The real life application of coordinate plane are ; Digital, location in airports, Map projection, GPS, Latitude and Longitude and many more.

A coordinate plane is a tool used for graphing points, lines, and other objects.

Some real life applications are:

Digital World

In this, any PDF file we open are created according to 2-D coordinates (x, y), all the concepts like distances, slopes and trigonometry are applicable in this.

Location of Air Transport

In this, air traffic are mainly managed by coordinates study, to find the location of a particular location for any change in location of a plane it is used.

Map Projections

The points usually provides the frame of references for your data, to locate the position on the surface of earth.

GPS

We use GPS for any specific location identifier on the earth which we get in the form of coordinates, these are points showing the asked location.

Latitude and Longitude

These are the parameter used to locate any specific point on the earth, Latitude and Longitude are always defined by a point, they constitute a coordinates system to identify any geographical location.

Step-by-step explanation:

m * 2 = 38

Equation: 2m = 38

Solution:

2m = 38

 m = 38/2

m = 19

Malik's score = 19

Answer:

38 is the product of Malik's score and 2. Use the variable m to represent Malik's score

Marks scored by Malik

The equation will be

[tex] \frak{2m = 38}[/tex]

Total marks

[tex] \tt \: m \: = \dfrac{38}{2} [/tex]

[tex] \tt \: m \: = 19[/tex]

The marks scored by Malik is 19

Answer:

  5.0 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relevant relationship.

  Sin = Opposite/Hypotenuse

  sin(38°) = x/8.2

  x = 8.2·sin(38°) ≈ 5.048

  x ≈ 5.0 . . . . feet

Properties of Exponential Function for Roots.

[tex]a^{\frac{m}{n}}=\sqrt[n]{a^m}[/tex]

The first one is wrong as 4^1/2 would equal √4 = 2

The second choice is correct.

The third choice is correct because ∛8 = 2 and √4 also = 2

The fourth choice is wrong because √8 = 2√2

The fifth choice is also wrong because 2^1/2 would be √2 while √32 is 2^5

The sixth choice is 3^3/2 which would equal √27 = 3√3 which is correct.

Answer:

( x + 5 ) · ( x + 1 )

Step-by-step explanation:

-Factoring by grouping-

First, split the middle term into two parts that are factorable by the other variables.

x² + x + 5x + 5

Factor the parts

x · ( x + 1 ) + 5 · ( x + 1 )

( x + 5 ) · ( x + 1 )

Answer:

C

Step-by-step explanation:

Given

x² + 6x + 5

Consider the factors of the constant term (+ 5) which sum to give the coefficient of the x- term (+ 6)

The factors are + 1 and + 5 , since

1 × 5 = + 5 and 1 + 5 = + 6, thus

x² +6x + 5 = (x + 1)(x + 5) → C

Answer:

Joey completed 52 pushups each day.

Step-by-step explanation:

We know that he did 1,456 pushups in 4 weeks, and that there are 7 days a week.  This means that he did those pushups in the span of 28 days.  So, divide 1,456 by 28 to get 52 pushups.

Answer:

15-(-26)

Step-by-step explanation:

positive is lower than negative so the remaining number will be negative.

Answer:

x = 4, y = 0

Step-by-step explanation:

Two find x and y, we can simply solve one of the two equations for one of the variables, and substitute it into the other.  That will provide one of the two values, which can then be plugged into either equation for the other value.  Let's do it:

[tex]2x - y = 8\\y = 2x - 8\\\\x + 3y = 4\\x + 3(2x - 8) = 4\\x + 6x - 24 = 4\\7x = 28\\x = 4\\\\y = 2x - 8\\y = 2(4) - 8\\y = 0[/tex]

So x is equal to four, and y is equal to zero.
