Answer:
Option 1:
Step-by-step explanation:
Find the slope of the perpendicular line by finding the negative reciprocal of the original slope. (Negative reciprocal = flip upside down and add a negative). So we get -4 for the perpendicular slope.
Next, we know the point (-2,6) is on the line, so we can get x=-2 and y=6.
Plug this into point-slope form:
Answer
Find out the percent error in Annie's estimate .
To prove
Formula
As error = approx value - exact value
As given
Annie estimates that the height of a bookcase is 78.25 in.
The actual height is 75.50 in.
approx value = 78.25 in.
actual value = 75.50 in.
error = 78 .25 - 75 .50
= 2.75
put in the formula
Percentage error = 3.64 % (approx)
Therefore the Percentage error be 3.64 % (approx).
