Answer:
2%
Step-by-step explanation:
20% takes 10 years to decay
To find per year decay, we divide the percentage by the number of years, so we get unit rate of years {per year]. Thus we have:
20%/10 = 2% per year
It's that simple.
Hence, the percentage by which the substance decays each year is 2%
Answer:

Step-by-step explanation:
x intercept of a function is the point where it's graph intersects the x axis.
or
simply that value x, where the value of y is 0.

<h3>
Answer: 2x/15</h3>
T = total amount of money = (14x^2)/15
y = amount of money each person receives
n = number of people
y*n = T
y*7x = (14x^2)/15
y = (1/(7x))*(14x^2)/15 .... multiply both sides by 1/(7x)
y = 2x/15
