1. Determine the equation of the line tangent to the curve y = =18x - at the point (1, 215). 2. If the unit selling price p(x) and the quantity supplied x of a certain product is given by p(x) = x43* + 3, find the marginal revenue function R'(x). R' (x ) = 3. Given the demand equation x = 185e-P/$2, where p represents the price in dollars and x the number of units, determine the value of p where the elasticity of demand is unitary. p = dollars 4. Let ely - x6 = y5. Compute 5. The demand function for SkanDisc 2GB thumb drives is given by p = 4(x + 3) e-x/3 where p is the wholesale unit price in dollars and x is the quantity demanded each week, measured in units of a thousand. Compute the price, p, when x = 9. Do not round your answer. Price, P = dollars Use implicit differentiation to compute the rate of change of demand with respect to price, p, when x = 9. Do not round your answer. Rate of change of demand, x' = thousands of units per dollar Compute the elasticity of demand when x = 9. Do not round your answer. Elasticity of Demand = 6. Determine whether each statement is true or false. You have one submission for each statement. (a) The derivative of elk is equal to 3x. OTrue OFalse (b) The derivative of e* f(x) is equal to e* [f(x) + F'(x)]. OTrue OFalse
