Light travels at a speed of 186,282 miles per second. How could this number be expressed in scientific notation?
1)1,862.82 x 10 x10 x10
2)1.86282 x 10 x10 x 10 x10 x10
3)1.86282 x 10 x10 x10 x10
4)186.282 x -10 x-10 x -10
A cricket produces 116 chirps per minute at 72 degrees Fahrenheit and 177 chirps per minute at 80 degrees Fahrenheit.
Find a linear equation that models the temperature as a function of the number of chirps per minute .
To express a number in scientific notation, we need to write it in the form of a coefficient multiplied by a power of 10. In this case, the speed of light is 186,282 miles per second.
The correct way to express this number in scientific notation is option 3) 1.86282 x 10^5.
To find this answer, follow these steps:
1) Count the number of places you need to move the decimal point to make the number between 1 and 10. In this case, we would need to move the decimal point 5 places to the left.
2) Write the number in the form of a coefficient multiplied by 10 raised to the power of the number of places you moved the decimal point. In this example, the coefficient would be 1.86282, and the power of 10 would be 5.
Therefore, the speed of light, 186,282 miles per second, can be expressed in scientific notation as 1.86282 x 10^5.
