A company determines the demand, in hundreds, for their novelty t-shirts to be q = 0(1)) = 400 - 102, where p is the price for one shirt. a) Find the elasticity of demand E. b) If the price is $5 per shirt, calculate the elasticity. Is the demand elastic or inelastic? Will an increase in price result in an increase in total revenue? Find the equation of the tangent line to the curve whose equation is given by y3 +2x2y8y :1:3 + 19whenx = 2. A car leaves a given point and travels north at 30 mph. Another car leaves the same point at the same time and travels west at 40 mph. At what rate is the distance between the two cars changing at the instant when the cars have traveled 2 DE? (Hint: draw a picture showing the two cars leaving from the intersection and the distance between them (a straight line). Then label the distances the cars have traveled with variables)
