Determine if y=(1/5)^x is growth or decay

The function is decaying.

Step-by-step explanation:

Given:

The above equation can also write as below,

Now from the function we can see that as we are increasing the value of x the value of function is decreasing.  Let take some values of x and then find out the value of function at those value of x

When x = 1 ,

When x = 2,

When x = 3,

So, from the above examples, we can see that the value of function is decreasing on increasing the value of x. Hence the function is decay

step-by-step explanation:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
