Answer: What is the answer you need?
Step-by-step explanation:
The inverse functions of sine, cos and tan functions are csc, sec and cot respectively.
<u>Step-by-step explanation:</u>
The reciprocals of sine, cos and tan functions are csc, sec and cot functions. The reciprocal of cosine function is secant, (sec) sec θ = 
The inverse or reciprocal function is cosecant (csc), 
The inverse tangent function is cotangent (cot) , expressed in two ways: 
or 
So 
then its reciprocal or inverse is termed as cot θ.

Answer:</h2>
<u>The mean altitude will be</u><u> -54 per minute</u>
<h2>
Step-by-step explanation:</h2>
We are given with altitude change as -378 feet over 7 minutes
Now
We need feet per minute
So -378 / 7 will give us the altitude change per minute
-378 / 7 = -54
Therefore the mean change of altitude in feet per minute is -54 per minute
<span>Subtracting −b+3 from −11b−4, would mean:
-11b - 4 Minus (-b + 3)
</span>
<span>-11b - 4 - (-b + 3)
</span>
<span>-11b - 4 + b - 3
-11b + b - 4 - 3
-10b - 7
I hope this helped.

Answer:
The given relation is not a function
Step-by-step explanation:
- The relation becomes a function if every x-value has only one y-value
- A function is a relation in which each input (x) has only one output (y)
<em>To test the graph is a function or not, draw a vertical line intersects the graph in different positions, if the line cuts the graph in just one point in all positions, then the graph represents a function.</em>
<em />
From the given figure
∵ The endpoint of the diameter of the semi-circle are (0, -2), (0, 2)
→ The x-coordinate = 0 has two values of y = -2, 2
∴ At x = 0, y = -2 and 2
∴ Not every x has only one y
∴ The given relation is not a function
<em>If you draw a vertical line intersects the semi-circle in different positions, it will intersect the semi-circle in 2 points, So the graph does not represent a function </em>
