Answer:
Quadratic polynomial is x^2 - x - 20
Answer: the mass of a neutron is approximately 2,000 times the mass of an electron
Step-by-step explanation:
- the easiest way to solve this (in my opinion) is to simply divide the mass of a neutron by the mass of an electron
- 
= 
= 
≈ 
≈ 
≈ which is approximately 2222
- so 2222 is approximately 2000 times
- therefore, the mass of a neutron is approximately 2,000 times the mass of an electron
hope this helps :)

Answer:
2√41 ≈ 12.81 units
Step-by-step explanation:
The distance between two points is conveniently found using the distance formula:
d = √((x2 -x2)^2 +(y2 -y1)^2)
d = √((-3-5)^2 +(8-(-2))^2) = √(64 +100) = 2√41 ≈ 12.81 . . . units
