The masses mi are located at the points Pi. Find the moments Mx and My and the center of mass of the system. m1 = 4, m2 = 3, m3
viva [34]

Answer:

M_x= 8

M_y = 6

Therefore the co-ordinate of the center of mass is = (\frac{4}{5},\frac{3}{5})

Step-by-step explanation:

Center of mass: Center of mass of an object is a point on the object. Center of mass is the average position of the system.

Center of mass of a triangle is the centriod of a triangle.

Given that m₁= 4, m₂=3, m₃=3 and the points are P₁(2,-3), P₂(-3,1) and P₃(3,5)

M_x = ∑(mass × x-co-ordinate)

M_y = ∑(mass × y-co-ordinate)

Therefore  

M_x = (4×2)+{3×(-3)}+(3×3)

     =8

M_y = {4×(-3)}+{3×1}+(3×5)

    =6

The x co-ordinate of the center of mass is the ratio of M_x to the total mass.

The y co-ordinate of the center of mass is the ratio of M_y to the total mass.

Total mass (m) = m₁+ m₂+ m₃

                        = 4+3+3

                        =10

The x co-ordinate of the center of mass is \frac {8}{10} = \frac {4}{5}

The y co-ordinate of the center of mass is \frac{6}{10}=\frac{3}{5}

Therefore the co-ordinate of the center of mass is = (\frac{4}{5},\frac{3}{5})

What is the slope of the line shown below? (enter your answer as a decimal if necessary.)
maksim [4K]

Answer: The slope is 2 -Please mark brainliest

1. Find the X and Y values of each point

X1: 1

X2: -1

Y1: 3

Y2: -1

2. Subtract X1 from X2 and Y1 from Y2

Y: -1-3=-4

X: -1-1=-2

3. Divide the X value by the Y value

-4/-2=2

The slope of the line shown on the coordinate plane is 2.

Which is better: having a stock that goes up 30% on Wednesday than drops 20% on Thursday, or a stock
finlep [7]

Step-by-step explanation:

  • If the stock goes up 30%, it's multiplied by 1.3.

The reason is that  x + .3 \times x=1.3\times x

  • If the stock goes down 20%, it's multiplied by 0.8

The reason is that x - .2 \times x = 0.8 \times x

  • If the stock goes down 30%, it's multiplied by 0.7

The reason is that x - .3 \times x = 0.7 \times x

  • If the stock goes up 40%, it's multiplied by 1.4.

The reason is that  x + .4 \times x=1.4\times x

So

If you increase it by 30% and then drop it by 20%, it means you are multiplying it by 1.3 and then multiplying it by .8. In other words:

1.3 \times 0.8=1.04

So, the net gain is = .04

Assume the original value = 500

Increase it by 30% and it becomes 650

Decrease 650 by 20% and it becomes 520

So, the net gain = 20

Verification:

500 \times .04=20

And

If you drop it by 30% and then increase it by 40%, you are multiplying it by .7 and then multiplying it by 1.4. In other words:

.7 \times 1.4=0.98

So, the net loss is = 1 - 0.98 = .02

Assume the original value = 500

Decrease it by 30% and it becomes 350.

increase 350 by 40% and it becomes 490.

So, the net loss is = 10

Verification:

500 \times .02=10

Keywords: stock, loss, gain
