Answer:
$890.4
Step-by-step explanation:
840 + .06(840)
840 + 50.4
890.4
 
        
                    
             
        
        
        
It will help you.
And the answer is -99 feet below the surface.
-86+(-13)
= -99
        
                    
             
        
        
        
No more means less or equal.So, correct answer is <span>A. x ≤ 8 .</span>
        
             
        
        
        
That would be 0.2
Hope this helps. :)
        
             
        
        
        
Answer:
a. 360.323 m
b. 
Step-by-step explanation:
Distance covered from A to B = speed x time
                                                  = 110 x 2.8
                                                  = 308 m
Distance covered from B to C = speed x time
                                                   = 110 x 1.7
                                                   = 187 m
The sum of angles at B =  +
 + 
                                        = 
a. The distance of the plane from it starting point to C can be determined by applying the cosine rule. 
 =
 =  +
 +  - 2ac Cos B
 - 2ac Cos B
Sot hat;
 =
 =  +
 +  - 2(187 x 308) Cos
 - 2(187 x 308) Cos 
But, Cos  = 0
 = 0
So that,
 =
 =  +
 + 
   = 34969 + 94864
   = 129833
b = 
   = 360.323
The distance from A to C is 360.323 m.
b. Applying the sine rule;
 =
 =  
 
 =
 =  
 
 =
 =  
 
Sin A = 
          = 0.5190
⇒ A =  0.5190
 0.5190
        = 
The bearing of the plane from its original location =  +
 + 
                                                      =
