. A mining company has two mines. One day's operation at mine #1 producesore that contains 40 metric tons of copper and 600 kilograms of silver, whileone day's operation of mine#2 produces ore that contains 50 metric tons of50copper and 580 kilograms of silver. Let v₁ = [400] and v₂ = [5]. Thenv₁ and 1₂ represent the "output per day" of mine #1 and mine#2,respectively.

A manufacturer of two products (Widgets and Gadgets) makes a profit of $130 for each widget sold and $100 for each gadget sold. However, production of these products generates hazardous waste charges at the rate of 1w2 (where Wis the number of Widgets produced) and 1263 (where G is the number of Gadgets produced). The manufacturer has ample supplies of all raw materials and can sell all the Widgets and Gadgets it produces. The firm has sufficient capacity to produce any realistic quantity of both products. What is the optimal quantity of each product to produce? (Round your answers to 1 decimal place.) Widgets and Gadgets What is the maximum profit the manufacturer can earn? (Round your answer to 2 decimal places.) Maximum profit

In 2017 the price of a particular earlier model car was about $15,905 with a depreciation of about $1,231 per year. A student had $500 in 2017 and saves $1,700 each year. a) Let H(t) be the value, in dollars, of the desired car t in years since 2017. Let S(t) be the student's total savings, in dollars, t years since 2017. Find equations of H and S. b) Set up an equation to predict when the student will be able to buy the car using cash from his savings. State the answer in terms of the year he can buy the car. c) Now assume that the student earns intrest on his savings. Is your answer from part (b) an underestimate or overestimate? Explain.
A company produces two types of hand soaps: a solid and a liquid soap. The cost of production for a solid soap is 10 cents per soap and 20 cents for the liquid soap. The company developed a model that predicts how many units x1 (of the solid soap), and x2 (of the liquid soap) they will sell per month. According to the model, the amount of units sold depends on the prices p1,p2 (in dollars) of solid and liquid soap through the equations ( see attached for equation) Set up a function to describe how the total profit (revenue - costs) depends on the unit prices p1 and p2.
A cyclist takes 4 hours to travel from Town A to Town B. The cyclist's average speed for the first hour is half the cyclist's average speed for the second hour, and the cyclist's average speed for the first two hours is equal to twice the cyclist's average speed for the last two hours. If the cyclist traveled at an average speed of 9 miles per hour for the 4-hour trip, what was the cyclist's average speed, in miles per hour, during the first hour of the trip? 6. O 8 O 16 00 0 0
The Hydro water department has a monthly service charge of $15 10 and a volume charge of $2 25 for every 100 cubic foet of water. The total monthly cost is equal to the service charge plus the charge for the volume used duning the month. If we let x represent the number of cubic feet of water (in hundreds) and y represent the total monthly cost, then we have total monthly cost volume charge service charge y-2.25x+ 16.1o If the Johnson family used 200 ess water this month than last month, then they can expect OA an increase in their water bil of $30.20 OB. a decrease in their water bil of S4.50 C. a decrease in their water bll of $30.20 OD an increase in their water bil of $4.50
