Answer:
the answer is 9 :)
Step-by-step explanation:
Answer: 270
Step-by-step explanation:
I might be wrong on this one, but the average license plate is 12 in by 6 in. One meter is around 3 feet. The dimensions of the wall are 9 feet by 15 feet.
Length wise, 15 license plates can fit on the wall, and bright wise, 18 can fit on the wall.
15 times 18 = 270
270 license plates is your answer
A ) cos² x · 1 / sin x - 1 / sin x = - sin x
cos² x - 1 / sin x = - sin x
- sin² x / sin x = - sin x
- sin x = - sin x ( correct )
B ) sin x ( cos x / sin x + sin x / cos x ) = 1 / cos x
sin x · ( cos² x + sin²x ) / sin x cos x = 1 / cos x
sin x · 1 / sin x cos x = 1 / cos x
1 / cos x = 1 / cos x ( correct )
C ) cos² x - sin² x = 1 - 2 sin² x
1 - sin² x - sin² x = 1 - 2 sin² x
1 - 2 sin² x = 1 - 2 sin² x ( correct )
D ) 1/sin²x + 1/ cos²x = 1
cos²x + sin² x / sin² x cos² x = 1
1 / cos² x sin² x = 1
cos²x sin² x ≠ 1
Answer: D ) is not an identity.
Answer:
The answer is 28
Step-by-step explanation:
is a valid argument
is not a valid argument
For the first argument:
From the definition of absolute value function
if 
That is every positive number is its own absolute value. Since
,
we can argue that
so the first argument is valid
For the second argument:
From the definition of absolute value function
This means that
or
no part of the definition allow for the option 
. So the second argument is not valid.
