Energy consumption in a particular country in quadrillion BTUS can be modeled by C(x) = - 0.014x + 1.295x+ 68,958, where x is the number of years after 1970.
a. One solution to the equation 89.258 = - 0.014x+ 1.295x+68.958 is x = 20. What does this mean?
b. Graphically verify that x 20 is a solution to 89.258 = - 0.014x+1.295x + 68.958.
c. To find when after 2020 the energy consumption in that country will be 89.258 quadrillion BTUS according to the model, is there a need to find the second solution to this equation?
Why or why not?
a. Choose the correct answer below.
O A. In 1990, consumption was 68.958 quadrillion BTUS.
O B. In 2020, consumption was 68.958 quadrillion BTUS.
O C. In 1990, consumption was 89.258 quadrillion BTUS.
O D. In 2020, consumption was 89.258 quadrillion BTUS.
