How to solve an equation for x with natural log of x

Mathematics
1 answer:
Soloha48 [4]4 years ago
4 0
Question is not specific, so can only give a general answer.
As an example:
If the equation is of the form
log(x)=5
then raise each side to the power of e to give
e^(log(x))=e^5
Since e^(log(x))=x, we have
x=e^5.

The Supplemental Security Income (SSI) program, administered by the Social Security Administration (SSA), is the income source of last resort for thelow-income aged, blind, and disabled. As the nation's largest income-assistance program, it paid $38 billion in benefits in calendar year 2006 to roughly 7 million recipients per month. BecauseSSI is means tested, administering the program often requires month-to-month, recipient-by-recipient benefit recomputations. An increase in a recipient's income usually triggers a benefit recomputation. Or, an increase in the recipient's financial assets, which may render the recipient ineligible, would also prompt a recomputation. With this crush of ongoing recomputations, it is of little wonder that administrative simplification is a time-honored mantra for program administrators.

Describe, in your own words, the identity sin^2(x) + cos^2(x) = 1.
Crank

Look at the attached figure. We define the unit circle as a circle with center A in the origin (0,0) and radius 1.

Then, we consider a point P on the circumference. We call \alpha the angle between the positive half of the x axis and the radius AP.

We define

\cos(\alpha) = \overline{AD},\quad \sin(\alpha) = \overline{AC}

As you can see, ACD is a right triangle, and so we have

\overline{AD}^2+\overline{AC}^2=\overline{AP}^2

But since we know that AD is the cosine, AC is the sine, and AP is the radius (which is 1, and remains 1 when squared), we have just found out that

\cos(\alpha)^2+\sin(\alpha)^2=1

Levart [38]

Answer:

9^8

Step-by-step explanation:

9^8=43046721

ln(9^x)=xln(9)

so we search x=ln(43046721)/ln(9)

hope this helps
