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.

iragen [17]

Answer:

$29.70

Explanation:

Retention ratio = 1 - payout ratio

= ( 1  -0.5 )

= 0.5

Growth rate, g = ROE × Retention ratio

= 0.15 × 0.5

= 0.075

= 7.5%  

Required return = Risk - free rate + [ Beta × (Market rate- risk-free rate) ]

= 2.5% + 1.44 × (11% - 2.5%)

= 14.74%

Intrinsic value = \frac{\textup{D1}}{\textup{(Required return-Growth rate)&#10;}}

=\frac{\textup{2}\times(1+0.075)}{\textup{(0.1474-0.075)&#10;}}

= 29.69 ≈ $29.70

Answer:

P-value for slope coefficient of the size of the mode CuFt is0.00

Explanation:

The slope coefficient is change in probability when all other independent variables are held constant. The output is 93.3 which is due to the variation in labor hours. These variations are due to large number of furniture moved in cubic feet.

Simplifying
(2a + 5)(3a + -4) = 0

Reorder the terms:
(5 + 2a)(3a + -4) = 0

Reorder the terms:
(5 + 2a)(-4 + 3a) = 0

Multiply (5 + 2a) * (-4 + 3a)
(5(-4 + 3a) + 2a * (-4 + 3a)) = 0
((-4 * 5 + 3a * 5) + 2a * (-4 + 3a)) = 0
((-20 + 15a) + 2a * (-4 + 3a)) = 0
(-20 + 15a + (-4 * 2a + 3a * 2a)) = 0
(-20 + 15a + (-8a + 6a2)) = 0

Combine like terms: 15a + -8a = 7a
(-20 + 7a + 6a2) = 0

Solving
-20 + 7a + 6a2 = 0

Solving for variable 'a'.

Factor a trinomial.
(-5 + -2a)(4 + -3a) = 0

Subproblem 1
Set the factor '(-5 + -2a)' equal to zero and attempt to solve:

Simplifying
-5 + -2a = 0

Solving
-5 + -2a = 0

Move all terms containing a to the left, all other terms to the right.

Add '5' to each side of the equation.
-5 + 5 + -2a = 0 + 5

Combine like terms: -5 + 5 = 0
0 + -2a = 0 + 5
-2a = 0 + 5

Combine like terms: 0 + 5 = 5
-2a = 5

Divide each side by '-2'.
a = -2.5

Simplifying
a = -2.5
Subproblem 2
Set the factor '(4 + -3a)' equal to zero and attempt to solve:

Simplifying
4 + -3a = 0

Solving
4 + -3a = 0

Move all terms containing a to the left, all other terms to the right.

Add '-4' to each side of the equation.
4 + -4 + -3a = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -3a = 0 + -4
-3a = 0 + -4

Combine like terms: 0 + -4 = -4
-3a = -4

Divide each side by '-3'.
a = 1.333333333

Simplifying
a = 1.333333333
Solution
a = {-2.5, 1.333333333}
