Answer:
Hence, 0.00000103 can be expressed as
.
Step-by-step explanation:
- Given 0.00000103
- Move the decimal point so that the factor is greater than or equal to 1 but less than 10 .
- Then count n and write no. as a product with a power of 10 .
Step 1 of 1
Consider 0.00000103,
1.03
Decimal has moved 6 places to right.
The power will be negative as the original no. is less than 1 .

It is 20 because the 5 is in the ones place so the 2 has to be in the 10 place which makes it 20
Answer:
The slope of a line parallel to this line will be: -7/9
The slope of the perpendicular line will be:

Step-by-step explanation:
We know the slope-intercept form

Here,
Given the equation

simplifying to write in the lope-intercept form

Thus, the slope of the line is: -7/9
The slope of a line parallel to the line:
We have already determined that the slope of the line is: -7/9
- We know that the parallel lines have the same slope.
Thus, the slope of a line parallel to this line will be: -7/9
The slope of a line perpendicular to the line:
We have already determined that the slope of the line is: -7/9
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.
Thus, the slope of the perpendicular line will be:
