Year CBU Tuition 2 3995 5 5000 8 6200 11 7450 14 8855 17 10420 20 12160   A scatter plot for the data and a graph of a linear model in black and a quadratic model in red follows. 3691215182140005000600070008000900010000110001200013000 Use the above scatter plot to decide which model better fits the data. none quadratic linear Let C(t)C(t) be the cost of tuition at CBU in dollars for t years since 1990. A  quadratic  model for the data is C(t)C(t)  =    . Use three decimals in your answer. Estimate the tuition in 2016. $Use the model to predict the year in which the tuition will be$15325. bobbie71G 2021-09-22 Answered

### India is currently one of the world’s fastest-growing countries. By 2040, the population of India will be larger than the population of China. by 2050, nearly one-third of the world’s population will live in these two countries alone. The exponential function $$\displaystyle{f{{\left({x}\right)}}}={574}{\left({1.026}\right)}^{{x}}$$ models the population of India, f(x), in millions, x years after 1974. Find India’s population, to the nearest million, in the year 2055 as predicted by this function. Efan Halliday 2021-09-20 Answered
