Answer: inverse of given function = log(x)/log(3)
Step-by-step explanation: how to find the inverse of any function?
in the complete function, replace y with "x" and x with "y"then, solve the obtained equation from step 2 for yand, then the value obtained for "y" is the inverse required i.e. = f^{-1}(x)
now, we solve the problem:
given : - y = 3^x
replacing the value of "y" with "x", we get,
x = 3^y
to solve for "y" we should take the "logarithm" for both sides
log (x) = y log(3)
or y = log(x)/log(3)
or f^(-1) (x) = log(x)/log(3)

As the sine rule states,
A/sina = B/sinb = C/sinc .
in the diagram, there are two identified sides and if you use the sine rule, you can find the opposed angles easily.
there are:
side a, with angle â .
side b, with angle b.
so the answer is C.
if you input these into the sine rule, it would be:
a/ sin a = b/sin b
Answer:
the answer is B

Answer:
The total amount paid by Jill = $ (3 d)
Step-by-step explanation:
Here, the cost of 1 book = $ d
Now, the number of books purchased by Jill = 3
So, the total cost of 3 books = 3 x ( Cost of 1 book)
= 3 x ($d) = 3 d
So, if Jill purchased 3 books, the total amount paid by her = $ (3 d)
