Answer:

The matrix A) shows the change in prices from 1995 to 2005.

Step-by-step explanation:

From the given matrices it can be seen that prices have decreased.

The change is negative Δp < 0 Δp= pH - pF

Given matrices are the same type ( 3x2 ) = (number of rows x number of columns ) so they can be subtracted.

Matrices are subtracted by subtracking their corresponding elements, i.e. elements in the same positions.

When we subtracted matrix F from matrix H we get matrix    A).

Good luck!!!

A car of 1000 kg starts to move from rest and travels a distance of 150 m in 10 second. How much force is needed?​
allsm [11]
  • Initial velocity=u=0m/s
  • Distance=s=150m
  • Time=t=10s
  • Acceleration=a

Using second equation of kinematics

\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2

\\ \sf\longmapsto 150=0(10)+\dfrac{1}{2}a(10)^2

\\ \sf\longmapsto 150=\dfrac{1}{2}\times 100a

\\ \sf\longmapsto 50a=150

\\ \sf\longmapsto a=\dfrac{150}{50}

\\ \sf\longmapsto a=3m/s^2

  • Mass=m=1000kg
  • Force=F

Using newtons second law

\\ \sf\longmapsto F=ma

\\ \sf\longmapsto F=1000(3)

\\ \sf\longmapsto F=3000N

A) \frac{2 \frac{1}{4}}{ \frac{1}{2}}
b)\frac{1}{2} • 2 = 1
so \frac{9}{4} • 2 = \frac{9}{2} cups (which is 4 \frac{1}{2} )

juin [17]
Summary of problem.
annual production = 60000 units
work hours per worker = 200*12=2400 hours
productivity = 0.15 unit / person-hour
Need to calculate the number of workers/persons employed.
 
Each unit requires 1 unit / 0.15 unit/person-hour
= 1/0.15 person-hours / unit

60000 unit requires 60000 units * 1/0.15  person-hours/unit
= 400000 person-hours

400000 person-hours requires 400000 person-hours /2400 hours = 166.7 persons 
=>
The plant has 167 labourers  (assuming perfect attendance).
