Mariya is solving the quadratic equation by completing the square.
4x2 – 20x + 3 = 0
4x2 – 20x = –3
A(x2 – 5x) = –3
What is the value of A?
Answer:
The value of A is 4.
Step-by-step explanation:
Consider the provided quadratic equation.
[tex]4x^2-20x+3=0[/tex]
Subtract 3 from both sides.
[tex]4x^2-20x+3-3=-3[/tex]
[tex]4x^2-20x=-3[/tex]
Now take 4 common from the left side of the above equation.
[tex]4(x^2-5x)=-3[/tex]
Compare the above equation with [tex]A(x^2 - 5x) = -3[/tex]
By the comparison it is clear the value of A is 4.
Hence, the value of A is 4.

Let gg be an exponential function that is changing at a rate proportional to itself, with constant of proportionality 0.60.6. (a) what's the growth factor of gg? .6 . (b) the function gg exhibits
The growth factor of g is given by [tex]A = e^{0.6t}.[/tex]
The function exhibits exponential growth.
We have,
(a)
Let's denote the growth factor as A(t), where t is the independent variable representing time.
The rate of change of g at any time t is proportional to g itself, with a constant of proportionality of 0.6.
This can be expressed as:
dA/dt = 0.6A
This is a separable differential equation, which we can solve by separating the variables and integrating them:
1/A dA = 0.6 dt
Integrating both sides,
ln|A| = 0.6t + C
Here, C is the constant of integration.
Exponentiating both sides:
[tex]|A| = e^{0.6t + C}[/tex]
Since the growth factor A is always positive, we can drop the absolute value:
[tex]A = e^{0.6t + C}[/tex]
We can do this by considering the initial condition.
Let's assume that at t = 0, the growth factor A is 1 (no growth). Substituting these values into the equation:
[tex]1 = e^{0.6(0) + C}\\1 = e^C[/tex]
Taking the natural logarithm of both sides:
[tex]ln(1) = ln{e^C}[/tex]
0 = C
So,
[tex]A = e^{0.6t}[/tex]
(b)
The function g exhibits exponential growth, as the value of g increases exponentially with time.
Thus,
The growth factor of g is given by [tex]A = e^{0.6t}.[/tex]
The function exhibits exponential growth.

What is Fourteen less than five times a number is three times the number and what is Twelve more than seven times a number equals the number less six?
The solution to the first algebraic equation is x = 7, and the solution to the second equation is x = -3. Both problems involve setting up and solving algebraic equations to find the value of the unknown number.
To solve the problems stated, we need to set up algebraic equations and solve for the unknown number x.
For the first one:
Fourteen less than five times a number is three times the number: 5x - 14 = 3x.
After simplifying, we get 2x = 14.
Divide both sides by 2 to find x = 7.
For the second one:
Twelve more than seven times a number equals the number less six: 7x + 12 = x - 6.
Rearrange to find 6x = -18.
Divide both sides by 6 to find x = -3.
We have found that the unknown number in the first equation is 7 and in the second equation, it is -3.

Factor this expression completely and then place the factors in the proper location on the grid. Note: Place factors alphabetically in the grid! mr + ns - nr - ms
Answer:
(m-n)(r-s)
Step-by-step explanation:
We will factor this by grouping. First we rearrange the terms so the m's are together and the n's are together:
mr-ms+ns-nr
Next we group the first two and the last two:
(mr-ms)+(ns-nr)
The GCF of the first group is m; factor this out:
m(r-s)+(ns-nr)
The GCF of the second group is n; factor this out:
m(r-s)+n(s-r)
We want to have the same thing in both sets of parentheses; to do this, we will multiply the second factor by -1:
m(r-s)+-n(r-s)
Factoring out the term now in common, r-s, we have
(r-s)(m-n) = (m-n)(r-s)

during the 2009-2010 basketball season, the number of points scored in each game by the boston celtics was approximately normally distributed with a mean of 99.2 points and a standard deviation of 10.5 pthe mean number of points scored by los angeles lakers was 101.7. in what proportion of their games did the celtics score more than the lakers' mean score?
To solve this problem, we use the z statistic. The z formula is:
z = (x – u) / s
where x is lakers score = 101.7, u is Celtics score = 99.2, s is standard dev = 10.5
z = (101.7 – 99.2) / 10.5 = 0.24
using the normal distribution table at z = 0.24, the P value is:
P (z = 0.24) = 0.5984 = 59.84%
To find the proportion of games in which the Boston Celtics scored more than the Los Angeles Lakers' mean score, we need to standardize the Lakers' mean score, find the z-score, and then find the proportion from the standard normal distribution table.
Explanation:To find the proportion of games in which the Boston Celtics scored more than the Los Angeles Lakers' mean score, we need to find the area under the normal distribution curve to the right of the Lakers' mean. First, we need to standardize the Lakers' mean score by finding the z-score using the formula:
z = (x - μ) / σ
where x is the mean score, μ is the mean of the Celtics' scores, and σ is the standard deviation of the Celtics' scores. Substituting the given values, we have:
z = (101.7 - 99.2) / 10.5 = 0.2381
Next, we find the proportion of scores greater than the Lakers' mean in the standard normal distribution table or using a calculator. Looking up the z-score of 0.2381 in the table, we find the proportion to be approximately 0.4069, or 40.69%.

The fifth period Coordinate Algebra class received their quiz grades back from Mr. Smith today. The students were offered a chance for five quiz points if they constructed a box and whisker plot using the 20 quiz scores. As Mr. Smith's teaching assistant, you are asked to create a solution key for the box and whisker plot. Mr. Smith asked you to report back to him tomorrow morning with the Q1, Q3, and IQR.Use the set of student quiz scores to complete your calculations. Complete your work in the space provided or upload a file that can display math symbols if your work requires it.Turn in the Q1, Q3, and IQR and all of the necessary steps that you took to make your calculations. Fifth Period Quiz Grades: 100, 96, 58, 95, 60, 95, 69, 88, 71, 95, 85, 93, 91, 78, 78, 85, 86, 98, 87, 100
"To create a box and whisker plot and calculate the Q1, Q3, and IQR for the given set of quiz grades, we must first organize the data in ascending order:
58, 60, 69, 71, 78, 78, 85, 85, 86, 87, 88, 91, 93, 95, 95, 95, 96, 98, 100, 100
Next, we find the median (Q2), which is the middle value in the ordered list. Since there are 20 scores, the median will be the average of the 10th and 11th scores:
Q2 = (87 + 88) / 2 = 175 / 2 = 87.5
Now, we need to find the first quartile (Q1), which is the median of the first half of the data (excluding the median if the number of data points is odd). Since we have an even number of scores, we take the first 10 scores and find their median:
Q1 = (71 + 78) / 2 = 149 / 2 = 74.5
For the third quartile (Q3), we take the median of the second half of the data (excluding the median if the number of data points is odd). Again, we have an even number of scores, so we take the second set of 10 scores and find their median:
Q3 = (95 + 96) / 2 = 191 / 2 = 95.5
Finally, the interquartile range (IQR) is calculated by subtracting Q1 from Q3:
IQR = Q3 - Q1 = 95.5 - 74.5 = 21
Therefore, the Q1, Q3, and IQR for the fifth period Coordinate Algebra class quiz grades are:
Q1 = 74.5
Q3 = 95.5
IQR = 21
These values are essential for constructing the box and whisker plot and for understanding the spread of the middle 50% of the quiz scores."
