List three numbers that are between -21 and -12

15m is what percent of 60m; 3m; 30m; 1.5 km? the last one is km not m

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.

Find the solution on the interval [0, 2pi)
