Answer:
B) -3
Step-by-step explanation:
The coefficient is the numerical value placed before and multiplying the variable (x).
Answer:
m=3/2
look how many units go up and to the side between 2 points
As seen here, we go up 3 units and over 2 units from (0, -3) to (2, 0.) Therefore, slope is 3/2
Step-by-step explanation:
A half-life of the isotope is 15 days and at start its mass is 32 g.
A table:
t: m:
0 32 g
15 16 g
30 8 g
45 4 g
60 2 g
75 1 g
In the first column is used an arithmetic sequence ( a 1 = 0, d = 15 ).
In the second column is used a geometric sequence ( a 1 = 32, r = 1/2 )
