4/5 is already simplified so its going to be 4/5 or .45
Answer:
104.607kph
Step-by-step explanation:
Conversion from mph to kph = 1.609mph
Step-by-step explanation:
Given
f(x) = 12x + 2
f^-1(x) = ?
Now
Let y = f(x)
or y = 12x + 2
Interchanging the role of x and y
x = 12y + 2
x - 2 = 12y
y = <u>x </u><u>-</u><u> </u><u>2</u>
12
Therefore f^-1(x) = <u>x </u><u>-</u><u> </u><u>2</u>
12
Hope it will help you.
The answer is 17/80
Step by step:
Move decimal 2 to the left,
.2125
Then:
2125
____
10000
Then just simplify from there

it just so happen that √2 is an irrational number, so any product with it as a factor, will yield an irrational number as well.
factoid: Ancient Greeks were scared of irrational numbers, and they steered clear from √2.
