Answer:
Its a right angle triangle so trigonometry is used.
a is the hypotenuse, b is the adjacent.
Use sin to find a. Use tan to find b.

For a better understanding of the solution provided here please go through the diagram in the file attached.
As can be seen from the diagram, we need to find the initial horizontal component of the vector that represents the velocity of the ball. Let us represent that initial horizontal component by, .
Now, since basketball player shoots the ball with an initial velocity, , of 14.4 ft./sec at an angle of 41.9 degrees with the horizontal, we can find the initial horizontal component by, using the following formula:
ft./sec
Answer : option D
we need to find out the graph shows a mixed-degree system with exactly one solution
The solution of two graphs will be the intersection of two graphs
In the first graph,
There is no intersection of both circles, So no solution
second graph,
The circle intersects the parabola at two point, so two solution for this graph
Third graph,
The circle and line does not intersects, so no solution
Fourth graph,
Both parabola intersects at one point, so one solution for this graph
So option D has exactly one solution
