Applying Newton's Second Law, it is found that the force, in Newtons, is given by:
![F = 10[v(21) - v(16)]](https://tex.z-dn.net/?f=F%20%3D%2010%5Bv%2821%29%20-%20v%2816%29%5D)
Newton's Second Law states that Force, in Newtons, is <u>mass times acceleration</u>, that is:
In this problem, mass of 50 kg, thus 
Acceleration is <u>change in velocity divided by change in time</u>, that is:
In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:
Thus, the force is given by:
![F = 50\frac{[v(21) - v(16)]}{5}](https://tex.z-dn.net/?f=F%20%3D%2050%5Cfrac%7B%5Bv%2821%29%20-%20v%2816%29%5D%7D%7B5%7D)

No x-intercept/zero
Step by step
To find x-intercept/zero, substitute f(x)=0
F(x)=-20
0=-20
The statement is false for any value of
X=0
Since there is no solution for f(x)=0, there is no -intercept/Zero
Your welcome:)
The function given is a line with one zero at the center (0,0)
<u>Answer:</u>
$142500
<u>Step-by-step explanation:</u>
We are given that the resident of a certain University receives a salary that is three times the salary of one of the department heads.
Assuming 
to be the salary of the department head, if the total of the two salaries is $190000, we are to find the salary of the president of the University.
We can write an equation in terms of :
Salary of the president of the University = 
= $142500
Answer:
y = 5x - 5
Step-by-step explanation:
It appears that the graph intersects the y-axis at (0, -5). This point is the y-intercept of the line.
As we move from (0, -5) to the point (2, 5), x increases by 2 and y increases by 10. Thus, the slope of the line through these two points is
m = rise / run = 10 / 2 = 5.
The slope-intercept form of the equation of a straight line, y = mx + b, becomes y = 5x - 5
