Unformatted text preview: nanni (arn437) – Assignment 5 – guntel – (54940) 1 This print-out should have 6 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Determine the integral I = integraldisplay (1 + 2 x − 9 4 ) dx . 1. I = x − 8 9 x 5 4 + C 2. I = x − 8 5 x − 5 4 + C correct 3. I = 1 − 8 9 x − 5 4 + C 4. I = x − 8 9 x − 5 4 5. I = 1 − 8 5 x 5 4 Explanation: Since integraldisplay x r dx = x r +1 r + 1 + C holds for all r negationslash = − 1, integraldisplay (1 + 2 x − 9 4 ) dx = integraldisplay dx + 2 integraldisplay x − 9 4 dx = x − 8 5 x − 5 4 + C with C an arbitrary constant. 002 10.0 points Determine the integral I = integraldisplay x 4 + 3 x 2 + 3 x 2 dx. 1. I = x 3 + 3 x + 3 x + C 2. I = 1 3 x 3 − 3 x − 6 x 3. I = 1 3 x 3 + 3 x − 3 x + C correct 4. I = 1 3 x 3 + 3 x − 3 x 5. I = 1 3 x 3 − 3 x − 6 x + C 6. I = x 3 + 3 x + 3 x Explanation: After dividing x 4 + 3 x 2 + 3 x 2 = x...
