Answer:
It had flown 2620 ft along the diagonal.
Step-by-step explanation:
When the plane is taking off it forms we can form a triangle with it's height, horizontal distance and diagonal distance, which can be seen in the attached drawing. We can use the sine relation on the right triangle to determine "x", as shown below:
sin(11°) = 500/x
x*sin(11) = 500
x = 500/[sin(11)] = 2620 ft
It had flown 2620 ft along the diagonal.

Answer:
B
Step-by-step explanation
5:1 means for every 1 table their is 5 chairs.
And for every 5 chairs there is 1 table.
On the added picture you can see that graphs of functions

and

have two points of intersection. The x-coordinates of these points are the solutions of the equation

.
Hence, the approximate solutions are x=-1.9 and x=1.6.
