We can form a system of equations:
x*y=90
and
x=2y+3.
Solving gives dimensions of 15 feet by 6 feet.
        
             
        
        
        
Answer:
option D
Step-by-step explanation:
take 39 degree as reference angle
using cos rule
cos 39 = adjacent / hypotenuse
0.77 = x / 7
x = 7*0.77
x = 5.39
x = 5.4
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Let M denote the event that the stock makes money and D denote the event that the stock pays dividends.
It is given that 
Observe that the two events M and D are not independent because if the stock doesn't make money then it will not pay dividends. Therefore the event  (D given M does not occur) is a null event, i.e
 (D given M does not occur) is a null event, i.e
 
 
It is also given that,

Here, we are required to find 

 
        
             
        
        
        
Answer:
A.true
Step-by-step explanation:
The domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.
