Use scientific notation to estimate the number of inches in 1,225 miles
madam [21]
First, find the number of inches
<span>1225 Miles = 77616000 Inches

then, move the decimal to until you have a ones place.    </span>
<span>77616000.    the decimal for this number moves to the left SEVEN places.
you end up with 7.7616000
</span>
it will look like this:

7.8 * 10^7

I rounded to the .8 because you didn't state how many significant figures, but it could easily be 7.76 * 10^7

the exponent above the 10 will tell you how many places to move. to get back to your original number, move it back to the right seven places. Of course, you would have to place hold the numbers with 0s. If it were negative, you would move the decimal the opposite way.

Prove: cot(x) sec^4(x) = cot(x) +2tan(x) + tan^3(x)
masha68 [24]
\bf cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}&#10;\qquad\qquad &#10;sec(\theta)=\cfrac{1}{cos(\theta)}\quad\qquad  1+tan^2(\theta)=sec^2(\theta)\\\\\\&#10;tan(\theta)=\cfrac{sin(\theta)}{cos(\theta)}&#10;\qquad \qquad cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}&#10;\\\\&#10;-------------------------------\\\\&#10;cot(x)sec^4(x)=cot(x)+2tan(x)+tan^3(x)\\\\&#10;-------------------------------\\\\

\bf \textit{so, let's do the left-hand-side}\\\\&#10;cot(x)sec^2(x)sec^2(x)\implies cot(x)[1+tan^2(x)][1+tan^2(x)]&#10;\\\\\\&#10;cot(x)[1^2+2tan^2(x)+tan^4(x)]&#10;\\\\\\&#10;cot(x)+2tan^2(x)cot(x)+tan^4(x)cot(x)&#10;\\\\\\&#10;cot(x)+2\cdot \cfrac{sin^2(x)}{cos^2(x)}\cdot \cfrac{cos(x)}{sin(x)}+\cfrac{sin^4(x)}{cos^4(x)}\cdot \cfrac{cos(x)}{sin(x)}&#10;\\\\\\&#10;cot(x)+2\cdot \cfrac{sin(x)}{cos(x)}+\cfrac{sin^3(x)}{cos^3(x)}\implies \boxed{cot(x)+2tan(x)+tan^3(x)}

A poll was conducted in states A, B, and C to determine which candidate voters would most likely vote for. The results are displ
max2010maxim [7]
<span>P(liberal | State A) means that probability of liberal candidates to be voted for within state A. This probability could be calculated by the pattern: number of successful events/total events. The successful events referred here is the number of liberal votes in state A. That is equal to 22. The total events is the total number of votes in state A which is 40. 

Thus, the probability is 22/40 = 0.55</span>
