Given a function value of an acute angle, find the other five trigonometric function values
The other five trigonometric function values are cos(∅) = 11/61, tan(∅) = 60/11, sec(∅) = 61/11, csc(∅) = 61/60 and cot(∅) = 11/60
How to determine the other five trigonometric function valuesFrom the question, we have the following parameters that can be used in our computation:
sin(∅) = 60/61
The cosine of the angle can be calculated using
sin²(∅) + cos²(∅) = 1
Substitute the known values in the above equation, so, we have the following representation
(60/61)² + cos²(∅) = 1
This gives
cos²(∅) = 1 - (60/61)²
Evaluate the like terms
cos²(∅) = 121/3721
Take the square root of both sides
cos(∅) = 11/61
The tangent of the angle can be calculated using
tan(∅) = sin(∅)/cos(∅)
Substitute the known values in the above equation, so, we have the following representation
tan(∅) = (60/61)/(11/61)
Evaluate
tan(∅) = 60/11
The other ratios of the angle are calculated as follows
sec(∅) = 1/cos(∅) = 61/11
csc(∅) = 1/sin(∅) = 61/60
cot(∅) = 1/tan(∅) = 11/60

Find the measure of each numbered angle.
m∠1=_____ and m∠2=_____
Answer:
m∠1 = m∠2 = 17°
Step-by-step explanation:
You want to know the measures of the base angles of an isosceles triangle with an a.pex angle of 146°.
Angle sum theoremThe sum of angles in a triangle is 180°. We can use x to represent the measures of each of the two congruent base angles of the isosceles triangle:
x + 146° +x = 180°
2x = 34° . . . . . . subtract 146°
x = 17° . . . . . . . divide by 2
The measures of the angles are ...
m∠1 = m∠2 = 17°

1. In 60 weeks, both Zac and Jon will earn the same amount, equating to their different earnings.
2. The student's claim that the solution to the equation 200 + 20w = -100 + 25w is w = 50 is false as the solution shows that w = 60.
3. The two correct justifications for the given steps used in solving w are:
Step 1: Combining like termsStep 3: Division Property of Equality.How the equations are determined?The fixed earnings of Zac = $200
Zac's earnings per week = $20
The total earnings of Zac in w weeks = 200 + 20w
Jon's fixed debt so far = $100
Jon's earnings per week = $25
The total earnings of Jon in w weeks = -100 + 25w
To determine the weeks when the total earnings of Zac and Jon will be equal, we can equate the two expressions above as follows and solve for w:
200 + 20w = -100 + 25w
20w - 25w = -300
-5w = - 300
w = -300/-5
w = 60

The perimeter of the triangle BAG is 43. AG= 16, AB=x+4, and BG= 2x+2. What is the value of x?
Answer:
x=7
isosceles triangle
Step-by-step explanation:
To find the perimeter we just add all the sides so we do that for this too
(X+4)+(2x+2)+(16)
And we set it equal to 43 since that is perimeter
(X+4)+(2x+2)+(16)=43
Combine like terms
3x+22=43
-22. -22
3x=21
/3. /3
x=7
And if we fill in the x we find BG and AG are equal so this is an Isosceles triangle
Hopes this helps
Answer:
x = 7
Isosceles triangle
Step-by-step explanation:
The perimeter of a two-dimensional shape is the distance all the way around the outside.
Given values of triangle BAG:
Perimeter = 43AG = 16AB = x + 4BG = 2x + 2Therefore:
⇒ AG + AB + BG = perimeter
⇒ 16 + x + 4 + 2x + 2 = 43
⇒ x + 2x + 16 + 4 + 2 = 43
⇒ 3x + 22 = 43
⇒ 3x + 22 - 22 = 43 - 22
⇒ 3x = 21
⇒ 3x ÷ 3 = 21 ÷ 3
⇒ x = 7
Substitute the found value of x into the expressions for AB and BG to find their lengths:
⇒ AB = x + 4
⇒ AB = 7 + 4
⇒ AB = 11
⇒ BG = 2x + 2
⇒ BG = 2(7) + 2
⇒ BG = 14 + 2
⇒ BG = 16
As sides BG and AG are both 16 units in length, the triangle is an isosceles triangle (as it has two sides of equal length).
4. The number of minutes a person uses each month often varies. Suppose that a Verizon customer uses the total number of minutes shown below.

Main Body;
This consumer used less than 450 minutes a month every month except June and December. In June, they used 178 extra minutes and in December they used 189 extra minutes. In total, they used 367
extra minutes throughout the year. The basic fee for the 450 Plan is $39.99 per month so their annual cost is
annual cost = monthly fee* months + cost per minutes* extra minutes
=39.99 *12 +0.45* 367
=479.88+ 165.15
=645.03
Annual Cost Monthly fee months cost per minute extra minutes
The annual cost for the 450 Plan is $645.03.
The 900 Plan costs $59.99 per month for all 12 months for a total cost of $719.88. Even though the consumer had to pay extra during June and December, the 450 Plan was still less expensive than the 900 Plan.

Cost function is fixed cost added with number of hours times the variable cost.
What is cost ?
The two primary categories of costs that organizations face are fixed and variable costs. While variable costs fluctuate with output, fixed costs do not.
Sometimes, fixed costs are referred to as overhead costs. They are incurred regardless of whether a company produces 100 or 1,000 widgets.
Given that charge for a service call is $80.00 and $30.00 for each hour of work. So fixed cost is 80 and variable cost is 30.
Cost function is fixed cost added with number of hours times the variable cost.

proportion to within plus or minus 2% and be 95% sure the estimate is correct? Do
NOT take nonresponse into account. Remember, this is a sample size estimate, which
means you should round UP for your final answer.
To estimate the population proportion to within plus or minus 2% with 95% confidence, a sample size of at least 804 is needed.
How do we get the sample size for estimating a population proportion?This can be calculated using the formula for determining sample size for estimating a population proportion:
n = (Z^2 * p * (1-p)) / (E^2)
Where n is the sample size, Z is the z-score corresponding to the desired level of confidence (1.96 for 95% confidence), p is the estimated proportion of the population with the characteristic of interest (assumed to be 0.5 for this calculation), and E is the maximum margin of error desired (2% in this case). Plugging these values into the formula, we get:
n = (1.96^2 * 0.5 * (1-0.5)) / (0.02^2) = 803.84
Since this is a sample size estimate, we should round up to the next whole number, resulting in a sample size of 804.

Answer: Part 1: Dan, Part 2: 55%
Step-by-step explanation:
1. By noon, Jon has painted 1/5 (or 20%) of the hallway and Dan has painted 25% of the hallway. Therefore, Dan has painted more of the hallway than Jon.
2. In total, the two have painted 45% (20% + 25% = 45%) of the hallway by lunchtime. Therefore, 55% (100% - 45% = 55%) needs to be painted after lunch.

Sort 3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5 using quicksort with median-of-three partitioning and a cutoff of 3. The three elements are not pre-sorted when choosing pivot and pivot moved to end in each step. Show all steps.
Using quicksort with median-of-three partitioning and a cutoff of 3. we will get 1, 1, 3, 2, 3, 4, 5, 5, 5, 6, 9.
The Original input is 3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5.
We get on the basis of the median after sorting the first, middle, and final elements 3, 1, 4, 1, 5, 5, 2, 6, 5, 3, 9.
As a result, we select pivot = 5. It also provides after the pivot is removed or hidden 3, 1, 4, 1, 5, 3, 2, 6, 5, 5, 9.
It is necessary to swap the two fives. However, in the subsequent swap, p and q cross. turn is traded back with the p:
3, 1, 4, 1, 5, 3, 2, 5, 5, 6, 9
It is now time to quickly sort the first eight elements of the array in a recursive fashion:3, 1, 4, 1, 5, 3, 2, 5,
and after sorting the three relevant elements, we get 1, 1, 4, 3, 5, 3, 2, 5.
As a result, we select the pivot value of 3, and after hiding this pivot once more, we get:
1, 1, 4, 2, 5, 3, 3, 5
A switch takes place between 4 and 3: 1, 1, 3, 2, 5, 4, 3, 5
Now, because the next swap crosses the pointer, the pivot needed to be swapped: 1, 1, 3, 2, 3, 4, 5,
and the following is the result: 1, 1, 3, 2, 3, 4, 5, 5, 5, 6, 9

What is the solution of the inequality −3x−3>12 ?
Answer:
[tex]x < -5[/tex]
Step-by-step explanation:
-3x-3>12
Divide by -3, since you are dividing by a negative, flip the equality sign:
x+1<-4
Subtract 1 from both sides:
x<-5
Hello,
I hope you and your family are doing well!
To solve the inequality −3x−3>12, you can start by moving everything to one side of the inequality by adding 3 to both sides. This gives you −3x>15.
Next, you can divide both sides of the inequality by -3 to get x<-5.
Finally, you can simplify the inequality to its final form by flipping the direction of the inequality symbol, since you divided it by a negative number. This gives you the final solution: x>-5.
So, the solution to the inequality −3x−3>12 is x>-5. This means that any value of x that is greater than -5 will satisfy the inequality.
The answer is: x > -5

What is the equation in slope-intercept form of the line that passes through the point (3,4) and is parallel to the line represented by y=3x−2?
y=3x+7y
y=3x−5y
y=−3x+5y
y=−3x−7
The equation of the line in slope intercept form that passes through the point (3,4) and is parallel to the line represented by y=3x−2 is y = 3x - 5.
How to find equation of a line?The equation of a line can be represented in slope intercept form as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the line that passes through the point (3,4) and is parallel to the line represented by y = 3x − 2.
Parallel line have the same slope. Therefore, the slope of the line is 3.
Let's find the y-intercept using (3, 4).
y = 3x + b
4 = 3(3) + b
4 - 9 = b
b = -5
Therefore, the equation is y = 3x - 5
