An arc of length 8 in. is intersected by a central angle in a circle with a radius of 3 in. What is the measure of the angle? Ro
2 answers:
Answer: 2.7 radians.
Step-by-step explanation:
The formula we use to find the length of the arc :-
, where
is the measure of the central angle (in radians )and r is the radius .
Given : An arc of length 8 in. is intersected by a central angle in a circle with a radius of 3 in.
i.e. l= 8 in. and r = 3 in.
From the above formula , we have
[Rounded to the nearest tenth.]
Hence, the measure of the angle = 2.7 radians.

Given:
The graph of a function is given.
To find:
The range of the graph.
Solution:
We know that, the domain is the set of input values and range is the set of output values.
In a graph, domain is represented by the x-axis and range is represented by the y-axis.
From the given graph it is clear that there is an open circle at (-8,-8) and a closed circle at (3,4). It means the function is not defined at (-8,-8) but defined for (3,4).
The graph of the function is defined over the interval . So, the domain is (-8,3].
The values of the function lie in the interval . So, the range is (-8,4].
Therefore, the range of the function are all real values over the interval (-8,4].
