Answer:
The area after 9 years will be 1,234 km^2
Step-by-step explanation:
In this question, we are tasked with calculating what the area of a certain forest that decreases at a certain percentage would be after some years.
To answer this question, we shall be using an exponential approximation.
Now, to use this exponential approximation, we shall be needing a supporting exponential mathematical equation.
This can be written as;
A = I(1-r)^t
where A is the new area we are looking for
I is the initial area which is 1700 according to the question
r is the rate of decrease which is 3.5% = 3.5/100 = 0.035
t is time which is 9 years according to the question
We plug these values and have the following;
A = 1700(1-0.035)^9
A = 1700(0.965)^9
A = 1,233.66
This is 1,234 km^2 to the nearest square kilometer
I don’t think any of them are right
The bisector of an angle is a segment or a ray that passes through the vertex and splits it into two congruent angles.
Hope this is of great help to you, and happy studying~!

Answer:
all of them are much larger except number 2 which is close to 1
Step-by-step explanation:
Answer:
Step-by-step explanation:
We have:
$log_{10} (10)=1$
$\therefore \log_{10}(2\times 5)=1$
$\implies \log_{10}(2)+ \log_{10}(5)=1$
$\implies \log_{10}(5)=1-\log_{10}(2)$
$\implies \log_{10}(5)=1-0.3010=\boxed{0.6990}$
