After 500 years one would have N nuclei of the original substance.
N = 100 * exp ( -ln(4) ) = 25
LOL.
I guess it is exp( - lamda * t)
Lamda, the decay constant is the ln(2) over the half life.
So we get exp( -ln(2)/250 * 500) or exp ( -ln(4) )

An equation written in slope-intercept form is y=mx+b, where m is a constant equal to the slope. Parallel lines have the same slope. So a line parallel to y=-2x+3 is y=-2x+5. Perpendicular lines have slopes which are negative reciprocals of each other. So a line perpendicular to y=-2x+3 is y=1/2x+7. y=2x-1 is neither parallel of perpendicular to y=-2x+3.
Answer:
8:9 = eight to nine
Step-by-step explanation:
16:18 - divide each by 2 in order to simplify
= 8:9
That means:
1) you cannot factorize it, or
2) the binomial is not the right one to be the quotient or
3) the roots of the binomial are not the roots of the polynomial
