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
Answer:
200
Step-by-step explanation:
Surface are of cube = 6a^2
Answer:
523.33 mm³
Step-by-step explanation:
The volume (V) of a sphere is calculated using the formula
V = 
πr³ ← r is the radius = 5, thus
V = π × 5³
= 
≈ 523.33 mm³
Answer is D bc I did allot of math to figure this out and I did it and I got it right.
