Okay. So the formula for the amount of time is I / Pr, meaning you multiply the principal and the rate in decimal form together, and you divide the amount of interest by that number. The formula for finding the interest rate is I / Pt, meaning you multiply the principal and time, and the you divide the amount of interest by that number. With a decimal, be sure to multiply by 100 to get the whole percentage. With that being said, if you solve this correctly, here are your answers.
Principal: $6,631
Interest Rate: 8.05%
Time: 33 months
Simple Interest: $1,467.94
Principal: $884,706
Interest Rate: 5.42%
Time: 40 months
Simple Interest: $159,931
Note: For times in months, you'll have to do some conversion into decimals, but you know that 12 months equal 1 year, so you can divide the time period by 12. For the second part, I happened to get 5.43% when I worked it out, but a calculator happened to round off to 5.42%, so it's a bit confusing, but those are the answers.
Answer:
The age of the spear head to the nearest year is 1845 years
Step-by-step explanation:
We know that
half life time of C-14 is 5730 years
so, h=5730
we can use formula
now, we can plug value
an archaeologist in turkey discovers a spear head that contains 80% of its original amount of C-14
so,
we can plug it
now, we can solve for t
So,
The age of the spear head to the nearest year is 1845 years
Answer: Polynomials are consists of several terms, so in this expression, we can split it into two parts to find a multi-term grouping.
X2+5x is one polynomial (binomial to be exact).
(5x-3) is another polynomial (binomial).
