Answer:
C
Step-by-step explanation:
Look for the case in which every input is unique (no repetitions).
A does not qualify, as 3 appears as an input twice.
B does not qualify, for the same reason
C qualifies (is a function), because all the inputs {1, 2, 3, 4} are unique.
D does not qualify (see A, above).
Answer:
csc (0°) and sec (90°) are not defined.
Step-by-step explanation:
Given the options wehave to select the option which is undefinesd
First option: sec 45°

which is defined
Second option: csc(0°)

which is not defined
Third option: sec(90°)

which is not defined.
Hence, option 2 and 3 are not defined.
Use proportionals to find y.

Answer:y=12
The equation out of this is; what is 250/100 of a number x = 90?
=> Division of 250 by 100 gives 2.5.
=> Now multiply 2.5 by a number x resulting to 2.5x on the L.H.S.
=> make x the subject and come up with x = 90/2.5.
answer is 1/36.
