Answer:
80 degrees
Step-by-step explanation:
Since we know that a straight line is 180 degrees and 100 degrees and x lie on the same line:
100 + x = 180
x = 80
Hope this helps :)
Answer:
f(x) = (x - 2)²
Step-by-step explanation:
f(x) = x² - 4x + 4 is a perfect trinomial.
You know a trinomial is perfect when double the square root of the first term multiplied by the square root of the last term equals the middle term.
As an equation, a trinomial in the form ax² + bx + c = 0:
2√a√c = b is a perfect trinomial.
Perfect trinomial are factored in this form:
(√a ± √c )(√a ± √c ) = (√a ± √c )²
Whether the sign is + or - depends on if the middle term is positive or negative.
In f(x) = x²-4x+4, the middle term is a negative.
The square root of the first term is 1.
The square root of the second term is 2.
The factored form is (x - 2)²

Answer:
Option C is correct
Conversion factor is used : 60 seconds / 1 minutes
Step-by-step explanation:
Given: Speed = 20.1 meters per second
To convert this speed in meters per minute.
Conversion Factor is the relationships between units to convert from one unit to another unit.
Use conversion: 1 minute= 60 second
speed = 
Now, multiply the speed in meter/seconds with 60 seconds and you will get the speed in meters/minute.
i.e,
speed = 
Therefore, the conversion factor is used : 60 seconds / 1 minutes
