That number is already in standard form.
If you need to write it in scientific notation, then do this.
<span>731,934,000
Look at all the digits that are not zero, and place the decimal point in a way that you have a number from 1 to less than 10.
Take 731934, and place the decimal point after the 7 giving 7.31934.
The original decimal point was after the third zero, so now using the original number, count the number of decimal places you moved the decimal point. The decimal point moved 8 places to the left. That means you need an exponent of 8.

Answer:
a) is the equation of the curve that makes an angle π/3.
b) is the equation of line through the point (4,4).
Step-by-step explanation:
Given:
A line from origin which makes an angle of with x-axis.
A vertical line from .
We have to write the equation of the curves in Polar or Cartesian format.
Step wise:
a) A line from origin which makes an angle of with x-axis.
To write the equation of the above line in Polar coordinates is more desirable as the angles could be defined well in polar form.
So,
⇒ ...equation (i)
⇒ ...here
is the slope
The slope in terms of (angle) can be written as,
⇒
Plugging the values of the angle, .
⇒ ...equation (ii)
Now re-arranging the equation (i) we can write it as,
⇒
b) A vertical line from .
<em>Note:</em>
<em>The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept .</em>
To write the above point in Cartesian coordinate is more acceptable and easy for us.
⇒
Then,
y = sq-rt(3) x is the equation of the curve that makes an angle π/3.
and x = 3 is the equation of line through the point (4,4).
