Situation: Find the substance's half-life, in days.
Round your answer to the nearest tenth.
A 45 gram sample of a substance that's
used to sterilize surgical instruments has
a k-value of 0.15.
Enter the correct answer.
N = Noekt
이
DONE
No = initial mass (at time t = 0)
N = mass at time t
k= a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
