Answer:
cos(2x) = 1 - 2sin²(x)
cos(2x) = 2cos²(x) - 1
1/cos(x) = sec(x)
1) (1-cos(2x))/cos(x) = 2sec(x)sin²(x)
Starting from LHS
(1- (1 - 2sin²(x))/cos(x)
2sin²(x)/cos(x)
2sec(x)sin²(x) = RHS
2) 1/sec²(x) = 1 + cos(2x) - cos²(x)
Starting form RHS
1 + 2cos²(x) - 1 - cos²x
cos²x
(1/sec(x))²
1/sec²(x) = LHS

Answer:
Numerator = 5
Step-by-step explanation:
A fraction is in the form of 
.
x is numerator of the fraction and y is the denominator.
The given fraction is 
.
Here,
5 is the numerator and 8 is the denominator.
Hence, in the given fraction, 5 is the numerator and 8 denotes the denominator.
Jenna has a bag that contains the following
=> 7 red marbles
=> 25 blue marbles.
She selects a marble at random, and then, without replacing the first one, selects <span>another marble at random.
=> 7 + 25 = 32 marbles are there in all.
For blue marble
=> 1/32 is the probability
For red
=> 1/31 is the probability
or
3%</span>
