If you can explain your answer that’d be great!! Thank you!

Rasek [7]

Answer:

$A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}$

Step-by-step explanation:

This half life exponential decay equation goes by the formula:

$A(t)=A_{0}e^{kt}$

Where

$k=\frac{ln(\frac{1}{2})}{Half-Life}$

Since half life is given as 22, we plug that into "Half-Life" in the formula for k and then plug in the formula for k into the exponential decay formula:

So,

$k=\frac{ln(\frac{1}{2})}{Half-Life}\\k=\frac{ln(\frac{1}{2})}{22}$

Now

$A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}$

third choice is correct.

Answer:

Element Valence electrons

Nitrogen 5

Silicon 4

Oxygen 6

Magnesium 2

Explanation :

Valence electrons : Valence electrons are the electrons which is present on the outermost shell of the electron.

The given element is nitrogen that belongs to group 15 and the atomic number 7.

The number of electrons present on nitrogen element are 7.

The electronic configuration of nitrogen element is,

The number of valence electrons present on nitrogen element are, 5.

The given element is silicon that belongs to group 14 and the atomic number 14.

The number of electrons present on silicon element are 14.

The electronic configuration of silicon element is,

The number of valence electrons present on silicon element are, 4.

The given element is oxygen that belongs to group 16 and the atomic number 8.

The number of electrons present on oxygen element are 8.

The electronic configuration of oxygen element is,

The number of valence electrons present on oxygen element are, 6.

The given element is magnesium that belongs to group 2 and the atomic number 12.

The number of electrons present on magnesium element are 12.

The electronic configuration of magnesium element is,

The number of valence electrons present on magnesium element are, 2.

Compare the values of the underlined digits 6,300 and 530 with three being the underlined digit.

NNADVOKAT [17]

In Comparing 2 underlined numbers which is 3, we need to find its place value In order to be able to find the difference of each given numbers.

First is 6300 => 6000 + 300 or may also say as 6 thousands + 3 hundreds
therefore the value of underlined number is hundreds

next, 530 => 500 + 30 or may also say as 5 hundreds + 3 tens.
Therefore, the value of underlined number tens.

Thus, the difference between the 2 underlined numbers is, the first given digit falls at hundreds place and the second is in tens place.

Ralph Chase plans to sell a piece of property for $170000. He wants the money to be paid off in two waysminusa short-term note

PSYCHO15rus [73]

Answer:

Amount of short term note = $90,000

Amount of long term note = $80,000

Step-by-step explanation:

Data provided in the question:

Total amount = $170,000

Interest rate of short term note = 10%

Interest rate in long term note = 8%

Total annual interest paid = $15,400

Now,

Let the amount of short term interest be 'x'

thus,

amount of long term interest will be ($170,000 - x)

also,

Interest on short term note + Interest on long term note = Total interest

or

⇒ 0.10 × x + 0.08 × ($170,000 - x) = $15,400

or

0.1x + $13,600 - 0.08x = $15,400

0.02x = $15,400 - $13,600

or

0.02x = $1,800

or

⇒ x = $90,000

Hence,

Amount of short term note = $90,000

Amount of long term note = $170,000 - $90,000 = $80,000
