7. Technology required. The population of Mali can be represented by m(t) = 17. e(0.031) The population of Saudi Arabia can be represented by s(t) = 31 e(0.015). In both models, t represents years since 2014 and the populations are measured in millions. a. Which country had a higher population in 2014? Explain how you know. b. Which country has a higher growth rate? Explain how you know. c. Use graphing technology to graph both equations on the same axes. d. Do the two graphs intersect? If so, estimate their point of intersection and explain what it means in this situation. If not, explain what it means that the two graphs don't intersect.
