Answer:
The 1st graph
Step-by-step explanation:
When you graph the equation in a graphing calc, you should be able to see that the graph most similar would be the 1st one.
Answer:
hundred thousands
Step-by-step explanation:
The area of the circular sector is

From that, the equation for the central angle is

The perimeter of the circular sector is the sum of the arc length and twice the radius.

From that, the equation for the central angle is

The value of r can be found by equating these two expressions for θ.

By any of several means, you can find that r=0.2 or 1.25. The latter value corresponds to the requirement that the central angle be less than 90°. The radius is ...
1.25 miles.
X would equal 1/2 the measure of the intercepted arc, or 45/2
Y = 1/2 the difference of the intercepted arcs, so (105-45)/2
