zmey [24]

Answer:

(a) 6.2843 billion

(b) 6.8716 billion

Step-by-step explanation:

Since there is a constant growth rate of 1.5% per year, and the population in 2002 was 6.1 billion people. The general equation for the total world population, in billions, after 2002 is:

P(t) = 6.1*(1+0.015)^t

With t being the time, in years, after 2002.

a) What was the population in 2004?

t=2004-2002=2\\P(2) = 6.1*(1.015)^2\\P(2) = 6.2843 \ billion

b) What was the population in 2010?

t=2010-2002=8\\P(8) = 6.1*(1.015)^8\\P(8) = 6.8716 \ billion

Subtract. ​ 7/8-(-3/8) ​ Enter your answer in the box as a fraction in simplest form?
Effectus [21]
Simple....

so you have: \frac{7}{8}-(- \frac{3}{8}  )

There's the law where if the number outside your parentheses is negative along with the number in the parentheses; it converts into positive...

-->>x-(-x)
--->>x+(+x)

This being said.....

\frac{7}{8} - (-\frac{3}{8} )

-->> \frac{7}{8} +(+ \frac{3}{8} )

-->>>\frac{10}{8}

But remember, you want to simplify it....

\frac{10}{8} = \frac{5}{4} (Decimal form..1.25)

Thus, your answer.
