x = \frac{2}{7}\,m + \frac{10}{21}\,m

x = \frac{42}{147}\,m + \frac{70}{147}\,m

x = \frac{112}{147}\,m

The population of an endangered bird was about 230,000 in 2001. The equation y= 200,000(0.75)^x describes the bird la population
mart [117]

Answer:

634

Step-by-step explanation:

The population of the birds in 2001 = 230000

From 2001 to 2021 = 20 years

Given:

y = 200000(0.75)^{x}

where x is the number of years since 2001.

The population of the birds after 20 can be determined by;

y = 200000(0.75)^{20}

  = 200000(3.171211939 x 10^{-3})

  = 634.2424

y = 634

Thus, there would be 634 endangered birds in 2021.
