For the lines x=3t, y=1-2t, z=2-3t and x (3, 1, 4) +s(-9, 6, 9) (a) Show that the lines are parallel. (b) Calculate the distance

son4ous [18]

Answer:

Step-by-step explanation:

Given lines in parametric form

line $L_1$

$\frac{x}{3}=\frac{y-1}{-2} =\frac{z-2}{-3}$

direction vector of $L_1 v_1=$

Line $L_2$

direction vector of $L_2 v_2=$

therefore

$v_2=-3v_1$

thus lines are parallel.

(ii)distance between two lines is

$L_2$ is given by

$\frac{x-3}{-9}=\frac{y-1}{6} =\frac{z-4}{9}$ =s

$\frac{x-3}{-3}=\frac{y-1}{2} =\frac{z-4}{3}$ =3s

$\left | \frac{\begin{vmatrix}x_2-x_1 &y_2-y_1 &z_2-z_1 \\ a_1&b_1&c_1 \\ a_2&b_2&c_2\end{vmatrix}}{\sqrt{\left ( a_1b_2-a_2b_1 \right )^2+\left ( b_1c_2-b_2c_1 \right )^2+\left ( c_1a_2-c_2a_1 \right )^2}}\right |$

where $a_1$ =3

$b_1$ =-2

$c_1$ =-3

$a_2$ =-9

$b_2$ =6

$c_2$ =9

distance(d)=0 units since value of the matrix

$\begin{vmatrix}x_2-x_1 &y_2-y_1 &z_2-z_1\\ a_1&b_1&c_1 \\a_2&b_2 &c_2 \end{vmatrix}$

is zero

Answer:

x = 12

y = 4√10

z = 12√10

Step-by-step explanation:

The geometric mean rules apply. Each of the segments labeled with a letter is the geometric mean of the segments it touches on the hypotenuse.

x = √(4×36) = 12

y = √(4×(4+36)) = 4√10

z = √(36×(36+4)) = 12√10

HELPPPP!!!!! MATH!!!! PLZ!!!!!

MariettaO [177]

Answer:

Y=5x

Step-by-step explanation:

Y=mx+b, or y=rise/run+starting value

as there is no starting value, we would simply add no variable

rise/run in this equation would 5/1 because when it rises 5, it goes right 1, simplifying that would be 5

300=x^2+15x what is x?

Vlada [557]

Answer:

x = -26.3746, 11.3746

Step-by-step explanation:

Easiest and fastest way to solve for <em>x</em> is to graph x² + 15x - 300 and analyze where the graph crosses the x-axis.

Alternatively, you can use the Quadratic Formula to help solve for <em>x</em>.
