Answer: 100pi
Step-by-step explanation:
Look at attachment
Since it is perpendicular to y=3x-1, the slope must be a negative reciprocal.
there the slope of the perpendicular line is

So now we have,

To find b, we use the point that the line passes through and substitute it to the y and x values.

which would give us b=5/3
Therefore, the equation of the line is
Answer:
No
Step-by-step explanation:
The sum of the digits is 40 which is not divisible by 9, so it is not divisible by 9
<span>x² - 18x - 4 = ox² - 18x = 4x² - 18x + (18/2)² = 4 + (18/2)²x² - 18x + 81
</span>
Round to tens: 240 + 370 = 610
round to hundreds: 200 + 400 = 600
hope this helps
