Find the distance between the two points (4, 1) and (10,9)

Answers

The distance between the two points is ten.

The distance between the two points (4, 1) and (10,9) is 10 units

Coordinates

Assume the points are A and B

The coordinates of the points are given as:

Point A = (4,1)Point B = (10,9)

Distance

The distance (d) between two points A and B is calculated as:

[tex]d = \sqrt{(x_1 -x_2)^2 + (y_1 -y_2)^2}[/tex]

So, the above equation becomes

[tex]d = \sqrt{(4-10)^2 + (1 -9)^2}[/tex]

[tex]d = \sqrt{100}[/tex]

Take the positive square root of 100

[tex]d = 10[/tex]

Hence, the distance is 10

kevin estimated the differncle between of 9/10 minus 4/8 to be 0 is his estimate reasonable explain

Answers

Answer:

No, it is not reasonable

Step-by-step explanation:

Writing 9/10 and 4/8 as fractions out of 100, and then as decimals

9/10 = 90/100 = 0.9

4/8 = 1/2 = 50/100 = 0.5

0.9 - 0.5 = 0.4

Not 0, like Kevin estimated

Answer: 4/8 = 0.5 and 9/10= 0.9. If you subtract 0.9 by 0.5, you end up with 0.4. I would say not reasonable.

Answer:

41 Degrees

Step-by-step explanation:

So basically you add the 72 and the other 72 to get 148.You obviously know the angle in between 72 and 72 is a right angle or 90 degrees.Then you add 148 and 90 to get 238.Then 360 - 238 is 122.Now you know all the angles.So we have to ask ourselves what is 148/360 simplified.It is 37/90.Now that we know that and we know that the radius is 10.We have to find the regular area which is 10 times 10 which is 100.Finally we need to figure out what part of 100 is 37/90 and it is 41.111111111111.Rounded it is 41.

The answer is 41 degrees

Plot the image of point B under a dilation about point P
with a scale factor of

Answers

Please find the attached file.

We have been given am image of point B on coordinate plane. We are asked to plot the mage of point B under a dilation about point P  with a scale factor of [tex]\frac{1}{2}[/tex].

To solve our given problem, we need to find vertical distance and horizontal distance between point B and point P.  

We can see that vertical distance is 4 units as shown in the attachment and horizontal distance is 6 units.

Since the scale of dilation is [tex]\frac{1}{2}[/tex], so the vertical distance between point P and B' would be [tex]\frac{1}{2}[/tex] of 4 that is [tex]\frac{1}{2}(4)=2[/tex].

The horizontal distance between point P and B' would be [tex]\frac{1}{2}[/tex] of 6 that is [tex]\frac{1}{2}(6)=3[/tex].

Now we will count 3 units to left of point P and 2 units upwards. That will be the position of point B'.

The below-attached graph represents the image of point B under a dilation about point P with a scale factor of 1/2.

To plot the image of point B under a dilation about point P with a scale factor of 1/2, follow these steps:

Draw point P on the coordinate plane at any location.From point P, move vertically 6 units up and label the new point as B.From point P, move horizontally 4 units to the left and label the new point as B'.

The point where this line intersects the vertical line through point C will be the image of point B under the dilation with a scale factor of 1/2.

Thus, the image of point B will be half as far away from point P as point B.

Hence, the below-attached graph represents the image of point B under a dilation about point P with a scale factor of 1/2.

The shoes are on sale for 39.99. If they were marked down 20%, what was the original price?

Answers

Final answer:

The original price comes out to $49.99 when rounded to the nearest cent.

Explanation:

To determine the original price of an item that has been marked down by 20%, we need to understand that the current price represents 80% of the original price (100% - 20% = 80%).

Therefore, the sale price is 80% of the original price. If the shoes were on sale for $39.99, we can set up an equation where the original price is represented by x, and the sale price is 80% of x, or 0.80x.

The equation would be 0.80x = $39.99.

To find the original price, we divide both sides by 0.80:

x = $39.99 / 0.80

x = $49.9875

Therefore, the original price of the shoes was $49.99 when rounded to the nearest cent.

Emery bought 3 cans of beans that had a total weight of 2.4 pounds. If each can of beans weighed the same amount, which model correctly illustrates the relationship? Check all that apply

Answers

Answer:

Figure 2 and 3

Step-by-step explanation:

This question is incomplete, please find the figures in the attachment.

Number of cans of beans bought by Emery = 3

Total weight of cans = 2.4 pounds

weight of each can = [tex]\frac{2.4}{3}[/tex] = 0.8 pounds

If x be the number of cans and y represents the total weight then the model for this situation will be

y = 0.8x

Figure 1 :

From this graph weight of each can = [tex]\frac{20}{16}=1.25[/tex] pounds

so this graph is not the correct choice.

Figure 2:

From this graph weight of each can = [tex]\frac{8}{10}[/tex] = 0.8 pounds

So this graph is the correct choice.

Figure 3 :

From the given table, weight of each can = [tex]\frac{4}{5}=0.8[/tex] pounds

So the table shows the relationship.

Figure 4 :

From the given table, weight of each can = [tex]\frac{5}{4}[/tex] = 1.25 pounds

so this table is not the correct choice.

Therefore, figure 2 and 3 is illustrate the relationship.

Write a quadratic function f whose zeros are 6 ad 5

Answers

Final answer:

The quadratic function f whose zeros are 6 and 5 is represented by the formula f(x) = (x - 6)(x - 5). This formula utilizes the fact that the zeros of a quadratic function, also known as the roots, are the x-values for which the function equals zero.

Explanation:

To write a quadratic function f whose zeros are 6 and 5, we first identify the zeros. These zeros are the roots of the equation, meaning the points at which the curve of the function hits the x-axis.

A quadratic function is in the form f(x) = a(x - p)(x - q), where p and q are the zeros. Therefore, if the zeros are 6 and 5, our function becomes f(x) = a(x - 6)(x - 5), with 'a' being any real number. If we take 'a' as 1 (for simplicity), the function becomes f(x) = (x - 6)(x - 5).

So the quadratic function with zeros 6 and 5 is f(x) = (x - 6)(x - 5).

Let 1/x  = a &

1/y = b

So, now the equation:

2a +3b  = 13   --------------------(i)

5a - 4b  = -2  --------------------(ii)

To eliminate a, Multiply equation (i) by 5 and multiply (ii) by (-2)

(i)*5             10a  + 15b = 65

(ii)*(-2)        - 10a + 8b  = 4      ( Now add, a will be eliminated}

b= 69/23

b = 3

Plug in the value of b in equation (i)

2a + 3*3 = 13

2a + 9 = 13

2a  = 13 - 9

2a = 4

a= 4/2

a = 2

earned a total of $22,800. Determine Ben's weekly unemployment compensation.

Answers

Ben's weekly unemployment compensation is $956.15

What is percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.

Now it is given that,

Weekly unemployment compensation = 55%

Ben earned a total in July, August, and September = $22,400

And in October, November, and December = $22,800

Therefore, his total compensation for the six month period = $22,400 + $22,800 = $45,200

his average weekly salary = $45,200 / 26 weeks = $1,738.46

Ben's unemployment compensation = $1,738.46 x 55% = $956.15

Hence,Ben's weekly unemployment compensation is $956.15

To determine Ben's weekly unemployment compensation, we need to calculate the average of his two highest-salaried quarters and then multiply it by 55%.

Therefore, Ben's weekly unemployment compensation is $4,106.67.

Explanation:

To determine Ben's weekly unemployment compensation, we need to calculate the average of his two highest-salaried quarters and then multiply it by 55%. First, let's calculate the average for each quarter:

Next, let's determine the two highest averages:

The highest average: $7,600The second highest average: $7,466.67

Now, we can calculate the weekly unemployment compensation:

The highest average * 55% = $7,600 * 0.55 = $4,180

The second highest average * 55% = $7,466.67 * 0.55 = $4,106.67

Therefore, Ben's weekly unemployment compensation is $4,106.67.

sampling Drink A.

Answers

Answer:

20 out of the 50 participants are assigned to consume Drink A.

However, it is asking us the probability that a participant did NOT consume Drink A, so there are 30 participants that consumed another drink.

The probability is 30/50, or 60%, that a participant did not sample Drink A.

Answer:

3/5

Step-by-step explanation:

of the 50 participants 20 of them will get drink A. This probability is 20/50 which simplified is 2/5. The other 30 participants will get drinks B, C, or D. As a fraction this is equal to 30/50 or 3/5.  Therefore the probability of a participant not sampling drink A is 3/5.
