives 1 - sin^2(theta) = cos^2(theta). Dividing by the nonzero cos(theta) leaves cos(theta).
