Examine the graph.

The graph looks like one of square-root....let's see.


If we make a translation of (-3,-2), i.e. the beginning of the graph, to the origin, we will see that we have the following points on the graph,

(0,0), (1,1), (4,2), (5,2.2), (8,2.8)

all of which correspond to the sqrt(x) function.


Thus if we take the parent graph as sqrt(x), and translate to the current position by a translation of (-3,-2), we get the current graph.


To do the translation, we recall that a translation of a parent function f(x) by (h,k) can be effected by

g(x) ->f(x-h)+k


Setting h=-3, k=-2, and f(x)=sqrt(x), we get

current graph g(x)=f(x-(-3)+(-2)=f(x+3)-2 = sqrt(x+3)-2

kirill [66]

Answer:

n=12

I don’t know the answer to that one can you help me please
dybincka [34]

Answer:

16/45

Step-by-step explanation:

Step 1:  When dividing fractions, use “KFC”.  It means Keep the first fraction, Flip the second one, and  

              Change it to multiplication

-4/20 ÷ -9/16    →    -4/20 ∙ 16/-9

Step 2:  Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end.  It’s easier arithmetic to reduce at this step.  The first fraction reduces because both the numerator and denominator are divisible by 4.  

-1/5  ∙   16/-9    

Step 3:  Multiply numerators and denominators together to get one fraction

(-16)/(-45)  

Step 4:  Cancel out the negatives, a negative divided by a negative is a positive.  Our final answer is

 

16/45

Fraz is running a science fair experiment where mice run through a maze with 4 turns. At each turn, the mouse can take a right o
kherson [118]

Answer:

the probability is 0.125

Step-by-step explanation:

The number of ways in which the mouse can move in the 4 turns is calculated using the rule of multiplication as:

<u>       2           </u>* <u>            2            </u> * <u>             2             </u>* <u>         2           </u> = 16

  1st turn              2nd turn               3rd turn               4th turn

Because the mouse can take two options at every turn, right or left.

Now, from the 16 possibilities of movements, a mouse will find an exit in just two options:

1. right-right-left-left

2. left-right-right-left

So, the probability that a mouse will find an exit is:

P=\frac{2}{16}=0.125

Because, there are 16 possibilities and a mouse will find an exit using 2 of them.
