<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:
1/2
Step-by-step explanation:
It rises 1 and goes 2 units to the left, which is what rise/run means
And a tip:
I can tell you're using Goggle Forms. If you hit ctrl + U, you can find the answers to the questions in the code
Answer:
18ft
Step-by-step explanation:
just add all the sides. since it’s a rectangle, you there is 2 sides that’s 3ft long and that are 6ft long. so you would do 3+3+6+6
What is the question asking?
Pythagoras theorem only works for right triangle (90 degree)
Trigonometry (sin, cos, tan) works everywhere!
