Which relation is displayed in this table?
elena-s [515]

Answer:

D

Step-by-step explanation:

As we can observe from the answers the representation is about the pair of points. We can sort it out by excluding the wrong options.

Options B and C is incorrect because the place of x and y coordinate is given mistakenly for the point (1,2)

The option A is incorrect due to the same problem for the point (8,7)

The correct option is D.

Which expression can be used to find the surface area of the following square pyramid
andreyandreev [35.5K]

Answer:

36+15+15+15+15

Step-by-step explanation:

For the surface area we need to add up all the areas in the pyramid:

  • area of the base
  • area of the triangle sides (there are 4 triangles)

Area of the base:

the base is a square, and the area of a square is given by:

a_{base}=l^2

where l is the length of the side: l=6, thus:

a_{base}=(6)^2\\a_{base}=36

Area of the triangles:

one triangle has the area given by the formula:

a_{triangle}=\frac{b*h}{2}

where b is the base of the triangle: b=6

and h is the height of the triangle: h=5, thus we have the following:

a_{triangle}=\frac{6*5}{2} \\\\a_{triangle}=\frac{30}{2} \\\\a_{triangle}=15

the expression that represents the surface area of the pyramid is:

a_{base}+area_{triangle}+area_{triangle}+area_{triangle}+area_{triangle}

substituting our values:

36+15+15+15+15

which is option B
