Consider a buffer made by adding 132.8 g of nac₇h₅o₂ to 300.0 ml of 2.31 m hc₇h₅o₂ (ka = 6.3 x 10⁻⁵) what is the ph of the buffer after 0.750 mol of h⁺ have been added?
The ph of the buffer solution given after 0.750 mol of H⁺ have been added is; 4.34
What is the PH of the Buffer?pKa = -log(Ka) = 4.20
[A⁻] = [NaC₇H₅O₂]
[HA] = [HC₇H₅O₂]
Concentration of NaC₇H₅O₂ in the preferred buffer solution is;
[132.8g/(144.11 g/mol * 300 mol)] * 1000 mL/1 L = 3.07 M
Formula for the PH here is;
pH = pKa + log [A⁻/HA]
Thus;
pH = -log(6.3 x 10⁻⁵) + log [3.07/2.31]
pH = 4.34

According to rational-emotive behavior therapists, the source of much unhappiness is the individual’s
Rational-emotive behavior therapists propose to review the thought patterns associated with emotional discomfort where the source of much unhappiness is the individual's system of inappropriate beliefs.
What is the rational-emotive-behavioral approach?It is an approach that considers that behavioral and emotional problems could have their genesis from three sources: thought, emotional and behavioral.
This affirmed that people are largely responsible for their disturbed feelings, therefore, those same people have all the resources to be able to modify their thoughts and bring lasting and stable states to their lives.
Therefore, we can conclude that rational-emotive behavior therapists propose to review the thought patterns associated with emotional discomfort where the source of much unhappiness is the individual's system of inappropriate beliefs.

College algebra and trigonometry 5th edition answers
The algebra shows that the line ax + y + c is perpendicular to the line x - by = d, then a/b = 1.
How to solve the algebra?Firstly, write the equations of line in the slope intercept form. The equation ax + y = can be rewritten as y = ax + c. The slope of the line is m = a.
The equation x - by = d can be written as y = 1/bx - d/b. Therefore, the second slope will be 1/b.
Then, we multiply the slopes. Therefore, (-a)(1/b) = -1.
In conclusion, a/b = 1.

Of the 10,000 clocks from which the sample was chosen, about how many clocks are probably not defective?
The number of clocks that are not defective is an illustration of proportions
Of the 10000 clocks, 9250 are probably not defective
How to determine the number of clocks that are not defective?From the complete question, we have the following parameter:
15 out of 200 clocks are defective
The above means that the number of clocks that are not defective is:
Not defective = 200 - 15
Not defective = 185
Express as percentage
Not defective = 185/200
Not defective = 92.5%
In 10,000 the number of clocks that are not defective would be:
Not defective = 92.5% * 10000
Not defective = 9250
Hence, 9250 of the 10000 clocks are probably not defective

Among all pairs of numbers whose difference is 14 find a pair whose product is as small as possible
The pair two numbers whose difference is 14 and the product is as small as possible (i.e. -49) are (-7,7)
What are word problems?In mathematical concepts, word problems involve a crucial understanding of the problem and knowing which mathematical method and arithmetic operations are best suited to solving the problem.
If we assume that the smaller number should be = a and the larger number = a + 14.
Thus, their product (X) can be expressed as:
= a(a+14)
= a² + 14a
The smallest possible value implies the minimum value, i.e.
[tex]\mathbf{\dfrac{dX}{da} = 2a + 14}[/tex]
Thus,
2a + 14 = 0
a = - 14/2
a = -7
Therefore, we can conclude that the pair of two numbers whose difference is 14 and the product is as small as possible (i.e. -49) is (-7,7).

Suppose that the rabbit population on mr. jenkins' farm follows the formula
Jenkins' farm tracks the procedure p(t)=3000tt+1. where t≥0 is the period (in months) since the start of the year.
As time (t) increases, the rabbit population (p(t)) will also increase, but it will approach a maximum value without ever actually reaching it, resulting in continuous growth that slows down over time.
We have,
Given formula: p(t) = 300t / (t + 1)
As time (t) increases, the denominator (t + 1) also increases.
The rabbit population (p(t)) is calculated by dividing 300t by (t + 1).
Now, let's examine the behaviour as t becomes larger:
When t is very small (close to 0), the population p(t) is also small, since the denominator (t + 1) is close to 1.
As t increases, the denominator (t + 1) grows, causing the value of p(t) to increase.
However, the rate of increase slows down as t gets larger.
This is because the denominator grows faster than the numerator (300t).
Eventually, as t becomes very large, the value of p(t) approaches but never quite reaches a maximum value.
This behaviour is characteristic of a rational function where the numerator's growth is outpaced by the denominator's growth, resulting in an asymptotic approach to a certain value.
Thus,
As time (t) increases, the rabbit population (p(t)) will also increase, but it will approach a maximum value without ever actually reaching it, resulting in continuous growth that slows down over time.

6-4 practice elimination using multiplication answers
Multiplication as a method of elimination is used to eliminate an unknown in a system of equations by multiplying one of the equations by a constant.
What is the Gauss method?It is the method of eliminating unknowns that transforms a linear system into a triangular system, so that it is possible to solve the problem with retroactive resolution. Like for example:
2x+3y=143x-4y=4A) The first step is to solve equation 2 to find the variable x.
3x=4y+4x=4y/3+4/3B) The second step is to include the variable x found in equation 1.
2x(4y/3+4/3)+3y=14
17y/3=34/3
17y=34
C) The third step is to solve equation 1 to find the variable y.
17y=34y=2D)Now that we've found the value of y, we can solve equation 1 to find the value of x.
x=4/3x(2)+4/3=4Therefore, if the value of x is 4 and the value of y is 2, the solution of this exercise, using the Gauss method is (4;2).
