Carbon credits are used to
a. rehabilitate tropical rainforests
b. reduce the emission of volatile organic compounds (voc s)
c. regulate how much carbon dioxide a country can emit
d. coordinate carbon sequestration activities

Answer is: c. regulate how much carbon dioxide a country can emit.

Carbon credits is a component of national and international attempts to lower the growth in concentrations of greenhouse gases.

One carbon credit is equal to one tonne of carbon dioxide.

Carbon credit is a certificate showing that a government or company has paid to have a certain amount of carbon dioxide removed from the environment or permit that allows the holder to emit one ton of carbon dioxide.

Carbon credits are used to reduce the emission of volatile organic compounds (VOC s).Sometimes called as ‘carbon offset’ because it brings up CO2 (carbon dioxide) or CO2e (carbon dioxide equivalent gases) which are removed from the atmosphere from an emission.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
