Answer:
The answer to your question is Yes.
Step-by-step explanation:
The math in this problem is that we need to use the Pythagorean theorem to solve it. Pythagorean theorem is part of trigonometry a branch of Maths.
Data
base = 9 ft                      
length = 37 ft
height = ?
Pythagorean theorem
                                      c² = a² + b²
length = c
base = a
height = b
                                    37² = 9² + b²
-Solve for b
                                     b² = 37² - 9²
-Simplify
                                     b² = 1369 - 81
                                     b² = 1288
-Result 
                                    b = 35.88
-Conclusion
The ladder will reach a height higher than 35 ft.  
 
        
             
        
        
        
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that 
Probability that they were left handed P(L)= 40%
Probability that they were Democrats P(D)= 47%
So, P(L∩D) = 135 = 0.13
Now, to check whether they are independent or not. 
We will find P(L) × P(D) is given by

Since P(L) . P(D) ≠ P(L∩D)
So, they are not independent.
Hence, Option 'c' is correct.
 
        
             
        
        
        
Answer:
The principal square root of -4 is 2i.
Step-by-step explanation:
 = 2i
 = 2i
We have the following steps to get the answer:
Applying radical rule 
We get 
As per imaginary rule we know that 
= 
Now 
Hence, the answer is 2i.
