Population Growth Using 20th-century U.S. census data,
asambeis [7]

The population of Ohio will be 10 million in the year 1970

The population growth of Ohio is represented by the function:

P(t)=\frac{12.79}{1+2.402e^{-}0.0309t}

P is the population in millions

t is the number of years since 1900

To find the year that the population of Ohio will be 10 million, substitute P = 10 into the function P(t) and solve for t

10=\frac{12.79}{1+2.402e^{-}0.0309t}\\\\10(1+2.402e^{-}0.0309t)=12.79\\\\1+2.402e^{-}0.0309t=\frac{12.79}{10} \\\\1+2.402e^{-}0.0309t=1.279\\\\2.402e^{-}0.0309t=1.279-1\\\\2.402e^{-}0.0309t = 0.279\\\\e^{-}0.0309t =\frac{0.279}{2.402} \\\\e^{-}0.0309t =0.116\\\\-0.0309t=ln0.116\\\\-0.0309t=-2.154\\\\t=\frac{-2.154}{-0.0309} \\\\t=69.7

t = 70 years (to the nearest whole number)

70 years after 1900 will be 1970

Therefore, the population of Ohio will be 10 million in the year 1970

<h3>What is the rewritten form of.the expression using the least possible terms?</h3>

It follows from the task content that the given expression is to be rewritten using the fewest terms.

Since the given expression is;

( −2x − 13 ) + ( 19 + 5x )

By getting rid of the parentheses; we have;

-2x - 13 + 19 + 5x

By collecting like terms; we have;

-2x + 5x - 13 + 19

3x + 6

Therefore, the required rewritten form of the given expression is; 3x + 6.
