Answer:
D. (0,5)
Step-by-step explanation:
We are given that,
The function f(x) represents the height of the object 'x' seconds after its launch in the air.
Also, the maximum height of the object is at 2 secs and the object hits the ground at 5 secs.
So, we get the following figure for the situation.
We have that,
<em>Domain of the function is represented by the time after the object is launched i.e. </em><em>the time when the object is in the air</em><em>.</em>
Since, the interval when the object is in the air is (0,5).
Hence, the domain of the given function should be (0,5).

Based on the CPCTC theorem, the complete statement is: RQ ≅ RT.
<h3>What is the CPCTC Theorem?</h3>According to the CPCTC theorem, if two triangles are said to be congruent, then all the corresponding parts of both triangles are congruent.
Given that ΔPQR ≅ ΔSTR, RQ corresponds to RT. Therefore, both sides are congruent to each other.
Thus, the complete statement is: RQ ≅ RT.
