Answer:
Since we know that,
cos2x= cos²x-sin²x=(cosx-sinx)(cosx+sinx)
And, sin2x=2sinx.cosx
Therefore,
1-sin2x= cos²x+sin²x-2sinx.cosx
1-sin2x= (cosx-sinx)²
Then let
y=cos2x/(1-sin2x)

Answer: Even
Step-by-step explanation:
The given product is
When we solve the given product we get,
Now, 54 is not a prime number since it has more than two factors such as 2 and 27.
[ ∵ A prime number is a whole number greater than 1 and it has only two factors which are 1 and itself. ]
It is even not odd since its last digit is an even number.
54 cannot be written as , for any natural number n, therefore, it is not a perfect square.
Answer: Hello mate!
Let's analyze the options:
A) prime, a prime number is a number that only can be divided by 1 and itself, if you look at the number 2*27, you can see that this number can be divided by 2 and 27, then this number is not prime.
B) An odd number has the form m= 2*n + 1 where n is an integer number.
in this case, we have 2*27, so this number is not odd.
C) perfect square, 2*27 = 54, we know that 7*7 = 49, and 8*8 = 65
so 2*27 lays in between two consecutive perfect squares, so 2*27 can not be a perfect square.
D) an even number has the form 2*n, where n is an integer.
n = 27 is this case, so 2*27 = 54 is an even number.

Step-by-step explanation:
Let x represent the total number of red and blue beads
Angie has some red and blue beads. 40% of her beads were red. This means that the total number of red beads is
40/100 × x = 0.4x
The number of blue beads would be
x - 0.4x = 0.6x
When she lost 50 blue beads, the number of blue beads was reduced by 1/3 its original number of beads. This means that
0.6x - 50 = 0.6x - 0.6x/3
0.6x - 50 = 0.6x - 0.2x = 0.4x
0.6x - 0.4x = 50
0.2x = 50
x = 50/0.2 = 250
The number of blue beads that Angie had initially is
0.6 × 250 = 150
The number of blue beads that Angie has left is
150 - 50 = 100 beads
The number of beads that Angie has in the end is
250 - 50 = 200 beads
