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.
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.
Answer:
The average acceleration of train is
Step-by-step explanation:
We have,
A train that slows down from 15 m/s to 8.6 m/s in 1.2 s. It means that 15 m/s is its initial velocity and 8.6 m/s is its final velocity.
It is required to find the average acceleration of the train.
The average acceleration of train is . Negative signs shows that the train is decelerating.
Based on the knowledge of <em>trigonometric</em> expressions and properties of <em>trigonometric</em> functions, the value of the <em>sine</em> function is equal to - √731 / 30.
<h3>How to find the value of a trigonometric function</h3>Herein we must make use of <em>trigonometric</em> expressions and properties of <em>trigonometric</em> functions to find the right value. According to trigonometry, both cosine and sine are <em>negative</em> in the <em>third</em> quadrant. Thus, by using the <em>fundamental trigonometric</em> expression (sin² α + cos² α = 1) and substituting all known terms we find that:
sin θ ≈ - √731 / 30
Based on the knowledge of <em>trigonometric</em> expressions and properties of <em>trigonometric</em> functions, the value of the <em>sine</em> function is equal to - √731 / 30.
