Step-by-step explanation: hope this help
B, C and D are exponential decay.
Half-lives are given by exponential function, and since they are decreasing, it is decay.
With the teams being eliminated, this is decay.
Bacteria can be represented by exponential functions, and it is decreasing.
Answer: 64pi-30
Step-by-step explanation:
Area of the circle is (pi)(8^2)=64pi
Area of the parallelogram is (5)(6)=30
So the total area is 64pi-30 (which you can round yourself)
This one was difficult one but is made to equations like such.
x+7=2y
x+y-9=13
using substitution i came to
x(the first number)=12.333
y(the second number)=9.667
hope i helped
