I believe the answer is 0.9 because a significant figure is a similar difference
THE ANSWER IS C
step by step explanation
2x - y = 5 also equals 4x - 2y = 10
4x-2y=10
+3x+2y=4
7x = 14
x = 2
2(2) - y = 5
-y = 1
y = -1
so, B. (2,-1)
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
