Answer
Find out the what is the percent error in the measurement, to the nearest tenth of a percent .
To prove
Formula
Where error = | Approx - Exact |
As given
Karen measures the width of a garden plot and records that it is 44.25 meters. Its actual width is 45.5 meters.
Approx value = 44.25 meters
Actual value = 45.5 meters
error = | 44.25 - 45.5 |
= |-1.25|
= 1.25
Put in the formula
Percentage error = 2.7%
Therefore the percentage error is 2.7% .
Answer: -18
<u>Explanation:</u>
Average rate of change is slope: . Need to find the y-coordinates:
g(x) = -x² - 4x
g(6) = -(6)² - 4(6)
= -36 - 24
= -60
⇒ (6, -60)
g(8) = -(8)² - 4(8)
= -64 - 32
= -96
⇒ (8, -96)
m =
=
= -18
