Answer: Part A 11520 for the blue one
Part B for the orange one is 12
Step-by-step explanation:
Multiply them all by each other
<span>cos 4x + cos 2x = 2 - 2 sin^2 2x - 2 sin^2 x
cos 4x + cos 2x = 1 + 1 − 2sin^2(2x) − 2sin^2(x)
cos 4x + cos 2x = (1 - 2sin^2(2x)) + (1 - 2 sin^2(x)
cos 4x + cos 2x = cos 4x + cos 2x</span>
Answer:
Step-by-step explanation:
Answer:
8 potential winners ( 444, 446, 644, 464, 466, 646, 664, 666)
Step-by-step explanation:
To alter the odds the balls numbered 4 and 6 werent injected with liquid and hence they will float making it certain for their selection and determination as the winning digits. The potential of the winning numbers are (2)^3=8.
Since 4 and 6 ain't filled with liquid, they would be selected and determine the digits in the winning numbers in 8 ways ( 444, 446, 644, 464, 466, 646, 664, 666). The potential winning number is among them.
For the reciprocal, you swap numerator and denominator.
a. The reciprocal of
is
To rationalize the irrational denominator, multiply numerator and denominator by the radical, then simplify.
b.
