X = 16y^2 + 1
x - 1 = 16y^2
(x - 1)/16 = y^ 2
( (x-1) / 16 ) ^1/2 = y
( (x-1) ^ 1/2 ) / 4 = y
Answer:
58
Step-by-step explanation:
Complementary angles add up to 90
Za + Zb = 90
32 + Zb = 90
By simple algebra:
Zb = 58
The answer to this is 756 hours. Because first you must multiply the number of miles each flight is x the miles per minute. Next you multiply that answer by the number of trips. The answer would be how many minutes, but the question asks "how many hours", and there's 60 minutes in an hour so divide that answer by 60 and that will equal 756 hours.
Answer:
sin(3π/7 - 2π/21)
Step-by-step explanation:
Given
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21
Required
Write a trigonometry formula for the expression
Using sine formula, we have:
sin(A - B) = sinAcosB - cosAsinB
The above formula can be applied to the given expression where
A = 3π/7
B = 2π/21
So, the trigonometry formula is:
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21= sin(3π/7 - 2π/21)
Hmmm... the partial products?
