<span>In general, if the pyramid has 'x' sides, then it will have 'x' lateral faces. Total Number of Faces = Number of Base Faces + Number of Lateral Faces. Total Number of Faces = 2 + x. So the formula is F=x%2B2 where "x" is the number of sides that the pyramid has and "F" is the total number of faces.</span>

Answer: The expression for number of faces of a pyramid =1+n


Step-by-step explanation:

A Pyramid is a polyhedron or a three dimensional shape having a polygon base and all lateral faces are triangles .

Its base describe the number of other faces of it.

For example a triangular pyramid has a triangular base which gives rise to 3 lateral faces , and a rectangular pyramid has a rectangular base which give rise to 4 lateral faces and so on.....

So the total number of faces in a pyramid = base + lateral faces

If a pyramid has n sides therefore it give rise to n lateral faces such that

The total number of faces in a pyramid= 1+n .

-Dominant- [34]

Answer:

7595.96 × 0.02 × x = y

Step-by-step explanation:

1. We start with $7595.96.

2. The interest is 2% or 0.02

3. Using this formula - P(Principle) x R(Rate) x T(Time) we pluck in the numbers.

4. 7595.96(Principle) x 0.02(Rate) x x(Time) = y(amount of money in the account after x years).

F(x)=x^2-3x-2 is shifted 4 units left. The results is g(x). What is g(x)?
marusya05 [52]

Answer:

B. g(x)=(x+4)^2-3(x+4)-2

Step-by-step explanation:

The given function is

f(x)=x^2-3x-2

If f(x) is shifted to the left 4 units and the result is g(x).

Then;

g(x)=f(x+4)

We substitute (x+4) into f(x)=x^2-3x-2 to find the g(x).

g(x)=(x+4)^2-3(x+4)-2

The correct choice is B.

Determine if the data in the table represents a proportional relationship. If yes, give the constant rate.
Flauer [41]

Answer:

no, it is not a proportional relationship.

Step-by-step explanation:

if you divide 315 by 175 you get 1.8

if you multiply 315 by 1.8, you don’t get 420. therefore this is not a proportionally relationship.

hope this helps!
