Find parametric equations and symmetric equations for the line. (Use the parameter t.) The line through (3, 1, 0) and perpendicu

iren2701 [21]

Answer with Step-by-step explanation:

We are given that a point (3,1,0)

Two vectors are

A=<1,1,0>

B=<0,1,1>

$A\times B=\begin{vmatrix}i&j&k\\1&1&0\\0&1&1\end{vmatrix}$

$A\times B=i-j+k$

Let v $=A\times B=i-j+k$

$v==$

$r_0==$

$r=r_0+vt$

Substitute the values then we get

$r=+t$

$r=$

The parametric equation of the line

$x=x_0+at,y=y_0+bt,z=z_0+ct$

Using the formula

The parametric equation of the line which is passing through the point (3,1,0) and perpendicular to both i+j and j+k is given by

$x=3+t,y=1-t,z=t$

The symmetric equation of the line is given by

$\frac{x-x_0}{a}=\frac{y-y_0}{b}=\frac{z-z_0}{c}$

Using the formula

The symmetric equation of the line which is passing through the point (3,1,0) and perpendicular to both i+j and j+k is given by

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

Robin is a competitive archer. Her average arrow is within 6.5 cm of the center of the bullseye. John, Robin's trainer, keeps cl

polet [3.4K]

Answer:

Arrow C.

Step-by-step explanation:

Out of three arrows, nearest arrow from the origin will be the best arrow.

Ordered pair for arrow A → (-5, 4)

Distance between A and bullseye = $\sqrt{(y_{2}-y_{1})^2+(x_{2}-x_{1})^2}$

= $\sqrt{(0+5)^2+(0-4)^2}$

= $\sqrt{41}$

= 6.40 units

Ordered pair for arrow B → (5, -5)

Distance between B and bullseye = $\sqrt{(0-5)^2+(0+5)^2}$

= $5\sqrt{2}$

= 7.1 units

Ordered pair for arrow C → (-2, -6)

Distance between C and the bullseye = $\sqrt{(0+2)^2+(0+6)^2}$

= $\sqrt{40}$

= 6.32 units

Distance between C and the bullseye is the shortest.

Therefore, arrow C will be the best arrow.
