Based on these conjectures we describe a variety of multiplicative units, then propose three ways of understanding rate of change in relation to exponential functions. Finally we argue that rate is ...

The rate of reaction can be analysed by plotting a graph of mass or volume of product formed against time. The graph shows this for two reactions. The steeper the line, the greater the rate of ...

A group of scientists have refined the famous 'hockey-stick' graph, adding nearly 10,000 years of data onto it, and highlighting the alarming trend in global warming in the past few decades. This new ...

Science calculations - calculating rates Rate changes show how quickly something is happening. The rate of change can be calculated using this equation: ...

VERDICT False. The “hockey stick” graph is not false evidence of man-made climate change. It shows temperatures rapidly rising since the 20th century.
