when x is the number of years after 1990, the world forest area (natural forest or planted stands) as a percent of land area is given by f(x) = -0.053x + 34.61. what will the percent be in the year 2005?
○ 70.9%
○ 34.3%
○ 71.7%
○ 33.8%

Explanation:

Step1: Calculate x (years after 1990)

$x = 2005 - 1990 = 15$

Step2: Substitute x into F(x)

$F(15) = -0.053\times15 + 34.61$

Step3: Compute the result

$F(15) = -0.795 + 34.61 = 33.815 \approx 33.8\%$

Answer:

33.8%
