The City Council proposed to utilize a government-owned land with an area of 9,600 square meters. One-third of it will be used for a picnic area while the rest of the land will be planted by mango trees. As the city engineer, you were tasked to determine the following: the dimensions of the picnic area 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 number of mango trees that leads to a maximum yield given that if 70 trees are planted, the average yield per tree will be 300 kilos while the average yield will decrease by 3 kilos per tree for each additional tree on the same area due to overcrowding. As an Engineer, cite other instances aside from the situations given above where optimization (one minimization) can be applied.
The life expectancy for females born during 1980-1985 was approximately 80.6 years. This grew to 81 years between 1985-1990 and to 81.6 years between 1990-1995. I have to find a model for this data by finding a quadratic equation whose graph passes through the points (0,80.6) (5,81) and (10,81.6). Based on that, estimate the life expectancy for females born between 1995 and 2000 and those born between 2000 and 2005.
