Answer:
(B) only I and II
Step-by-step explanation:
An odd relation is symmetrical about the origin. All of the relations are odd.
An even relation is symmetrical about the y-axis. Only the first two relations are even.
_____
The graph shows the first relation is that of a circle. It is symmetrical about its center at the origin and about any diameter, including the y-axis.
The second relation is a degenerate hyperbola. It graphs as the pair of lines y=x and y=-x. It is symmetrical about both the origin and the y-axis. (It also has other lines of symmetry.)
The third relation is a line with slope -1 (represented by dots). It is symmetrical about the origin, but not the y-axis. It is only an odd relation.
Answer: The length of STV is about 76.83 in.
Step-by-step explanation:
The length of an arc is given by :-
, where r= radius of the cirle,
is the central angke made by arc.
As per given , Radius of the circle : r= 20 in
Central angle of arc SCV =
Then, Central angle of arc SCV =
Then, the length of the arc STV =
Hence, the length of STV is about 76.83 in.
