The error which Mason made was subtracting 5 from both sides.
The correct solution is x < 16 and it is shown on the number line below.
The best way to describe the temperature in the greenhouse before the heater stopped working is that it was at least 71 degrees.
An inequality that represent this situation is x + 21 ≥ 47 and the solution is x ≥ 26.
The inequalities that can be used to represent the situation are;
D. x - 7.35 ≥ 2.87
E. x ≥ 10.22
How to write and determine the solution to the inequalities?Based on the information provided about the math test, the following inequality must be solved by students;
x - 5 < 11
By adding 5 to both sides of the inequality, we have the following:
x - 5 + 5 < 11 + 5
x < 16
Therefore, the error which Mason made was subtracting 5 from both sides.
Since the temperature dropped 6 degrees before it was fixed and it was still at least 67 degrees when the heater started working again, we can model it as follows;
x - 4 ≥ 67
x ≥ 71
Since Ramiro has $21 and wants buy a skateboard that cost $47, the amount of money that he needs can be modeled by this inequality;
x + 21 ≥ 47
x ≥ 47 - 21
x ≥ 26
In conclusion, the inequalities that can be used to represent the total amount, x, Kendra needs for the bead are;
x - 7.35 ≥ 2.87
x ≥ 2.87 + 7.35
x ≥ 10.22

Movies generally lose 23% of its audience for each week it is in the theatre. A movie STARTED with an audience of 196 people per viewing.
a. Equation: ________________
b. Make a chart and fill in the table for the first ten weeks.
c. Graph the function. Label each axis with a title and scale
Answers
Answers:
a) The equation is y = 196(0.77)^x
b) The chart is shown below
c) The graph is shown below
================================================
Explanation:
Part (a)
One template of an exponential equation is y = ab^x
a = starting valueb = connected to the growth rate or decay rateIn this case
a = 196b = 1-0.23 = 0.77If 23% of the audience leaves, then 77% remains. This is another way to see where b = 0.77 comes from. Exponential decay will have 0 < b < 1.
Therefore, the equation is y = 196(0.77)^x
Other equations are possible.
-------------------
Part (b)
I'll be using LibreOffice spreadsheet to make the table. Any spreadsheet software will do.
Type x into cell A1
Type 0 and 1 into cells A2 and A3 in that order.
Select cells A2 and A3. Pull down the small marker at the bottom right corner. Pull this marker down to cell A12 to get values 2 through 10 (which will be in cells A4 to A12).
Now move to cell B1. Type in y = 196(0.77)^x in this cell.
In cell B2, type in "=ROUND(196*(0.77)^A2)" without quotes. As you can probably guess, the ROUND function will round to the nearest whole number. The calculation 196*(0.77)^A2 computes the result of y = 196*0.77^x when plugging x = 0 which is in cell A2.
Do not forget about the equal sign up front.
After cell B2 is filled in, hit enter. Then pull down the smaller marker at the bottom right corner to cell B12. A bunch of whole numbers should fill in cells B3 to B12
This is what you should get for your table
[tex]\begin{array}{|c|c|} \cline{1-2}\text{x} & \text{y} = 196(0.77)^{\text{x}}\\\cline{1-2}0 & 196\\\cline{1-2}1 & 151\\\cline{1-2}2 & 116\\\cline{1-2}3 & 89\\\cline{1-2}4 & 69\\\cline{1-2}5 & 53\\\cline{1-2}6 & 41\\\cline{1-2}7 & 31\\\cline{1-2}8 & 24\\\cline{1-2}9 & 19\\\cline{1-2}10 & 14\\\cline{1-2}\end{array}[/tex]
x = week number
y = viewer count (approximate)
Example calculation:
Plug in x = 5 to get y = 196*0.77^5 = 53.05297 approximately which rounds to y = 53. Therefore, we estimate there would be about 53 people in the audience for week 5.
-------------------
Part (c)
You could use a spreadsheet to make the graph, but I find GeoGebra is more friendly for graphing. But we'll be using the data we just made in the spreadsheet.
Select cells A2 through B12. This is the 11 row by 2 column block of x,y data pairs. Do not select the headers at the top.
Copy that data and paste it into GeoGebra's spreadsheet mode.
Then select that same block of data in GeoGebra. Right-click to go to "create" then to "list of points". It will do as it describes. Eleven points will show up in the graph window. Resize and adjust the window if needed.
I'm using the following window parameters
xMin = -5xMax = 20yMin = -20yMax = 220The graph is shown in the screenshot below.
Answer:
[tex]\textsf{a.} \quad \textsf{Equation:} \;\;\;y=196(0.77)^x[/tex]
b. See below.
c. See attachment.
Step-by-step explanation:
We can model the given situation using an exponential decay equation since the weekly change in audience is a constant percentage change.
Exponential decay formula[tex]\boxed{y=a(1-r)^x}[/tex]
where:
a is the initial value.r is the percentage decrease (in decimal form).x is the time period.Given the movie started with an audience of 196 people viewing, a = 196.
Given the movie loses 23% of its audience each week, r = 0.23.
As the movie loses a constant percentage of its audience each week, let x be the number of weeks.
Substitute the values of a and r into the formula and simplify:
[tex]y=196(1-0.23)^x[/tex]
[tex]y=196(0.77)^x[/tex]
Therefore, the equation that models the given scenario is:
[tex]\boxed{y=196(1-0.23)^x}[/tex]
Create a table for the first ten weeks by substituting the values of x from zero through 10 into the equation. Round each number to the nearest whole number.
[tex]\begin{array}{|c|c|}\cline{1-2}\vphantom{\dfrac12}$Weeks$\;x&$Audience$\;y\\\cline{1-2}\vphantom{\dfrac12}0&196\\\cline{1-2}\vphantom{\dfrac12}1&151\\\cline{1-2}\vphantom{\dfrac12}2&116\\\cline{1-2}\vphantom{\dfrac12}3&89\\\cline{1-2}\vphantom{\dfrac12}4&69\\\cline{1-2}\vphantom{\dfrac12}5&53\\\cline{1-2}\vphantom{\dfrac12}6&41\\\cline{1-2}\vphantom{\dfrac12}7&31\\\cline{1-2}\vphantom{\dfrac12}8&24\\\cline{1-2}\vphantom{\dfrac12}9&19\\\cline{1-2}\vphantom{\dfrac12}10&14\\\cline{1-2}\end{array}[/tex]
The graph of the function is an exponential decay curve, which starts at (0, 196) and approaches zero as x approaches infinity.
The x-axis represents the number of weeks and the y-axis represents the audience size.
Use a scale of x : y = 1 : 10.
Plot the points from the table and draw a smooth curve through them that approaches zero as x approaches infinity.

The derivative of y with respect to x is:
[tex]dy/dx = -4x / (1 - x^4)[/tex]
How to find derivative ?The chain rule and the quotient rule must be utilized in order to determine the derivative of y with respect to x.:
First, we can rewrite y as follows:
[tex]y = ln[(1 - x^2)/(1 + x^2)][/tex]
Let's define two functions:
[tex]u = 1 - x^2[/tex]
[tex]v = 1 + x^2[/tex]
Then, y can be rewritten in terms of u and v as:
y = ln(u/v)
Now, we can use the chain rule to find the derivative of y with respect to u and v, respectively:
[tex]dy/du = 1/u\\dy/dv = -1/v[/tex]
Using the quotient rule, we can find the derivative of y with respect to x:
[tex]dy/dx = (dy/du) * (du/dx) + (dy/dv) * (dv/dx)[/tex]
[tex]du/dx = -2x\\dv/dx = 2x[/tex]
Substituting in the values we get:
[tex]dy/dx = (dy/du) * (du/dx) + (dy/dv) * (dv/dx)\\= (1/u) * (-2x) + (-1/v) * (2x)\\= -2x/(1 - x^2) - 2x/(1 + x^2)\\= -4x / (1 - x^4)[/tex]
Therefore, the derivative of y with respect to x is:
[tex]dy/dx = -4x / (1 - x^4)[/tex]

How do I find the squareroot?
Answers
Answer:
Step-by-step explanation:
Factoring a square root means that you are finding the closest numbers that multiply together. The easiest square roots are ones that factor directly into squares, such as √100, but more complicated ones involve several square roots, such as √225. Here are the steps to finding the square root using factoring:
1. Find the factors. Factors are the numbers you multiply to find the total under the square root symbol. For √100, the factors would be √(10 x 10). The factors of √225 would be √(25 x 9).
2. Separate the factors into their own square roots. Because both factors of √100 are 10, the square root of 100 is 10. For √225, you would separate the factors under their own square root signs, so the formula would be √25 x √9.
3. Solve for the individual squares. Next, you would find the squares of each of the individual factors. √25 = 5 and √9 = 3. The remaining formula will look like 5 x 3.
4. Finish solving the equation. Now that you know what the simplified squares are, you will find that 5 x 3 = 15. So, √225 = 15.

The Hartford offered an annuity that pays 5.5% compounded monthly.
What equal monthly deposit should be made into this annuity in order
to have $100000 in 10 years?
Answers
If an annuity pays 5.5% compounded monthly, then the "equal-monthly-deposit" to have $100000 in 10 years is $627.
In order to calculate the "monthly-deposit" needed to accumulate $100,000 in 10 years at 5.5% compounded monthly, we use the formula for the future value of an annuity:
Which is : FV = P × [(1 + r)ⁿ - 1]/r,
where:
FV is "future-value" = $100000,
P = monthly deposit
r = monthly interest rate (5.5%/12 = 0.00458)
n = number of months (10 years × 12 months per year = 120 months)
Substituting the values,
We get,
⇒ 100000 = P × [(1 + 0.00458)¹²⁰ - 1]/0.00458,
⇒ P = 100000 × 0.00458 / [(1 + 0.00458)¹²⁰ - 1],
⇒ P ≈ $627,
Therefore, an equal monthly deposit is approximately $627.

what is the best measure of sensors to use in the set of data below 12, 8, 15, 45, 7, 13 mean, median, mean or median, mode?
Answers
Answer:
The best measure of central tendency to use in a set of data depends on the characteristics of the data and the specific objective of the analysis. Let's examine the given data set: 12, 8, 15, 45, 7, 13.
Mean: The mean, also known as the average, is calculated by summing up all the values in the data set and dividing by the total number of values. The mean is sensitive to extreme values and can be influenced by outliers. In this case, the mean is calculated as (12 + 8 + 15 + 45 + 7 + 13) / 6 = 100 / 6 ≈ 16.67.
Median: The median is the middle value in a data set when the values are arranged in ascending or descending order. The median is not affected by extreme values and is a good measure to use when there are outliers or when the data is not symmetrically distributed. In this case, when the data set is arranged in ascending order, the median is 13, as it is the middle value.
Mode: The mode is the value that appears most frequently in a data set. It is a useful measure when we want to identify the most common value in the data set. In this case, the mode is not applicable as there are no repeated values in the data set.
Based on the characteristics of the given data set, the median is a good measure to use as it is not affected by extreme values and provides a central value that represents the middle of the data set. The mean may be influenced by the outlier value of 45, and the mode is not applicable in this case. So, the best measure of central tendency to use in this data set would be the median.

Answers
The equation of the line that passes through the point (-1, 1) and is parallel to a line that passes through (3, 6) and (1, -2) is: [tex]$y = 4x + 5$[/tex].
What is slope?The slope of a line is a measure of its steepness, and is calculated as the change in the y-coordinate divided by the change in the x-coordinate.
In this case, the line passing through the points (3, 6) and (1, -2) has a slope of [tex]$\frac{6 - (-2)}{3 - 1} = \frac{8}{2} = 4$[/tex].
Therefore, the line that passes through the point (-1, 1) and is parallel to the given line has the same slope of 4.
To find the equation of the line passing through (-1, 1) and having a slope of 4, we need to use the point-slope formula.
The point-slope formula is given by: [tex]$y - y_1 = m(x - x_1)$[/tex] where [tex]$(x_1, y_1)$[/tex] is a point on the line, and m is the slope of the line. In this case, [tex]$(x_1, y_1)$[/tex] is (-1, 1) and m is 4, so the equation of the line is:
[tex]$y - 1 = 4(x - (-1))$[/tex]
[tex]$y - 1 = 4x + 4$[/tex]
[tex]$y = 4x + 5$[/tex]
Therefore, the equation of the line that passes through the point (-1, 1) and is parallel to a line that passes through (3, 6) and (1, -2) is: [tex]$y = 4x + 5$[/tex].

Pounds of whole apples needed = 18 lb / 0.78Pounds of whole apples needed = 23.077 lb (rounded to three decimal places)
Therefore, you would need approximately 23.077 pounds of whole apples to make 18 pounds of peeled and cored apples with a 78% yield percentage.
find the circumference of a circle circumscribed about a right triangle with legs 5 centimeters and 3 centimeters
Answers
Answer:
Therefore, the circumference of the circle circumscribed about the right triangle with legs 5 cm and 3 cm is approximately 18.85 cm (rounded to two decimal places).
Step-by-step explanation:
To find the circumference of a circle circumscribed about a right triangle with legs 5 cm and 3 cm, we can use the Pythagorean theorem to find the length of the hypotenuse, which is also the diameter of the circle.
Using the Pythagorean theorem, we have:
c^2 = 5^2 + 3^2
c^2 = 25 + 9
c^2 = 34
c = sqrt(34)
So the diameter of the circle is sqrt(34) cm, and the radius is half of the diameter, or sqrt(34)/2 cm.
The circumference of a circle is given by the formula:
C = 2 * pi * r
where pi is approximately 3.14 and r is the radius of the circle.
Substituting the value of the radius, we get:
C = 2 * 3.14 * sqrt(34)/2
C = 3.14 * sqrt(34)
Therefore, the circumference of the circle circumscribed about the right triangle with legs 5 cm and 3 cm is approximately 18.85 cm (rounded to two decimal places).
3x+2=8 what is the value of x
Answers
Answer:
x = 2
Step-by-step explanation:
3x + 2 = 8
Subtracting both sides by 2 we get,
=> 3x + 2 - 2= 8 - 2
=> 3x = 6
=> x = 6/3
=> x = 2
3x + 2 - 2 = 8 - 2
3x = 6
3x/3 = 6/3
x = 2

The claim is that for a smartphone carrier's data speeds at airports, the mean is 18.00 Mbps. The sample size is n= 14 and the test statistic is t= -2.645 .
whats the P-value?
Answers
According to given information the P-value is approximately 0.016.
What is P-value?In statistical hypothesis testing, the p-value is the probability of obtaining a test statistic as extreme as or more extreme than the observed results, under the assumption that the null hypothesis is true.
According to given information:To find the P-value for this hypothesis test, we need to use a t-distribution with degrees of freedom equal to n-1 = 14-1 = 13. Since the test statistic is t = -2.645, we need to find the area under the t-distribution curve to the left of t.
Using a t-table or calculator, we can find that the area to the left of t = -2.645 with 13 degrees of freedom is approximately 0.008. This is the probability of observing a t-value less extreme than -2.645, assuming the null hypothesis is true.
Since this is a two-tailed test (we are testing whether the true mean is less than or greater than 18.00 Mbps), we need to double the one-tailed P-value to get the two-tailed P-value. Therefore, the P-value is approximately 0.016 (i.e., 2 x 0.008).
So, the P-value is approximately 0.016.

Determine the function is positive, negative, increasing, or decreasing. Then describe the end behavior of the function.
Answers
The function is positive and increasing.
Given is an exponential function y = √4x,
So, since all the value of the function will be above x-axis therefore, the function is positive.
Now,
Differentiating the function,
y' = d(√4x)/dx
y' = 1/2 × [tex]4x^{-1/2[/tex]
y' = 1/2√4x
y' = 1/4√x
Since, y' > 0, therefore, the function is increasing.
Now,
For functions with exponential growth, we have the following end behavior.
The end behavior on the left (as x → -∞), it has a horizontal asymptote at y = 0,
The end behavior on the right (as x → ∞), y→ ∞.

The index of refraction of the second material is 1.27.
We are given that;
Angle= 59°
Randomized Variables 1 = 1.47θ1 = 59°θ2 = 69°
Now,
To find n2, we can rearrange Snell’s law as:
n2 = n1 sin θ1 / sin θ2
Plugging in the given values, we get:
n2 = 1.47 sin 59° / sin 69°
n2 = 1.47 (0.857) / (0.934)

What are similar triangles?Two or more triangles will always be referred to as similar if on comparing their corresponding properties, some common relations holds. Some of the relations are relations between their length of sides, relations among their internal angles etc.
To determine the height of the building, we have;
height of pole = 7 ft
total length of the building's shadow = 167 ft
the length of the shadow of the pole = 4.75 ft
Let the height of the building be represented by h. On comparison, we have;
4.75/ 167 = 7/h
4.75h = 167 x 7
= 1169
h = 1169/ 4.75
= 246.11

what is the inverse of f(x)=(4x-9)^1/2
Answers
The inverse of f(x) = [tex](4x-9)^{1/2[/tex] when the variables of x and y are switched is [tex]F(x)^{-1}[/tex] = [tex]\frac{x^{2}+9 }{4}[/tex]
What is an Inverse of a Function?Inverse of a function is a function which can be reversed into another function. It is also a function that undoes the action of the another function.
How to determine this
When f(x) = (4x-9)^1/2
To determine the inverse, [tex]f(x)^{-1}[/tex]= y
y = (4x-9)^1/2
y = [tex]\sqrt{4x-9}[/tex]
By squaring both sides
y^2 = 4x - 9
By swapping the variables
x^2 = 4y - 9
Subtracting 9 from both sides
x^2 +9 = 4y
divide through by 4
[tex]\frac{x^{2}+9 }{4}[/tex] = 4y/4
y = [tex]\frac{x^{2}+9 }{4}[/tex]
Therefore [tex]F(x)^{-1}[/tex] = [tex]\frac{x^{2}+9 }{4}[/tex]
