Explanation Given: In 1980 , the median age of the population of the U.S. was 30.0 years. This means that approximately half the population of the country was under 30.0 years old and approximately half the population of the country was over 30.0 years old. By 2035 , the median age is expected to peak at 39.1 years. An equation that can be used to predict the median age N (in years) of the population of the United States is N = 32.53 + 1.55 l n x . Here, x is the number of years since 1990 and x ≥ 1 . Formula used: N = 32.53 + 1.55 l n x . Calculation: Consider the provided expression: N = 32.53 + 1.55 l n x . The value of x corresponding to year 2000 is 10 . Substitute 10 for x . N = 32.53 + 1.55 l n 10 . Further solve, N = 32.53 + 1.55 ( 2.302 ) N = 32

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
