Answer: 
Step-by-step explanation:
You are correct in stating you have a decay. This is because the base of the exponential 0.82 is in the form 1+r where 1+r = 0.82 solves to r = -0.18
The negative r value means we have decay.
The rate of decay is 18% since 0.18 = 18/100 = 18%
For example, if we started with 100 items then after 1 unit in time, you'd have 82 items since 100-18 = 82
Answer:
D. x = -5/2, x = -1/2
Step-by-step explanation:
2x² + 7x + 5 = 0
(2x + 5)(x + 1) = 0
2x + 5 = 0 or x + 1 = 0
2x = -5 or x = -1
x = -5/2 or x = -1/2

Answer:
B
Step-by-step explanation:
You just need to find the volumes of both container and soap and divide them. So;
Volume of Soap = 15cm * 8cm * 6cm = 720 cm^3
Volume of Container = 165cm * 40cm * 96cm = 633600 cm^3
Dividing them gives = 633600 cm^3 / 720 cm^3 = 880
Answer is B.
