The number of cell phone accounts in a certain country has increased exponentially for the last decade. The number of cell phone accounts (in millions) in this country can be approximated by the following function. Estimate the number of cell phone accounts in 2003.
f(x)= 114.8e.125x (0
What was the approximate number of cell phone accounts in 2003?

See Below

Step-by-step explanation:

The equation estimating the number of cellphones in the country is:

Where x = 0 corresponds to year 2000

thus,

x = 1 is year 2001

x = 2 is year 2002

x = 3 is year 2003

and so on...

We want approx. number of cellphones in the country in 2003. This corresponds to x = 3. So substituting in the equation we get:

So, approximately there were 167.03 million cellphones in the country in 2003

a² + b²= c²

24² + 7² = c²

c= 25

i think it would be 42cm
