Question

A certain forest covers an area of
1800
km2
. Suppose that each year this area decreases by
5.25%
. What will the area be after
11
years?

Answer 1

How would you do this ? @FaiqRaees

Answer 2

@Mehek14 @mayankdevnani @ganeshie8

Answer 3

do you know how to write a general equation ?

Answer 4

Would it sound stupid if i said no .. ?

Answer 5

nope !

Answer 6

don't worry, i'm here

Answer 7

Lol okay thank you !

Answer 8

so the equation is :-
Area=A
decreases by x%
time =t years
It is an exponential equation
\[\large \bf f(x)=A(1-x)^t\]

Answer 9

where f(x) is the area after `t` years

Answer 10

just plug the values and solve it.

Answer 11

Okay but what is A and x ?

Answer 12

A is area
x=decreases in area(in %)

Answer 13

So would it look like f(x) = 1800 (1 - 5.25%) ^ 11

Answer 14

correct !

Answer 15

Yay okay thank you :) I will let you know how it goes. I may have more questions later, is that okay ?

Answer 16

okay :D

Answer 17

I got it right :) They wanted me to round and so the answer was 995 km2
I have another question but i will post it separate @mayankdevnani Is that okay ?

Answer 18

okay !
