Situation: A 48 gram sample of a substance that's
used for drug research has a k-value of
0.1371.
Find the substance's half-life, in days.
Round your answer to the nearest tenth.
Enter the correct answer.
N = Noe
-kt
DONE
No = initial mass (at time t = 0)
ĐOO
GO
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

d is correct

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

x< 2
