If x and y are both negative when is x-y positive
jarptica [38.1K]
Hmm

let's try some numbers

we have 3 scenarios
x>y
x=y
x<y

x>y
x=-1 and y=-2
x-y=-1-(-2)=-1+2=1
it's positive when x>y

x=y
x=-1, y=-1
-1-(-1)=-1+1=0
nope

x<y
x=-2 and y=-1
-2-(-1)=-2+1=-1
nope


x-y is positive when 0>x>y

The equation y=6.72(1.014) x models the world population y , in billions of people, x years after the year 2000 . Find the year
Marizza181 [45]

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 ( 1.014^x), where
  1. y = population in billions
  2. x = time in years

To find: Year when population is 8 billion, i.e., y = 8.

Finding:

8 = 6.72  ( 1.014^x)

=> \frac{8}{6.72}= ( 1.014^x)

Taking log on both sides

=> log(\frac{8}{6.72})= log( 1.014^x)

=> log(1.19) = x (log 1.014) (as log_b(a)^m = m (log_b(a)) )

=> \frac{log(1.19)}{log (1.014)} = x

=> x = \frac{0.0755}{0.006}

=> x = 12.58

Hence, the population will reach 8 billion by 2012 ,as calculated by properties of logarithm.
