In chemistry, a buffer system is a type of solution that is able to resist changes in its pH when small amounts of an acidic or basic substance is added to it

<h3>What is a buffer system?</h3>

In practice, a buffer solution contains either a weak acid and its conjugate base or a weak base and its conjugate acid.

An important example of a buffer system is blood, which acts as a buffer inside the human body to maintain a pH between 7.35 and 7.45.

There are various other examples of buffer solutions, including The phosphate buffer system (which also occurs in the cells of the body) Buffer of acetic acid (weak acid) with sodium acetate.

Note that the question is incomplete, hence a general overview was stated to guide you.

True or False: Suppose a firm's CFO thinks that an externality is present in a project, but that it cannot be quantified with an
GarryVolchara [31]

Answer:

False

Explanation:

Suppose a firm's CFO thinks that an externality is present in a project, but that it cannot be quantified with any precision ¾ estimates of its effect would really just be guesses. In this case, the externality should be ignored ¾ i.e., not considered at all ¾ because if it were considered it would make the analysis appear more precise than it really is. This is a false statement.

You want to buy your dream car which will cost you $5900. If you could invest your entire savings of $3500 at an annual interest
Liula [17]

Answer:

t = 4.607742347 years rounded off to 4.61 years

Explanation:

To calculate the number of years it will take an investment of $3500 to grow to $5900 at an annual interest rate of 12%, we will use the formula for the future value of cash flows. The formula can be written as follows,

Future value = Present value * (1+i)^t

Where,

  • i is the interest rate
  • t is the time in years

Plugging in the values for future value, present value and i, we can calculate the t to be,

5900 = 3500 * (1+0.12)^t

5900 / 3500 = (1.12)^t

1.685714286 = 1.12^t

Taking log on both sides.

Ln(1.685714286)  /  Ln(1.12)  =  t

t = 4.607742347 years rounded off to 4.61 years

The expected rate of return for a stock whose next dividend is "DIV1", that has a required rate of return "r" and expects to gro
Tema [17]

Answer:

The correct answer is r=(DIV1/P0)+g

Explanation:

The expected rate of return for a stock is usually the dividend yield  added to capital gains yield.

Dividend yield is the percentage of the share's price that the company pays to shareholders as dividends and the formula is the dividends divided by the share price, hence in this scenario it DIV1/PO

On other hand,capital gains yield is the percentage increase of the share price over time. In other words, the share price growth rate,which is a market expectation of the company's performance.The g given in the question depicted this.

Without mincing words,the expected rate of return on the stock is dividends yield(DIV1/P0) plus the capital gains yield(g)

garri49 [273]

Answer:

$47439.50

Explanation:

For a single tax payer if your taxable income range is $200,000 - $500,000 then your income tax is $45,689.50 + 35% of amount over $200,000 of taxable income.

Income tax liability = $45689.50+{ 205000-200000)×35%}

$45689.50+(5000×35/100)

$45689.50+(5000×0.35)

$45689.50+1750

= $47439.50

The income tax liability will be $47439.50
