Answer:
Step-by-step explanation:
EARNINGS FOR YEARS = PAY RATE/HOUR * HOURS/WEEKS * WEEKS/YEAR * YEARS
EARNINGS FOR 15 YEARS = 21.75/hour * 40 hours/week * 52 weeks/year * 15 years
Earnings = $678,600
Answer:
113.1
Step-by-step explanation:
A = πr²
A = π (6)²
A = π (36)
A = 113.09 = 113.1
Using an exponential function, it is found that the bottle contains 255,960 atoms of tritium after 11 years.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem:
- The bottle initially contained 450,000 tritium atoms, hence A(0) = 450000.
- The amount decays by about 5% per year, hence r = 0.05.
Thus, the equation is given by:



After 11 years, the amount is given by:

The bottle contains 255,960 atoms of tritium after 11 years.

The scale length is 9cm and the scale is 6cm/15ft which is 3cm/5ft, so we can say:
9cm(5ft/3cm)=15ft for the length
If you wanted the width too...
4cm(5ft/3cm)=20ft/3 (6'8", 6ft 8in)
