Answer:
f(x) = 6x²-3
f(x) = 0
6x²-3 = 0
6x² = 3
x² = 3/6
x² = 1/2
x = 1/√2 , -1/√2
Roots of f(x) = 1/√2 , -1/√2
Verification = (i) 6(1/√2)² - 3
= 6(1/2) - 3
= 3-3
= 0
(ii) 6(-1/√2)² - 3
= 6(1/2) - 3
= 3-3
= 0
Don't bet any money on this but I think its [Pt(NH3)3] Cl2
Answer: Atomic number
Explanation: Atomic numbers never change, they stay the same which is why they are what elements are identified by
Fundamental frequency, f₀ = 84 Hz
Second harmonic is 2f₀ = 2* 84 Hz = 168 Hz
The mass of a neutron is 1.0086
