A radioactive nuclide has a half-life of 10 days. At what rate does the substance decay each day?

6.7% decrease each day

Step-by-step explanation:

Half life: 10 days

Fraction = 0.5^(t/10)

Where t is the no. of days

Per day: t = 1

0.5^(1/10)

0.9330329815 × 100 = 93.30329917

Decrease of: 100 - 93.30329917

= 6.696700846% each day

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
