What does the phrase rise over run refer to when defining slope

1 answer:

4 0

I just learned this. Rise over run is also rise divided by run. The rise refers to the y axis (since y is vertical so it's rising), and run refers to the x axis (Since x is horizontal so it's running straight). So in other words, rise/run = y/x. To calculate the slope, you do y/x. For example, if you have y=3 and x=8, then your slope is 3/8. To plot that on a graph, you start from your point, and go up three, and across 8. Hope this helps.

The legend of King Arthur is well-known in literature. Based on Unsolved Mysteries of History, there is little to suggest it is true. Do you think it is important for people to believe in legends like King Arthur even if there is little evidence to support them? Why or why not? Write a short (3 paragraphs) explanatory essay stating your opinion. Justify your opinion and conclusions with relevant textual evidence (quotes or paraphrased ideas from sources) and background knowledge. Remember to use relevant vocabulary from the text in your essay.l

As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens th

MA_775_DIABLO [31]

Answer:

Watermelon is going at a speed of $13.33\ \rm m/s$ in downward direction

Explanation:

Given

Height of the Empire State building = 320 m
Speed of the superman = 24 m/s

since both the motion of both watermelon and the superman is under gravity. The acceleration of both is g in downwards direction. So the relative acceleration between them is zero and when they meet the relative distance covered by them will be the height of the Empire State building.

so let t be the time when they meet given by

$\dfrac{320}{24}\\t=13.33\ \rm s$

Now let v be the velocity of the the watermelon when they meet given by

$v=gt\\v=9.8\times13.33\\v=130.63\ \rm m/s$

What is parallelogram law of vector addition ???

Vladimir [108]

Answer:

According to the parallelogram law of vector addition if two vectors act along two adjacent sides of a parallelogram(having magnitude equal to the length of the sides) both pointing away from the common vertex, then the resultant is represented by the diagonal of the parallelogram passing through the same common vertex

Calculate change in height of a 2kg ball moving a speed of 10m/s up a frictionless ramp until it stops

Nataliya [291]

The change in the height of the object is 5.1 m.

<h3>Conservation of mechanical energy</h3>

The principle of conservation of mechanical energy states that the total energy of an isolated system is always conserved.

The change in the height of the object is calculated by applying the principle of conservation of mechanical energy as follows;

P.E = K.E

$mg \Delta h = \frac{1}{2} mv^2\\\\g \Delta h = \frac{1}{2}v^2\\\\\Delta h = \frac{v^2}{2g} \\\\\Delta h = \frac{(10)^2}{2(9.8)} \\\\\Delta h = 5.1 \ m$

Thus, the change in the height of the object is 5.1 m.
