What toothpick design number could build with exactly 82 toothpicks?

The graph below could be the graph of which exponential function?

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

Solve the equation - 2(m -30) = -6m a-15 b-13 c-8 d8
