Using Pythagoras theorem

<u>Question 1</u>
Now, cosecant = 1/sin
Therefore:

<u>Question 2</u>
Now, secant = 1/cos
Therefore:

1). [(6,1), (6,2), (6,3)] 2). [(0,5), (5,-1), (5,9)] 3). [(1,-6), (3,-5), (1,0)] 4). [(0,8), (1,7), (2,6)]. Which of the followi

Again, look for repeated entries in the domain. If present, the relation cannot be a function. 1 maps 6 to 1, 2, and 3; 2 maps 5 to -1 and 9; 3 maps 1 to -6 and 0; and only 4 has no double mapping. Therefore 4 is a function and the answer.
Number 12 what do you think we do first
Answer:
y= 1/2x-1
Step-by-step explanation:
The equation of a line is y= mx+c
m represents the slope of the line
c represents the y-intercept
So we plug in our information into the equation.
The slope is 1/2 so y= 1/2x + c
The line crosses at (0,-1) which makes -1 the y-intercept as the line crosses at this point on the y-axis.
Therefore, y= 1/2x-1
