Given that,
The camera sights the stadium at a 7 degree angle of depression. 
The altitude of the blimp i slide 300 m.
To find,
The line of sight distance from the camera to the stadium.
Solution,
If we consider a right angled triangle. Let x is its hypotenuse i.e. the line of sight distance from the camera to the stadium. Using trigonometry :

So, the line of sight is at a distance of 2461.65 m from the camera to the stadium.
 
        
             
        
        
        
Answer:
The value of f(-3) = -3
Step-by-step explanation:
It is given that f(x) = 3(x+2), in order to find f(-3), we have to substitute x = -3 into the function, f(x) :
f(x) = 3(x+2)
f(-3) = 3(-3+2)
 = 3(-1)
 = -3
 
        
             
        
        
        
Answer:
Step-by-step explanation:
For the disease having force of mortality  µ.
we apply exponential distribution law
probability of dying within 20 years 
p( x <20) =  = .1
 = .1
 = .9
 = .9
For the disease having force of mortality  2µ.
we apply exponential distribution law
probability of dying within 20 years 
p( x <20) = 1 -  
 
= 1 - ( .9)²
= 1 - .81
= .19 
or 19% 
 
        
             
        
        
        
The equation that models the difference in the projected enrollments for
public schools and private schools as a function of the number of years
since 1985 is B - R = (-18.53t^2 + 975.8t + 48140) - (80.8t + 8049) = -18.53t^2 + 975.8t + 48140 - 80.8t - 8049 = -18.53t^2 + 895t + 40091
