The answer is I believe: 21
Answer:
Step-by-step explanation:
so you are doing 4x times 4x which = 16x
so now you do 16x-9 which = 7x
The polar coordinate system.
Okay, the exponential function is

The start price of it in t=0 is 3,500, as we can see on the graph. Then, the function becomes

Let's see at t=2, where the price is g=2000:

Take natural logarithm:



So, the difference between t=0 and t=2 is

And then we get the change of x in one year equal to 0.035.
So, the final equation is

You can insert any t and see that it is correct, for example t=7
