Answer:

$y = Ke^{5.2t}$

Exponential growth

Step-by-step explanation:

We can solve this differential equation by the separation of variables method.

We have that:

$\frac{dy}{dt} = 5.2y$

$\frac{dy}{y} = 5.2dt$

Integrating both sides

$\ln{y} = 5.2t + K$

In which K is the value of y when t = 0.

We apply the exponential to both sides, so:

$y = Ke^{5.2t}$

This is our exponential equation. Since the power of e is a positive value, the function represents exponential growth.

Answer:

x + y = 15

y = 3x + 1.5

x + (3x + 1.5) = 15

Step-by-step explanation:

Let :

Soft ball practice = x

Soccer practice = y

y = 3x + 1.5

Total practice time :

x + y = 15 - - - (1)

x + 3x + 1.5 = 15

4x + 1.5 = 15
