The table below gives the population of a country at 10-year intervals for the years 1950-2000. Population (in millions) Year 1950 150 1960 170 1970 198 1980 223 1990 252 2000 289 (a) Assuming an exponential growth model of the form p(t) = cekt, where p(t) is the population (in millions) at time t, use least squares to find the equation for the growth rate of the population. (Hint: Let t = 0 be 1950, t = 1 be 1960, etc. Round k to three decimal places.) p(t) = (b) Use the equation to estimate the population of the country in 2010. (Round your answer to two decimal places.) million
Minimization
In mathematics, traditional optimization problems are typically expressed in terms of minimization. When we talk about minimizing or maximizing a function, we refer to the maximum and minimum possible values of that function. This can be expressed in terms of global or local range. The definition of minimization in the thesaurus is the process of reducing something to a small amount, value, or position. Minimization (noun) is an instance of belittling or disparagement.
Maxima and Minima
The extreme points of a function are the maximum and the minimum points of the function. A maximum is attained when the function takes the maximum value and a minimum is attained when the function takes the minimum value.
Derivatives
A derivative means a change. Geometrically it can be represented as a line with some steepness. Imagine climbing a mountain which is very steep and 500 meters high. Is it easier to climb? Definitely not! Suppose walking on the road for 500 meters. Which one would be easier? Walking on the road would be much easier than climbing a mountain.
Concavity
In calculus, concavity is a descriptor of mathematics that tells about the shape of the graph. It is the parameter that helps to estimate the maximum and minimum value of any of the functions and the concave nature using the graphical method. We use the first derivative test and second derivative test to understand the concave behavior of the function.
