Answer:
Step-by-step explanation:
I think you have the question incomplete, and that this is the complete question
sin^4a + cos^4a = 1 - 2sin^2a.cos^2a
To do this, we can start my mirroring the equation.
x² + y² = (x + y)² - 2xy,
This helps us break down the power from 4 to 2, so that we have
(sin²a)² + (cos²a)² = (sin²a + cos²a) ² - 2(sin²a) (cos²a)
Recall from identity that
Sin²Φ + cos²Φ = 1, so therefore
(sin²a)² + (cos²a)² = 1² - 2(sin²a) (cos²a)
On expanding the power and the brackets, we find that we have the equation proved.
sin^4a + cos^4a = 1 - 2sin^2a.cos^2a
Answer:
9.5
Step-by-step explanation:
If c to a is 19 then you divide the distance by 2 and you get 9.5 for the two distances.
Answer:
No, it is not function. The answer is the last option in the multiple choice sequence.

Answer:
6/5
Step-by-step explanation:
brainly plz
but if one whole is 5 then one has 5 and the other has 1 and 5+1=6 and one whole=5 thus is 6/5
