PLZZZ HELP ILL MARK BRAINLIEST Describe at least two similarities between constructing a perpendicular line through a point on a line and constructing a
perpendicular through a point off a line.

If you want to draw a perpendicular line from a point on a line, you would measure a 90 degree angle from that point and then draw the line outward.

On the other hand, if you wanted to draw a perpendicular line connecting a line and a point off of the line, you would have to connect the point to the location on the line that forms a 90 degree angle.

Both methods involve making a 90 degree angle between two lines.

So we like to say that they are opposite reciprocal. Or, we could say, the opposites of the reciprocal. Some people say negative, reciprocal. Another way to put that is, if the slope of one line is M someone and the slope of the perpendicular line is M sub two. When you multiply them, you're going to get negative one. Another way to put it is that the slope of line to M sub two will be negative one divided by the slope of line one m sub one many ways to say it. Here's an example. If the slope of one line is 2/7 then the slope of the perpendicular line would be negative. Seven House.

THANK MY ANSWER AND MARK ME AS BRAINLIST

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
