State whether the function (x) = 150 (1.09)x is growing or decaying and find the rate.

1 answer:

6 0

It is growing at a rate of 9%.

The exponential equation is in the form

f(x) = a*(1+r)ˣ, where a is the initial value, r is the growth rate written as a decimal number, and x is the number of time periods. 1.09 is in the place of 1+r; this means r = 0.09 or 9%. Since we have a number greater than 1, it is increasing.

The histogram shows the number of miles driven by a sample of automobiles in New York City. What is the maximum possible number

hjlf

Answer:

The maximum possible number of miles traveled by an automobile included in the histogram is 40,000 miles.

Step-by-step explanation:

A histogram is a bar graph reprinting the frequency of various categories.

In a histogram the y-axis represents the frequency and the x-axis represents the categories.

Consider the histogram provided for the number of miles driven by a sample of automobiles in New York City.

The y-axis represents the frequency and the x-axis represents the number of miles driven.

The category 10,000 miles has the highest frequency at 30.

And the maximum possible number of miles traveled by an automobile is 40,000 miles.
