Answer:
c, d and f are rational numbers
Step-by-step explanation:

Answer:
A
Step-by-step explanation:
Given the inequality :
v + 4 > 2 and 8v - 20 < 36
v + 4 > 2
v > 2 - 4
V > - 2
8v - 20 < 36
8v < 36 + 20
8v < 56
v < 56/8
v < 7
Hence,
v > - 2 and v < 7
-2 < v < 7
Option B:
sin x = 1 is the equation represented by the intersection of the graph.
Solution:
The graph lies between -1 and 1 in y-axis.
x-axis of the graph is all real numbers.
The graph oscillates between -1 and 1 and a shape that repeats itself every 2π units.
That is the domain of the graph is all real numbers.
The range of the graph is [-1, 1].
It clearly shows that, it is the graph of sinx = 1.
Hence sin x = 1 is the equation represented by the intersection of the graph.
Option B is the correct answer.
