Find cos(A), sin(A), and tan(A) for triangle ABC.

Answer: -14.9 and 2.1

Step-by-step explanation:

If you take -6.4 - 8.5 in one direction you get -14.9 .

And if you add them together (-6.4 + 8.5) you get 2.1,

those are two possible values depending on if you add or subtract the 8.5 .

The area of the shaded region is 176.5 square centimeters rounded up to one decimal place.

To get the area of the shaded region, we subtract the area of the sector from the area of the triangle as follows:

The angle m∠AOB = 180° - (34 + 90) {sum of interior angles of a triangle}

m∠AOB = 56°

area of sector = 56/360 × 22/7 × 26 cm × 26 cm

area of sector =14872/45 cm²

area of sector = 330.4888 cm²

area of the triangle = 1/2 × 26 cm × 39 cm

area of the triangle = 507 cm²

area of the shaded region = 507 cm² - 330.4888 cm²

area of the shaded region = 176.5111 cm²

Therefore, the area of the shaded region is 176.5 square centimeters rounded up to one decimal place.

The cafeteria earned $945 from all of the lunches sold on Friday.

percentage, a relative value indicating hundredth parts of any quantity.

Let us calculate the number of students who bought each pizza.

Number of students who bought cheese pizza = 50% of 270 = 0.5 x 270 = 135

Number of students who bought pepperoni pizza = 40% of 270 = 0.4 x 270 = 108

Total lunches sold = Number of cheese pizzas sold + Number of pepperoni pizzas sold + Number of fried chicken sold

= 135 + 108 + 27

= 270

Therefore, a total of 270 lunches were sold on Friday.

To calculate how much money the cafeteria earned from all of the lunches, we can multiply the total number of lunches sold by the cost of each lunch:

Total earnings = Total lunches sold x Cost per lunch

= 270 x $3.50

= $945

Therefore, the cafeteria earned $945 from all of the lunches sold on Friday.

The original amount borrowed was approximately $34,211.1.

To compute the first sum acquired, we can involve the recipe for the current worth of a customary annuity, which addresses a progression of equivalent installments made toward the finish of every period. The recipe is:

PV = [tex]PMT * (1 - (1 + r)^{(-n)}) / r[/tex]

where PV is the present value, PMT is the payment amount, r is the interest rate per period, and n is the total number of periods.

In this case, we have monthly payments, so we need to convert the APR to a monthly interest rate by dividing it by 12. We also have a 4-year loan, which means 48 monthly payments.

APR = 9.25%

Monthly interest rate = APR / 12 = 0.0925 / 12 = 0.00771 (rounded to five decimal places)

Total number of payments = 48

Total amount of payments = $4,200.0

Substituting these values into the formula, we get:

PV =[tex]PMT * (1 - (1 + r)^{(-n)}) / r[/tex]

PV = [tex]$4,200.0 * (1 - (1 + 0.00771)^{(-48)}) / 0.00771[/tex]

PV = $4,200.0 x (1 - 0.5180) / 0.00771

PV = $34,211.1 (rounded to the nearest tenth)

Therefore, the original amount borrowed was approximately $34,211.1.

The measure of the arc of the ferris wheel in which the lines of sight intersect is approximately 320.1 degrees.

An arc is a segment of a curved line or curve that forms part of a circle or other curved shape. In geometry, an arc is defined as a part of a curve that is contained between two endpoints, known as the arc's endpoints.

Let's draw a diagram to help us visualize the problem:

                      / \

                     /    \

               18 /        \

        /  40°                         \

     /                                      \

    A----------------------------------C

Here, the ride operator is standing at point A, and the ferris wheel is centered at point O. Points B and C represent the top and bottom of the ferris wheel, respectively.

We want to find the measure of the arc BC that is intercepted by the lines of sight of the ride operator.

First, we can use trigonometry to find the height of the ferris wheel. We know that angle AOB (the complement of angle AOC) is 50° (since the angles in a triangle add up to 180°). Using trigonometry, we have:

tan(50°) = height / 18

height = 18 * tan(50°) ≈ 22.6

So the height of the ferris wheel is approximately 22.6 meters.

Next, we can use the height to find the distance between points B and C. Since the ferris wheel is a circle, we know that the distance between B and C is twice the height:

BC = 2 * height ≈ 45.2

So the distance between points B and C is approximately 45.2 meters.

Finally, we can use the distance between points A and O (which is 18 meters) and the distance between points B and O to find the angle that the lines of sight make with each other. Let's call this angle x. Using trigonometry again, we have:

tan(x) = height / (18 - r)

where r is the radius of the ferris wheel. Since we know that the distance between A and O is 18 meters and the height is approximately 22.6 meters, we can solve for r:

tan(x) = 22.6 / (18 - r)

(18 - r) * tan(x) = 22.6

18 - r = 22.6 / tan(x)

r = 18 - 22.6 / tan(x)

We also know that the distance between B and O is equal to the radius, so we have:

r = BC / 2 ≈ 22.6

Now we can solve for x:

18 - 22.6 / tan(x) ≈ 22.6

tan(x) ≈ 22.6 / (18 - 22.6)

tan(x) ≈ -5.65

x ≈ -79.9° (using arctan on a calculator)

Note that we get a negative angle because the lines of sight are intersecting below the horizontal line passing through the ferris wheel.

Finally, we can find the measure of the arc BC by using the central angle formula:

arc BC = x + 40° ≈ -39.9°

Again, we get a negative value because the arc is measured clockwise from point B. To get the positive measure of the arc, we can subtract this value from 360°:

arc BC ≈ 320.1°

So the measure of the arc of the ferris wheel in which the lines of sight intersect is approximately 320.1 degrees.

There are five letters in the word "AGAIN". To find the number of f-words that can be made using all these letters, we need to find the number of permutations of these letters.

The number of permutations of a set of n elements is given by n!. However, in this case, we have two "A"s in the word "AGAIN". This means that we cannot simply use n! to calculate the number of permutations.

Instead, we need to use the formula for permutations with repeated elements, which is:

To solve this problem, we can use the formula for work rate:
Work rate = (Number of workers) × (Time taken) / (Number of houses built)

We can plug in the given values to find the work rate for the 12 builders:
Work rate = (12 builders) × (7 days) / (2 houses) = 42 builder-days / house

Now we can use this work rate to find the time taken for 15 builders to build the same amount of houses:
42 builder-days / house = (15 builders) × (Time taken) / (2 houses)
Solving for Time taken, we get:
Time taken = (42 builder-days / house) × (2 houses) / (15 builders) = 5.6 days

Therefore, it will take 15 builders 5.6 days to build the same amount of houses.
To convert this to days and hours, we can multiply the decimal part of the answer by 24 (since there are 24 hours in a day):
0.6 days × 24 hours/day = 14.4 hours

So the final answer is 5 days and 14.4 hours, or 5 days and 14 hours and 24 minutes.

The expense function consists of two parts: the monthly payment for the car loan and the monthly cost of depreciation. The monthly payment can be calculated using the following formula: P = (r(PV)) / (1 - (1+r)^(-n)) = $1,062.66 per month. The depreciation function will be a straight line from $54,000 to $0 over a period of 10 years (or 120 months).

A depreciation function is a mathematical model that explains how the worth of an object decreases over time. It denotes the pace at which the worth of an asset depreciates over time.

In the given question,

a. The expense function will consist of two parts: the monthly payment for the car loan and the monthly cost of depreciation. The monthly payment can be calculated using the following formula:

[tex]P = (r(PV)) / (1 - (1+r)^(-n))[/tex]

where P is the monthly payment, r is the monthly interest rate (4.875%/12 = 0.40625%), PV is the present value of the loan (54,000 - 8,000 = 46,000), and n is the total number of payments (4 years x 12 months per year = 48). Plugging these values into the formula, we get:

[tex]P = (0.0040625(46000)) / (1 - (1 + 0.0040625)^(-48)) = $1,062.66 per month[/tex]

The depreciation function will be a straight line from $54,000 to $0 over a period of 10 years (or 120 months), so the monthly depreciation can be calculated as:

d = (54000 - 0) / 120 = $450 per month

Therefore, the expense function E(x) and depreciation function D(x) are:

E(x) = 1062.66 + 450x

D(x) = 450x

where x is the number of months since the car was purchased.

b. The graph of the expense function and depreciation function on the same axes is attached.

c. At the intersection point (around 66 months), the monthly loan payment becomes greater than the monthly depreciation cost, meaning that Winnie is paying more each month than the car is depreciating. After 66 months, the expense function is increasing faster than the depreciation function, so the total value of the car is decreasing rapidly. By the end of 120 months, the car will have depreciated to a value of $0 and Winnie will have paid a total of $62,719.20 in loan payments.

The probability that at least 3 of the selected human resource managers say job applicants should follow up within two weeks is 0.55.

From the question, we are to determine the probability that at least 3 of the managers say job applicants should follow up within two weeks

This problem requires the use of the binomial probability distribution. We are given that the probability of success (a human resource manager saying that job applicants should follow up within two weeks) is p = 0.57. The number of trials is n = 6.

To find the probability that at least 3 of the selected human resource managers say job applicants should follow up within two weeks, we need to find the sum of the probabilities of 3, 4, 5, and 6 successes. We can use the binomial probability formula to find these individual probabilities and add them up:

P(X ≥ 3) = P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)

Where X is the number of successes.

Using the binomial probability formula, we get:

P(X = k) = (n Ck) * p^k * (1-p)^(n-k)

Where (n Ck) = n! / (k! * (n-k)!)

So,

P(X = 3) = (6 C3) * 0.57^3 * (1-0.57)^(6-3) = 0.307

P(X = 4) = (6 C4) * 0.57^4 * (1-0.57)^(6-4) = 0.185

P(X = 5) = (6 C 5) * 0.57^5 * (1-0.57)^(6-5) = 0.051

P(X = 6) = (6 C6) * 0.57^6 * (1-0.57)^(6-6) = 0.007

So,

P(X ≥ 3) = P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) = 0.307 + 0.185 + 0.051 + 0.007 = 0.55

We can solve for p by isolating it on one side of the inequality symbol. First, we'll subtract 7 from both sides:

55 - 7 < -12p

48 < -12p

Next, we'll divide both sides by -12. Since we're dividing by a negative number, we'll need to flip the direction of the inequality:

The difference in elevation for A and B is the difference in elevation for line AB minus the slope correction: D = 330.422m

The slope correction formula is:
C = L * (D^2 / (2 * R)), Where:
- C is the slope correction
- L is the horizontal length of the line
- D is the difference in elevation
- R is the Earth's radius

For line BC, we can plug in the given values to find the slope correction:
C = 660.97m * (10.85m^2 / (2 * 6371000m))
C = 0.059m

For line AB, we need to find the difference in elevation first. We can do this by subtracting the slope correction from the slope distance:
D = 330.49m - 0.059m
D = 330.431m

Now we can plug in the values for line AB into the slope correction formula: C = 330.431m * (330.431m^2 / (2 * 6371000m))  C = 0.009m

The difference in elevation for A and B is the difference in elevation for line AB minus the slope correction:
D = 330.431m - 0.009m
D = 330.422m

Therefore, the difference in elevation for A and B is 330.422m.

The solutions to this 3x^(2)-4x=-2  are x=(2/3)+i*√(2/9) or x=(2/3)-i*√(2/9).

To solve this equation by completing the square, we need to first rearrange the equation and then complete the square for the x terms. Here are the steps:

1. Rearrange the equation:
3x^(2)-4x=-2 becomes 3x^(2)-4x+2=0

2. Divide the entire equation by the coefficient of the x^(2) term:
(3x^(2)-4x+2)/3=0/3 becomes x^(2)-(4/3)x+(2/3)=0

3. Complete the square by adding the square of half the coefficient of the x term to both sides of the equation:
x^(2)-(4/3)x+(2/3)+(4/3)^(2)/4=(4/3)^(2)/4 becomes x^(2)-(4/3)x+(4/9)=(4/3)^(2)/4-(2/3)

4. Simplify the right side of the equation:
(4/3)^(2)/4-(2/3)=(16/9)/4-(2/3)=(4/9)-(2/3)=(4/9)-(6/9)=-(2/9)

5. Factor the left side of the equation:

6. Take the square root of both sides of the equation:
x-(2/3)=+/-sqrt(-(2/9))

7. Solve for x:
x=(2/3)+/-sqrt(-(2/9)) becomes x=(2/3)+i*sqrt(2/9) or x=(2/3)-i*sqrt(2/9)

Answer:

Proof:

Draw circle C with center at point A and radius AD = CD = DE.

Draw point P outside the circle C.

Draw segment AP and extend it to intersect the circle at point B.

Draw segment BD.

Draw segment CP.

Note that triangle BCD is isosceles, since CD = BD. Therefore, angle BDC = angle CBD.

Since angle BDC is an inscribed angle that intercepts arc BC, and angle CBD is an angle that intercepts the same arc, then angle BDC = angle CBD = 1/2(arc BC).

Since CD = DE, then angle CED = angle CDE. Therefore, angle DCE = 1/2(arc BC).

Since angles BDC and DCE are equal, then angles BDC and CBD are also equal, and triangle BPC is isosceles. Therefore, segment BP = segment PC.

Since BP = PC, then segment CP is perpendicular to segment BD, by the Converse of the Perpendicular Bisector Theorem.

Therefore, segment CP is a tangent to circle C at point B.

Hence, the proof is complete.

The solution to the system of equations using the substitution method is (7,2).

No, the substitution approach cannot be used to solve every system of equations. It can be challenging to replace one equation with another in some systems because they feature equations that are challenging or impossible to solve for one variable in terms of the other. Other approaches, such graphing or elimination, could be more useful in such circumstances.

Given that, the two equations are:

x= 4y - 1

3x + 2y = 25

Substitute x = 4y - 1 into the second equation:

3(4y - 1) + 2y = 25

12y - 3 + 2y = 25

14y - 3 = 25

14y = 28

y = 2

Substitute the value of y in equation:

x = 4y - 1

x = 4(2) - 1

x = 7

Hence, the solution to the system of equations using the substitution method is (7,2)
