Answer:

The correct answer is B

Step-by-step explanation:

If we plug in x=10 to the equation, we get y=47

Since y is positive, A is not an counterexample

Since y is a function of x, C is not an counterexample

Since the graph of y is a parabola, D is not an counterexample

BC = 6 km

/ ACB = 34°

AC = ?

cos 34° = $\frac{BC}{AC}$

=> 0.829 = $\frac{6}{AC}$

=> AC = $\frac{6}{0.829}$

=> AC = 7.23763570567

=> AC = 7 km

=> AC = 10 km $\:\:\:\:\:\:\:\:$ (nearest tenth)
