The value of x is 1.66
Step-by-step explanation:
Let use revise the rules of exponential and logarithmic equations
1. If y =
, then 
2. 
Use the rules above to solve the problem
∵ 
- Subtract 2 from both sides
∴ 
change the exponential equation to logarithmic equation
∴ 
∵ 
∴ x = 
∴ x = 1.66
The value of x is 1.66

Answer:
Step-by-step explanation:
a) D/280 = tan(90 - 6)
D = 280tan84 = 2,664 ft
b) D/280 = tan(90 - 16)
D = 280tan74 = 976 ft
ship speed = (2664 - 976) / 43 = 39.2 ft/s

<u>Step-by-step explanation:</u>
The vertex form of an absolute value equation is:
where
(h, k) is the vertex. In the given equation,
, the h-value is 1/2 and the k-value is -2.
So, the vertex (h, k) = (1/2, -2)
