Answer:
The domain is the interval [5,∞)
Step-by-step explanation:
we have
we know that
The radicand (number under a radical) must be greater than or equal to zero
so
solve for x
Adds 5 both sides
therefore
The domain is the interval [5,∞)
All real numbers greater than or equal to 5
0, 1, 2, and 3 are greater than -1 and less than 4
I believe it is a 62.5 percent chance.
Hi. Unfortunately there is no statement to determine if it's true or not. However, I would just give the correct statement.
Secant function is the inverse of cosine. In trigonometry, a right triangle has one 90 degrees angle. It consists of the hypotenuse(h), the adjacent side (a), and the opposite side(o), with respect to the angle. For cosine, it is adjacent over hypotenuse. Since secant is the inverse, it would be hypotenuse/adjacent. Hypotenuse is the longest side.
Hence, sec theta = 15/9
I hope this helps :)
