Answer:
125
Step-by-step explanation:
To find the common ratio, take the second term and divide by the first term
1000/2000 = 1/2
We multiply each term by 1/2
2000, 1000, 500
To find the next term 500*1/2 = 500/2 = 250
To find the 5th term
250*1/2 = 125
3.25 repeating as a fraction is 1.25 plus 1.25 plus 1.25 that will equal 3.25.
A square root of any number greater than 0 always has two answers, one positive and one negative.
Squareroot (36) = 6 or -6.
Since 6×6=36 and -6×-6=36.
Squareroot (0)= just 0 because there is no negative 0 (:
Answer:469 million
Step-by-step explanation:
Given
The population of a country at t=1900 is 420 million
and P'(t) is a constant therefore P(t) is a linear function of time
assuming P(t)=7t +c
at t=0 i.e. 1900 at starting Point P(t)=420 million
i.e.


Thus 

Thus at 1907 Population is 469 million
P'(t)=7 indicates that growth rate of Population is constant equals to 7 billion
|-13| = 13
Whenever || is used, the outcome of the number inside the bracket will always be positive
