Find a vector that is parallel to -9x+2y = 10. Please explain step by step

coldgirl [10]

Answer:

Step-by-step explanation:

Step One: Find the slope of the given Line

2y - 9x = 10 Add 9x to both sides

2y - 9x + 9x = 9x + 10 Combine

2y = 9x + 10

y = 9/2 x + 5

The parallel line has a slope of 9/2

Step Two: Find the magnitude

sqrt(x^2 + y^2) = r You don't have a magnitude. Invent one, r

x^2 + y^2 = r^2 Both sides have been squared

Step Three: Find the change in y / x

y / x = 9/2

Step Four: Find the value of y

y/x = 9/2 Multiply both sides by x

y = 9/2 * x

Step Five: Solve for x

x^2 + y^2 = r^2

x^2 +(9/2x)^2 = r^2

x^2 + 81x^2 / 4 = r^2 Change the 1 to common denominator 1 = 4/4

4/4 x^2 + 81x^2/ 4 = r^2

85 x^2/ 4 = r^2 Multiply both sides by 4/85

4/85 * (85 / 4) x^2 = 4/85 r^2

x^2 = 4/85 r^2 Take the square root of both sides

x = +/- 2/sqrt(85) r Rationalize the denominator

x = (+/- 2 sqrt(85) ) / 85 *

Step Six: Solve for y

y = 9/2 x

y = 9/2 * 2 sqrt(85) / 85 Cancel the 2s

y = +/- 9* sqrt(85)/85

Answer

<2*sqrt(85)/85 , 9 sqrt(85)/85>

You can write the minus answer if you need it. I kind of suspect you won't.

Micheal runs 8m, South then turns around and runs 12m North. what is the distance and displacement covered?

Dmitriy789 [7]

Answers:

Distance = 20 meters
Displacement = 4 meters North

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

Explanation:

To find the distance traveled, we add the two values to get 8+12 = 20 meters.

------------

For the displacement, I recommend drawing a vertical number line. Mark the values 0, -8 and 4 on the number line. Going from 0 to -8 represents going 8 meters south. From -8, move up 12 units and you should arrive at 4 on the number line, which represents being 4 meters north of the original position 0. The displacement only cares about the start and end points, more specifically, the change between the two. The direction is also important for the displacement.

In other words, Michael started at 0, did a bunch of movements, and ended up at 4 on the number line. So we can simplify all those movements to one single movement of "move north 4 meters" to represent the displacement.

As you can see, it's possible to get a displacement of 0 meters, which is not the case for the distance traveled in the previous section.

35 POINTS!!! The measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x. Write an equation that would al

Marina86 [1]

Answer:

The value of x is 40.

Step-by-step explanation:

The measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x.

According to the angle sum property of quadrilateral, the sum of interior angles of a quadrilateral is always 360 degree.

Since the measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x, therefore

$x+2x+3x+3x=360$
