Question

help i have 4 questions

Answer 1

What is the approximate distance between the points (4, 5, 4) and (3, 7, 6)?
8

9

17<<<<<<<i think this is the answer.

29

Answer 2

subtract, square, add, and sqrt is the process

Answer 3

(4, 5, 4)
-(3, 7, 6)
----------
1 2 2
1+4+4 = 9

sqrt(9) = 3

hmm, thats not an option tho

Answer 4

9 is

Answer 5

make sure youre information is correctly posted

Answer 6

yesp these are the choices

8

9

17

29

Answer 7

http://www.wolframalpha.com/input/?i=distance+between+%284%2C+5%2C+4%29+and+%283%2C+7%2C+6%29

distance, as is, is 3

Answer 8

wait oops its -4,5, 4 and 3,-7,-6

Answer 9

oops im so sorry :(

Answer 10

:) same process, different values

Answer 11

-4,5, 4
-3,7,6
----------
7 12 10
49+144+100= 293

sqrt(293) is greater then 10, 11, 12, 13, 15, 17 is looking plausible yes

Answer 12

so i was right 17?

Answer 13

29^2 = 4xx
15^2 = 225

sqrt(293) = 17.11.... so yes

Answer 14

cool okay here is the next one

Answer 15

When the point (-1, 3) is dilated with the center of dilation at the origin, the image of the point is (-4, 12). What is the scale factor of this dilation?

4

0.25

- 4

-0.25

Answer 16

-1 * s = -4
3 * s = 12

solve for s

Answer 17

i get that part but i get confused when solving for s my original answer was 0.25 but i think im wrong b/c im unsure how to do it :(

Answer 18

3, times what, equals 12? you have to know your basic times tables at least :)

Answer 19

4 lol

Answer 20

then the scale factor has to be 4 :)

Answer 21

lol wow i was way way off lol thank you for your help on that one :P

Answer 22

lol, thats ok, my first guess would have been 132

Answer 23

lol
^.^ well the next two have pic that go with them .

Answer 24

we gots a draw button underneath, or if you can do a screenshot and attach as a jpg thats fine

Answer 25

Find the measure of APB if the measure of arc AB = 130°.



100°
70°
65°
50°

Answer 26

theres a thrm that goes; the angle on the outside of what we are looking at is the difference between the outer arc and the inner arc

Answer 27

lol thats a long term to remember haha :P

Answer 28

they give the inner are as 130

the outter arc is 360 - 130

(360 - 130) - 130 should do it

Answer 29

100 ^.^

Answer 30

100 seems to work for me

Answer 31

we can dbl chk another way tho

Answer 32

the central angle is equal to the inner arc: 130
the tangents are always 90; so another 180

Answer 33

i guess i forgot the divide by 2 part of the thrm :/

Answer 34

(outer-inner)
-----------
2

Answer 35

Which pair of triangles is similar?

Answer 36

okay sorry about that

Answer 37

similar triangle have a common ratio of parts

Answer 38

i thought it was number 1

Answer 39

spose your lengths are: a,b,c and A,B,C

a b c
-- = -- = --
A B C

Answer 40

ok

Answer 41

number 1 is good

Answer 42

but so is number 4 lol

Answer 43

3 4 5 : 1
9 12 15 : 3

Answer 44

number 4 is not

Answer 45

3 4 5
-- = --- not= ----
9 12 16

Answer 46

really? i guess thats why i was confused i was stuck between the two

Answer 47

helps if i use the right ratios .... #4 is squares

Answer 48

3^2 = 9
4^2 = 16
5^2 = 25

these are not common rations\[\frac{5}{25}=\frac15\]
\[\frac{4}{16}=\frac14\]
\[\frac{3}{9}=\frac13\]

Answer 49

oh i see and we found out that number 1 was 1/3 so the answer is number 1 ???

Answer 50

correct

Answer 51

thank you so much
^.^

Answer 52

youre welcome, and good luck :)
