- A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.7 gallons. What is the average rate of flow of the gasoline into the gas tank?arrow_forwardFind the average rate of change of f(x)=x2x on the interval [1,9] .arrow_forwardThe resistance of a copper wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. A copper wire with a diameter of 0.0126inch has a resistance of 64.9ohms per thousand feet. What length of 0.0201-inch-diameter copper wire will produce a resistance of 33.5ohms?arrow_forward
- 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_forwardy -1.0 -0.5 0.5 1.0 1.5 2.0 f(x, у) dAarrow_forwardAssume a box has a square base and the length of a side of the base is equal to twice the height of the box. a. If the height is 6 inches, what are the dimensions of the base? The dimensions of the base are inches X inches = square inches. b. Write functions for the surface area and the volume that are dependent on the height, h. S(h) = nh" square inches, where n = and m = %3D V(h) = ph° cubic inches where p = and g = %3D c. If the volume has increased by a factor of 27, what has happened to the height? The new height is times the original height. d. As the height increases, what will happen to the ratio of (surface area)/volume? The ratio will not chänge e Textbook Increase decreasearrow_forward
- Find for y= =csc(x) %3D 2arrow_forwardGive the slope and the y intercept of the line – 10x + ly – 5 = 0. Slope = y intercept = (0, Enter your answers as integers or as reduced fractions in the form A/B.arrow_forwardRange and height versus speeda. Show that doubling a projectile’s initial speed at a given launch angle multiplies its range by 4.b. By about what percentage should you increase the initial speed to double the height and range?arrow_forward
