A higher positive slope means a steeper upward tilt to the curve, which you can see at higher output levels. A negative slope that is larger in absolute value (that is, more negative) means a steeper downward tilt to the line.
Answer:
3695.5 m
1530.73 m
Step-by-step explanation:
Given in the question,
The distance probe travels at an angle of depression 67.4 from the ship to the ocean surface = 4000m
We will use trigonometry identities
<h3>sinФ = opposite / hypotenuse</h3><h3>cosФ = adjacent/ hypotenuse</h3>
1)
distance of probe from top of sea to surface = x
cos(90 - 67.5) = x / 4000
x = 3695.5 m
2)
horizontal distance from ship to probe = y
sin(90-67.5) = y / 4000
y = 1530.73 m

Step-by-step explanation:
Given:
The different relations in the options.
To find:
The relation which represents a function.
Solution:
A relation is called a function if there exist a unique output (y-value) for each input (x-value).
In option A, there exist two outputs y=7 and y=1 for a single input x=-1. So, this is not a function.
In option B, there exist two outputs y=-5 and y=2 for a single input x=-1. So, this is not a function.
In option C, there exist two outputs y=2 and y=4 for a single input x=3. So, this is not a function.
In option D, there exist only one value of y for each x. So, this is a function.
Therefore, the correct option is D.
