Answer:
y = 2/5x+2
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= (4-2)/(5-0)
=2/5
The y intercept is 2
The slope intercept form is y = mx+b
where m is the slope and b is the y intercept
y = 2/5x+2
Answer:
The equation that describes the amount of mass left after a time t of a radioactive isotope is the following:
where
is the mass of the sample at t = 0
is the half-life of the sample
For the element X in this problem,
We want to find the time t at which
So we need to re-arrange the equation making t the subject:
Step-by-step explanation:
Answer:
22/24
Step-by-step explanation:
To figure this out, both the numerator and the denominator of the equivalent fraction have to be proportional to 11/12.
To do that, multiply the numerator (11) by 2, (because the denominator of the second fraction is 2 times the denominator of the first fraction).
The second, proportional fraction is 22/24.
