Answer:

Using vector concepts, it is found that:

1. The horizontal component of the vector is 5.

2. The magnitude is of 14.87.

3. The vertical component of the vector is 2.

-------------

A vector (x,y) has x as horizontal component and y as vertical component.

The magnitude is  

Given two points, a vector is formed by the subtraction of the endpoint by the start point.

-------------

Item 1:

The horizontal component of the start is -3.

The horizontal component of the end is 2.

Thus, the horizontal component of the vector is  

-------------

Item 2:

Starts at (1,9), ends at (6,-5), thus, the coordinates are:

The magnitude is:

The magnitude is of 14.87.

-------------

Item 3:

The vertical component of the start is -10.

The vertical component of the end is -8.

Thus, the vertical component of the vector is

On an architect's drawing of a house, 1 inch represents 7 feet. If the bedroom window is 5 inches long on the drawing, how long
Pavel [41]
We can use ratios here. The real size would have to be proportional, meaning that if I increase the line on the drawing 5 times, the real size would have to increase 5 times as well.

We can obviously see, after having said that, that the real window would have to be 35ft long (because we multiplied 1 inch by 5, and if 1 inch represents 7 feet, then we also have to multiply that by 5 so it’s proportional, and 7*5=35)

We can check too — 1 in : 7 ft = 5 in : x ft

x = (7ft * 5in) / 1in — we would get the same result :)

Answer:

\frac{2x - 5}{x + 5}

Step-by-step explanation:

Firstly, you have to factorize the expressions on the numerator and denorminator :

Numerator :

2 {x}^{2}  - 3x - 5

= 2 {x}^{2}  + 2x - 5x - 5

= 2x(x + 1) - 5(x + 1)

= (2x - 5)(x + 1)

Denorminator :

{x}^{2}  + 6x + 5

=  {x}^{2}  + x + 5x + 5

= x(x  +  1) + 5(x  + 1)

= (x  +  1)(x + 5)

Next, you have to put the factorized-form in the fraction and cut out the similar expressions :

\frac{(2x - 5)(x + 1)}{(x + 1)(x + 5)}

=  \frac{2x - 5}{x + 5}
