are the 3 that are correct.
Answer:
The slope is 0.
Step-by-step explanation:
slope formula: 
Given points: (-1, 2), (3, 2)
(-1, 2) = (x1, y1)
(3, 2) = (x2, y2)
To find the slope, input the given points into the formula used to find slope:
Simplify:
2 - 2 = 0
3 - (-1) = 3 + 1 = 4
The slope is 0.
Hope this helps :)
Exact form:
1220014151548416
Decimal form:
1.22001415*10^15
If y is 7, x is 2. If y is 9, x is 4. Therefore the domain is {2,4}
Answer:
The notebooks are still hazardous because the Curies didn't use protective equipment (nor did they have it) and the close proximity of the radioactive isotopes allowed for spreading of radioactivity. Since Radium-226 was kept in bottles and drawers in the Curies' home, it was in close proximity to their items. This allowed for Radium-226 to radiate to other items. In turn, those items absorbed the radiation and become radioactive. Today, Marie Curie is buried under a lead-lined coffin and her belongings can be visited ONLY with protective gear and signing a liability form.
