If 270°<θ<360°, and tan⁡ θ= - 1/2, what is the value of tan⁡(−θ)?
stiv31 [10]

Check the picture below.

let's recall that once we move an angle in the opposite direction of the 0-line or x-axis, we end up with a negative counterpart angle.

since we know that θ is on the IV Quadrant, then its negative counterpart must be across the line, and tangent is negative on the IV Quadrant, and positive on the I Quadrant.

Given h of x equals 2 times the square root x minus 5 end root, which of the following statements describes h(x)?
zaharov [31]

The option that describes h(x) is B. The function h(x) is increasing on the interval (5, ∞).

<h3>What is a function?</h3>

In mathematics, a function simply means a relation between the inputs and the outputs.

In this case, the information given is that h(x) is 2 times the square root x minus 5. The square root of the negative number cannot be taken, therefore, the domain of the function is restricted.

Since the domain is restricted, the function is increasing. Therefore, the function h(x) is increasing on the interval (5, ∞).
