If I've read this correctly, it looks like this.

If that is correct, then the first step is to put the top part of the denominator over 3x
The next part is to flip a three tier fraction. I'm afraid I have to show what happens. My latex is not that strong.
What you get is

This is just about your final answer. You could write it as

Recall that a relationship is a function ONLY IF for each input (x-) value there is exactly one corresponding y value. More than that? Then the relationship is not a function. That applies to the first and the third relations given here.
The second relationship is a function.
Answer:
So heres what I think
C=2pie r
C=2*3.14*4
c=25.12
So basically half the circle is the radius and the whole is the circumference. So what you are doing is changing pie to 3.14 (since pie=3.14), since half the circle its radius so all you have to do is 2 times 3.14 times 4 to get 25.12 as your circumference.
Hope this helps!
Step-by-step explanation:
To find the effective interest rate the formula is
R=(1+r/k)^(k)-1
R=?
r=nominal Interest rate 0.1364
K=compounded daily 365
Plug in the formula
R=(1+0.1364÷365)^(365)−1
R=0.1461 This the effective interest rate 14.61%
As you can see that the effective interest rate is greater than the nominal interest rate by
0.1461−0.1364=0.0097×100=0.97%
So the answer is a
