The human population doubles approximately every 50 years if there were 2.5 million people in 1950 how many people are forecaste

Margarita [4]

The equation that would let us determine the number of people or population at a certain year is calculated through the equation,

A(t) = A(o)(2^(t - 1950)/50)

Substituting the known values,

A(t) = (2.5 million people)(2^(2100 - 1950)/50))

A(t) = 20 million

<em>Answer: 20 million people</em>

What is the square root of 500

noname [10]

500 is not a perfect square number. Therefore, find the factors of 500 with the largest perfect square. In this case, 100 is the largest perfect square number in 500.
$500= \sqrt{500} ^2$

$\sqrt{500}=\sqrt{100*5}$

$\sqrt{500}=\sqrt{100}\sqrt{5}$

$\sqrt{500}=10\sqrt{5}$

If you are simply looking for the calculator result, you will get $22.36$
