Answer:

  D.  empty set

Step-by-step explanation:

Each of the operations X-Y and Y-X removes elements that are common to X and Y. The resulting two sets have no elements in common, so their intersection is the empty set.

_____

  X -Y = {2, 5, 6}

  Y -X = {3, 7, 8}

  {2, 5, 6} ∩ {3, 7, 8} = { }

If a cube of metal measures 3 cm on each side and has a mass of 216 g what is the density of the metal
ohaa [14]
The formula of density is mass / volume.
So, the volume is equal to the area of the cube by the total height, so the area of the cube is 3x3= 9, and this result multiplied by the height, 9x3 = 27.
Following the formula of density, we have 216 g / 27 cm^3, the result is 8 g/cm^3.
Hope you undestand my procedure XD

In what career would you most likely apply concepts from geometry?
Nitella [24]

Answer:

- Architect

- Cartographer and Photogrammetrist

- Drafter

- Mechanical Engineer

- Surveyor

- Urban and Regional Planner

Step-by-step explanation:

Architects utilize geometric principles while designing layouts for their ongoing projects, which can include buildings, electrical systems, and plumbing architecture.

Cartographers utilize geographic data to create or update maps for use in education, as well as environmental presentations.

Using the same geometric knowledge and applications as architects and engineers, drafters create design plans with the use of computer-aided design (CAD) software.

Mechanical engineers, some of the most diversified engineers, use a multitude of geometric concepts to design mechanical devices, or update existing structures.

Surveyors use geometry to take exact measurements of boundaries for different types of property.

Urban and regional planners rely on the same geometry practices used by surveyors when examining the positives and negatives of introducing new and updated plans for a community.
