For altitudes up to 36,000 feet the relationship between ground temperature and atmospheric temperature can be described by the formula t -0.0035a+g, in which t is the atmospheric temperature in degrees fahrenheit, a is the altitude, in feet, at which the atmospheric temperature is measured, and g is the ground temperature in degrees fahrenheit. solve the equation for a. if the atmospheric temperature is -65.5°f and the ground temperature is 57°f, what is the altitude?

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0
