Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. I will assume the function is:

f(t) = 15(0.86)^t

Required

Determine the rate of decay

In an exponential function f(x) = ab^x,

The decay rate of the function is calculated as:

1 - r = b

By comparison:

b = 0.86

So, the equation becomes:

1 - r = 0.86

Make r the subject

r = 1 - 0.86

r = 0.14

<em>The rate of decay is 0.14</em>

If x/y + y/x = -1 , find the value of x^3 - y^3
marin [14]

Answer:

  0

Step-by-step explanation:

Multiplying the first equation by xy, we have ...

  x^2 +y^2 = -xy

Factoring the expression of interest, we have ...

  x^3 -y^3 = (x -y)(x^2 +xy +y^2)

Substituting for xy using the first expression we found, this is ...

  x^3 -y^3 = (x -y)(x^2 -(x^2 +y^2) +y^2) = (x -y)(0) = 0

The value of x^3 -y^3 is 0.
