WebFeb 27, 2024 · Explanation: Use trig identity: 2sin2a = 1 −cos2a. In this case, a = (22∘5) and 2a = 45∘ -->. 2sin2(22.5) = 1 − cos45 = 1 − √2 2 = 2 − √2 2. sin2(22.5) = 2 −√2 4. sin(22.5) = ± √2 −√2 2. Since sin (22.5) is positive, take the positive value. sin(22.5) = √2 −√2 2. Web2-2-1 Press Rules. 1. No middle.

WebIn this problem, we are given that it takes 444 years for the substance to lose 1/2 of its radioactive nuclei, so in each year, it will tick through only one-444th of its half-life. So our exponent is t/444. We then can say that N (t) = N₀ (1/2) ^ (t/444) You asked what the constant value is for mercury 194. WebEnter X number and Y number in the corresponding cells.
