Are you sure you wrote all the correct numbers because it does not work
3n<50
n<50/3
The variable N represents a whole number.
For what values of n will the sum of n+3 be less than 50?
Hey! You just have to square root the 2 and 5 then multiply by 11 so the answer I came up with is 34.78505426185218
I hope I helped!
Answer:
a) tan = 15/8
b) csc = 17/15
d) sec = 17/8

Let me know if this is right Please :(

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)
