A certain forest covers an area of 3900 km^2. Suppose that each year this area decreases by 6.75%. What will the area be after 12 years

1686

Step-by-step explanation:

Rate of reduction = 100 - 6.75 = 93.25%

After 12 years, the reduction in trees = 0.9325^12 = 0.432301

Area after 12 years = 3900 x  0.432301 = 1686

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
