The half life is 14.4 seconds because the half life is the time it takes for half of a sample to decay.
Hope this helps!
W is 5 units
w=(P-2l)/2
w=(30-2(10))/2
w=(30-20)/2
w=(10)/2
w=10/2
w=5
Answer:
108° and 72°
Step-by-step explanation:
let one angle be x then the other angle is
x
the sum of the 2 angles = 180°, hence
x +
x = 180 ( combining the left side )
x = 180
multiply both sides by 3 then divide both sides by 5
5x = 540 ⇒ x = 108
the 2 angles are x = 108° and
x = 72°
- 3x + 2 ( - 6x² + 13x - 6 )
= - 3x - 12x² + 26x - 12
= - 12x² + 23x - 12
