In a case whereby A ship travels due west for 94 miles. It then travels in a northwest direction for 119 miles and ends up 173 miles from its original position the degrees north of west it turned is 72°
How can the degree be calculated?From trigonometry, the law of cosines states the side c of a triangle can be found as
c² = a² + b² - 2abcos(C)
where
C = angle opposite to side c.
a and = lengths of the other sides.
a = 94, b = 119, c = 173.
c² = a² + b² - 2abcos(C)
173² = 94² + 119² - 2 x 94 x 119cos(C)
22327cos(C) = -6932
cos(C) = -6932/22327
C = arccos(-6932/22327)
C = 108º.
Then,
T = 180 - C
= 180 - 108 = 72º.

Fergus and his best friend went to a movie
and bought popcorn. They split the cost
evenly, each paying $17. How much was the
total cost of the movie and popcorn? If x
equals the total cost, choose the equation
that solves the problem.
O x/2 = 17
Ox-17 = 2
Ox+17 = 2
2x = 17
Answer:
x / 2 = 17
Step-by-step explanation:
Since we're told that there are 2 friends, they split the cost evenly, and they each paid $17 individually, we'd have to use the equation x / 2 = 17 to find the total cost.
If you were to solve, you'd find that the total cost was $34 as 2 * 17 = 34 and 34 / 2 = 17

Based on the given transactions, we can prepare the accounting equation as follows:
a. Started business with Cash Rs. 250,000.
Assets: Cash = Rs. 250,000
b. Purchased goods amounting to Rs. 45,000 on credit from Harish.
Assets: Cash = Rs. 250,000, Inventory = Rs. 45,000
Liabilities: Accounts Payable = Rs. 45,000
c. Goods costing to Rs. 80,000 was sold for Rs. 1,25,000 on credit.
Assets: Cash = Rs. 250,000, Accounts Receivable = Rs. 1,25,000
Inventory: Rs. 45,000 - Rs. 80,000 = Rs. -35,000 (Assuming no additional purchases or returns)
Liabilities: Accounts Payable = Rs. 45,000
Capital: Retained Earnings = Rs. 1,25,000 - Rs. 80,000 = Rs. 45,000
d. Salaries outstanding Rs. 5,000.

A circle C has center at the origin and radius 5 . Another circle K has a diameter with one end at the origin and the other end at the point (0,15) . The circles C and K intersect in two points. Let P be the point of intersection of C and K which lies in the first quadrant. Let (r,θ) be the polar coordinates of P , chosen so that r is positive and 0≤θ≤2 . Find r and θ .
The value of R and θ is 6.18 and 53.13 degrees, under the condition that a circle C has center at the origin and radius 5 .
In order to evaluate the equation of the circle K. The diameter of K has endpoints at the origin and (0,15). Then, the center of K is at (0,7.5) and its radius is 7.5. Therefore, the evaluated equation of K is
x² + (y-7.5)² = 56.25.
The equation of circle C is x² + y² = 25.
The two circles intersect at two points. Now we have to evaluate the coordinates of these points.
Staging y = 5 - x² in the equation of K,
we get
x² + (5-x²-7.5)² = 56.25.
Applying simplification on this equation
x⁴ - 10x² + 31.25 = 0.
Calculating this quadratic equation gives us
x² = 5 ± √(10)/2.
If P lies in the first quadrant,
we choose x² = 5 + √(10)/2 and y = √(25-x²) to get P in Cartesian coordinates.
Converting P to polar coordinates gives us
r = √(x²+y²) and θ = arctan(y/x).
Staging x = √(5+√(10)/2) and y = √(25-x²) in these equations gives us
r ≈ 6.18 and θ ≈ 0.93 radians.
Using this formula to convert into degree
Rad × 180/π
= 0.93 × 180/π
≈ 53.13 degrees
Therefore, r ≈ 6.18 and θ ≈ 53.13 degrees.

If tanA= 40/9 and sin B = 45/53
and angles A and B are in
Quadrant I, find the value of tan (A-B).
The value of tan (A-B) is equal to 715/2052.
To find the value of tan(A - B), we can use the trigonometric identity:
tan(A - B) = (tan(A) - tan(B))/(1 + tan(A)tan(B))
Given that tan(A) = 40/9 and sin(B) = 45/53, we can determine the values of cos(B) and tan(B) using the Pythagorean identity:
sin^2(B) + cos^2(B) = 1
cos(B) = sqrt(1 - sin^2(B))
cos(B) = sqrt(1 - (45/53)^2)
cos(B) = sqrt(1 - 2025/2809)
cos(B) = sqrt(784/2809)
cos(B) = 28/53
tan(B) = sin(B)/cos(B)
tan(B) = (45/53)/(28/53)
tan(B) = 45/28
Now we can substitute the values into the formula for tan(A - B):
tan(A - B) = (tan(A) - tan(B))/(1 + tan(A)tan(B))
tan(A - B) = (40/9 - 45/28)/(1 + (40/9)(45/28))
tan(A - B) = [(1120/252 - 405/252)] / (1 + (1800/252))
tan(A - B) = (715/252) / (2052/252)
tan(A - B) = 715/2052
Therefore, tan(A - B) is equal to 715/2052.

The given text presents a map of South Africa with various locations marked. However, important information such as the scale of the map and the number of provinces is missing. Without the scale, we cannot accurately determine distances or calculate probabilities. Similarly, the absence of information regarding the provinces prevents us from calculating the probability of selecting a specific province. Therefore, based on the given text, we can only answer the first two questions, which involve the type of scale and the general direction between two locations.
1. The type of scale given in the diagram is a ratio scale, specifically a linear scale. It represents the relationship between map distance and actual distance in a straight line.
Interpretation of the given scale:
The scale on the map is not clearly visible in the provided text. However, it is typically written as a fraction or ratio, where the numerator represents the map distance and the denominator represents the corresponding actual distance on the ground. For example, a scale of 1:1,000,000 means that 1 unit on the map represents 1,000,000 units in the real world.
2. The general direction of Badplaas from Colesburg is to the northeast.
3. To determine the actual straight-line distance between East London and Bloemfontein, we would need the scale from the map. However, the scale is not provided in the given text, making it impossible to calculate the distance accurately.
4. Stellenbosch is located in the Western Cape province on the map.
5. To calculate the probability of randomly selecting the Western Cape province in South Africa, we would need the total number of provinces in South Africa and the number of provinces that belong to the Western Cape. However, this information is not provided in the given text, so it is not possible to calculate the probability.

O is the center of the regular nonagon below. Find its area. Round to the nearest tenth if necessary.
Answer:
471.1 square units
Step-by-step explanation:
A regular nonagon is a 9-sided polygon with sides of equal length.
The apothem of a regular polygon is the distance from the center of the polygon to the midpoint of one of its sides.
Therefore, the given diagram shows a regular nonagon with an apothem of 12 units.
The side length (s) of a regular polygon can be calculated using the apothem formula:
[tex]\boxed{\begin{minipage}{5.5cm}\underline{Apothem of a regular polygon}\\\\$a=\dfrac{s}{2 \tan\left(\dfrac{180^{\circ}}{n}\right)}$\\\\where:\\\phantom{ww}$\bullet$ $s$ is the side length.\\ \phantom{ww}$\bullet$ $n$ is the number of sides.\\\end{minipage}}[/tex]
Given values:
a = 12n = 9Substitute the given values into the formula to create an expression for the side length (s):
[tex]12=\dfrac{s}{2 \tan\left(\dfrac{180^{\circ}}{9}\right)}[/tex]
[tex]12=\dfrac{s}{2 \tan\left(20^{\circ}\right)}[/tex]
[tex]s=24 \tan\left(20^{\circ}\right)[/tex]
The standard formula for an area of a regular polygon is:
[tex]\boxed{\begin{minipage}{6cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{n\cdot s\cdot a}{2}$\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the length of one side.\\ \phantom{ww}$\bullet$ $a$ is the apothem.\\\end{minipage}}[/tex]
Substitute the found expression for s together with n = 9 and a = 12 into the formula and solve for A:
[tex]A=\dfrac{9 \cdot 24 \tan(20^{\circ}) \cdot 12}{2}[/tex]
[tex]A=1296\tan(20^{\circ})[/tex]
[tex]A=471.705423...[/tex]
[tex]A=471.7\; \sf square\;units\;(nearest\;tenth)[/tex]
Therefore, the area of a regular nonagon with an apothem of 12 units is 471.1 square units, rounded to the nearest tenth.

Solve and graph. |2x(x-1)+12|<=18
The solution of the inequality is -1 ≤ x ≤ 3.
To solve the inequality |2x(x-1)+12| ≤ 18, we can break it down into two separate inequalities:
2x(x-1) + 12 ≤ 18
-(2x(x-1) + 12) ≤ 18
Solving the first inequality:
2x(x-1) + 12 ≤ 18
2x² - 2x + 12 ≤ 18
2x² - 2x - 6 ≤ 0
Solving the second inequality:
-(2x(x-1) + 12) ≤ 18
-2x(x-1) - 12 ≤ 18
-2x² + 2x - 12 ≤ 18
2x² - 2x + 30 ≤ 0
Now, let's solve each inequality separately.
For the first inequality, 2x² - 2x - 6 ≤ 0:
We can factor this quadratic equation:
(2x + 2)(x - 3) ≤ 0
To determine the sign of the inequality, we need to consider the intervals where the expression is positive or negative. We set each factor equal to zero to find the critical values:
2x + 2 = 0 => x = -1
x - 3 = 0 => x = 3
Plotting these critical values on a number line and testing intervals, we find that the solution is -1 ≤ x ≤ 3.
For the second inequality, 2x² - 2x + 30 ≤ 0:
This quadratic equation does not have real solutions, so there are no solutions to this inequality.
Combining the solutions from both inequalities, we have -1 ≤ x ≤ 3.
To graph the solution, we plot the interval -1 ≤ x ≤ 3 on the number line. The shaded region on the number line represents the solution set.

make t the subject of the formula k=2(t+3)/t-3
t = (6 + 3k)/(k - 2) is the formula for t in the equation k=2(t+3)/t-3.
The given equation is k=2(t+3)/t-3.
We need to isolate t on one side of the equation.
Let's start by cross-multiplying:
k(t - 3) = 2(t + 3)
Expanding the brackets:
kt - 3k = 2t + 6
Now, let's gather all the terms with t on one side and all the constant
terms on the other side:
kt - 2t = 6 + 3k
Factoring out t on the left side:
t(k - 2) = 6 + 3k
Finally, we can solve for t by dividing both sides of the equation by (k - 2):
t = (6 + 3k)/(k - 2)
Therefore, t is the subject of the formula, and it is given by t = (6 + 3k)/(k - 2).

Here,
We have that in line CHF, it has two given and one unknown angle.
The total angle of one straight line is 180.
Given that:
a = 180 - 50 -70 = 60
The angle intersecting the CHFD line can be computed by the the total angle inside the triangle.
Angle on EFH would give 180-40-60 = 80 and on EFD the angle would be 100 from 180-80.
Since angle C is congruent to the angle EFD.
c = 100
Take note that in a 4 sided polygon (GEFH), the total exterior angle is 360 degrees.
The different angle would be
angle GHF = 50 + a = 50+60 = 110
angle EFH = 80
angle FEG = 180- c = 180-100 = 80
ANGLE EGH = 360 - GHF -EFH -FEG = 360 - 110-80-80 = 90
since angle AG is congruent to EGH, we can calculate for the angle b which is congruent to its opposite. This would give us formula of
360 = (90+90) + (b) +(b)
360 = 180 +2b
b = 90
Hence, The solution is: the value of the angles a, b and c are : a = 60, b = 90, c = 100.

You could also just do 15 × 5 to get 75 :)
The table of values below represents a linear function and shows the amount of snow that has fallen since a snowstorm began. What is the rate of change?
Snowfall Amount
Length of Snowfall
(hours)
Amount of Snow on the Ground
(inches)
0
3.3
0.5
4.5
1.0
5.7
1.5
6.9
2.0
8.1
1.2 inches per hour
2.4 inches per hour
3.3 inches per hour
5.7 inches per hour
The average rate of change for the snowfall amount is given as follows:
2.4 inches per hour.
How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function.
The change in the output is given as follows:
8.1 - 3.3 = 4.8.
(output is the amount of snow).
The change in the input is given as follows:
2 - 0 = 2.
(input is the time in hours).
Hence the average rate of change of the snowfall over time is given as follows:
4.8/2 = 2.4 inches per hour.
(change in the snowfall divided by the change in time).
Missing InformationThe table is given by the image presented at the end of the answer.

Last year, the Ross family spent $3,336 for electricity. They are opting to use balanced billing for next year. What will their monthly payment be?
Using balanced billing, the monthly payment is $278
What will be their monthly payment?Using balanced billing to determine their monthly payment, we simply need to divide their total annual payment by the total number of months in a year. This will result to dividing the entire annual bill by 12 to determine the monthly payment.
Given that the Ross family spent $3,336 for electricity last year, we can calculate their monthly payment as follows:
Monthly payment = Total cost / Number of months
Monthly payment = $3,336 / 12
Monthly payment = $278
Therefore, the Ross family's monthly payment for balanced billing will be approximately $278.

A designer is making a sample design that will use 3 different kinds of tiles. The designer has 9 different kinds of tiles from which to choose. How many possible combinations of tiles can the designer choose? The designer will create a sample design by placing 3 tiles side by side. How many different sample designs can the designer make from the 3 chosen tiles?
The designer can choose from 84 possible combinations of tiles, and they can create 6 different sample designs using the 3 chosen tiles when placing them side by side.
To determine the number of possible combinations of tiles that the designer can choose, we can use the concept of combinations.
Since the designer has 9 different kinds of tiles and wants to choose 3 of them, we can calculate the number of combinations using the formula for combinations, which is [tex]nCr = n! / (r! \times (n - r)!).[/tex]
Number of combinations of tiles = 9C3 [tex]= 9! / (3! \times (9 - 3)!)[/tex]
Simplifying further:
[tex]9! = 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1[/tex]
[tex]3! = 3 \times 2 \times 1[/tex]
[tex](9 - 3)! = 6! = 6 \times 5 \times 4 \times 3 \times 2 \times 1[/tex]
Plugging these values into the formula:
Number of combinations of tiles[tex]= 9 \times 8 \times 7 / (3 \times 2 \times 1 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1)[/tex]
Simplifying the expression:
Number of combinations of tiles = 84
The designer can choose from 84 possible combinations of tiles, and they can create 6 different sample designs using the 3 chosen tiles when placing them side by side.
Therefore, the designer can choose from 84 possible combinations of tiles.
Now, let's calculate the number of different sample designs the designer can make using the 3 chosen tiles.
Since the tiles are placed side by side, the order of the tiles matters.
To calculate the number of different arrangements, we can use the concept of permutations.
Number of sample designs = 3!
Calculating:
[tex]3! = 3 \times 2 \times 1 = 6[/tex]
Therefore, the designer can create 6 different sample designs using the 3 chosen tiles when placing them side by side.

Why can you not have 1 imaginary solution?
You cannot have 1 imaginary solution because the quadratic equation must have either two real solutions or two complex solutions
What is an imaginary solution?In mathematics, the discriminant (D = b2 - 4ac) aids in identifying the kind of solutions to quadratic equations of the form ax2 + bx + c = 0.
There are two unique real solutions if the discriminant is positive. There is only one viable option if the discriminant is zero. There are no practical solutions, however, if the discriminant is negative.
The quadratic equation in this instance has two complex solutions that are conjugates of one another. Because the quadratic equation must have either two real solutions or two complex solutions, there can never be just one hypothetical solution.

PLEASE HELP!!!!!!
it’s a division equation
Answer:
x+1
DOMAIN: x [tex]\neq[/tex] -5
Step-by-step explanation:
We can factor [tex]x^{2}[/tex]+6x+5 as (x+1)(x+5) since this expands to [tex]x^{2}[/tex]+5*x+1*x+5*1, which is [tex]x^{2}[/tex]+6x+5.
Now, we have:
[tex]\frac{(x+1)(x+5)}{(x+5)}[/tex]
We can cancel out x+5, because this expression is the same as (x+1)*[tex]\frac{x+5}{x+5}[/tex], which is (x+1).
HOWEVER, the denominator cannot be equal to zero because that will make the expression undefined (you can't divide by zero). So, since x+5[tex]\neq[/tex]0, x[tex]\neq[/tex]-5.
