Answer:
Step-by-step explanation:
a= b^c << === >> logb(a) = c
a b c
Convert 45 = 9^√x << === >> log9 (45) = √x
1.7324867604 = √x
3.0 = x squared both sides
I used a log calculator on the internet when a Gaggled log calculators
Answer:
W=8

I think I know what you might be asking for but could you lease clarify because the question is a bit hard to read.
Answer:

Step-by-step explanation:
The line is shown in the attachment.
The slope of this line is given by: 
The line passes through (0,1) and (1,5)
Plug in the points to get:

The equation of this line is given by
, where b=1 is the y-intercept.
From the graph the y-intercept is 1, because the line intersects the y-axis at (0,1).
Therefore the equation is 
B is the right anwser. Hope i helped thanks
