From 1790 to 1860 , the United States population, in thousands, is modeled by the equation P=4000(1.031)t where t is the number of years since 1790 .a. About how many people were living in the U.S. in 1790? What about in 1860 ? Show your reasoning.
Q. From 1790 to 1860 , the United States population, in thousands, is modeled by the equation P=4000(1.031)t where t is the number of years since 1790 .a. About how many people were living in the U.S. in 1790? What about in 1860 ? Show your reasoning.
Calculate Initial Population: To find the population in 1790, we need to calculate P for t=0, since 1790 is the starting point of our model.We use the equation P=4000(1.031)t and substitute t with 0.P=4000(1.031)(0)Since any number raised to the power of 0 is 1, we have:P=4000×1P=4000
Calculate Population in 1860: To find the population in 1860, we need to calculate P for t=70, since 1860 is 70 years after 1790.We use the equation P=4000(1.031)t and substitute t with 70.P=4000(1.031)70Now we calculate (1.031)70 using a calculator.(1.031)70≈6.144So, P≈4000×6.144P≈24576
