Answer:

The change in momentum between 0 ms and 14 ms is 0 kg•m/s

Step-by-step explanation:

Here, we want to calculate the change in momentum using the graphical illustration

This is same as the slope using the two points

Let us have 2 expressions of (x,y)

Mathematically, that will be obtained from the graph as follows;

At 0 ms, we have 0 N

At 14 ms , we also have 0

So the two points we are considering are;

(0,0) and (14,0)

= (0-0)/(14-0) = 0/14 = 0 N/ms

Answer:

Part 1) solution {(-5,8),(3,0)} ----> $y+12=x^{2}+x$ and $x+y=3$

Part 2) No solutions ----> $y-15=x^{2}+4x$ and $x-y=1$

Part 3) solution [(-2,5),(3,-5)] ---> $y+5=x^{2}-3x$ and $2x+y=1$

Part 4) No solutions ---> $y-6=x^{2}-3x$ and $x+2y=2$

Part 5) solution [(2,3),(8,9)] ---> $y-17=x^{2}-9x$ and $-x+y=1$

Part 6) solution [(-2,3),(7,-6)] ---> $y-15=-x^{2}+4x$ and $x+y=1$

Step-by-step explanation:

Part 1) we have

$y+12=x^{2}+x$ ----> equation A

$x+y=3$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution are the points (-5,8) and (3,0)

see the attached figure N 1

Part 2) we have

$y-15=x^{2}+4x$ ----> equation A

$x-y=1$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The system has no solutions, because there is no point of intersection between the two graphs

see the attached figure N 2

Part 3) we have

$y+5=x^{2}-3x$ ----> equation A

$2x+y=1$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution are the points (-2,5) and (3,-5)

see the attached figure N 3

Part 4) we have

$y-6=x^{2}-3x$ ----> equation A

$x+2y=2$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The system has no solutions, because there is no point of intersection between the two graphs

see the attached figure N 4

Part 5) we have

$y-17=x^{2}-9x$ ----> equation A

$-x+y=1$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution are the points (2,3) and (8,9)

see the attached figure N 5

Part 6) we have

$y-15=-x^{2}+4x$ ----> equation A

$x+y=1$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution are the points (-2,3) and (7,-6)

see the attached figure N 6

Write the equation of the function<br> please help

Andrej [43]

Examine the graph.

The graph looks like one of square-root....let's see.

If we make a translation of (-3,-2), i.e. the beginning of the graph, to the origin, we will see that we have the following points on the graph,

(0,0), (1,1), (4,2), (5,2.2), (8,2.8)

all of which correspond to the sqrt(x) function.

Thus if we take the parent graph as sqrt(x), and translate to the current position by a translation of (-3,-2), we get the current graph.

To do the translation, we recall that a translation of a parent function f(x) by (h,k) can be effected by

g(x) ->f(x-h)+k

Setting h=-3, k=-2, and f(x)=sqrt(x), we get

current graph g(x)=f(x-(-3)+(-2)=f(x+3)-2 = sqrt(x+3)-2

Three times b less than 100 is equal to the product of 6 and b

Irina-Kira [14]

Not exactly sure which equation you meant:

3(100-b)=6b
300-3b=6b
300=9b
b= about 33

100-3b=6b
100=9b
b=about 11
