Find the dimensions of a rectangular corral split into 2 pens of the same size producing the greatest possible enclosed area given 100 feet of fencing. Width = help (numbers) Length = help (numbers) cd deelean.com JMaximum areadimum Value of a Quadratic Function A backyard farmer wants to enclose a rectangular space for a new garden within her fenced bdckyard. She has purchased 80 feet of wire fencing to enclose three sides, and she will use a section of the backyard fence as the fourth side. a. Find a formula for the area enclosed by the fence if the sides of fencing perpendicular to the existing fence have length L. b. What dimensions should she make her garden to maximize the enclosed area? Solution Let's use a diagram such as Figure 10 to record the given information. It is also helpful to introduce a temporary variable, W, to represent the width of the garden and the length of the fence section parallel to the backyard fence. Garden 224W=80 w> 80-2L Figure 10 A=-22+ A= L.W…

Find a polynomial that fits the points (−2, 3), (−1, 5), (0, 1), (1, 4), and (2, 10).

The population of a certain country was approximately 50 million in 1900, 225 million in 1950, and 350 million in 2000. Construct a model for this data by finding a quadratic equation whose graph passes through the points (0,50), (50,225), and (100,350). Use this model to estimate the population in 2050. Let x be the number of years since 1900 and y be the population in millions. y = (Use integers or decimals for any numbers in the expression.) According to the model, what will the population be in the year 2050? million y = -C
