The statement of Gabriella, “The graph will not have an inverse function.” is incorrect. Option B is correct.
Let us understand about the given graph:
The given graph is a graph of a cube root function.
So, the statement of Noelle, “The graph represents the function ." is correct.
So, option A is not correct.
The inverse of a cube root function is a cubic function.
So, the statement of Gabriella, “The graph will not have an inverse function.” is incorrect.
So, option B is correct.
The domain and range of the cube root function are all real numbers.
So, the statement of Julian, “The domain and range of the function is all real numbers.” is correct.
So, option C is not correct.
From the graph, we can see f(-1) = -1.
So, the statement of Yemen, “The value of f(-1) = -1.” is correct.
So, option D is not correct.
Thus, the statement of Gabriella, “The graph will not have an inverse function.” is incorrect. Option B is correct.

Answer:
The distance between them after 30 minutes is 6.5 km.
Step-by-step explanation:
Speed =
Sarah's speed = 6 km/hr = 1.6667 m/s
Emily's speed = 10 km/hr = 2.7778 m/s
The measure of angle between their bearings =
After 30 minutes (1800 seconds);
distance = speed x time
Sarah would have covered a distance = 1.6667 x 1800
= 3000 m
= 3 km
Emily would have covered a distance = 2.7778 x 1800
= 5000 m
= 5 km
The distance between them, a, can be determined by applying the cosine rule;
=
+
- 2bcCos A
= +
-2(5000 x 3000) Cos 105
= +
-2(5000 x 3000) x (-0.2588)
= 2.5 x + 9 x
+ 7764000
= 41764000
a =
= 6462.5073
a = 6462.5 m
The distance between them after 30 minutes is 6.5 km.
