That's a right triangle with hypotenuse 3000 and the height y is the side opposite the elevation angle of 15 degrees.

y = 3000 \sin 15^\circ


We can actually compute \sin 15^\circ exactly but I won't bother.

y \approx 776 \textrm{ feet}

Need answer ASAP! I only have two questions left!!!
Westkost [7]

Answer: B) Adjacent interior angle

As the name implies, the angle is inside the triangle and it is adjacent (ie next to) the exterior angle. Contrast this with a remote interior angle, which is also inside the triangle, but it is not adjacent to the exterior angle in question. Alternate interior angles won't apply here because we don't have a set of parallel lines with a transversal cut.

Use the drawing tools to graph the distinct real zeros of the polynomial function p(x) = x3 - 2x2 - 4x2 + 8x.
vodomira [7]

Answer:

Step-by-step explanation:

My drawing tool is Desmos. It can be used at no cost.

the graph will not work unless you combine -2x^ and -4x^2 to give - 6x^2.

If you try and graph it as given, you get a straight line going for quadrant 4 to quadrant 2.

But you will note that when you make the addition of the 2 middle terms, it gives you the graph that I have enclosed, which is the one you should expect. I'm wondering why you get a straight line when you try and graph what you were given.
