Consider the relation R on the set S = {1, 2, 3, 4} defined by
Nataly [62]

Answer:

Step-by-step explanation:

a) A relation R is symmetric when it includes the inverse relation, for example if it includes (8,9) then it should also include (9,8), if not, then the relation is not symmetric, you can see that in this case the relation includes (3,4) but not (4,3), therefore it is not symmetric

b) A relation is antisymmetric when it never includes the inverse relation, for example if it includes (8,9) then it can not include (9,8), if it does then it is not antisymmetric. In this case you can see that it first starts with (1,2) but then it also includes (2,1) so then it is not antisymmetric

c) A relation is reflexive if for each number of the domain set it includes the pair that is two times that same number, for example if 8 is in the domain then the relation should include (8,8). if not then it is not reflexive. In this case you can see that the domain S includes 1 but (1,1) is never on the relation or for example (2,2) is also never in the relation.

Sal is tiling his entryway. The floorplan is drawn on a unit grid. Each unit length represents 1 foot tile cost $1.25 per square
Tresset [83]

Answer: Sal will pay $77.78 to tile his entryway

Step-by-step explanation:

The image of the question is attached below.  

Given each unit length = 1 foot  

Tile cost per square feet = $1.  65

To find the area, split the floor shape into two shape.  

One is trapezoid and the other is parallelogram.  

Let's count the grid given.  

The parallels sides of trapezoid are 7 ft and 4 ft, height is 7 ft.  

The base and height of the parallelogram are 4 ft and 4 ft respectively.  

Area of the trapezoid  

                                 

                                 

Area of the trapezoid = 27.5 sq.ft  

Area of the parallelogram = base × height  

                                       = 4 ft × 4 ft  

Area of the parallelogram = 16 sq. ft  

Total area = 27.5 sq. ft + 16 sq. ft  

              = 43.5 sq. ft  

Cost of area per sq. ft = $1.65  

Cost of area 43.5 sq. ft = 43. 5 × 1.65  

                                   = $71.775

                                   = $71.78  

Hence Sal will pay $71.78 to tile his entryway.

I dunno how to solve this
Ksenya-84 [330]

Answer:

9

Step-by-step explanation:

First off you need to find the interval that four falls in.  

Four is not less than three so you can rule out the first one, four is not greater than 10 so you can rule out the last one.  But four is greater than three and less than ten, so it falls in the second interval.

So, now you can substitute four in for x for the second equation

4^2-7

16-7

=9
