Can someone with these questions? ?
oceans :
keep worldwide temperatures constant
reduce atmospheric co2
minimize rapid temperature fluctuations
all of the above
about 96% of sea water is made of:
nitrogen
carbon dioxide
sodium and chloride
hydrogen and oxygen
salinity:
is expressed in parts per 1,000
refers to the amount of dissolved particles in sea water
is denoted by the symbol ‰
all of the above
about 330 million cubic miles of water cover the earth.
true
false

1) All the options are true, large masses of water help to regulate the temperature, control temperature fluctuations and reduce the atmospheric CO2-

2) The "common" water is made of H2O, this means that it is made of hydrogen and oxygen, so the right answer is the fourth option.

3) Salinity is expressed in (gr of salt)/(kg of water), so is expressed in parts per 1000, it refers to the amount of dissolved salt in water (not any particle, and not only in seawater, so the option 2 is wrong)

and is represented by the sign %, which means percent.

So the only correct option is the first one.

4) True, it's around 333 million cubic miles of water.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
