The number of permutations of the 4 different letters, taken two at a time, is given by:
Answer: 2,215,000
Step-by-step explanation:
Given: The quadratic function models the population of a city where x represents the number of years since 2005.
To Find: population of the city in 2010
We need to put x= 2010-2005 = 5
Hence, the estimated population of the city in 201 = 2215 thousands or 2,215,000 .
$478 by using the provided formula ...
Explanation : income = $523 , expense = $ 45 , profit =523-45= 478
D
You figure out the absolute value by determining how far the number is from the point 0 on a number line.
The general formula for a equation of the form:
is:
In this case we notice that a=1, b=-4 and c=3. Plugging this values in the general formula we get:
then:
and
Therefore, x=3 or x=1.
