Answer:

The speeds are 74 mph and 87 mph.  

Step-by-step explanation:

Let x = speed of slower train

     x + 13 = speed of faster train

 

The trains meet when the sum of the distances = 483

 

3x + 3(x+13) = 483

 

6x + 39 = 483

 

6x = 444

 

 x = 74 mph

 

The speeds are 74 mph and 87 mph.

Step-by-step explanation:

6. The fraction can be written as;

\frac{x^2}{2y} /\frac{y^2}{4} \\\\\frac{x^2}{2y} *\frac{4}{y^2} \\\\

Divide 4 by 2

=\frac{2x^2}{y^3}

7.

The fraction can be written as;

\frac{b^2}{6} /\frac{b}{a}

introduce product sign as

\frac{b^2}{6} *\frac{a}{b} \\\\=b*a/6\\=\frac{ab}{6}

8.

The fraction can be written as;

\frac{x}{y} /\frac{yx}{2}

Introduce product sign

\frac{x}{y} *\frac{2}{yx} \\\\=\frac{2}{y^2}

9.

The fraction can be written as;

\frac{x}{y^2} /\frac{x}{y} \\\\\\=\frac{x}{y^2} *\frac{y}{x} \\\\\\=\frac{1}{y}

10.

The fraction is simplified to;

\frac{x}{3y} /\frac{9}{x} \\\\\\\frac{x}{3y} *\frac{x}{9} =\frac{x^2}{27y}

Solve x'=5t(sqrt(x)) x(0)=1
LekaFEV [45]

Answer:

2\sqrt{x}=\frac{5t^2}{2}+2

Step-by-step explanation:

Given: \frac{\mathrm{d} x}{\mathrm{d} t}=5t\sqrt{x}\,,\, x(0)=1

Solution:

A differential equation is said to be separable if it can be written separately as  functions of two variables.

Given equation is separable.

We can write this equation as follows:

\frac{dx}{\sqrt{x}}=5t\,dt

On integrating both sides, we get

\int \frac{dx}{\sqrt{x}}=\int 5t\,dt

Formulae Used:

\int \frac{1}{\sqrt{x}}=2\sqrt{x}\,\,,\,\,\int t\,dt=\frac{t^2}{2}

So, we get solution as 2\sqrt{x}=\frac{5t^2}{2}+C

Applying condition: x(0) = 1, we get C=2

Therefore, 2\sqrt{x}=\frac{5t^2}{2}+2
