Suppose that the world's current oil reserves is R1960 billion barrels. If, on average, the totalreserves is decreasing by 19 billion barrels of oil each year, answer the following:=A.) Give a linear equation for the total remaining oil reserves, R, in terms of t, the number ofyears since now. (Be sure to use the correct variable and Preview before you submit.)R=B.) 11 years from now, the total oil reserves will bebillions of barrels.C.) If no other oil is deposited into the reserves, the world's oil reserves will be completelydepleted (all used up) approximatelyyears from now.(Round your answer to two decimal places.)

The value of all goods and services produced in a nation during a specific period of time, as compared to an earlier period, is called the economic growth rate. It measures the change in a nation's gross domestic product (GDP). The United States had an economic growth rate of approximately 2.9%and GDP of approximately $20.58 trillion in 2018. If the economic growth rate is expected to stay the same for the next 3 years, what is the projected GDP for the year 2021? a $21.96 trillion b $23.15 trillion c $22.42 trillion d $22.31 trillion
In 1967, the population of Clements, PA was 7,000, and in 1974 the population was 12,000. Should the populatio grow linearly, in what calendar year (to the nearest whole calendar year), would it reach 50,000? If instead the population grew exponentially, how many fewer years would it take to reach 50,000?
Algeria is a developing country on the northern coast of Africa. Its infant mortality rates (number of deaths per 1000 live births) declined from 94 in 1980 to 33 in 2006.a.
