Ihave this question in geometry that i need with, can you me solve it? find the coordinates of the midpoint of a segment having the given endpoints. q(1, -3), r(11, 5)

Just tell me how to set up the equation.

Do some research and find a city that has experienced population growth. determine its population on january 1st of a certain year. write an exponential function to represent the city’s population, y, based on the number of years that pass, x after a period of exponential growth. describe the variables and numbers that you used in your equation.

For what value of (y) is 3^3/3^y =1/9
