Real World Example Functions.

Smart phone sales since 1990

A. Linear

B. Quadratic

C. Exponential

Half life of a pesticide

A. Linear

B. Quadratic

C. Exponential

Smart phone sales since 1990:- linear function

Half life of a pesticide :- exponential function

Step-by-step explanation:

Linear function can be applicable in almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit, therefore smart phone sales since 1990 can be model with linear function

Exponential functions can be applicable in social, scientific, or personal finance situations such as population growth, radioactive decay and half life, therefore half life of pesticide can be model with exponential function.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
