Answer:
C. y = Ae^(-(x-b)²/c)
Step-by-step explanation:
A is a model of exponential growth.
B is a model of exponential decay.
D is a "logistic function" model of growth in an environment of limited resources. It produces an "S" shaped curve.
The given bell-shaped curve can be described by the function of C, which decays either side of an axis of symmetry.
Answer: 9ft² and 12.25ft²
Step-by-step explanation:
Solve for cos(t) and sin(t):
x = 2 + 3 cos(t) ⇒ cos(t) = (x - 2)/3
y = 1 - sin(t) ⇒ sin(t) = 1 - y
Recall the Pythagorean identity,
sin²(t) + cos²(t) = 1
It follows that
((x - 2)/3)² + (1 - y)² = 1
or
(x - 2)²/9 + (y - 1)² = 1
Answer:
1. 4.7
2. 5,082
Step-by-step explanation:
1. To find the volume of a cone you use this formula 
. The diameter is 3 so to find the radius, divide it by 2 (3/2=1.5) and we know the height. Input the numbers into the formula and solve 
which is equal to 
. To find HALF, divide that answer by 2. 
, round to the nearest tenth, making the answer 4.7!
2. To find the volume of a rectangular prism you use 
. Input the numbers, 
to find the amount of water for the bigger tank (5,760). Now follow the same process to find the amount of water for the smaller tank 
which is 678. Now subtract the smaller tank amount (678) from the larger tank since you're taking the water from the bigger tank to fill the smaller one which equals 5,082.
