This problem is based on Exercise 8 from Active Calculus, Section 1.5. The value, V, of a particular automobile (in dollars) depends on the number of miles, m the car has been driven, according to the function V = h(m). Consider h' (15000). Based on the given information, select the best statement about the units of h' (15000). O h' (15000) has units of years per mile. O h' (15000) has units of miles per dollar. O h' (15000) has units of dollars per mile. O h' (15000) has units of miles per year.Consider g (@) = x2 . sinc. Let a =4.T. Find g (a). Round your final answer to the nearest tenth.Problem: Find the critical numbers of the function. g (0) = 40 - tan 0 that lie between 0 and 27. Solution Steps: 1. Set g' (0) equal to 0. 2. Use difference of squares factoring. 3. Set each factor equal to 0. 4. Recall that sec 0 = cos 8 5. Consult a table, diagram, or calculator to find values of cos 0 for 0 between 0 and 21. The answer to the question is 0 = 2n Am a 3' 3 : 3 , and 5x Question for you: What does step 2 look like? O (20 + sec 0) (20 - sec 0) = 0 O (4 + sec @) (1 - sec #) = 0 O (2 + sec 0) (2 - sec #) = 0On the domain -2
