The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass
Tju [1.3M]

Answer:

6.56 g

Step-by-step explanation:

We can write the mass of radioactive isotope left after a time t by using the equation

N(t)=N_0 (\frac{1}{2})^{\frac{t}{t_{1/2}}}

where

N_0 = 210 g is the initial amount of radioactive isotope

t_{1/2} is the half-life

t is the time

In this problem, we want to know the amount of radioactive isotope left after 5 half-lives, so after

t=5 t_{1/2}

Substituting into the equation, we have

N(t)=(210 g) (\frac{1}{2})^{\frac{5 t_{1/2}}{t_{1/2}}}=\frac{210 g}{2^5}=6.56 g

If cosA=3√2/5,then show that cos2A=11/25
Kobotan [32]

Answer:

Step-by-step explanation:

Cos 2A = 2Cos² A - 1

             = 2*(\frac{3\sqrt{2}}{5})^{2}-1\\\\=2*(\frac{3^{2}*(\sqrt{2})^{2}}{5^{2}})-1\\\\=2*\frac{9*2}{25} - 1\\\\=\frac{36}{25}-1\\\\=\frac{36}{25}-\frac{25}{25}\\\\=\frac{11}{25}
