Answer:
The length of the rope between the boat and the dock is of 30 feet.
Step-by-step explanation:
Given:
tan(40) ≈ 0.839
Angle of depression = 40 (deg)
Distance between boat and the floor of the ocean = 25.17 feet
If we look into the diagram we can see that,they form 2 right angled triangle.
Where we can say that :
Distance between boat and dock = Rope's distance = Base of the triangle.
Let the length of the rope be 'x' feet.
Considering the dotted triangle:

Length of the rope between the boat and the dock is 'x' = 30 feet.

Answer:
C
Step-by-step explanation:
-2x^2 + 2x -3
-2(5)^2=
-50
2(5)
= 10
-50+10-3
is -43 so C
Answer:
Odd function
Step-by-step explanation:
The given function is
We know that:
- The function is even if f(-x) = f(x)
- The function is odd if f(-x)=-f(x)
- If the function doesn't satisfy these two properties then it is neither odd nor even.
Hence, we substitute x = -x to find f(-x)
Since, f(-x)=-f(x). Hence, the function is odd.
^^^^^ they are correct !!!!!
