Select the graph of y=cot x.
Answers
Because of the vertical asymptote and the change in concavity, we conclude that the correct option is B.
Which is the graph of cotangent of x?Remember that cot(x) = 1/tan(x).
Then we can rewrite:
cot(x) = cos(x)/sin(x).
We know that for x = 0, we have:
cot(0) = cos(0)/sin(0) = 1/0
Then we have a vertical asymptote that tends to ± infinity.
The only graph that meets this condition is the second and the third one, and by the curvature (we need to have a change of concavity/convexity) in the tangent function.
From that, we conclude that the correct option is B.

Find the mean of the following data : Marks 0-10 No. of students 5 0-20 10 0-30 14 0-40 17 Ans/22 0-50 20
Answers
Mean of the data as per the increasing intervals data is 17.80.
Define mean?The mean in statistics is calculated by multiplying all the values in a set of data by the total number of values for a given set of observations. To put it another way, all that is necessary to determine the mean of a set of data is to sum up all the values and divide the total by the number of values.
Now in the given table,
The midpoints of the intervals are as follows:
0+10/2 = 5
0+20/2 = 10
0+30 /2 = 15
0+40/2 = 20
0+50/2 = 25.
Now total students × interval midpoints are as follows:
5×5=25
10×10=100
15×14=210
20×17=340
25×20=500
Now, total no of students is = 5+10+14+17+20 = 66
So, mean of the data =
(25+100+210+340+500)/66
= 17.80
Therefore, mean of the data is 17.80.

an inscribed sphere. Round to the nearest tenth.
Answers
The volume inside the cube but outside of an inscribed sphere is 231.6 cubic inches
Finding the volume inside the cube but outside of an inscribed sphere.From the question, we have the following parameters that can be used in our computation:
Cube volume = 486
This means that the side length of the cube is
l³ = 486
So, we have
l = 7.86
This represents the diameter of the sphere
So, the sphere volume is
V = 4/3πr³
So, we have
V = 4/3 * 22/7 * (7.86/2)³
Evaluate
V = 254.36
So, the required volume is
Volume = 486 - 254.36
Evaluate
Volume = 231.64
Approximate
Volume = 231.6
Hence, the volume inside the cube but outside of an inscribed sphere is 231.6 cubic inches

The area of a rectangle is 80 square units. A side of the rectangle, representing the
length, is 4 units long. Which could be the vertices of aside of the rectangle that
represents the width?
Answers
Answer:
So the width of the rectangle is 20 units.
Step-by-step explanation:
Since the area of the rectangle is 80 square units and the length of one side is 4 units, we can use the formula for the area of a rectangle (A = lw) to find the width of the rectangle. We can set up the equation like this:
A = lw
80 = 4w
w = 20
So the width of the rectangle is 20 units. This means that the vertices of one of the sides of the rectangle that represents the width could be (0,0), (0,20), (20,0), and (20,20). These coordinates assume that the lower left corner of the rectangle is at the origin (0,0). If the rectangle is not at the origin, the coordinates of the vertices would be different. For example, if the lower left corner of the rectangle was at (-5,5), the coordinates of the vertices would be (-5,5), (-5,25), (15,5), and (15,25).
If a loading ramp is placed next to a truck, at a height of 8
feet, and the inclined portion of the ramp is 17 feet long, what angle (in degrees) does the ramp make with the ground?
Round your answer to one-tenth of a degree.
Answers
The angle that the ramp makes with the ground is approximately 28.07 degrees.
What are trig ratios?If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.
Here,
The sin of the angle θ is the ratio of the opposite side (height of the ramp) to the adjacent side (length of the inclined portion of the ramp):
Sin(θ) = 8/17
We can use a calculator to find the inverse sin of this ratio to get the angle θ:
θ = sin⁻¹(8/17)
θ ≈ 28.07 degrees
Therefore, the angle that the ramp makes with the ground is approximately 28.07 degrees.

Marc and Michelle are married and earned salaries this year of $64,000 and $12,000, respectively. In addition to their salaries, they received interest of $350 from municipal bonds and $500 from corporate bonds. Marc contributed $2,500 to an individual retirement account, and Marc paid alimony to a prior spouse in the amount of $1,500. Marc and Michelle have a 10-year-old son, Matthew, who lived with them throughout the entire year. Thus, Marc and Michelle are allowed to claim a $2,000 child tax credit for Matthew. Marc and Michelle paid $6,000 of expenditures that qualify as itemized deductions and they had a total of $3,500 in federal income taxes withheld from their paychecks during the course of the year. What is Marc and Michelle's adjusted gross income?
Answers
Answer:
The total amount of deductions Marc and Michelle are going to get is $24750.
The taxable income of Marc and Michelle is $47750.
Further Explanation:
Income Tax: It is the additional charge on an individual’s income which he/she needs to pay to the government. The taxable income is calculated by adding all the incomes and deducting all the deductions which an individual can claim on his/her income.
Compute the total amount of deductions available for Marc and Michelle:
Total Deduction Available
= Higher of Standard Deduction for MJF and Itemized Deduction + Personal and Dependency Exemptions
= Higher of $12600 and $6000 + $12150 ($4050×3)
= $12600 + $12150
=$24750.
Therefore, the total deductions available to Marc and Michelle are $24750.
Gross Income of Marc and Michelle
= Salary of Marc + Salary of Michelle + Interest Earned on Corporate Bonds
= $64000 + $12000 + 500
= $76500.
Total Taxable Income of Marc and Michelle
= Gross Income – Qualified Moving Expenses – Alimony Paid – Total Deductions
= $76500 - $2500 - $1500 - $$24750
= $47750.
Therefore, the total taxable income of Marc and Michelle is $47750.

Part 2: 12% annual interest on 106,750 for 20 days.
If it helps, it's a 5 year note. Assuming 365 days in a year.
Answers
The interest for Part 1 is approximately $385.10.
The interest for Part 2 is approximately $709.31.
To calculate the interest for Part 1 and Part 2The formula is as follows:
Interest is calculated as follows: Principal * Rate * Time
Where
Principal represents the starting sumThe interest rate is rateTime measures length in years.Part 1:
$132,000 is the principal.
(Decimal) Rate = 12% = 0.12
Time = 8 days/365 days.
How much interest is there in Part 1?
Interest is calculated as follows : $132,000 * 0.12 * (8/365) = $385.10
Therefore, the interest for Part 1 is approximately $385.10.
Part 2:
$106,750 as the principal
(Decimal) Rate = 12% = 0.12
Time = 20 days / 365 days.
How much interest will there be in Part 2
Interest is calculated as follows : $106,750 * 0.12 * (20/365) = $709.31
Therefore, the interest for Part 2 is approximately $709.31.

Generally speaking, there are one (1) kilometer in one thousand (1,000) meters. This ultimately implies that, a proportion or ratio for the conversion of kilometer to meters would be written as follows;
Conversion:
1 kilometer = 1,000 meters
2 kilometer = 2,000 meters
3 kilometer = 3,000 meters
4 kilometer = 4,000 meters
5 kilometer = 5,000 meters

Answers
If only 2,836 students were admitted into the Ateneo among 27,813 students, who took the ACET this year, the Ateneo’s acceptance rate is b. 10.2%.
How the rate is determined:The rate is the ratio of one value, expression, measurement, or quantity compared to another.
The rate represents the quotient of the numerator and the denominator.
The rate is expressed as a percentage by multiplication with 100.
The number of students who took the ACET this year = 27,813
The number of students who were admitted into the Ateneo = 2,836
The percentage or rate admitted = 10.19667% (2,836 ÷ 27,813 × 100)
= 10.2%
Thus, we can conclude that the acceptance rate or percentage is Option B.

Answers
Let's draw the circle and the lines to see more clear:
The AB and CD are diameters of the circle, so the intersection point K is the center of the circle.
We know the angle BKD=100°, but the angle AKC=BKD because they are opposite angles.
So the measure of arc AC is:
\(\begin{gathered} \text{arc AC=}\angle AKC\cdot r \\ \text{where the r is the radius of the circle} \end{gathered}\)You should note the angle AKC in the above equation must be in radians. To convert degrees to radians use the following equation:
\(\angle AKC(radians)=\frac{\pi}{180}\angle AKC(degrees)\)So,
\(\text{arc AC=}\frac{\pi}{180}\cdot100\cdot r=\frac{5}{9}\pi\cdot r\)
