Answer:

4,022.5 m

Step-by-step explanation:

When an observer watches an object lying on the ground from an elevated point on the ground then the angle formed between horizontal line and the line of vision is known as ANGLE OF DEPRESSION.

When an observer watches an object from a point on the ground situated at some height from the ground from the ground then the angle formed between horizontal line and the line of vision is known as ANGLE OF ELEVATION .

Let the distance of the rock from the airplane be x meters.

\sin \: 25 \degree =  \frac{1700}{x}  \\  \\  0.4226182617 =  \frac{1700}{x}   \\  \\ x =  \frac{1700}{0.4226182617}  \\  \\ x = 4,022.54269 \\  \\ x = 4022.5 \: m

Which of the following describes the polynomial function ??? HELP
JulsSmile [24]

Answer:

B. The function has an even degree.

Step-by-step explanation:

We have been given an image of a polynomial function. We are asked to choose the correct options about our given polynomial.

A. The function has a negative leading coefficient.

Upon looking at our given graph, we can see that it is an upward opening parabola, so leading coefficient can't be negative, therefore, option A is not true.

B. The function has an even degree.

Upon at our given graph, we can see that it is symmetric to y-axis, therefore it has an even degree polynomial and option B is the correct choice..

C. The function has zero turning points.

Upon looking at our given graph, we can see that as function approaches towards 0 from negative infinity it is decreasing. As function increases positive infinity from 0, it is increasing, therefore, our function has a turning point at x=0, therefore, option C is incorrect.

D. The function has one x-intercept.

Since our function never intersects x-axis, therefore, function has no x-intercept and option D is incorrect as well.
