The distance between two points is √39 One endpoint is (4,−3). It is known that the y-coordinate of the other endpoint is 2.

What is the x-coordinate of this endpoint?

Answers

Answer:

[tex](4-\sqrt{14}, 2)\text{ or } (4+\sqrt{14}, 2)[/tex]

Step-by-step explanation:

We have the two points: (4, -3) and (x, 2).

We know that the distance between them is √39.

To find our x-coordinate of the second point, we can use the distance formula:

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

Let (4, -3) be (x₁, y₁) and let (x, 2) be (x₂, y₂). We also know that the distance d is √39. Substitute:

[tex]\sqrt{39}=\sqrt{(x-4)^2+(2-(-3))^2[/tex]

Solve for x. First, let's square both sides. This cancels out the square roots:

[tex]39=(x-4)^2+(2+3)^2[/tex]

Evaluate the second term on the right:

[tex]39=(x-4)^2+(5)^2[/tex]

Square:

[tex]39=(x-4)^2+25[/tex]

Subtract 25 from both sides:

[tex]14=(x-4)^2[/tex]

Take the square root of both sides. Since we're taking an even root, we need plus/minus. So:

[tex]x-4=\pm\sqrt{14}[/tex]

Add 4 to both sides:

[tex]x=4\pm\sqrt{14}[/tex]

Therefore, there exists two possibilities for our second point. It can either be:

[tex](4-\sqrt{14}, 2)\text{ or } (4+\sqrt{14}, 2)[/tex]

And we're done!

(B) 25

(C) 32

(D) 36

(E) 41

Answers

Answer:

I counted 32 squares in and out

Answer:

A=a^2, so A=4^2=16 , or 4*4=16

Step-by-step explanation:

All sides of a square are equal, so the length of the sides are all 4. Put 4 in for a in the formula A=a^2 or Area = side length squared.

A = 4^2

A = 4 * 4

A = 16

a car rental service charges customers for the number of miles they travel rounded to the nearest whole mile George travels 40.8 miles how many miles will he be charged explain

Answers

Answer:

41 miles

Step-by-step explanation:

the company is saying they will round the number of miles, and charge you that number

when rounding 40.8, you round up to 41

1,2,3,4 rounds down to 0

5,6,7,8,9 rounds up to the next 0 up

The required miles he will be charged for is 41 miles.

Given that,
A car rental service charges customers for the number of miles they travel rounded to the nearest whole mile George travels 40.8 miles
To determine how many miles will he be charged.

What is rounding of values?

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here,
The customer traveled for 40.8 miles,
Now round it to the nearest whole miles, Since 40.8 where 0.8 is 0.2 near to the 1 so the round of 40.8 become 40.8 + 0.2 = 41

Thus, The required miles he will be charged for is 41 miles.

The college tutoring center staff are considering whether the center should increase the number of math workshops they offer to help students improve their performance in math classes. Faculty would like to know if requiring student attendance at these math workshops will improve overall passing rates for their students in their math classes. They plan to use the number of workshops attended to predict the final exam score and regression analysis to determine the effectiveness of the mandatory workshop attendance policy.

For each of the following classify the variable as explanatory, response, or neither.

a. Whether the student attended a workshop.
b. Number of workshops attended
c. Whether the student passes the course

Answers

Answer:

a. Whether the student attended a workshop.   Neither

b. Number of workshops attended.  Explanatory variable

c. Whether the student passes the course. Response variable

Step-by-step explanation:

In a given experiment, the response variable addresses the core of the question that was asked. In the experiment above, we are trying to determine the passing rate. That is the response variable. The explanatory variable provides an explanation for the response.

The number of workshops attended by the students would provide an explanation of their passing rates.  Whether the student attended a workshop is not a consideration in the experiment, because it is believed that they would attend the workshop.

I NEED HELP FAST NO MORE THEN 10 MINUTESTHE MATCH(this is the bolded paragraph)There never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match.Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar.Which line from the bolded paragraph shows the value of the match? but there was a time when men did not know how to kindle fire it was a long, long time before they learned how to kindle one easily There never was a time when the world was without fire In these days we can kindle a fire without any trouble, because we can easily get a match I need help with this question!! the heights of adult males are approximately normally distributed with a mean of 70 inches and a standard deviation of 3 inches. an adult male is categorized as shirt if he is less than 64 inches tall and categorized as tall if he is in the top 2% of adult males in term of height. how tall does an adult make need to be to be assigned to the tall category. x 4 + 5= 8 I need someone to do it and double check for me please.
