P (in millions) = 250 x 2^( y-1990)/66

What was the approximate population of the United States in 1960?
p=250x2^-.4545

How do i figure this out from here

2^(-.4545) = 0.729763045

Put 2^(-.4545)into the Google search window, and the google caculator will do it for you.

If you want to do the entire thing, put this in the search window:

250*2^(-.4545) or even this...

250*2^((1960-1990)/66)
Nice.

2^(-.4545) = 0.729763045

Put 2^(-.4545)into the Google search window, and the google caculator will do it for you.

250*2^((1960-1990)/66)
Nice.

To determine the approximate population of the United States in 1960 using the given formula, you need to substitute the year into the equation and solve for the population (P).

First, calculate the exponent part of the equation:

y - 1990 = 1960 - 1990 = -30

Next, substitute this value into the equation:

P = 250 * 2^(-30/66)

To solve this equation, you can either use a calculator or the Google search window.

To use the Google search window, type in "2^(-30/66)" or "250*2^(-30/66)" and press enter. The Google calculator will provide the result.

Alternatively, you can use a scientific calculator or an exponent calculator to perform the calculation manually.

Once you have the result, you will have the approximate population of the United States in 1960 (P in millions).
