Step-by-step explanation:
To find : Which of the following is an irrational number?
Solution :
Irrational number is defined as number which cannot be written in the form is p/q where p and q are integers and q is non-zero.
Irrational number is non-repeating and non-terminating.
A)
The value of pi is
The number is non-terminating and non-repeating.
So, is an irrational number.
B)
The number is written in p/q form so it is rational number.
C)
The number is written in p/q form so it is rational number.
D) 18

Answer:
Step-by-step explanation:
given D : (7,-3), and D' : (2,5)
the coordinates of D can be represented as (x1,y1), and the coordinates of D' can be represented as (x,y).
you can simply take the difference in the x values and difference in the y values from the preimage to image.
like this:
f'(x,y) → f(x+(x-x1),y+(y-y1)) :
D'(x,y) → D(x+(2-7),y+(5--3))
D'(x,y) → D(x<u>-5</u>,y<u>+8</u>) :
