- The cost in dollars of making x items is given by the function Cx)=10x+500. a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item. b.What is the cost of making 25 items? c.Suppose the maximum cost allowed is SI500. What are the domain and range of the cost function, C(x) ?arrow_forwardWhen a certain drug is taken orally, the concentration of the drug in the patient's bloodstream After t minutes is given by C(t)=0.06t0.0002t2 where 0t240 and concentration is measured in mg/L .When is the maximum serum concentration reached, and what is that maximum concentration?arrow_forwardA soda can has a volume of 25 cubic inches. Let x denote its radius and h its height, both in inches. a. Using the fact that the volume of the can is 25 cubic inches, express h in terms of x. b. Express the total surface area S of the can in terms of x.arrow_forward
- The kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?arrow_forward√ (2+ ln x)³ dx Xarrow_forward5arrow_forward
- find Zrr and Zss for function Z(r,s)=ln(2r+3s)arrow_forward3 X 4. f.x²¹ - 2x² - 6x +1 2 x² - 2x-8 dxarrow_forwardWe have found that the volume of solution in the tank at time t is given by 400 + t. Let A(t) be the amount of salt in the tank at timet, measured in pounds. Then the concentration of salt at time t is given by the ratioA(E) 400 +t Recall that solution is pumped out at a rate of 2 gal/min. Therefore, the rate (in Ib/min) that salt is removed from the tank is as follows. Rout = (concentration of salt removed) · (2 gal/min) - ( Ib/gal : (2 gal/min) A(t) %3D 400 + t Ib/min 400+tarrow_forward
