Answer:

Using vector concepts, it is found that:

1. The horizontal component of the vector is 5.

2. The magnitude is of 14.87.

3. The vertical component of the vector is 2.

-------------

A vector (x,y) has x as horizontal component and y as vertical component.

The magnitude is  

Given two points, a vector is formed by the subtraction of the endpoint by the start point.

-------------

Item 1:

The horizontal component of the start is -3.

The horizontal component of the end is 2.

Thus, the horizontal component of the vector is  

-------------

Item 2:

Starts at (1,9), ends at (6,-5), thus, the coordinates are:

The magnitude is:

The magnitude is of 14.87.

Item 3:

The vertical component of the start is -10.

The vertical component of the end is -8.

Thus, the vertical component of the vector is

Answer:

  27 minutes

Step-by-step explanation:

The relevant relations are ...

  1 min = 60 s

  1 km = 1000 m

  time = distance/speed

__

  time = (8.1 km)×(1000 m)/(1 km)/(5 m/s)×(1 min/(60 s))

  = (8.1×1000)/(5×60) min = 27 min

It takes 27 minutes to cover 8.1 km at a speed of 5 m/s.

Answer:

250 $3 tickets and 100 $2 tickets were sold.

Step-by-step explanation:

The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?

Solution:

Step 1: Set up a table with quantity and value.

quantityvaluetotal$3 tickets$2 ticketstogether

Step 2: Fill in the table with information from the question.

The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?

Let x = number of $3 tickets

Let y = number of $2 tickets

Total = quantity × value

quantityvaluetotal$3 ticketsx33x$2 ticketsy22ytogether350950

Step 3: Add down each column to get the equations

x + y = 350                    (equation 1)

3x + 2y = 950                (equation 2)

Use Substitution Method

Isolate variable x in equation 1

x = 350 – y                     (equation 3)

Substitute equation 3 into equation 2

3(350 – y) + 2y = 950

1050 – 3y + 2y = 950

3y – 2y = 1050 – 950

y = 100

Substitute y = 100 into equation 1

x + 100 = 350

x = 250

7.75J

Step-by-step explanation:

kinectic energy formula = 1/2mv²

m mass

v velocity

1/2 x 62 x 0.5² = 7.75

A woman is walking at a rate of 0.5m/s. Her mass is 62 kg. The woman's kinetic energy in joules:

K.E. = 7.75 kgm²/s²

What is Kinetic Energy?

The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

Given,

Mass = 62kg

Velocity = 0.5m/s

The formula for Kinetic Energy is :

K.E. = 1/2 m v².

K.E. = 1/2 (62)(0.5)²

K.E. = 1/2 (62)(0.25)

K.E. = 1/2 (15.5)

K.E. = 15.5/2

K.E. = 7.75 kgm²/s²

or

K.E. = 7.75 joules

Hence, he woman's kinetic energy in joules, K.E. = 7.75 kgm²/s²

Answer:

  4x +y = -1

Step-by-step explanation:

The equation of the perpendicular line can be written by ...

The x- and y-coefficients in the given equation are 1 and -4, respectively. Since we want the leading coefficient positive, it is convenient to use 4 and 1 as the coefficients in the new equation. The constant can be found by substituting (x, y) = (-2, 7) to see what it is.

  4x +y = 4(-2) +7 = -1

The desired perpendicular line has an equation ...

According to the question given,

[tex]\sf\longmapsto \: emigrants=-5000[/tex]

[tex]\sf\longmapsto \: Immigrants = 100000[/tex]

[tex]\sf\longmapsto \: Death -350000[/tex]

[tex] \sf \longmapsto \: Birth=600000[/tex]

Now let's solve out and get the result!

The change of population:

[tex] \sf \longmapsto600000-350000 + 100000 - 5000=350000[/tex]

The total population at the end of the year:

[tex]\sf\longmapsto \:2000000 + 350000 [/tex]

[tex]\sf\dashrightarrow2350000[/tex]

At the end of the year, the population will be 20,345,000.

The rate of change in population is 1.75%.

Rate is a measurement to determine the change in one quantity with respect to another quantity.

The given information are,

Total population of the country initially = 20,000,000

Total number of births during the year = 600,000

Total number of deaths during the year = 350,000

Number of immigrants = 100,000

And number of emigrants = 5,000

The population at the end of the year

= 20,000,000 + 600,000 - 350,000 + 100,000 - 5,000

= 20,345,000

At the end of the year the population will be 20,345,000.

The increase in population  = 20,345,000 - 20,000,000

                                              = 345,000

the rate of increasing = 345000/20000000)x100  = 1.75%

The rate of change per year is 1.75%.
