Answer:
The answer to your question is a = 1.1; b = 24
Step-by-step explanation:
Data
Earth's mass = 5.97 x 10²⁴ kg
Venus' mass = 4.87 x 10²⁴ kg
Process
1.- Subtract the Venus' mass to the earth's mass.
5.97
<u> - 4.87</u>
1.1
2.- Write the result in scientific notation
1.1 x 10²⁴ kg
3.- Result
a = 1.1
b = 24

Answer:
Part 1) Australia 
Part 2) China 
Part 3) Mexico 
Part 4) Zaire 
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by

where
P(t) is the population
t is the number of years since year 2000
a is he initial value
r is the rate of change
Part 1) Australia
we have

substitute


Find the expected population in 2025,
Find the value of t
t=2005-2000=5 years
substitute the value of t in the equation

Part 2) China
we have

substitute


Find the expected population in 2025,
Find the value of t
t=2005-2000=5 years
substitute the value of t in the equation

Part 3) Mexico
we have

substitute


Find the expected population in 2025,
Find the value of t
t=2005-2000=5 years
substitute the value of t in the equation

Part 4) Zaire
we have

substitute


Find the expected population in 2025,
Find the value of t
t=2005-2000=5 years
substitute the value of t in the equation
