Answer:
The first choice, .
Step-by-step explanation:
is logarithm of
to the base
(the base must be positive.) Raising the base
to a power of
would give
. In other words,
.
If is indeed the inverse of the function
, then
. Apply this property of inverse functions to check each option. By the logarithm property (in this case if
,)
. In other words, the first choice is indeed the inverse of

Answer:
Hence, the answer is 86.42°.
Step-by-step explanation:
We are asked to find how many degrees is the painted spot turning in 0.75 s.
Let us consider that α denote the angle spot is turning in 0.75 sec.
As in 0.75 sec the height of table top is 12.
Hence we can use the trignometric identity to find the measure of angle α.
as
where P denotes the perpendicular i.e. the height of table top.
and B denotes the base i.e. the number of seconds.
Here P=12 and B=0.75
Hence,
