Answer:

Step-by-step explanation:

The answer is A because...

Step one wen need to multiply the conjugate. So we should have 2 square root of 3 square root of 5/ 3 square root of 5 square root of 5
Step two-Then we solve the numerator. 2 square root 3 square root 5= 2 square root 15
Step three- Now we solve the denominator 3 square root 5 square root 5 which equals 15
Finally we place the numerator over the denominator to get 2 square root
It will be easier to understand if you see it in picture so I typed it up for you
Hope this helped

Write functions for each of the following transformations using function notation. Choose a different letter to represent each f

kupik [55]

Answer:

$(a)\ T_{a,b} =(x +a,y+b)$

$(b)\ F_{y\ axis} = (-x,y)$

$(c)\ F_{x\ axis} = (x,-y)$

$(d)\ R_{o,90^o} = (-y,x)$

$(e)\ R_{o,180^o} = (-x,-y)$

$(f)\ R_{o,270^o} = (y,-x)$

Step-by-step explanation:

Solving (a): Translate a units right, b units up

When a function is translated a units right, the number of units will be added to the x coordinate

When a function is translated b units up, the number of units will be added to the y coordinate.

So, we have:

$T_{a,b} =(x +a,y+b)$

Solving (b): Reflect across y-axis

When a function is translated across the y-axis, the x coordinate gets negated.

So, we have:

$F_{y\ axis} = (-x,y)$

Solving (c): Reflect across x-axis

When a function is translated across the x-axis, the y coordinate gets negated.

So, we have:

$F_{x\ axis} = (x,-y)$

Solving (d): 90 degrees rotation counterclockwise

When a function is rotated 90 degrees counterclockwise, the y-coordinates gets negated and then swapped with the x-coordinate.

So, we have:

$R_{o,90^o} = (-y,x)$

Solving (e): 180 degrees rotation counterclockwise

When a function is rotated 180 degrees counterclockwise, the coordinates are negated.

So, we have:

$R_{o,180^o} = (-x,-y)$

Solving (f): 270 degrees rotation counterclockwise

When a function is rotated 270 degrees counterclockwise, the x-coordinates gets negated and then swapped with the y-coordinate.

So, we have:

$R_{o,270^o} = (y,-x)$

A store advertises 15% off an item that regularly sells $300.what is the sale price off the item?

Komok [63]

The original price of the item is said to be 100 dollars.
Now, it offers 15% discount. Let's solve for the dicounted price.
=> 15% = 0.15
Solution:
=> 300 * .15
=> 45 dollars
=> 300 dollars - 45
=> 255 dollars
