The rapid growth rate of Moso bamboo makes it an environmentally important plant, as it stores massive amounts of carbon dioxide (CO2). Each year, one hectare of Moso bamboo in China
absorbs 5.1 tons of carbon dioxide, which can compensate for the annual CO2 emissions of 3
people. Which of the following equations best models the number of hectares, h, of Moso
bamboo that must be planted to compensate for the annual CO2 emissions of 100 people in
China?

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

2,160 π
