Instead of subtracting 6 from 12 then dividing they added 6 to 12 & ended up with 18. 18 by 2 is 9.

Elden [556K]

Answer:

The statement is correct

see the explanation

Step-by-step explanation:

we know that

The equation of a exponential growth function is equal to

y=a(1+r)^x

where

y  is the area covered by the plant in percentage

x is the time in years since 2000

r is the rate of change

a is the initial value

In this problem we have

r=200\%=200/100=2

a=0.2\%

substitute the values

y=0.2(1+2)^x

y=0.2(3)^x

In the year 2005

x=2005-2000=5\ years

substitute the value of x in the exponential function

y=0.2(3)^5=48.6\%

48.6% is about 50%

therefore

The statement is correct

So you would loom at the 1, keep in mind that any number lower than 5 toy round down. so the answer would be 50. Now consider the number 57 you would round up because 5 or greater you would round up so it would be 60.

Help Me Please.................

Your answer would be x = -15.8994.

To get this, you first add 7 to each side making the equation -4.818 = x/3.3

Then, you would need to multiply each side by 3.3 to get x by itself.

Your answer would be -15.8994.
