No they would be intersecting. x=-1 is a vertical line down the x axis on -1. y=2 is a horizontal line at 2 on the y axis.

Hi! Your problem will be explained in the explanation section.

Furthermore, your answer is No, the given lines are not parallel.

Why? See below! Questions about my answer and explanation can be asked through comments! :)

Step-by-step explanation:

Hi there! Today I will be explaining these things which may benefit you.

  • Parallel Line
  • Perpendicular Line
  • Horizontal and Vertical Line

You might have known or heard these lines somewhere. <em>But what are they?</em>

<u>Parallel</u>

Parallel Lines are lines that do not intercept each others. They are same lines except they have distance. I think you might be confusing if I keep explaining. Let's look at an attachment instead. Please see <u>the first attachment</u> for how do parallel lines look like.

<u>Perpendicular</u>

Perpendicular Lines are lines that intercept each others. Both lines intercepting each others create a right angle around the interception. See <u>the second attachment</u> for how do perpendicular lines look like.

Next things are going to be main topic for our problem. <em>What is the difference between graph of x = -1 and y = 2?</em>

In the coordinate plane, graph of x-coordinate would be a straight vertical line because x = -1 isn't given any ranges. Therefore, x = -1 would have range as real number.

Similar to y = 2. y = 2 isn't given any domains. Therefore, y = 2 would have domain as real number and have a horizontal line graph.

A blind man wanders under a door into an empty room. After running into the walls repeatedly for a while, it stops to think and
Nostrana [21]

From the side where the man is located in the 10' by 12' rectangular room, we have;

A) 0.046

B) The average time to escape in first attempt is approximately 605.02 seconds

<h3>Which concept can be used to find the odds and time of escape?</h3>

A) From The given diagram, we have;

Width of the door = 10 - 6 - 2 = 2

Therefore, the door is 2 feet wide

Distance, d1, from the man to the side of the door closer to him is given by Pythagorean theorem as follows;

  • d1 = √(6² + 7²) = √(85)

From the furthest side of the door to the man, we have;

  • d2 = √(7² + 8²) = √(113)

According to the law of cosines, we have;

2² = 85+113 - 2×√(85)×√(113) cos(A)

Where angle <em>A </em>is the angle formed by the lines from the man to the closer and farther sides of the door.

2×√(85)×√(113) cos(A) = 85+113 - 2²

A = arccos((85+113 - 2²)/(2×√(85)×√(113)))

A = arccos (194/(2×√(9605)) ≈ 8.213°

The angle of the possible directions in which the man can turn is 180°.

Therefore;

The probability, <em>P(</em><em>E)</em>, of escaping in the first move is therefore;

  • P(E) = 8.213°/180° ≈ 0.046

B) Given that the man escapes in the first move, the shortest and longest distances the man moves are;

d1 = √(85) and d2 = √(113)

Speed of the man, <em>v </em>= 0.5 cm/sec

Therefore by unit conversion function of a graphing calculator;

  • v = (25/1524) ft./sec

The times taken are;

t1 = √(85)/(25/1524) ≈ 562.023

t2 = √(113)/(25/1524) ≈ 648.014.

Average time, <em>t </em>= (t1 + t2)/2

Which gives;

t = (562.023 + 648.014)/2 ≈ 605.02

The average time it takes the man to escape in first move is <em>t </em><em>≈</em> 605.02 seconds.

Need this asap! questions in the ss
svetlana [45]

Answer/Step-by-step explanation:

Part A:

Evidence 1: the line passes through the point of origin, (0, 0)

Evidence 2: it has a unit rate or constant of proportionality, k = y/x = 5/3

Part B:

When extended, if the ray passes through the point, (18, 30), then y/x of this point, should give us the same unit rate (k) of 5/3 of the graph.

Thus:

y/x = 30/18

Simplify

= 5/3

Thus, it has the same unit rate of the graph, therefore, the ray passes through the point (18, 30).

colleen rolls a number cube and flips a coin. What is the probabilty that she will roll at least a 3 or flip heads
anyanavicka [17]
The probability of her rolling at least a 3 and flipping heads is 4/12 or 33 1/3 %.  

4/6 * 1/2 = 4/12= 1/3 =0.3333333 = 33 1/3% or 33.33333%

I hope this helps!!
