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

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

just needed some points but try socratic
