Answer:
Step-by-step explanation:
From the figure attached,
Given:
Lines AB and CD are intersecting each other at a point E.
To prove:
∠ACB ≅ ∠DEB
Statements Reasons
1). ∠AEC + ∠BEC = 180° 1). Linear pair theorem
2). ∠DEB + ∠BEC = 180° 2). Linear pair theorem
3). ∠AEC + ∠BEC = ∠DEB + ∠BEC 3). Transitive property of equality
4). ∠AEC = ∠DEB 4). Subtraction property of equality
Answer:
is it positive 14

Answer:20
Step-by-step explanation:
i got it right in my dca
<span>Assuming the growth is of 1st order, we can
start using the formula for rate of 1st order reaction:</span>
dN / dt = k * N
Rearranging,
dN / N = k dt
Where N = amount of sample, k = growth factor, t = time
Integrating the equation from N = Ni to Nf and t = ti to
tf will result in:
ln (Nf / Ni) = k (tf – ti)
Finding for the growth factor k:
k = ln (Nf / Ni) / (tf – ti)
k = ln (1.022 Ni / Ni) / 1 year
k = 0.02176 / year
The population in 2011 is:
ln (Nf / Ni) = k (tf – ti)
ln (Nf / 25000) = (0.02176 / year) * (2011 – 2006)
<span>Nf = 27,873.7 = 27,874</span>
