1. Observe problem
Solve for the area and Circumference of a circle who's radius is 3 cm
Area for circle formula:
pi*r^2=
9pi
I simplicity is needed, 9 pi is around
28.2743338823cm^2
Circumference for circle formula: 2*pi*r
which is
6pi
if simplicity is again needed, its around
18.8495559215cm
Answer: -42
explanation: you start with the innermost parentheses and work out
Answer:
![n=3](https://tex.z-dn.net/?f=n%3D3)
Step-by-step explanation:
Note that
.
Aha! We see a path to the solution!
We now know that our equation is actually
.
We can divide both sides by
to get
.
By inspection or taking the logarithm base 2 of both sides, we see that
.
So, the answer is
and we're done!
Answer:
The relation is a function!
Your Domain should be...
{-1, 1, 7, 9}
Your Range should be...
{-1, 8, 9}
WHY?
Your domain is always your x-coordinates, which are the first coordinates in a pair.
Your range is always your y-coordinates, which are the second coordinates in a pair.
When listing the points, it's important to remain a relation CANNOT be a function if the x's repeat, so luckily, they do not repeat.
Also, when listing points for your range, remember, if they repeat, you should only count one of the numbers, as you can see from the answer, there was two nines, but instead I put one.
