Acertain forest covers an area of 3800 km^2. suppose that each year this area decreases by 7.25%. what will the area be after 8 years

The area of forest after 8 years , decreases at the rate of 7.25% is 2081.108 square kilometers  .

Step-by-step explanation:

Given as :

The initial area of forest = 3800 square kilometer

The rate of decrease of area every year = r = 7.25 %

The time period for its decrease = t = 8 years

Let The forest area after 8 years = A square kilometers

Now, According to question

The forest area after 8 years = Initial area of forest ×

or, The forest area after 8 years = 3800 km² ×

or, The forest area after 8 years = 3800 km² ×

Or, The forest area after 8 years = 3800 km² ×

Or, The forest area after 8 years = 3800 km² × 0.54766

Or, The forest area after 8 years = 2081.108 km²

So, Area of forest after 8 years = 2081.108 km²

Hence The area of forest after 8 years , decreases at the rate of 7.25% is 2081.108 square kilometers  . Answer

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
