How do they know the Earth is 4 billion years old?
Space and AstronomyAll the data from Earth and beyond has led to the estimated age of 4.5 billion years for our planet. The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. How did geologists find out that the Earth is 4.6 billion years old? It
What is the general form for an exponential function that has an asymptote at y 0?
Space and Astronomyy = 0 is a horizontal asymptote, toward which the graph tends as the x-axis continues to the left. Also note that the graph shoots upward rapidly as x increases. This is because of the doubling behavior of the exponential. In the form y = abx, if b is a number between 0 and 1,
