What is the domain and range of the relation shown in the table?
TEA [102]

Answer:

<u>domain: {10,15,19,32}</u>

<u>range:{5,9,-1}</u>

Step-by-step explanation:

  • As we know domain is the values of input and range is the values of output.
  • Here , x is the input and y is the output.
  • \left[\begin{array}{cc}x&y\\10&5\\15&9\\19&-1\\32&5\end{array}\right]
  • Thus the input values according to the given problem is : 10 ,15 , 19, and thus ,

⇒<em>The domain would accordingly be these four numbers : 10 , 15 , 19 , 32.</em>

  • <u>Note that we donot have any information regarding the other values of x.</u>
  • The range is : { 5,9,-1 } only as the 5 is repeated in two cases .
  • Range is unique and there must be not repetition. Thus the apt answer would be :

<em>domain: {10,15,19,32}</em>

<em>range:{5,9,-1}</em>

The expression sin 50 cos 40 + cos 50 sin 40 is equivalent to
enyata [817]
Sin (a+b) = sin a. cos b + cos a. sin b

a= 50° and b=40°, then

sin(50+40) = sin 50° . cos 40° + cos 50° . sin 40°

sin(50+40) = sin 90° = 1 and

sin 50° . cos 40° + cos 50° . sin 40° = 1
