<span>7.35 x 10^-6 cm per second
This is an exercise in division using scientific notation. So
6.35x10^-1 / 8.64x10^4 = ?
To perform division using scientific notation, you divide the significands as you would normally. So
6.35 / 8.64 = 0.734953704
Then you subtract the exponents. So
-1 - 4 = -5
Giving you a result of
0.734953704 x 10^-5
Notice that the significand in this case is less than 1. That means that you now need to normalize the result, getting a significand that's greater than or equal to 1 and less than 10. We can do this by multiplying the significand by 10 and then subtracting 1 from the exponent. So
0.734953704 * 10 = 7.34953704
-5 - 1 = -6
Giving a new result of:
7.34953704 x 10^-6
And don't forget about significant figures. Since the least precise piece of data we have is 3 digits, we should round the result to 3 digits. So the final answer is 7.35 x 10^-6 cm per second.</span>
No solution means u can graph the two equations and it would form parallel lines and would never intersect while, no real solution when graph the two equations would form the same line. When dealing with absolute value equation an equation with a degree larger than one,theres a chance it can be multiple solutions
