Find the parametric equations for the line that passes through the point P (3,2,1) and is parallel to the vector v = (0,-4,2)

Answer:

(x,y,z) = (3, 2-4t, 1+2t)

Step-by-step explanation:

Given that a straight line passes through the point P(3,2,1)

Also given that the line is parallel to vector V = (0,-4,2)

This implies that the required line has direction ratios as (0,-4,2)

Hence in cartesian form we can represent the line as

\frac{x-3}{0} =\frac{y-2}{-4}=\frac{z-1}{2}=t

Here t is the parameter

In other words, any point on the line is represented parametrically as

(x,y,z) = (3, 2-4t, 1+2t)

In a dilatation for find the new coordinates we have to multiply the initial value for the the scale factor

A’(-3, 12)

B’(9,6)

C’(-9,-3)

so the general rule is:

(x,y) -> (3x, 3y)

wolverine [178]

Answer:

Step-by-step explanation:

Given that :

Dimension of each side = 3.5 feets by 11 feets

Area of each side :

Length * width = (3.5 * 11) feets = 38.5 ft²

Number of sides = 6

Hence, number of square feets to paint :

Number of sides * area of each side :

6 * 38.5 ft²

= 231 ft²
