Use a calculator with a \( y^{x} \) key or a \( \square \) key to solve the following. The exponential function \( f(x)=548(1,032)^{x} \) models the population of a country, \( f(x) \), in millions, \( x \) years after 1970 . Complete parts (a) - (e) . Substitute 0 for \( x \) and, without using a calculator, find the country's population in 1970 The country's population in 1970 was \( \square \) million.

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations \( A \) and \( B \), which are 47 miles apart. When the satellite is on one side of the two stations, the angles of elevation at \( A \) and \( B \) are measured to be \( 87^{\circ} \) and \( 84^{\circ} \), respectively. How far is the satellite from station A? How high is the satellite above the ground?
