    Evaluate A + B C March Regional Algebra 2 Team: Question 6 Let A = the second term of a harmonic sequence if: the first term of the harmonic

    sequence is 12 the third term is 18 and the fourth term is

    111

    Let B = the numerical value of 7log21 2( ) 3log213( ) 3log218( ) 7log2112( )

    Evaluate 2A + B March Regional Algebra 2 Team: Question 7

    Let A = the value of 37 a + b( ) if 4 + 9i7+ 5i is written in the form a + bi Let B = the sum of the squares of the roots of the following function: f x( ) = x2 + 6x + 7 Let C = the number of distinguishable ways the letters of stanfordrocks can be arranged Let D = the number of distinguishable ways twelve different people can sit around a perfectly circular table.

    Evaluate A B + 2CD March Regional Algebra 2 Team: Question 8 In Facetiousland, the world is flat and everything can be mapped perfectly with a Cartesian coordinate system. Dianne and Richard are fleeing from the FBI in Facetiousland; in order to avoid detection, they must make stops at (1, 0), (-1, 16), and (2, 1). After carefully examining a secret map, Richard discovers PharmaExpress, a parabolic road that passes through all three points.

  • What is the parabolic function that passes through all three these points? Express your answer in the following form: y = Ax2 + Bx +C March Regional Algebra 2 Team: Question 9

    Let A = the solution set to: x + 4x 2 5 Let B = the solution set to: x3 4x2 4x + 5 3x 5 For your final answer, evaluate the sum of the greatest integer in A with the smallest negative integer in B March Regional Algebra 2 Team: Question 10 The expression 12 + 4 8 can be written in the form A + B C where everything is in simplest radical form and A, B, and C are whole numbers.

    Let D = 6 0 03 2 15 4 1

Grant has 200 feet of magic fencing to build a boundary for the garden; furthermore, he intends to use an infinite strip of the Everglades as one side of the gardens boundary. By the laws and regulations of magic, Grant must use all

  • of his fencing, the garden must be a rectangle, and the area of the garden must be as large as possible. Given these conditions, what will be the area of Grants enchanted garden in square feet? March Regional Algebra 2 Team: Question 13 Let A = the base ten representation of 7618 Let B = the base ten representation of 2145 + 3025 Evaluate the sum of the digits of (A + B) March Regional Algebra 2 Team: Question 14
