A scale distance of 3 centimeters on a map represents an actual distance of 51 feet.
Rom4ik [11]
In this case, the best way to work this out is to find what 1cm is equal to. In this case, you have to divide 51/3, giving you 17. You know that 17 feet. You can now divide 187/17, giving you 11. Therefore, 11cm is equal to 187 feet. Hope this helps

〽Hola User_______________

⭐Here is Your Answer..!!!

______________________

↪Cartesian Coordinates of the system....!!

↪X = rcos⊙ and Y = rsin⊙

↪since here Radius (r) = 10 units and Theta (⊙) = 225°

↪there fore substituting we get as ..

↪X = 10 ( cos 225° ) = 10 * -1/ root 2 = -7.071

↪Y = 10 ( sin 225° ) = 10 * -1/root2 = = -7.071

↪the cordinates are as follows

↪(x,y) = (-7.071, -7.071 )

Please include answer and explanation :))

Answer:

<em>Domain={2,5,8}</em>

<em>Range={1,3,6}</em>

<em>Function: YES</em>

Step-by-step explanation:

<u>The Domain of a Function </u>

Is the set of values the input variable x takes.

<u>Range of a Function </u>

It's the set of values the output function takes when x moves into the function's domain.

A function is a relation between an input and an output set of values with the condition that every element in the domain relates only with one element in the range.

Following the definitions above, the domain of the relationship is the set of input values:

Domain={2,5,8}

The range is the set of output values:

Range={1,3,6}

Since each element in the input set is related only to one element in the range, the given relationship is a function.

Answers:

Domain={2,5,8}

Range={1,3,6}

Function: YES
