The parent isotope percent will change from 100% to 50% to 25% to 12.5% and to 6.25%. So the sample go through four times of half-life. So the sample is 58*4=232 years old.
STEM is an acronym meaning
Science
Technology
Engineering
Mathematics
One of the main focuses of STEM courses is on science, so you will be learning about various types of science
This is an approach at learning to have students learn all four types of subjects in one class, based on real world applications.
Answer:
8.75 × 10³
Explanation:
Multiply the coefficients and the exponential terms separately; then multiply them together
2.5 × 3.5 = 8.75.
When you multiply exponential terms, you add the exponents.
10¹⁰ × 10⁻⁷ = 10⁽¹⁰⁻⁷⁾ = 10³
The product is 8.75 × 10³.
A scientific calculator does the operation automatically. The buttons may have different labels on your calculator, but the key sequence is usually something like
2.5 Exp 10 × 8.5 Exp +/- 7 = 8.75×10⁻³
A gene is the basic unit of heredity, DNA a self replicating material and chromosome a structure of nucleic acids and protein.
There is no transfer of energy in the reaction.
