2c-4+c= -8+2c

Answer:

If you have the coordinates of two points, you can use the distance formula to find the length of the line segment between them. The distance formula is:

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

where:

And to find a perimeter add all the sides as the perimeter is the sum of all sides of the shape or object.

Perimeter: Sum of all sides

Step-by-step explanation:

Floyd needs 33 matches to make a rectangle with a length of 20 matches.

To find out how many matches Floyd needs to make a rectangle with a length of 20 matches, we can observe a pattern in the given information.

From the given data, we can see that as the length of the rectangle increases by 4 matches, the number of matches used increases by 8. This means that for every additional 4 matches in length, Floyd requires 8 more matches.

Using this pattern, we can calculate the number of matches needed for a rectangle with a length of 20 matches.

First, we need to determine the number of 4-match increments in the length of 20 matches. We can do this by subtracting the starting length of 3 matches from the target length of 20 matches, which gives us 20 - 3 = 17.

Next, we divide the number of 4-match increments by 4 to determine how many times Floyd needs to add 4 matches. In this case, 17 ÷ 4 = 4 with a remainder of 1.

Since Floyd requires 8 matches for each 4-match increment, we multiply the number of increments by 8, which gives us 4 × 8 = 32 matches.

Finally, we add the remaining matches (1 match in this case) to the total, resulting in 32 + 1 = 33 matches needed to reach a length of 20 matches.

Therefore, the height of the tower is approximately 121.4 meters.

No, we can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05. The correct option is a.

Given that:

p-value  = 0.0653                        

Level of significance (p) = 0.05  

The null hypothesis is a typical statical theory that suggests that no statical relationship and significance exists in a set of given single observed variables, between two sets of observed data and measured phenomena.

The null hypothesis is significant because it offers a rough description of the phenomena inferred from the available evidence. It enables researchers to empirically test the relationship statement in a study.

Example: The null hypothesis is that the population density is the same across all states.

The hypothesis is

H0: p=0 vs HA: p \(\neq\) 0

We observe that,

p-value > p (level of significance)

So, fail to reject the null hypothesis (H0).

The correlation coefficient differs from zero when the p-value is less than 0.05.

Therefore, we can not conclude that the correlation coefficient differs from zero.

So you have a circle right. The circle is going to have a center point. The diameter of the circle is the length from a side of the circle to the other side that passes through this center point. The radius is half of the diameter. This means that its basically a line starting at the center point and reaches to one side of the circle. In the picture, the diameter is the red line. The radius is half of that red line.

Explanation

In the question, we are told that Mr. Morales drove 360 miles to a conference. He had transmission problems on the return trip and it took him 3 hours longer at an average speed of 20 mph less than the trip going.

We can break the above information into two equations using the formula for speed.

Recall,

During the first trip we will have

During the second trip we will have;

We can substitute equation i in ii

Since time cannot be negative, t becomes 6 hours. Substituting t=6hours in equation i, we will have;

But since the average speed on the return trip is 20 mph less than the starting speed, the return speed becomes;

Answer: 40 mph

a.The Industry Average Salary is $55,680. b.The Firm A's Average Salary is $51,718.40 .c. Firm B's average salary is approximately 112.27% of Firm A's average salary.

a. To determine the industry average salary, we can use the information that the industry average salary is 96% of Firm B's average salary. Firm B's average salary is $58,000. Therefore, we can calculate the industry average salary as follows:

Industry Average Salary = 96% of Firm B's Average Salary

= 0.96 * $58,000

= $55,680

b. Firm A's average salary is stated as 93% of the industry average salary. To calculate Firm A's average salary, we can multiply the industry average salary by 93%:

Firm A's Average Salary = 93% of Industry Average Salary

= 0.93 * $55,680

= $51,718.40

c. To express Firm B's average salary as a percentage of Firm A's average salary, we can divide Firm B's average salary by Firm A's average salary and multiply by 100:

Percentage = (Firm B's Average Salary / Firm A's Average Salary) * 100

= ($58,000 / $51,718.40) * 100

≈ 112.27%

The coordinates of the point on the unit circle at angle 225° are \(\bold{(-\frac{\sqrt{2} }{2}, -\frac{\sqrt{2} }{2})}\)

The coordinates of the points of the circle x² + y² = r² are \((r~cos\theta, r~sin\theta)\)

"It is a circle with radius 1."

For given example,

We have been given an angle of 225°

⇒ \(\theta\) = 225°

We need to find the coordinates of the point on the unit circle at an angle 225°.

Here, r = 1

So, the first coordinate would be,

\(r~cos\theta=(1)~cos(225^{\circ})\\\\\Rightarrow r~cos(225^{\circ})=cos(270^{\circ} - 45^{\circ})\\\\\Rightarrow r~cos(225^{\circ})t=cos(270^{\circ}) cos(45^{\circ})+sin(270^{\circ}) sin(45^{\circ})\\\\\Rightarrow r~cos(225^{\circ})=0+(-1)(\frac{1}{\sqrt{2} } )\\\\\Rightarrow r~cos(225^{\circ})=\bold{\frac{-1}{\sqrt{2} }}\\\\\Rightarrow r~cos(225^{\circ})=\bold{-\frac{\sqrt{2} }{2} }\)

Now we find the second coordinate of the point.

\(r~sin\theta=(1)~sin(225^{\circ})\\\\\Rightarrow r~sin(225^{\circ})=sin(270^{\circ} - 45^{\circ})\\\\\Rightarrow r~sin(225^{\circ})=sin(270^{\circ}) cos(45^{\circ})-cos(270^{\circ}) sin(45^{\circ})\\\\\Rightarrow r~sin(225^{\circ})=(-1)(\frac{1}{\sqrt{2} } )-0\\\\\Rightarrow r~sin(225^{\circ})=\bold{\frac{-1}{\sqrt{2} }}\\\\\Rightarrow r~sin(225^{\circ})=\bold{-\frac{\sqrt{2} }{2} }\)

Therefore, the coordinates of the point on the unit circle are \((-\frac{\sqrt{2} }{2}, -\frac{\sqrt{2} }{2})\)

Step-by-step explanation:

the inside expression of an absolute value expression can be positive or negative, but the result is only the positive one.

therefore, for our example here the negative case would be

2.5x - 6.8 = -12.9

which gives us

2.5x = -6.1

x = -6.1/2.5 = -2.44

and the positive case would be

2.5x - 6.8 = 12.9

and that gives us

2.5x = 19.7

x = 19.7/2.5 = 7.88
