Answer:
The domain is [0,25] and the range is [0,20]
Step-by-step explanation:
The domain is the range of numbers and that the x value can be in the graph. The range is the range of numbers that the y value can be in the graph.
For the domain, the lowest x value you have is zero in the biggest x value is 25. since there is a dot when x is 25 and when x is 0 your answer is in brackets.
For the range, the lowest y value is 0 and the highest y value is 20. once again your answer is in brackets because there is a point when y is 0 and when y is 20.
Answer:
25.48 days
Step-by-step explanation:
For a radioactive substance, the Amount of the substance remaining A(t) is modeled by the equation

where

In the given problem:
Half Life of the Radioactive Isotope = 8
Initial Amount,
=100%=1
A(t)=11% =0.11
Therefore substituting in the model above:

The farmer need to wait for 25.48 days
using pythagorean theorem
a^2 + b^2 =c^2
a^2 +8^2 =14^2
a^2 +64 = 196
subtract 64 from each side
a^2 = 132
take the square root of each side
a^2 = sqrt (132)
a=11.48912529
a =11.5
