Triangle X: 4/5=0.8
Triangle Y: 6/7.5=0.8
(Select the triangles with legs at a ratio of 0.8)
A: 8/10=0.8
B: 3/3.75=0.8
C: 10/12=0.8333333333
D: 12/15=0.8
A, B, and D
I must add though, the wording of this question is very bad.
Answer: y = -1x+8
Step-by-step explanation:
y=mx+b
M is your slope
B is your y-int
<span>Assuming the reaction 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 = rate constant, t = time
Integrating the equation from N = Ni to Nf and t = ti to
tf will result in:
ln (Nf / Ni) = k (tf – ti)
Since k is constant, we can equate to situations.
Situation 1 is triple in size every days, situation 2 is after 20 days.
ln (Nf / Ni) / (tf – ti) = k
ln (3Ni / Ni) / 4 = ln (Nf / 40) / 20
Calculating for Nf,
