Answer:
{-8, -4, -2, -1, 1, 2, 4, 8}
Step-by-step explanation:
Possible rational roots are positive and negative divisors of the constant 8:
{-8, -4, -2, -1, 1, 2, 4, 8}
_____
<em>Additional comment</em>
This polynomial has no rational roots. Its two real roots are both negative and irrational.
First you want to find a multiple that's very close to 28. It's 24, so subtract 28-24 which is 4. 4 biscuits are left.
Hope that helped:)
Answer:
66 in approx
Step-by-step explanation:
Given data
Radius= 10.5 inches
The circumference is given as
C= 2πr
Substitute
C=2*3.142*10.5
C=65.982
Hence the Circumference is 66 in approx
Answer:
cos 2x = (√7) / 4
Step-by-step explanation:
sin x - cos x = 1/2
(sin x - cos x)² = (1/2)²
sin²x - 2 sin x cos x + cos² x = 1/4
1 - 2 sinx cosx = 1/4
2 sinx cosx = 3/4
sin 2x = 2 sinx cosx = 3/4
sin² 2x = 9/16
cos² 2x = 1 - sin² 2x = 1 - 9/16 = 7/16
cos 2x = (√7) / 4
