Electrical wires suspended between two towers form a catenary (see figure) modelled by the equation shown below, where x and y are measured in meters. y = 20 cosh(x/20) ? 20 ? x ? 20 the towers are 40 meters apart. find the length of the suspended cable. (round your answer to three decimal places.)

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.
