Answer:
exponential: y = 2^(-x)
Step-by-step explanation:
The y-differences are not constant, and the x-y products are not constant. For each increase in x, y is divided by 2, so this is a geometric sequence that can be described by an exponential model. The common factor is 1/2.
A simple way to write the model for this is ...
y = 2^(-x)
Answer:
60°
Step-by-step explanation:
∠ABC-∠CBD=∠1
The price the Rafael paid for the camera is 652 dollars which already has a discount which is 20%.
There are a lot of ways to solve it, however, I'll show you the easiest way.
=> 652 dollars is the 80% of the price since it lessen by 20%
=> 652 / 8 = 81.5 is the 10% of the price.
=> 81.5 * 10 = 815 dollars is the original price of the camera.
9 would be the right answer because -3 ^2 is 6 and 6 times 2 is 12 plus -3 is 9. so 9 is your final answer
