Answer:
is not a logarithmic function because the base is equal to 1.
Step-by-step explanation:
A logarithmic function is of the form: 
For a logarithmic function to exist, we must fulfill certain conditions. The conditions are
i. The base,
, is greater than 0. 
ii. The base,
, is not equal to 1. 
iii.
must be greater than 0. 
Now, if we observe all the choices given, we conclude that the third choice is correct as the base there is 1. If base is equal to 1, then it violates the definition of logarithmic functions. So, the correct choice is:
is not a logarithmic function because the base is equal to 1.
Answer:
Time taken by the un powered raft to cover this distance is T = 192.12 hr
Step-by-step explanation:
Let speed of boat = u 
Speed of current = v 
Let distance between A & B = 100 km
Time taken in downstream = 32 hours


u + v = 3.125 ------ (1)
Time taken in upstream = 48 hours


u - v = 2.084 ------- (2)
By solving equation (1) & (2)
u = 2.6045 
v = 0.5205 
Now the time taken by the un powered raft to cover this distance

Because un powered raft travel with the speed of the current.

T = 192.12 hr
Therefore the time taken by the un powered raft to cover this distance is
T = 192.12 hr
Answer:
O y > 4
Step-by-step explanation:
The dotted line indicates the line is not part of the inequality, and it is clearly greater than 4.
