B) longitudinal dunes
C)till
D)barchan dunes

Answer 1

@tylermcmullen23

Answer 2

which 2 do you KNOW that CAN be deposited by wind??

Answer 3

the dunes

Answer 4

well, i know that A can be deposited by wind. its an accumulation caused by wind depositation.. what the heck is a till?? lol

Answer 5

couldn't tell ya lol

Answer 6

oh lord lol. hold on ill find out lol

Answer 7

haha okay

Answer 8

I think it's longitudinal waves maybe idk lol

Answer 9

no. what i found is that tills are deposited directly from glacial ice

Answer 10

so itd be till because its deposited from glacial ice, not wind

Answer 11

okay thank you!!

Answer 12

anytime! :)

Answer 13

I have 1 more!

Answer 14

okie dokie

Answer 15

oops idk what just happened

Answer 16

lol

Answer 17

Why are desert landscapes jagged and rocky?
The evaporation process creates angular surfaces.
Lack of vegetation causes sinkholes between rock formations.
There is little chemical weathering to round the landscape

Answer 18

sinkholes are caused by some sort of collapse in the earth layers, not lack of vegetation, so b is incorrect. and evaporation wouldnt cause angular surfaces, bc it just makes the surface dry. so id say C

Answer 19

thanks:)

Answer 20

welcome :)

Answer 21

Let f(x) = -4x + 7 and g(x) = 2x - 6. Find (g o f) (1)
A) 0
B) 3
C) 23
D)–4

Answer 22

composition of functions??? is that what its called?

Answer 23

I think so yes

Answer 24

not too bad.. i think i know this

Answer 25

sweet!!

Answer 26

im not 100% sure but try 23

Answer 27

kk thanks! its a little test so it wont tell me if I am right or not until the end

Answer 28

If the parent function is the square root of x, describe the translation of the function square root of x-1.

One unit up from square root of x
One unit to the right of square root of x
One unit to the left of square root of x
One unit down from square root of x

Answer 29

since its x, it cant be down or up, bc that would be y. in order for it to be to the left, it would have to be sqrt(x+1) but since its sqrt(x-1), you would be to the right

Answer 30

so i believe its B

Answer 31

okay thank you:)

Answer 32

youre welcome! anymore?

Answer 33

How is the graph of y=square root of x=3 translated from the graph of y=square root of x

shifted 3 units left
shifted 3 units up
shifted 3 units down
shifted 3 units right

Answer 34

is that"=" supposed to be a +??? or no?

Answer 35

no they are equal signs

Answer 36

oh ok

Answer 37

well, since it want "y=", it cant be moved left or right. so itd have to be between B and C.

Answer 38

im not for sure on this one as far as up or down.. but i believe it is 3 units up

Answer 39

What is the domain and range for the following function and its inverse?
f(x)=3x-1/2

Answer 40

options or no?

Answer 41

yes but they are so long to type out lol

Answer 42

domain: \[-\infty<x<\infty\]
range: \[-\infty<f(x)<\infty\]
inverse: \[\frac{ 2x+1 }{6}\]
if those are options put together, idk

Answer 43

a) f(x)=domain: all real numbers, range: all real numbers
f^-1=domain: all real numbers, range: all real numbers

b) f(x)=domain: x<0 range:y>-1

c) f(x) domain:x>0, range: y>0

d) f(x) domain: x>0, range: y<-1
domain: x<-1 range:y>0

Answer 44

itd have to be A, because the domain and range that i got were both the same, which is \[\infty\] also known as all real numbers so.. i guess itd be a

Answer 45

Let f(x) = -2x - 7 and g(x) = -4x + 6. Find (f o g) (-5)
3
–59
26
–6

Answer 46

well, the result of it is 8x-19. so plug in -5, whichmakes the equation now 8(-5)-19. 8*-5=-40. -40-19=-59

Answer 47

u da bomb

Answer 48

doubt it lol

Answer 49

rewrite y=the square root of 9x+45-2 to make it easy to graph using a translation. Describe the graph.

Answer 50

yeahh.. about that one.. lol idk does it look like \[y=\sqrt{(9x+45)-2}\] or \[y=\sqrt{9x+45-2} \]

Answer 51

the options are like \[y=3\sqrt{x+5}-2\]

Answer 52

im sorry meg, i dont know this one :(

Answer 53

just pick c. its almost always right lol

Answer 54

What is the domain and range for the following function and its inverse?

f(x) = x2 – 2

Answer 55

thast supposed to be x^2

Answer 56

domain: all real numbers
range: \[y \ge-2\]

Answer 57

I hate math so much

Answer 58

i do too. are those an option for one?

Answer 59

Rewrite y = \[\sqrt{25x-75}\] + 3 to make it easy to graph using a translation. Describe the graph.

Answer 60

ill try. because i think youre supposed to just simplify it. so ill try ok?

Answer 61

okay!

Answer 62

is this an option? \[5*\sqrt{x-3+3}\]

Answer 63

yes but you have to say which way it translates too

Answer 64

im not sure where it translates to
