Marsha deposited 7,500 into a savings account 3 years ago. The simple interest rate is 5%. How much money did Marsha earn in int

Ludmilka [50]

Answer:

$1,125 in interest.

Step-by-step explanation:

We need the formula of I = P * i * t where P is the total principle, i is the rate of interest per year, and t is the total time in years.

So we have

P = $7,500

i = 5%

t = 3 years

I = 7500 * 0.05 * 3

I = 1,125 (Interest)

Now we need to find the amount using A = P + I

A = 7,500 + 1,125

A = 8,625

Therefore $8,625 is our total. While our interest is $1,125.

An Archaeologist in Turkey discovers a spear head that contains 51% of its original amount of C-14. Find the age of the spear he

disa [49]

Use given half-life for C-14 of 5,730 years.

The exponential decay function:
$y = e^{-kt}$
plug in half life, solve for 'e^(-k)'
$0.5 = e^{-5730k} \\ \\ 0.5 = (e^{-k})^{5730} \\ \\ e^{-k} = (0.5)^{1/5730}$

Sub into original decay function, plug in 0.51 for 'y' and solve for 't'

$y = e^{-kt} = (e^{-k})^t \\ \\ 0.51 = (0.5)^{t/5730} \\ \\ ln(0.51) = \frac{t}{5730} ln(0.5) \\ \\ t = 5730 \frac{ln 0.51}{1n 0.5}$
