Answer:
6840
Step-by-step explanation:
Here, the order matters (1st, 2nd, and 3rd), so we need to use permutations.
There are 20 people who can get in first place. After that, there are 19 people who can get in second place. Finally, there are 18 people who can get in third place. So:
20 * 19 * 18 = 6840
Answer:
-1/10 for first one and -4/2 for second one

lol can I have brainliest?
Answer: D
Step-by-step explanation:
It is a linear function and the slope is negative and the y intercept is negative.
In order for <em>F</em> to be conservative, there must be a scalar function <em>f</em> such that the gradient of <em>f</em> is equal to <em>F</em>. This means


Integrate both sides of the first equation with respect to <em>x</em> :

Differentiate both sides with respect to <em>y</em> :

But we assume <em>g</em> is a function of <em>y</em>, which means its derivative can't possibly contain <em>x</em>, so there is no scalar function <em>f</em> whose gradient is <em>F</em>. Therefore <em>F</em> is not conservative.
Answer:
y = -1.5x - 3
Step-by-step explanation:
The slope-intercept form of a line is y = mx + c where m is the slope of the line and c is the y-intercept of the line.
To find the slope of a line, you need to find the
between two of the points. I will be using the points (-2, 0) and (0, -3).
=
= 
= -1.5
Now based on the graph, we see that the y-intercept is -3. Thus, the entire equation of the given line is: y = -1.5x - 3
