Answer 4

the degree of root is 3. so x doesn't have to be positive.

Answer 5

I would say yes to C for the second

and although, I don't know how to do this stuff

Answer 6

http://www.wolframalpha.com/
is pretty reliable, so yeah, B for the first...

Answer 7

parent form is: y = √x
vertex form for it is: y = √(x-h) + k
when (h, k) is the vertex

Answer 8

so when y = √(x - 1) + 1
^ ^ so vertex is (1, 1)

Answer 9

yep! :)

Answer 10

[ <-- bracket means including (or closed hole)
( <-- parentheses means excluding (or open hole)

Answer 11

and the furthest left you can go is 2 so...

Answer 12

Option C then since it has 2?

Answer 13

yep :)

Answer 14

aww... sorry :/
... (problem was that I had failed Algebra II class...)
I mean, I can still try to help and all, but it's getting to the point where you're learning stuff that I hadn't cared to learn ;)

Answer 15

yeah, okay :)
when in doubt: http://www.wolframalpha.com/

Answer 16

Haha :) Is that website always correct? I'm curious.

Answer 17

It's like a math google ;)
you know how some people use the analogy "You can't compare apples and oranges" http://www.wolframalpha.com/input/?i=compare+apples+and+oranges

Answer 18

yeah, I understand :)

Answer 19

63 = 9 * 7
y = y^2 * y
√63y^3 = √(9y^2)(7y) = 3y√7y

Answer 20

So b?

Answer 21

yep :)

Answer 22

√28 = √4*7 = 2√7
√63 = √9*7 = 3√7
3(2√7) + 2(3√7) = 6√7 + 6√7 = 12√7

Answer 23

yep :P
but do ya see how I'm getting these numbers? ;)

Answer 24

foil >,<
(√2 * √2) - (√2 * √7) - (3√5 * √2) + (3√5 * √7)

Answer 25

my way: two middle signs are minuses
therefore last expression should be + because - * - = +
so A

Answer 26

I'm 99% sure that this is C.

Answer 27

yeah ;)

Answer 28

the denominator is what comes out in front
like x^(1/2) = ^2√x^1
so (2m)^5/3 = ^3√2^5 m^5
2^5 = 32
so B

Answer 29

Actually for the first one I think it's D not C.

Answer 30

then correct for both ;)

Answer 31

idk this one...

Answer 32

I feel like it might be D because I don't see how it'd have a solution but I have no idea.

Answer 33

I suppose you can guess D...
wolframalpha is confused too...

Answer 34

all correct! :D

Answer 35

okay :)

Answer 36

that's alright :)
I'm having dinner soon tho...

Answer 37

Oh. What time is it where you are? It's only 1:51pm here. You can have dinner first if you'd like. I don't want you to wait and be hungry haha.

Answer 38

It's 4:53pm over here :P
my family usually has dinner 5pm-6pm

Answer 39

Oh I see. Well you should probably have dinner with your family first and whenever you're available afterwards, we can start on these Algebra 1 questions. I'm not really in a hurry for these.

Answer 40

okay, thanks :)
I'll be back in less than an hour... more like 25min :P

Answer 41

Take your time! :D Enjoy your family dinner!

Answer 42

I'm back! :D

Answer 43

Some science students drop and object from various heights and record the time it takes for the object to reach the ground. which is the independent variable in this situtation?

A. height
B. type of object
C. time
D. number of objects

Answer 44

height is dependent on the time
time increase at a constant rate, therefore is the independent variable...
I'm pretty sure..

Answer 45

Mrs. Pierce is taking pictures at a family reunion. The table shows the amount of memory space available in her digital camera. Which is the independent quantity?

Number of Pictures Taken: 10, 20, 30, 40, 50
Memory (MB): 241, 233, 222, 210, 201

Answer 46

the number of pictures affects the amount of memory...
so Number of Pictures = independent

Answer 47

Maybe the balance?

Answer 48

yep :)

Answer 49

sorry one moment I'm doing a lot of these myself and getting them right

Answer 50

good job :) I'm proud of you :D

Answer 51

haha yay thanks! I'm proud of myself and afterall these are really easy. It'll be a little longer sorry

Answer 52

It's fine ;) I don't mind :P

Answer 53

I feel like it's A more though.

Answer 54

A would be correct :)
because the number of bottles is Dependent on the number of hours

Answer 55

C. number of bottles filled

Answer 56

number of books is dependent on amount of time

Answer 57

distance is dependent on speed

Answer 58

bottles filled is dependent on time
(when in doubt "time" is almost always independent)

Answer 59

oh okay thank you for your help today. I'm actually in the process of moving house and I'm kinda just sitting here on my computer doing this work whilst everyone else its watching me and moving things in the truck. I think I'll go help so we can both take a break from this. Thank you very much for your time and effort today! :) Talk to you tomorrow.

Answer 60

yeah, you're welcome :)
I most likely won't be on for very long tomorrow though...
Have a nice day, and hope you like your new house! :D

Answer 61

Thanks! It's okay, as long as your available throughout or at least later this week. We got through most of the things I needed to complete already so I'm greatful for that. Have a good rest of your day :)
