Answer:

-1

Explanation:

Find components of the definition.

$f(x+h)=-h-x+1\\f(x)=-x+1$

Plug in components

$\frac{f(x+h)-f(x)}{h} = \frac{-h-x+1-(-x+1)}{h}$

Simplify.

Describe how differences in water temperature and salinity affect deep water currents.

Virty [35]

When the water molecules of the ocean become heated, they expand. ... Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity. To relate this to ocean currents, the higher the salinity of ocean water, the more dense it becomes. THIS IS NOT FROM MY OWN WORDS, IF YOURE TYPING THIS DOWN PLEASE REPHRASE IT A BIT!! :)

Does (1, 0) make the equation y = 7x true?

LenaWriter [7]

Well, from what I know, I believe that it does not. I don't see how it's possible, if y = 7, how does this relate to (0,1), I don't see how it's would be possible. My guess, it would impossible.

If 50. 0 g of ch₃oh (mm = 32. 04 g/mol) are added to a 500. 0 ml volumetric flask, and water is added to fill the flask, what is

Elza [17]

Taking into account the definition of molarity, the concentration of CH₃OH in the solution is 3.12 $\frac{moles}{liters}$ .

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

$Molarity=\frac{number of moles}{volume}$

Molarity is expressed in units $\frac{moles}{liters}$ .

<h3>Concentration of CH₃OH</h3>

In this case, you know:

number of moles= 50 g× $\frac{1 mole}{32.04 g}$ = 1.56 moles, being 32.04 $\frac{g}{mole}$ the molar mass of CH₃OH
volume= 500 mL= 0.5 L (being 1000 mL= 1 L)

Replacing in the definition of molarity:

$Molarity=\frac{1.56 moles}{0.500 L}$

Solving:

<u><em>Molarity= 3.12 </em></u> $\frac{moles}{liters}$

Finally, the concentration of CH₃OH in the solution is 3.12 $\frac{moles}{liters}$ .
