2. Warm Up 4/24/15 1.Identify the roots of the equation. State the multiplicity at each root. (Graph to find a root, then use synthetic division.) x 4 – 8x 3 + 24x 2 – 32x + 16 = 0 2.Find the mean, median, mode, and standard deviation for the data set: 4, 16, 25, 9, 36, 49

3. Warm Up 4/27/15 3. Find the mean absolute deviation of the data set. Round the mean and answer to the nearest tenth. 4, 16, 25, 9, 36, 49 4. Multiply: (x – (2 + i))(x – (2 – i))

4. Warm Up 4/28/15 5.Use the quadratic formula to solve: x 2 – 10x + 11 - b + √b 2 – 4ac 2a 6. Factor 6x 2 + 11x - 10

5. Warm Up 4/20/15 7.If the area of a rectangle is 3x 3 – 11x 2 – 56x – 48 and the length is 3x + 4, what is the width? 8.Find the first 5 terms of the sequence: a n = (2) n – 1 + 8

6. Warm Up 5/1/15 9.Divide the rational expressions: 10. Find the intervals of increase and decrease for the polynomial: f(x) = 2x 3 – 12x + 6 ÷
