Answer: [tex]\sqrt{41}[/tex]
On a keyboard you would type sqrt(41)
===========================================
Work Shown:
[tex]\text{point L} = (x_1, y_1) = (2,-1)\\\\\text{point N} = (x_2, y_2) = (7,-5)\\\\[/tex]
[tex]d = \text{distance from L to N}\\\\d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2 } \ \text{ ... distance formula}\\\\d = \sqrt{ (2-7)^2 + (-1-(-5))^2 }\\\\d = \sqrt{ (2-7)^2 + (-1+5)^2 }\\\\d = \sqrt{ (-5)^2 + (4)^2 }\\\\d = \sqrt{ 25 + 16 }\\\\d = \sqrt{ 41 }\\\\[/tex]
----------
A slight alternative is to plot the point M(2,-5) to form right triangle LMN. The 90 degree angle is at point M.
The legs are of length LM = 4 and MN = 5, which are found by subtracting the x coordinates together and the y coordinates together (or you can count the spaces). From there, use the Pythagorean theorem to get the hypotenuse LN.
The distance formula is an altered version of the Pythagorean theorem.
Answer:
The distance between the two points provided is: [tex]\sqrt{41}[/tex]
Step-by-step explanation:
First thing is to evaluate what the distance formula is:
d = [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }[/tex]
Then substitute the points provided:
d = [tex]\sqrt{(7-2)^{2}+(-5-(-1)^{2} }[/tex]
(The double negative between -5 and -1 will make the -1 a positive 1). (1)
d = [tex]\sqrt{(5)^{2}+(6)^{2} }[/tex]
Now the exponents:
d = [tex]\sqrt{25+36}[/tex]
Second to last, you must add:
d = [tex]\sqrt{41}[/tex]
If needed ± should be added in front of the radical.
The points are the same as the ones that were given.

Find the square root of the

(iii) 3136
Answers
1568 = 784 x 2
784 = 392 x 2
392 = 196 x 2
196 = 98 x 2
98 = 49 x 2
So 49 x 2 x 2 x 2 x 2 x 2 x 2 = 49 x 4 x 4 x 4 = 3136
So the square root of 3136 = the square root of (49 x 4 x 4 x 4) = 7 x 2 x 2 x 2 = 56

How does the side length of the square relate to the square root?
Answers
Answer:
The sides can be found by taking the square root of the area. , where = side.
Step-by-step explanation:
Answer:
the area of any quadrilateral can be determined by multiplying the length of its Base by its height. since we know the shape here is square we know that all sides are of equal length. from this we can work backwards by taking the square root of the area to find the length of one side.

The sum of the first 44 positive odd numbers is

Step-by-step explanation:
The sum of the first n odd numbers is n^2
This can be proven, but for 5 odd numbers, 1,3,5,7,9, the sum should be 5^2, or 25, which it is
So for the first 44 odd numbers, the sum is n^2=44^2=1936

Slope problem im pretty sure it is -1/3 correct me if im wrong
Answers
The answer is -3.
Explanation:
The slope of a line is the ratio of how many units the line moves up or down the y axis to how many units the line moves across the x axis. In other words, it’s the rise/run of a line.
In the graph in the attached picture, every time the x axis increases by one, the y axis decreases by 3. Therefore, the ratio would be -3/1.
-3/1 is equal to -3, making the slope of this line -3.

Mr. and Mrs. Wagner are getting ready to drive across the USA from Philadelphia, PA to Los Angeles, CA in five days. The distance is approximately 3,000 miles. The average price of gasoline is about $2.10 per gallon. They plan to stay in a hotel for four nights and budget the cost of meals be about $45 per day per person.
Answers
Answer:
(a) $ 84.
Step-by-step explanation:
Given that, the distance between the PA to CA = 3000 miles.
Time of travel, t = 5 days.
The average price of gasoline, r = $ 2.10/ gallon
Cost of meal for one person, c = $ 45/ day
Total number of persons, n = 2 (Mr. and Mrs. Wagner)
(a) The average of van = 75 mpg.
So, to cover 75 miles, the amount of gasoline required = 1 gallon
By using the elementary method, the amount of gasoline required to cover 1 mile = 1/75 gallons.
So, the amount of gasoline required to cover 3000 miles
= (1/75)x 3000= 40 gallons.
Now, cost for gasoline = 40 x 2.10=$84
Hence, the total cost of the gas for the trip is $84.

10 POINTS PLEASE HELP ASAP!!! What is the length of the altitude of the equilateral triangle below?
Answers
Step-by-step explanation:
Hey there!
Looking on figure we find that triangle ABC is a Right angled triangle.
Taking reference angle as C, we get;
Perpendicular (p) = a
Base(b) = 5
And hypotenuse (h)= 10
Now;
Using Pythagoras relation, we get;
[tex]p = \sqrt{ {h}^{2} - {b}^{2} } [/tex]
Put all values.
[tex]a = \sqrt{ {10}^{2} - {5}^{2} } [/tex]
[tex]a = \sqrt{100 - 25} [/tex]
[tex]a = \sqrt{75} [/tex]
[tex]a = 5 \sqrt{3} [/tex]
Therefore, answer is Option E.

Which of the following tables represents the rule, y equals seven less than four times a number?
Answers
Answer:
the second table.
Step-by-step explanation:
I used process of elimination to determine which one fits.
here's how I know I'm correct:the rule is, y = 4x - 7
if you put in the numbers from table 2
-3 = 4(1) - 7
-3 = 4-7
-3 = -3
13 = 4(5) - 7
13 = 20 - 7
13 = 13
