Answer:
a becomes a/2 in exponential decay factor.
Step-by-step explanation:
We have to explain what does half-life mean in exponential decay
The general function of exponential decay is
Here, a is the initial value
And when the initial value gets half is known as half life in exponential decay
b is the decay factor in the formula
After half-life a becomes a/2
A matrix is diagonal if
In other words, you want non-zero elements only when the indices of the row and the column are the same: the first element of the first row must be non zero, the second element of the second row must be non-zero, and so on. All other elements must be zero.
