Tritium, the heaviest form of hydrogen, is a critical element in a hydrogen bomb. It decays exponentially with a half-life of ab

out 12.3 years. Any nation wishing to maintain a viable hydrogen bomb has to replenish its tritium supply roughly every 3 years, so world tritium supplies are closely watched. Construct an exponential function, Upper A left-parenthesis t right-parenthesis, that shows the remaining amount of tritium as a function of time as 100 grams of tritium decays (about the amount needed for an average size bomb) where Upper A is measured in grams and t is measured in years.
Round numbers to three decimal places, if required.

A(t)=100e^(-rt).
We need to find r. When t=12.3 A(t)=50 (half of 100) = 100e^(-12.3r).
ln(0.5)=-12.3r so r=ln(0.5)/-12.3=0.0564 approx. So A(t)=100e^(-0.0564t).

In the numerical sentence below, A = 8, D = 1/2 , and F = 1/4. What are the values B, C, and E if the sentence below is equivale
a_sh-v [17]
B=3; C=16; and E=4096.

Using the information we have gives us

8^B \times C^{\frac{1}{2}} = E^{\frac{1}{4}}

We know that:
8^B = 2;&#10;\\&#10;\\C^{\frac{1}{2}}=4;&#10;\\&#10;\\E^{\frac{1}{4}}=8

We know that 2³ = 8, so B = 3.

To "undo" a square root, we square the number; 4²=16, so C = 16.

To "undo" a fourth root, we raise the answer to the fourth power; 8⁴ = 4096, so E = 4096.
