Answer: B) It is a multiplicative, because the output is equal to the input times 2.
Step-by-step explanation:
I think the answer would be 3
Answer:
So the center is at (20,.05) and the radius is 9
Step-by-step explanation:
The equation of a circle can be written in the form
(x-h) ^2 + (y-k) ^2 = r^2
where (h,k) is the center and r is the radius
Lets write our equation in that form
( x-20)^2 + (y-0.05)^2 =81
( x-20)^2 + (y-0.05)^2 =9^2
So the center is at (20,.05) and the radius is 9
Answer:
The equations that represent an exponential decay are;
A; [y = (0.1)ˣ]
B; [y = 2·(0.3)ˣ]
Step-by-step explanation:
An exponential decay is given by the following formula;
y = a·bˣ
Where;
b < 1
For option A, we have; [y = (0.1)ˣ]
Here; a = 1, b = 0.1 < 1, therefore, the function represents an exponential decay
For option B, we have; [y = 2·(0.3)ˣ]
Here; a = 2, b = 0.3 < 1, therefore, the function represents an exponential decay
For option C, we have; ![\left[y = \left(\dfrac{4}{3} \right)^x\right]](https://tex.z-dn.net/?f=%5Cleft%5By%20%3D%20%5Cleft%28%5Cdfrac%7B4%7D%7B3%7D%20%5Cright%29%5Ex%5Cright%5D)
Here; a = 1, b = 
, therefore, the function does not represent an exponential decay
For option D, we have; ![\left[y = \left(\dfrac{7}{5} \right)^x\right]](https://tex.z-dn.net/?f=%5Cleft%5By%20%3D%20%5Cleft%28%5Cdfrac%7B7%7D%7B5%7D%20%5Cright%29%5Ex%5Cright%5D)
Here; a = 1, b = 
, therefore, the function does not represent an exponential decay
Answer/Step-by-step explanation:
Area of a rectangle = Length × Width
Width of the large rectangle = a
Length of the large rectangle = (2 + 3 + 4)
Therefore:
Area of the large rectangle = a(2 + 3 + 4)
