Answer:
true?
Step-by-step explanation:
im guessing.
If angle TSV=6x+17 then arc it intercept (SV)would be double it
6x+17=1/2 (15x+13)
12x+34=15x+13
21=3x
x=7
Arc SV=15(7)+13
=118
And angle TSV=6(7)+17
=59
There are 360 degrees in a circle and the measure of the arc would be equal to the central point so the sum of all the arcs equals 360
Arc SV+ arc SUV=360
118+SUV=360
Arc SUV=242

Answers: Choice C and choice D</h3>
y = csc(x) and y = sec(x)
==========================================================
Explanation:
The term "zeroes" in this case is the same as "roots" and "x intercepts". Any root is of the form (k, 0), where k is some real number. A root always occurs when y = 0.
Use GeoGebra, Desmos, or any graphing tool you prefer. If you graphed y = cos(x), you'll see that the curve crosses the x axis infinitely many times. Therefore, it has infinitely many roots. We can cross choice A off the list.
The same applies to...
- y = cot(x)
- y = sin(x)
- y = tan(x)
So we can rule out choices B, E and F.
Only choice C and D have graphs that do not have any x intercepts at all.

If you're curious why csc doesn't have any roots, consider the fact that
csc(x) = 1/sin(x)
and ask yourself "when is that fraction equal to zero?". The answer is "never" because the numerator is always 1, and the denominator cannot be zero. If the denominator were zero, then we'd have a division by zero error. So that's why csc(x) can't ever be zero. The same applies to sec(x) as well.
sec(x) = 1/cos(x)
