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:
<h3>
Assuming A, B, and C are collinear and B is between A and C then x = -2
2</h3>
Step-by-step explanation:
Assuming A, B, and C are collinear and B is beetween A and C
AB + BC = AC
48 + 2x + 139 = x + 165
2x + 187 = x + 165
x = -22

H^2 = 12^2 + 16^2
H^2 = 144 + 256
H^2 = 400
H = square root of 400 = 20
