Find the parametric equations for the line that passes through the points P (1,1,0) and Q (0,2,2).

sp2606 [1]

Answer:

The parametric equations for the given line are x=1-t, y=1+t and z=2t.

Step-by-step explanation:

Given information: P (1,1,0) and Q (0,2,2).

The parametric equation of line are

$x=x_0+at$

$y=y_0+bt$

$z=z_0+ct$

where, $(x_0,y_0,z_0)$ is point on line and <a,b,c> is direction vector.

The line passes through the points P (1,1,0) and Q (0,2,2). So, the direction vector is

$\overrightarrow{v}=$

The direction vector is <-1,1,2>. So, a=-1, b=1 and c=2. The parametric equation of line are

$x=1+(-1)t=1-t$

$y=1+(1)t=1+t$

$z=0+(2)t=2t$

Therefore the parametric equations for the given line are x=1-t, y=1+t and z=2t.

Please help!<br> Thanks<br> BRIANLIEST OF 2 PPL ANSWER

vlada-n [284]

Answer:

PS = 7

k = 9

Step-by-step explanation:

RS = PQ Given

3x - 7 = x - 1 Substitute algebraic terms. Subtract x from both sides

3x-x - 7 = x - 1 - x Combine

2x - 7 = - 1 Add 7 to both sides.

2x - 7+7 = -1+7 Combine

2x = 6 Divide by 2

2x/2 = 6/2

x = 3

Length of PS = x - 1 + x + 3x - 7

Length of PS = 5x - 8

Length of PS = 5*3 - 8

Length of PS = 7

=========================

f(x) = k - x^2

x = 2

f(x) = 5 is the given point

5 = k - x^2 Substitute for x^2

5 = k - 2^2 Expand

5 = k - 4 Add 4 to both sides.

5+4=k-4+4 Combine

k = 9
