Find the distance between the points A(13,2) and B(7,10)

Anna007 [38]

Answer:

$10 = D$

Step-by-step explanation:

Method #1

We can draw a right triangle on the graph upon where the points are located and use the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

${6}^{2} + {8}^{2} = {c}^{2}$

$36 + 64 = {c}^{2}$

$100 = {c}^{2}$

$10 = c$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

_______________________________________________

Method #2

Or, we can use the Distance Formula:

$\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D$

B[7, 10] A[13, 2]

$\sqrt{[-2 + 10]^{2} + [-13 + 7]^{2}} = D$

$\sqrt{8^{2} + [-6]^{2}} = D$

$\sqrt{64 + 36} = D$

$\sqrt{100} = D$

$10 = D$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

** You see? It does not matter which method you choose, as long as you are doing the work correctly.

Find all the factors of 38,39 and 40 do they have any factors in common explain how you can tell if some numbers have factors in

zvonat [6]

Answer:

38= 1, 2, 19 and 38

39= 1,3, 13 and 39

40= 1,2,4,5,8,10,20 and 40

common factors is 1

to know the factors in commas without finding the factor is to simply divide the number by each factor gotten, take for example i have 38 as the number and i have gotten 1, 2.

38 divided by 1 equals 38

38 divided by 2 equals 19

so they are the factors

0.194 if 94 is repeating how do I write it as a fraction?

umka2103 [35]

If you divide a number by 9 then that number is repeated (1/9 = 0.111111... or 2/9 = 0.22222....)

So if we want 94 to repeat in the decimal 0.194 then we can have 94/99. But the thing is that we don't have 94 being repeated starting from the tenths place so we can possibly do 94/990.

Now we do have a tenths with a zero but we need a one to replace that zero. To do that we have to add 1/10 + 94/990 = 99/990 + 94/990 = 193/990.

Christina went to the salon and had 5/8 of an inch of hair cut off. The next day she went back and asked for another 5/8 of an i

Ugo [173]

Here you'll want to add 5/8 with 5/8. Since they have the same denominator already then 5/8+5/8 = 10/8. Simplifying that down to 5/4 then changing to a mixed number is 1 1/4 inches.
