Determine the equation of a line that is parallel to the line 2x - 3y = 12 and

zvonat [6]

Answer:

y=2/3x-6

Step-by-step explanation:

2x - 3y = 12

2x-12=3y

3y=2x-12 /:3

y=2/3x-12/3

y=2/3x-4

Slope=2/3

The line are parallel so the slope is the same.

(9,0).. x1 =, y1 =0

y-y1=2/3(x-x1)

y-0=2/3(x-9)

y=2/3x-2/3*9

y=2/3x-6

Let the vector \mathbf{v}v have an initial point at (-5, -5)(−5,−5) and a terminal point at (-3, 1)(−3,1). Determine the compone

Ostrovityanka [42]

Answer:

The components of the vector are $x = 2$ and $y = 6$ , respectively.

Step-by-step explanation:

The components of the vector is equal to the vector position of the terminal point relative to the initial point ( $\vec v$ ), that is:

$\vec v = B(x,y) - A(x,y)$ (1)

Where:

$A(x,y)$ - Initial point.

$B(x,y)$ - Terminal point.

If we know that $A(x,y) = (-5,-5)$ and $B(x,y) = (-3,1)$ , then the vector is:

$\vec v = (-3,1) -(-5-5)$

$\vec v = (2, 6)$

The components of the vector are $x = 2$ and $y = 6$ , respectively.

6. If X is the midpoint of WY, WX = 3x - 1 and<br> WY = 10x - 26, find XY.

Dennis_Churaev [7]

XY = 17

Step-by-step explanation:

It is given that x is the mid-point of WY, so it divides WY in two equal parts

WX and XY so the sum of both lengths will constitute the length of WY

$WY = WX+XY\\XY = WY - WX$

putting values

$XY = 10x-26 -(3x-1)\\= 10x-26-3x+1\\= 7x-25$

As X is the mid-point,

$WX = XY\\3x-1 = 7x-25\\3x-1-3x = 7x-25-3x\\-1 = 4x-25\\-1+25 = 4x-25+25\\24 = 4x$

Dividing both sides by 4

$\frac{4x}{4} = \frac{24}{4}\\x = 6$

XY = 7x-25

$=7(6) -25\\= 42-25\\=17$

So,

XY = 17

<u>Verification:</u>

WX = XY

$3x-1 = 7x-25\\3(6)-1 = 7(6)-25\\18-1 = 42-25\\17 = 17$

Find the arc length of the semicircle. Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi an

DedPeter [7]

Answer:

$3.14r$ or $\pi r$

Step-by-step explanation:

Given:

A semicircle.

To find:

Arc length of the semicircle = ?

Solution:

Formula for angle subtended by an arc on the center of circle is given as:

$\theta = \dfrac{l}{r}$

where $l$ is the arc length and

$r$ is the radius of semicircle.

Angle of full circle is $2\pi$

So, angle of semicircle = $\pi$

Using the formula, we can see that:

$l = \theta \times r$

$\Rightarrow l = \pi \times r\\\\OR\\\Rightarrow l = 3.14r$

So, the answer is:

Arc Length of semicircle = $3.14r$ or $\pi r$
