Answer:
Step-by-step explanation:
in 6 years we know that it will be half, because that's what "half life" means
in 3 years it's only loses 1/2 * 1/2 = 1/4 of it's mass
in 1 year it's only loses 1/6 * 1/2 = 1/12 of it's mass
from that we can make the formula that
current weight of radium = Wr
Mass of radium orginal = Mo
year of time = t ( must be in years, not days, months or weeks )
Wr = (1/12)*t* Mo
Answer:
(1/2, 0)
Step-by-step explanation:
To find the y-intercept, set x = 0 and find y: y = 4(0) - 2 = -2, so that we have the point (0, -2).
To find the x-intercept, set y = 0 and find x: 0 = 4x - 2, or x = 1/2, so that we have the point (1/2, 0). This corresponds to the first answer choice.
