Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm
Rubik's Cubes! I love these things...
There are multiple methods to solving the Rubik's cube. My personal favorite (and the best if you are a beginner) is the F2L method, or First Two Layers. The first half is patterns and placement, the rest of F2L consists of algorithms. There are not enough characters allowed to tell you specifically how to solve the Rubik's cube. However, there is a guy on YouTube who very clearly explains specific methods over how to solve it. His name is Noah Richardson. He is probably one of the best at explaining the cube's complexity into easy to understand terms, for beginners.
Glad to see more people getting interested into the Rubik's Cube again!
Have a good one!
Answer:
D) 0
There is 1 real solution.
Step-by-step explanation:
Hi there!
This is written in standard form:
This means:
a=9
b=30
c=25
The discriminant states:
If D>0, there are 2 real solutions.
If D=0, there is 1 real solution.
If D<0, there are 2 complex solutions.
Plug in the values:
Therefore, there is 1 real solution.
I hope this helps!
Answer:
The uses of flowcharts are numerous in industries, such as entertainment, engineering, physical sciences, and computer programming. The purpose of flowcharts are to communicate how a process works or should work without any confusing technical jargon, if i have answered your question incorrectly i truly apologize but there isn't much to your question.
