PLZ HELP WORTH A LOT OF POINTS AND I HAVE 10 MINUTES!!!!A certain forest covers an area of 1700 km^2. Suppose that each year this area decreases by 3.5%. What will the area be after 9 years? Use the calculator provided and round your answer to the nearest square kilometer.
Answers
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: 4
explanation: it would be 4 because slope is rise/run and it rises 4 and runs one so u would get 4/1 which is 4 simplified. :)
Answer:
Slope: 4
Step-by-step explanation:
The slope is 4, because each time x is increased by 1 y is increased by 4.
The rise would be 4 and the run would be 1.
Since the slope of a graph can be found by dividing rise by run, the slope would be 4/1, which is equal to 4.

Step-by-step explanation:
(4y−5)^2+80y
Use binomial theorem (a−b)^2=a^2−2ab+b^2 to expand (4y−5)^2.
16y^2−40y+25+80y
Combine −40y and 80y to get 40y.
