Using an exponential function, it is found that the half-life of the substance is of 5.23 units of time.
<h3>What is the exponential function for the amount of a substance?</h3>
The function is given by:
In which:
- A(0) is the initial value.
- k is the exponential decay rate.
The parameters are given by:
A(0) = 48, k = 0.1325.
Hence the equation is:
The half-life is the amount of time for which A(t) = 0.5A(0) = 24, hence:
t = 5.23.

Answer:
11 inches
Step-by-step explanation:
hypotenuse² = leg₁² + leg₂²
=10² + (√21)²
= 100 + 21
= 121
Hypotenuse = √ 121 = √11*11 = 11 inches

Step-by-step explanation:
Answer:
19/30
Explanation:
1. Exchange them to a common factor which happens to be 30 for both of them
2. Multiply by that factor on both the top and bottom to get the number equivalent to a fraction of that category
3. Subtract
4. Simplify, however in this case simplification isn't doable.
