Write an equation modeling the situation.[c] What would be the car’s value this year?decay factor is 12%, i dont kno the equation but i think its something like y=(12)x <--whats x?and for c i got $3421440002.) The population of a town was 12,000 in theyear 1990. After 1990, the town’s populationgrew at a constant rate of 8% a year.[a] What is the growth factor? Write an equation modeling the situation.[c] What was the population in the year 2000?[d] In the year 2010?[e] In 1980?my answers were:growth factor 5%equation: y=12000(8)x? <--whats x?y=12000(8)10and got a total of 1.288490113 <--but that doesnt look right...am i doing something wrong?3.) You conducted an experiment with a substancewith a half-life of 1 hour. Unfortunately, youforgot to record how much of the substance youstarted out with.
