Find the marginal cost to Levi Strauss of producing 100 pairs of blue jeans. 1. marginal cost = $17 per pair 2. marginal cost = $16 per pair 3. marginal cost = $18 per pair 4. marginal cost = $14 per pair 5. marginal cost = $15 per pair 002 10.0 points TI has discovered that the total cost (in dollars) of producing x calculators per day is given by C ( x ) = 500 + 50 x- x 2 2 . Find the Marginal Cost to TI at a production level of x calculators. 1. Marginal Cost = C ( x ) = 50- 1 x 2. Marginal Cost = C ( x ) x 3. Marginal Cost = C ( x ) = 50 + 1 x 4. Marginal Cost = 50 + 1 2 x 5. Marginal Cost = 50- 1 2 x 6. Marginal Cost = C ( x + 1)- C ( x ) 003 10.0 points Find the derivative of f when f ( x ) = 3 x cos 6 x . 1. f ( x ) = 3 cos6 x + 18 x sin 3 x 2. f ( x ) = 3 cos6 x- 18 x sin 6 x 3. f ( x ) = 18 cos 6 x + 6 x sin 6 x 4. f ( x ) = 3 cos3 x- 3 x sin6 x 5. f ( x ) = 18 cos 6 x- 3 x sin 6 x 004 10.0 points Find the derivative of f ( x ) = 3 x sin 2 x + 3 2 cos 2 x . 1. f ( x ) = 6 x cos2 x 2. f ( x ) =- 6 x cos 2 x 3. f ( x ) = 6 cos2 x 4. f ( x ) = 6 x cos2 x + 6 sin2 x 5. f ( x ) = 6 x cos2 x- 6 sin2 x 005 10.0 points Find the equation of the tangent line to the graph of y 2- xy- 15 = 0 , at the point P = (2 , 5). 1. 7 y + 5 x = 25 2. 7 y = 5 x + 25 3. 2 y = 5 x spano velasco (ds28282) ReviewExam2 jouve (58275) 2 4. 8 y + 5 x = 30 5. 8 y = 5 x + 30 006 10.0 points Find the second derivative of f when f ( x ) = cos 2 x + 3 sin 2 x . 1. f ( x ) =- 2 cos 2 x 2. f ( x ) = 2 sin 2 x 3. f ( x ) = sin 2 x 4. f ( x ) = cos 2 x 5. f ( x ) = 2 cos 2 x 6. f ( x ) =- cos 2 x 007 10.0 points Determine f ( x ) when f ( x ) = sin 2 x- 3 cos x . 1. f ( x ) = 2 sin 2 x + 3 cos x 2. f ( x ) = 2 cos 2 x + 3 cos x 3. f ( x ) = 2 cos 2 x- 3 cos x 4. f ( x ) = sin 2 x- 3 sin x 5. f ( x ) = cos 2 x- 3 sin x 6. f ( x ) = cos 2 x + 3 cos x 008 10.0 points A point is moving on the graph of 3 x 3 + 5 y...
