Answer:
6 seconds
Step-by-step explanation:
-12 m is the displacement
Distance covered is 12m
Distance : time
2m : 1 sec
12m : t sec
2/1 = 12/t
t = 6 sec
(0, 15)
(10, 19.34)
m = (19.34 - 15) / (10 - 0) = .434
P(d) - .434d + 15
Given
class charlie records the volume of a liquid as 13.3 milliliters.
the actual volume is 13.6 milliliters
Find the percent error.
To proof
Formula
error = accepted value - measured value
As given in the question
actual volume = 13.6 milliliters
records the volume of a liquid = 13.3 milliliters
error = actual volume - records volume
= 13 .6 - 13.3
= 0.3 milliliters
put all the value in the above formula
we get
on solving the above equation
therefore
percentage error = 2.21 %
Hence proved
In order to solve an equation by factoring, it should be that the equation is equal to zero.
m^2 + 8m + 7 = 0
For this case we have, to do completing the square in order to factor this equation.
<span>
m^2 + 8m = -7
</span><span>m^2 + 8m + 16 = -7 +16
</span><span>(m+4) (m+4) = 9
</span><span>(m+4)^2 = 9
Take the square root of both sides,
m+4 = 3
m = -1</span><span>
