It is 6 units because you find the absolute value of the two different coordinates, in this case it is 4 and -2. Since they belong in different quadrants (one x or y value is positive and the other is negative) you add them. If they are both in the same quadrant, you subtract them. 
        
             
        
        
        
Answer:
The population reaches 7 million people in the year 2032.
Step-by-step explanation:
We have that

Using this model, find the year when the population reaches 7 million people.
This is x years after 2000, in which x is found when f(x) = 7. So




We have to following logarithm rule

So we apply log to both sides of the equality




2000 + 32.66 = 2032
The population reaches 7 million people in the year 2032.
 
        
             
        
        
        
Answer: x=17
Step-by-step explanation:
(5 + x)/(16 + x) = 2/3
Cross multiply to get:  
15+3x = 32 + 2x
 
        
             
        
        
        
Answer:

Answer:
Step-by-step explanation:
From the given data
we observed that the missile testing program 
Y1 and Y2 are variable, they are also independent
We are aware that
 have
 have  distribution with 1 degree of freedom
 distribution with 1 degree of freedom
and  has x^2 with 2 degree of freedom
 has x^2 with 2 degree of freedom

Since we have to find the density formula

We use method of transformation

There inverse function is 
We derivate the fuction above with respect to u

Therefore,
