aalyn [17]

Answer:

N(t) = 37.1(1.38)^t

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

N(t) = N(0)(1+r)^t

In which N(0) is the initial value and r is the rate of change, as a decimal.

37.1 million in July 1998

This means that N(0) = 37.1

So

N(t) = 37.1(1+r)^t

In July 2005, the internet was linked by a global network of about 353 million host computers.

This is 2005 - 1998 = 7 years, so N(7) = 353. We use this to find r.

N(t) = 37.1(1+r)^t

353 = 37.1(1+r)^7

(1+r)^7 = \frac{353}{37.1}

\sqrt[7]{(1+r)^7} = \sqrt[7]{\frac{353}{37.1}}

1 + r = (\frac{353}{37.1})^{\frac{1}{7}}

1 + r = 1.38

The formula is:

N(t) = 37.1(1.38)^t
