The Inequality that has the graph shown below is [tex]y \ge -\frac{1}{4}x + 1.[/tex] correct choice is [tex]y \ge -\frac{1}{4}x + 1.[/tex]
This can be seen by noting that the line is solid and shaded above the line, which indicates that all points above the line satisfy the inequality.
Graphs are often used to visually represent inequalities in mathematics. Inequalities compare the relative sizes of two expressions, and their graphs help illustrate the solutions to these inequalities on a number line or in a coordinate plane
The other inequalities in the image are not correct because:
[tex]y > -\frac{1}{4}x + 1[/tex]would have the line shaded below the line.
[tex]y < = -\frac{1}{4}x + 1[/tex] would have the line dashed, not solid.
[tex]y < -\frac{1}{4}x + 1[/tex]would have no points above the line satisfying the inequality.
Therefore, the correct inequality is [tex]y \ge -\frac{1}{4}x + 1.[/tex]

Answers
Answer:
The most common salary is $605. The salary that half the employees salaries surpass is $630. The percent of employees salary that serve because $700 is 75%. Percent of employees salaries that were less than $480 is 25%. The 9% percent of employees salaries this surpass $891 years. The total weekly salary of 104 employees is 57200.
Step-by-step explanation:
It is given that mean is $550, first quartile is $480, median is $630, third quartile is $700, mode is $605 and 91st percentile is $891.
First quartile is at 25% of the data, median is at 50% of the data, third quartile is at 75% of the data.
The mode of a set of data values is the value that occurs most often.
The most common salary is mode, therefore the most common salary is $605.
The salary that half the employees salaries surpass is $630. Because median is the half of the data.
The percent of employees salary that serve because $700 is 75%. Because $700 is third quartile.
Percent of employees salaries that were less than $480 is 25%. Because $480 is first quartile.
The percent of employees salaries this surpass $891 years is 9%. Because $891 is 91 percentile. Therefore 9% employees get more than $891.
If the company has 104 employees than the total salary of employees is
[tex]104\times 550=57200[/tex]
because means is $550, therefore the total weekly salary of 104 employees is 57200.
The most common salary is [tex]605USD[/tex].
The salary that half the employees' salaries surpass is [tex]630USD[/tex].
The percent of employees salary that serves because [tex]700USD[/tex] is [tex]75[/tex]%.

G the base of a solid is the circle x2 + y2 = 9. cross sections of the solid perpendicular to the x-axis are equilateral triangles. what is the volume, in cubic units, of the solid
Answers
Final answer:
To find the volume of the solid, we can use the formula V = A * h, where A is the area of the base and h is the perpendicular height. Given that the base is a circle and the cross sections of the solid are equilateral triangles, we can calculate the volume by integrating the expression for the area of the cross section from -3 to 3.
Explanation:
To find the volume of the solid, we can use the formula V = A * h, where A is the area of the base and h is the perpendicular height.
Given that the base is a circle with equation x^2 + y^2 = 9, we can determine the radius of the circle to be 3 units.
The cross sections of the solid perpendicular to the x-axis form equilateral triangles. The side length of an equilateral triangle is equal to the radius of the circle, which is 3 units. Since the height of each elemental cylinder is 2y, and the height of an equilateral triangle is h = √(3^2 - (3/2)^2) = √(9 - 9/4) = √(36/4 - 9/4) = √(27/4), the volume of each elemental cylinder is 4π(3^2 - x^2)^(1/2) dx = 4π(27 - 4x^2)^(1/2) dx.
To find the total volume of the solid, we integrate the expression 4π(27 - 4x^2)^(1/2)dx from x = -3 to x = 3.
∫(4π(27 - 4x^2)^(1/2)dx from -3 to 3 = 4π∫(27 - 4x^2)^(1/2)dx from -3 to 3 = 4π∫(27 - 4x^2)^(1/2)dx from -3 to 3 = 4π∫(27 - 4x^2)^(1/2)dx from -3 to 3 = 4π(3^3/3 - (-3)^3/3) = 36π units^3.

While passing a slower car on the highway, i accelerate uniformly from 12 m/s to 24 m/s in a time of 10.0s. How far do you travel during this time and what is the magnitude of your acceleration
Answers
vf-vi=at (final velocity minus initial velocity is equal to acceleration times time)
We know vf, vi, and t so we can solve for acceleration:
24-12=a10
12=10a
a=1.2
That is the acceleration, we will need to integrate with respect to time twice...
v=⌠a dt
v=at+vi , we know a=1.2m/s^2 and vi=12m/s
v=1.2t+12,
x=⌠1.2t+12 dt
x=1.2t^2/2+12t+xo, we can just let xo=0 for this problem...
x(t)=0.6t^2+12t
Now we know that this acceleration lasts for 10 seconds so the distance traveled in that time is:
x(10)=0.6(10^2)+12(10)
x(10)=60+120
x(10)=180 meters

Answers
60/24 = 2.5 degree drop per hr...so the average temp change is -2.5 degrees per hr
The average temperature change per hour is -2.5 F per hour.
What is temperature?Temperature is simply an average measure of the kinetic energy for particles of matter.
Here,
at t = 0 hour, Temp. = 46 F
at t = 24 hours, Temp. = -14 F
Now, average temp change per hour = (T₂-T₁)/(t₂-t₁)
= (-14-46)/(24-0)
= -60/24
= -2.5 F per hour
Thus, the average temperature change per hour is -2.5 F per hour.

Riverside bank offers to lend you $50,000 at a nominal rate of 6.5%, compounded monthly. the loan (principal plus interest) must be repaid at the end of the year. midwest bank also offers to lend you the $50,000, but it will charge an annual rate of 6.2%, with no interest due until the end of the year. how much higher or lower is the effective annual rate charged by midwest versus the rate charged by riverside
Answers
The effective annual rate of Midwest is 0.2% lower than the rate charged by Riverside.
Further Explanation:
Riverside Bank:
Principal = $50,000
Duration = 1 year
APR = 6.5%
The amount paid after 1 year is
A = 50000(1 + 0.065/12)¹² = $53,348.59
Midwest Bank:
Principal = $50,000
APR = 6.2%
Duration = 1 year
The amount paid after 1 year is
A = 50000*(1 + 0.062) = $53,100.00
The amount charged by Midwest is lower:
Let r = the effective annual rate of Riverside Bank.
Then
50000*(1 + r) = 53348.59
1 + r = 53348.59/50000 = 1.067
r = 0.067 = 6.7%
Effective annual rate:
The viable yearly financing cost is the loan fee that is really earned or paid on a venture, advance or other money related item because of the aftereffect of intensifying over a given timeframe. It is additionally called the powerful loan cost, the viable rate or the yearly comparable rate.
Instructions to Calculate the Effective annual Rate:
1. Determine the expressed loan fee. The expressed financing cost (additionally called yearly rate or ostensible rate) is generally found in the features of the credit or store understanding.
2. Determine the quantity of aggravating periods.
3. Apply the EAR Formula: EAR = (1+ I/n)n – 1.

Answers
f(x) = x⁵ and g(x) = 5x
are shown in the figure below.
The initial plot interval is -2 ≤ x ≤ 2.
In order to determine the points of intersection (to 1 decimal place accuracy) more graphs (shown in accompanying figures) were necessary.
The points of intersection are
x = -1.5, x = 0, and x = 1.5
Answer:
The points of intersection are x = -1.5, 0, and 1.5 (accurate to 1 decimal place)
To compare the functions f(x) = x^5 and g(x) = 5x, graph both functions and find their points of intersection.
Explanation:To compare the functions f(x) = x^5 and g(x) = 5x, we can graph both functions in several viewing rectangles. By finding the points of intersection of the graphs, we can compare their values at those points.
Start by graphing the function f(x) = x^5 using a graphing calculator or software. This will give us a curve with a steep increase as x gets larger.Next, graph the function g(x) = 5x in the same viewing rectangle as f(x). This will give us a straight line that increases more gradually as x gets larger.Identify the points of intersection between the graphs of f(x) and g(x). These are the x-values at which the two functions have the same y-value. Round these x-values to one decimal place and list them as the points of intersection.52.85 rounded to nearest tenth

How many 3 person group can be formed in a club with 8 people?
Answers
The first person in the group can be selected in any one of 8 ways.
Once selected, the second person can be selected in any one of 7 ways.
Once the first two are selected, the remaining person can be selected in any one of 6 ways.
This can be done in a total of 8 x 7 x 6 ways.
But, since the order in which the people appear in the group is not important, and since 3 people can be arranged in 3 x 2 x 1 = 6 ways, you need to divide the above number by 6 to filter out those groups with the same members (just rearranged). The answer is therefore,
(8 x 7 x 6) / (3 x 2 x 1) = 56
The number of three person group that can be formed in a club of 8 people would be = 56.
How to calculate the number of three person groups?To calculate the number of three person groups when 8 people are involved, the following steps needs to be taken as follows;
The combination formula should be used = n!/(n-r)!r!
Where:
n= 8
r= 3
Combination=8!/(8-3)!×3!
= 8×7×6×5!/5!×3!
