Answer:
Height of plane = 25971.7 meters
Step-by-step explanation:
let H =height of plane
Let x = distance ray to the point under the plane
800 foot = 245meters
1 mile = 1609meters.
Tan 81 =  -----------------------(1)
    -----------------------(1)
Tan 67 =  -----------------------(2)
    -----------------------(2)
6.3134  =  ------------------------(3)
   ------------------------(3)
2.3556 =   -----------------------(4)
    -----------------------(4)
from (3) and (4)
H = 10158.26 + 6.3134x  ---------------(a)
H = 245 + 2.2336x ---------------(b)
equating both (a) and (b) we have:
9913.26 = 3.9576x
x = 2504.74
Subst. x = 2504.74 into (a)
H = 25971.7meters
 
        
             
        
        
        
Answer:
-77
Step-by-step explanation:
Simply plug in: 
Because the "-" sign is outside the parentheses, you would distribute.
It would then be: -3-4. *positive and negative=negative, negative and negative=positive. -3-4=-7. It would then be: (-7) · ((3-(-4)(2))
(-4)(2)=-8. →(3-(-8))=(3+8)=11. The equation would then be: (-7) · (11)= -77
 
        
                    
             
        
        
        
Answer:
   12.3 months
Step-by-step explanation:
You want the number of months (m) such that ...
    1 - 17% = (1 -1.5%)^m
Taking logarithms:
   log(0.83) = m·log(0.985)
   m = log(0.83)/log(0.985) ≈ 12.3 . . . . months
 
        
             
        
        
        
Answer:
 a horizontal translation by 3 units left
Step-by-step explanation:
f(x)= |x|
we are given with absolute function f(x)
g(x)  = |x+3|
To get g(x) from f(x) , 3 is added with x
If any number is added with x  then the graph of the function move to the left
Here 3 is added with x, so the graph of f(x) moves 3 units left to get g(x)
So there will be a horizontal translation by 3 units
