Answer:
D
Step-by-step explanation:
To compare the two, get the same denominator, so multiply -8/18 by 27 on the numerator and denominator, and multiply -17/27 by 18 on the numerator and denominator. That gives -216 /486 and -306 /486. On a number line, the one on the left is less. That greater than symbol is correct. Both to the left of 0, -8/18 on the right of -17/27.

Your Answer is the second option, could i get brainliest?
<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,
<span>Nf =

Answer:

Step-by-step explanation:
The value of the discriminant determines the nature of the roots
• If b² - 4ac > 0 then roots are real and distinct
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 then roots are not real
Here b² - 4ac = 4 > 0
Hence roots are real and distinct
