a certain forest covers an area of 4800km squared. if each year the area decreased by 6.75%what will be the area after 11 years
Sunny_sXe [5.5K]

<u>Answer-</u>

The area after 11 years will be 2225.28 km²

<u>Solution-</u>

This can be represented as exponential decreasing function,

y=a(1 - r)^t

Where,

  • a = starting amount
  • r = rate
  • t = years

Putting the values,

y=4800(1-0.0675)^{11}

\ =4800(0.9325)^{11}

\ =4800\times 0.4636

\ =2225.28

Therefore, at this rate the area of the forest after 11 years will be 2225.28 km².

Responda: Por favor, é urgente.
kumpel [21]

Answer:

C) CA=40

Step-by-step explanation:

2y/(2y+4)=(2y+6)/4y

cross multiply

8y²=4y²+20y+24

4(2y²)=4(y²+5y+6)

divide both sides by 4

2y²=y²+5y+6

y²-5y-6=0

(y-6)(y+1)=0

So the answer must be either 6 or -1.  Since it can't be a negative number, it must be 6.

CA=2(6)+4+4(6)

CA=12+4+24

CA=40
