Answer:

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.

No the following coordinates do not show a function because of the y-values. In the pairs that you have, (3,5) and (0,5) have the y-values of "5" that are repeating.

Hope this helps. I learned that in math.

A car traveld 32 miles in 4 hours at this rate how many miles will the car travel in 0.5 hours
Mandarinka [93]

Answer:

4 miles

Step-by-step explanation:

In order to find how many miles the car will travel in 0.5 hours, we can set up a proportion.

\frac{32}{4} = \frac{x}{0.5}

We can now cross multiply to find the value of x.

32 \cdot 0.5 = 16\\\\16\div4 = 4

So the car can travel 4 miles in 0.5 hours.

Hope this helped!
