Answer: The exponential model for the area would be
.
Step-by-step explanation:
Since we have given that
Initial square miles = 8
It gets tripled in every 4 hours.
So, in every 4 hours, it become 3.
In every 1 hour, it becomes 
So, According to question, an exponential model for the area would be

Hence, the exponential model for the area would be 
Answer:
4b<30
Step-by-step explanation:
product means multiply so 4•b or 4b
less than so<
Answer:$ 43.20
Step-by-step explanation: I think this is right I just worked it out
Answer:
<u><em>(x, y) -------> ( - x , y - 10 )</em></u>
Step-by-step explanation:
Titus is not correct.
There are two transformations will correctly prove FEDCBA ≅ F'E'D'C'B'A'
First transformation is Reflection over y-axis , then translation 10 units down.
The final formula is <em>( - x , y - 10 )</em>
Cylinder:
V = pi * r^2 * h
V = 3.14 * 9^2 * 11
Simplify exponent:
V = 3.14 * 81 * 11
Multiply:
V = 2797.74
Sphere:
V = 4/3 * pi * r^3
V = 4/3 * 3.14 * 9^3
Simplify exponent:
V = 4/3 * 3.14 * 729
Multiply:
V = 3052.08
Cone:
V = 1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 12^2 * 20
Simplify exponent:
V = 1/3 * 3.14 * 144 * 20
Multiply:
V = 3014.4
So the Sphere holds the most.
