What does the Exponential Decay Variables Mean? For Half Lifes Y=Ae^-bX

kompoz [17]

A is the initial population

b is the decay coefficient

X is normally the time.

$Y = Ae^{-bx}$

then is the population half of the initial population of A

for half life you will have

$\frac{Y}{A} = \frac{1}{2}$

so the equation becomes

$\frac{1}{2} = e^{-bX}
\\
\\\ln{ \frac{1}{2}} =\ln{e^{-bX}}
\\
\\ \ln{1}-\ln{2}=-bX
\\bX=\ln{2}$

In one month Kimberly earned $500 at her part-time job, and $50 was withheld for federal income tax. Suppose she earns $750 next

djverab [1.8K]

Answer:

It will be withheld $75 for federal income.

Step-by-step explanation:

Proportions

Assuming the federal income tax is proportional to the earnings, we can establish the following relationship between the income tax (T) and the earnings (E):

T = k.E

Kimberly earned E=$500 and paid T=$50 for federal income tax, With this information, we can calculate the value of k:

50 = k ( 500)

k = 50 / 500

k = 0.1

The model is now:

T = 0.1*E

If Kimberl earns $750 next month, the tax will be:

T = 0.1*($750)

T = $75

It will be withheld $75 for federal income.
