Answer:

There are infinite solutions.

Think about it. The equation says essentially:

12 + any number = 12 + any number.

y + 12 = y + 10 + 2

y + 12 = y + 12

y - y = 12 - 12

0 = 12 - 12

0 = 0

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 $N(0) = 37.1$

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

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:

$N(t) = 37.1(1.38)^t$
