The half price of helium-5 is 7.6 X 10 to the power of negative 22 seconds and the half-life helium -9 is 7 x 10 to the power of
Digiron [165]

Answer:

Approximately 9.211 times

Step-by-step explanation:

Given

x = 7.6 * 10^{-22}s --- half life of helium-5

y = 7 * 10^{-21}s --- half life of helium-9

Required

How many times greater is y than x

To do this, we simply divide y by x

\frac{y}{x} = \frac{7 * 10^{-21}s}{7.6 * 10^{-22}s}

\frac{y}{x} = \frac{7 * 10^{-21}}{7.6 * 10^{-22}}

Apply law of indices

\frac{y}{x} = \frac{7 * 10^{-21--22}}{7.6}

\frac{y}{x} = \frac{7 * 10^{-21+22}}{7.6}

\frac{y}{x} = \frac{7 * 10}{7.6}

\frac{y}{x} = \frac{70}{7.6}

\frac{y}{x} = 9.211

For this case we will define the following:
 A, B: are the values of the triangle angles
 a, b: are the values of the lengths of the sides opposite the angles A, B.
 We then have to use the law of the sine:
 \frac{sinB}{b} = \frac{sinA}{a}
 Clearing the angle B we have:
 sinB = \frac{sinA}{a}*b
 B = arcsin(\frac{sinA}{a}*b)
 Substituting values we have:
 B = arcsin(\frac{sin113}{200}*134)
 B = 38.08
 Answer:
 
the following is true:
 
A. angle B=38.08 degrees
