Recall that m(t) = (1/2)^t/h for radioactive decay, where h is the half-life. Suppose that a 500g sample of phosphorus-32 decays
katrin2010 [14]

The question is incomplete, here is the complete question:

Recall that m(t) = m.(1/2)^t/h for radioactive decay, where h is the half-life. Suppose that a 500 g sample of phosphorus-32 decays to 356 g over 7 days. Calculate the half life of the sample.

<u>Answer:</u> The half life of the sample of phosphorus-32 is 14.28days^{-1}

<u>Step-by-step explanation:</u>

The equation used to calculate the half life of the sample is given as:

m(t)=m_o(1/2)^{t/h}

where,

m(t) =  amount of sample after time 't' = 356 g

m_o = initial amount of the sample = 500 g

t = time period = 7 days

h = half life of the sample = ?

Putting values in above equation, we get:

356=500\times (\frac{1}{2})^{7/h}\\\\h=14.28days^{-1}

Hence, the half life of the sample of phosphorus-32 is 14.28days^{-1}

Hoshi walks 10 meters in 3 seconds. She walks the same at this rate for 50 seconds. How far does she walk?
svlad2 [7]
10m ----> 3 sec

x meters ----> 50 sec

50(10) = 3x

500 = 3x

devide both in 3

x = 166.66 m

$35,125 loan, a feat which took ten years of quarterly payments. The loan had an interest rate of 7.44%, compounded quarterly. I
Darya [45]
First find the amount of each payment:
35,125 = P(\frac{(1+i)^{40} -1}{i (1+i)^{40}}) , i = \frac{.0744}{4}  \\  \\ P = 1252.70

The total cost will be 40 payments plus service charges.
40*1252.70 + 5180.70 = 55,288.90

The percentage is the service charge divided by total cost:
X = \frac{5180.70}{ 55,288.90} = .0937 = 9.37\%
