the population will reach 8 billion by 2012 ,as calculated by properties of logarithm.
<h3>What is Logarithm?</h3>
- The opposite of exponentiation is the logarithm.
- This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.
- A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.
Given:
- y = 6.72 (
), where
- y = population in billions
- x = time in years
To find: Year when population is 8 billion, i.e., y = 8.
Finding:
8 = 6.72 (
)
=> 
Taking log on both sides
=> 
=> log(1.19) = x (log 1.014) (as
)
=>
= x
=> x = 
=> x = 12.58
Hence, the population will reach 8 billion by 2012 ,as calculated by properties of logarithm.

The correct answer is B. Hope this helps!
4|-7-2| = 4|-9| = 4x9 = 36
Answer:
10
Step-by-step explanation:
AB + BC = AC and AC = 14
x + 15 + 2x + 32 = 14 add like terms
3x + 47 = 14 subtract 47 from both sides
3x = -33 divide both sides by 3
x = -11 now the length of BC
2x + 32 replace x with -11
2*(-11) + 32 = 10
