Simple interest formula:

$I=prt$

where $I$ =interest, $p$ =principal (how much you put in at first), $r$ =rate as a decimal, and $t$ =number of years.

Let's plug in what we're given.

$I=350\times0.05\times4$

Calculate it out...

$\boxed{I=70}$

The interest earned is $70.00.

A 46 gram sample of a substance that is used to sterilize surgical instruments has a k-value of 0.1374. Find the substance's hal

mars1129 [50]

Answer:

$t=5.0days$

Step-by-step explanation:

Using the formula for the exponential decay that is $N=N_{0}e^{-kt}$ , we have N= $\frac{1}{2}{\times}46=23$ , $N_{0}=46$ and k=0.1374.

Thus, $N=N_{0}e^{-kt}$ becomes

$23=46{\times}e^{-0.1374t}$

$\frac{23}{46}=e^{-0.1374t}$

$\frac{1}{2}=e^{-0.1374t}$

Taking log on both sides, we get

$ln(\frac{1}{2})={-0.1374t}$

$t=\frac{ln\frac{1}{2}}{-0.1}$

$t=\frac{-0.6931}{-0.1374}$

$t=5.0days$

A parasail is at 200.6 feet above the water. After 5 minutes, the parasail is at 120.8 feet above the water. What is the change

kow [346]

Answer:

Change in height of the parasail after 5 minutes = 79.8 feet.

Explanation:

Change in height = Absolute value of the differences of the initial height and final height.

Initial height of parasail = 200.6 feet.

Final height parasail = 120.8 feet.

Change in height of the parasail = 200.6 - 120.8 = 79.8 feet.

Change in height of the parasail after 5 minutes = 79.8 feet.
