How many rectangular faces does a hexagonal pyramid have

Answers

The total number of rectangular faces in a hexagonal pyramid is 5: 1 rectangular face for the base and 4 rectangular faces on the sides of the pyramid.

A hexagonal pyramid, also known as a hexagonal pyramid, is a type of pyramid with a hexagonal base. The base has six sides (hexagon), and it is connected to a single apex (vertex) at the top.

The number of rectangular faces in a hexagonal pyramid is 5.

The base of the pyramid is a hexagon, which consists of 6 triangular faces (each side of the hexagon forms a triangle with the apex).

The lateral faces of the pyramid are triangles that connect each of the six vertices of the hexagonal base to the apex.

Since the lateral faces are triangles, there are no rectangular faces among them.

Find the range of the function for given domain
f(x)=2x-7; (-2,-1,0,1,2)

Answers

Answer:

  {-11, -9, -7, -5, -3}

Step-by-step explanation:

Put each domain value into the function to find the corresponding range value. The range is the list of all of those values.

__

  range = f(domain)

  = 2{-2, -1, 0, 1, 2} -7 = {-4, -2, 0, 2, 4} -7

  = {-11, -9, -7, -5, -3} . . . . . the range for the given domain

_____

If you have a lot of function values to find, a spreadsheet or calculator can be helpful.

Final answer:

By substituting values from the domain (-2, -1, 0, 1, 2) in the function f(x) = 2x - 7, we get the range as {-11, -9, -7, -5, -3}.

Explanation:

In the given function f(x) = 2x - 7, to find the range, we substitute the values from the given domain (-2,-1,0,1,2).

  1. For x=-2, f(-2)= 2*(-2) -7 = -4 -7 = -11.
  2. For x=-1, f(-1)= 2*(-1) -7 = -2 -7 = -9.
  3. For x=0, f(0)= 2*(0) -7 = 0 -7 = -7.
  4. For x=1, f(1)= 2*(1) -7 = 2 -7 = -5.
  5. For x=2, f(2)= 2*(2) -7 = 4 -7 = -3.

Hence, the range of the function for the given domain (-2,-1,0,1,2) is {-11, -9, -7, -5, -3}.
