What is the decay factor of the exponential function
represented by the table?

Given:

The table of values of an exponential function.

To find:

The decay factor of the exponential function.

Solution:

The general form of an exponential function is:

             ...(i)

Where, a is the initial value and is the decay factor and is the growth factor.

The exponential function passes through the point (0,6). Substituting in (i), we get

The exponential function passes through the point (1,2). Substituting in (i), we get

Here, lies between 0 and 1. Therefore, the decay factor of the given exponential function is .

Hence, the correct option is A.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

the answer is 5/14.

hope this .
