A32 gram sample of a substance that’s a by-product of fireworks has a k-value of 0.1368. find the substance’s half-life, in days. use formula n=n0e-kt, t= time in days. pls

t=5.1 days

Step-by-step explanation:

We know that the formula is:

Where N is the amount of substance after a time t, is the initial amount of substance, k is the rate of decrease, t is the time in days.

We want to find the average life of the substance in days

The half-life of the substance is the time it takes for half the substance to disintegrate.

Then we equal N to 16 gr and solve the equation for t

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
