Answer:

(1,1); (2,0) and (-1,-3)

Step-by-step explanation:

Given

\(y=-x+2\) ---- (1)

\(y = 2x - 1\) --- (2)

\(y = x -2\) ---- (3)

Required

The vertices of the triangle

To do this, we simply equate the equations.

Equate (1) and (2)

\(-x + 2 = 2x - 1\)

Collect like terms

\(-x-2x=-2-1\)

\(-3x=-3\)

Divide by -3

\(x =1\)

Substitute \(x =1\) in (1), to get the y-coordinates

\(y=-x+2\)

\(y=-1+2\)

\(y=1\)

So, the coordinate is: (1,1)

Equate (1) and (3)

\(-x + 2 = x - 2\)

Collect like terms

\(-x -x = -2 - 2\)

\(-2x = -4\)

Divide by -2

\(x=2\)

Substitute \(x=2\) in (1) to get the y coordinate

\(y=-x+2\)

\(y=-2+2\)

\(y=0\)

So, the coordinate is (2,0)

Equate (2) and (3)

\(2x - 1 = x - 2\)

Collect like terms

\(2x-x=1-2\)

\(x=-1\)

Substitute \(x=-1\) in (2) to get the y coordinates

\(y = x -2\)

\(y=-1-2\)

\(y=-3\)

So, the coordinate is (-1,-3)

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.

A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.

B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.

\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.

That leaves \(27-14=13\) matches. These represent the matches team lost.

Finally, the answers are below.

\(A)29\)
\(B)13\)

Answer:

  a) 29 points

  b) 13 losses

Step-by-step explanation:

You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.

The number of points the team has is ...

  P = 3W +D

  P = 3(8) +(5) = 29

The team has 29 points.

You want the number of losses the team has if it has 54 points and 12 draws after 39 games.

The number of wins is given by ...

  P = 3W +D

  54 = 3W +12

  42 = 3W

  14 = W

Then the number of losses is ...

  W +D +L = 39

  14 +12 +L = 39 . . . substitute the known values

  L = 13 . . . . . . . . . . subtract 26 from both sides

The team lost 13 games.

__

Additional comment

In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

Assuming that both boats are travelling in straight paths, the angle that is between their paths to the nearest degrees is =34°

A triangle is a type of polygon that has three pointed edges.

A polygon is defined as a closed object that is made up of line segments in a two dimensional plane.

Other examples of polygon include the following:

The angle between the paths of the boats can be calculated using the formula Cos θ = a/b

Where b = 18km/h

a = 15km/h

Cos θ = 15/18

cos θ = 0.83

Therefore, θ = Cos¹0.83

θ = 33.9

θ = 34°

In conclusion, the angle that is between their paths to the nearest degrees is =34°

Step-by-step explanation:

To dilate a point at a point, you start by selecting a center of dilation and a scale factor.

Then, for each point that you want to dilate, you do the following:

For example, if you wanted to dilate point P by a scale factor of 2, with the center of dilation at O, you would draw a line segment from O to P, double its length, and then draw a new line segment from O to the new point, using the new length that you calculated. The new point would be the point that you arrive at when you complete this line segment.

The number of the elements which are present in the set B is given by the term 85.

The symbol "" can be used to represent the intersection of sets. According to the definition given above, the intersection of two sets A and B is the collection of all the items that are shared by both sets. The intersection of A and B can be conceptualised as A B.

The largest set containing all the items shared by X and Y is the intersection of two given sets, let's say X and Y. The intersection of two sets can be an empty set, meaning that there are no elements in the intersection set, or it can be a set containing at least one member. If A and B are two sets with the relationship A B =, then A and B are referred to be disjoint sets. Hence, there are no elements at the point where A and B meet.

The set A contains 57 elements so,

n(A) = 57

total number elements in either set A or set B is 136.

n(A ∪ B) = 136

if the sets A and B have 6 elements in common,

n(A ∩ B) = 6

By using the formula for Union and Intersection of Sets,

n (A ∪ B) = n (A) + n (B) – n (A ∩ B)

136 = 57 + n(B) - 6

136 = 51 + n(B)

n(B) = 85.

Therefore, the number of element in B is 85.

the Greatest Common Divisor is 252 and it can be expressed as the linear combination -2 * 6,066 + 3 * 2,286.

The greatest common divisor (GCD) is the biggest positive integer that divides two or more integers without leaving a remainder. It's also referred to as the greatest common factor (GCF) or the highest common factor (HCF). The Euclidean procedure, which continually divides the greater of the two integers by the smaller until a remainder of zero is obtained, is one way to calculate the GCD. The GCD is a crucial idea in mathematics, notably in number theory, and it has several applications in other disciplines, such as computer science and encryption. Finding the greatest common divisor of the coefficients of a linear equation in two variables is another popular geometry task.

How to solve?

The Greatest Common Divisor of 6,066 and 2,286 can be expressed as 252 = 6,066 * (-2) + 2,286 * 3. So, the GCD is 252 and it can be expressed as the linear combination -2 * 6,066 + 3 * 2,286.

Rectangle has four sides. The total weight of the circle is 20 grams.

A rectangle is a 2D shape that has four sides, and the pair of opposite sides are equal and parallel to each other.

As it is given that the weight of the rectangle is 80 grams, and a rectangle is made up of two triangles. Therefore, the weight of each triangle can be written as,

\(\text{Weight of the reactangle} = \dfrac{\text{Total weight of the reactangle}}{\text{Number of Triangles}}\)

\(\text{Weight of the reactangle} = \dfrac{80}{2} = 40\rm\ grams\)

It is given that the total weight of the triangle is double the weight of the circle. therefore, the relationship can be written as,

\(\text{Weight of the triangle} = 2 \times \text{Weight of the circle}\)

\(40= 2 \times \text{Weight of the circle}\\\\\text{Weight of the circle} = 20\rm\ grams\)

Hence, the total weight of the circle is 20 grams.

The procedure for constructing a confidence interval is robust, meaning it remains reliable even when certain conditions are not perfectly met. When we say that the confidence interval is more robust with a larger sample size, we mean that it becomes more resistant to changes in the mean.

Here is a step-by-step explanation of why the confidence interval is more robust with a larger sample size:

1. A confidence interval is a range of values within which we can be confident that the true population parameter lies. It is typically constructed for the mean of a population, but can also be constructed for other parameters such as proportions or variances.

2. The construction of a confidence interval involves estimating the population parameter using sample data. The larger the sample size, the more data we have, which generally leads to a more accurate estimate of the population mean.

3. A larger sample size reduces the variability of the estimate of the mean. This means that the estimate is less likely to be influenced by random fluctuations in the data. As a result, the confidence interval tends to be narrower, indicating a higher level of precision.

4. With a larger sample size, the sample mean tends to be closer to the true population mean. This means that even if there are small deviations from the assumptions underlying the construction of the confidence interval, the estimate is less likely to be biased.

5. The robustness of the confidence interval is particularly important when dealing with non-normal or skewed data. In such cases, a larger sample size can help mitigate the impact of these departures from normality.

To summarize, the larger the sample size, the more resistant the mean estimate becomes, leading to a more robust confidence interval. This means that even if certain assumptions are not perfectly met, we can still have confidence in the interval estimate.

b. Using the accrual basis of accounting, Al's gross income for 2021 is $614,600.

c. Al should use the accrual basis of accounting for reporting his gross income.

a. Under the cash basis of accounting, income is recognized when it is received in cash. In this case, Al received cash of $516,600 for medical services in 2021. However, $37,200 of this amount was for services provided in 2020. Therefore, Al's gross income for 2021 using the cash basis is $516,600 - $37,200 = $479,400.

b. Under the accrual basis of accounting, income is recognized when it is earned, regardless of when the cash is received. In this case, Al earned $516,600 for medical services in 2021, including the $37,200 from 2020. Additionally, Al had accounts receivable of $88,000 at the end of 2021 for services rendered in 2021. Therefore, Al's gross income for 2021 using the accrual basis is $516,600 + $88,000 = $604,600.

c. It is advisable for Al to use the accrual basis of accounting because it provides a more accurate representation of his income by recognizing revenue when it is earned, even if the cash is received later.
