the annual rate of inflation is given by the formula I = (p2/p1)^1/n - 1, where p1 is the initial price of an item and p2 is the

final price of an item over a period of n years. In 1980, the average price of an ounce of gold was $850. By 2011, the average price was $1,800. In this situation, what is n?

Answer:

<h2>The value of n is 31 years.</h2>

Step-by-step explanation:

The given equation is formed by different variables, where n indicates the period of time in years where the rate of inflation is calculated.

In this case, we have a period from 1980 to 2011. The difference between these years would be the period of time used to find the inflation rate.

2011-1980=31

Therefore, the value of n is 31 years.

Usimov [2.4K]

The growth of the plant last year was 25 inches if the normal growth was ten inches more than twice the amount of last year.

<h3>What is linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The normal yearly growth of a plant is 60 inches.

Let's suppose the growth of the plant last year was x

The normal growth was ten inches more than twice the amount of last year.

From the above statement:

10 + 2x = 60

2x = 50

x = 25 inches

Thus, the growth of the plant last year was 25 inches if the normal growth was ten inches more than twice the amount of last year.
