Answer:
x ≈ 11.5° or 168.5°
Step-by-step explanation:
csc² x − 5 csc x = 0
Factor:
csc x (csc x − 5) = 0
Set each factor to 0 and solve:
csc x = 0
sin x = undefined
no solution
csc x − 5 = 0
csc x = 5
sin x = 1/5
x = arcsin(1/5)
x ≈ 11.5° or 168.5°
This looks like an ellipse.
Complete the square for y: 9(y²-6y-7)=9(y²-6y+9-9-7)=9((y-3)²-16).
Rewrite the equation:
4x²+9(y-3)²-144=0; 4x²/144+9(y-3)²/144=1; x²/36+(y-3)²/16=1.
Standard equation of an ellipse is (x-h)²/a²+(y-k)²/b²=1, where (h,k) is the origin or centre.
This is the equation of an ellipse with centre (0,3), a=6 and b=4 (semimajor and semiminor axes).

Answer:
The corresponding point is <em>(-8, -6).</em>
Step-by-step explanation:
Given that
(-6,-6) lies on the graph of 
A function is represented in the form:
i.e. (-6,-6) means value of x = -6 is put and value y came out as -6.
Now, we have to find the corresponding point on 
.
We know the value of 
Let us find the value of x where 
becomes equal to -6
So, let us put value of 
in :
(as per given statement)
So, the corresponding point is <em>(-8, -6).</em>
