What is the domain and range of each relation?

Mathematics

LUCKY_DIMON [66]4 years ago

Answer:

\text{Domain of}R_1=\{-2,0,2,4\}  and \text{Range of}R_1=\{-3,-1,0\}

\text{Domain of}R_2=\{-3,-1,0,3\}  and \text{Range of}R_2=\{-1,0,1,2,3\}

Step-by-step explanation:

Domain is the set of input values or x-values.

Range is the set of output values or y-values.

According to the relation mapping diagram, the relation is

R_1=\{(-2,-3),(-2,-1),(0,0),(2,0),(4,-3)\}

So,

\text{Domain of}R_1=\{-2,0,2,4\}

\text{Range of}R_1=\{-3,-1,0\}

In the graph 5 points are plotted. So, the relation is  

R_2=\{(-3,1),(-1,-1),(0,0),(3,2),(3,3)\}

So,

\text{Domain of}R_2=\{-3,-1,0,3\}

\text{Range of}R_2=\{-1,0,1,2,3\}

Find the area of the polygon
larisa [96]

Answer:

687.5 \:  {ft}^{2}

Step-by-step explanation:

Area of polygon = Area of square + Area of triangle

=  {25}^{2}   + \frac{1}{2}  \times 25 \times (30 - 25) \\  \\  = 625 +\frac{1}{2}  \times 25 \times5 \\  \\  = 625 +  \frac{1}{2}  \times 125  \\  \\  = 625 + 62.5 \\  \\  = 687.5 \:  {ft}^{2}

Newton's Law of Gravitation:

Statement: According to this law, when two mass bodies are separated at finite distance then there must be an attractive force experience by them which is directly proportional to the product of their masses and inversely proportional to the square of their separation.

Consider two mass bodies m1 & m2 be kept at distance d. Then the force of attraction F is given as

                            Fam_{1}.m_{2}

                                 Fa1/d^2

Now, from above equations, we have

                          Fa\frac{m_{1}m_{2}}{d^2}

or,                           F=G\frac{m_{1}m_{2}}{d^2}

Here         G=6.67*10^{-11}Mm^2kg^{-2}   is the universal gravitational constant.

Answer:

  • x = 4

Step-by-step explanation:

x has the same value as RT since they are equal sides of the isosceles triangle.

RT is also the hypotenuse of ΔRST - 30°×60°×90° right triangle.

Acoording to the property of such triangles, the ratio of sides is:

  • a : b : c = 1 : √3 : 2

We have:

  • b = 2√3 and c = RT

Use the ratio to find the lenght of RT

  • 2√3 : RT = √3 : 2
  • RT = 2*2√3/√3
  • RT = 4

So the value of x is 4 units
