Answer:
A hope its right!!
Step-by-step explanation:
Have a good day!
Just divide 78 billion by 78 thousand
That's how I would graph it...
Answer:
I believe the answer would be B) x^2 - 16x + 64 = -21 + 64
Step-by-step explanation:
When you're completing the square you take the "middle" term (in this case it's -16) and you divide it by two, then square it. By doing that for this problem you get 64 (16/2 = 8 - 8^2 = 64; signs don't matter in this case because you multiply 2 negatives). You have to add that 64 to BOTH sides so that the equation evens out.
Ultimately, with it factored, the answer will be (x-8)^2
Using proportions, it is found that the central angle of the walking sector is of 36º.
- This question can be solved by <em>proportions</em>, using a rule of three.
- The angle corresponding to 100% = 1 is of 360º, while we want to find the angle corresponding to the walking sector, which is of 10% of the circle.
Hence, the <em>rule of three</em> is:
1 - 360º
0.1 - x
Applying cross multiplication:

The central angle of the walking sector is of 36º.
