q4 Suppose milk is produced in a certain area. Some people might argue that because of transportation costs, the cost of milkincreases with the distance of markets from that area. Suppose the milk prices in eight cities are as follows.Cost of MilkDistance from(per 2 L)Milk-Producing Area (km)$2.661,2452.314252.451,3462.529732.192552.528652.401,0802.37296а.Use the prices along with the distance of each city from the milk-producing area to develop a regression line to predict theprice of 2 L of milk by the number of kilometres the city is from the milk-producing area.(Do not round the intermediate values. Round your answers to 5 decimal places, e.g. 1.75895.)ŷ =+

The City Council proposed to utilize government-owned land with an area of 15,000 square meters. One-third of the area will be used to plant mango trees while the rest of the land is where an emergency field hospital shall be built. As the city engineer, you were tasked to determine the following: 1. the dimensions of the land planted with mango trees with minimum cost of fencing given that area is to be rectangular and to be fenced off on three sides not adjacent to the highway. 2. the rate at which the total average number of COVID cases is increasing at x=10 tents and dx/dt=1 tent per day, given that if 25 tents are built, the average number of COVID cases per tent will be 6 cases while the average number of cases will increase by 2 per tent for each additional tent in the same area due to overcrowding.

An oil refinery is located on the north bank of a straight river that is 1 km wide. A pipeline is to be constructed from the refinery to storage tanks located on the south bank of the river 4 km east of the refinery. The cost of laying pipe is $300,000/km over land to a point P on the north bank and $600,000/km under the river to the tanks. To minimize the cost of the pipeline, how far (in km) from the refinery should P be located?
An oil refinery is located on the north bank of a straight river that is 1 km wide . A pipeline is to be constructed from the refinery to storage tanks located on the south of the river 6 km east of the refinery . The cost of laying pipe is 500, 000 per km over the land to point P on the north bank and 1,000,000 per km under the river to the tanks . To minimize the cost of the pipeline , how far from the refinery should P be located ?
