all positive real

all real number greater
than or equal to 5
all real numbers
all real numbers
except 8

Step-by-step explanation:

1). f(z) =

   The given function 'f' is defined for (z - 5) ≥ 0

    z ≥ 5

   Therefore, domain of the function will be [5, ∞)

   Or "All real numbers greater than or equal to 5"

2).

    Domain: "All real numbers except 8."

    Since the given function is not defined for z = 8

3). f(z) =

    The given function is defined for every real numbers greater and equal to zero.

    Domain: "All positive real numbers and 0"

4). f(x) = 8x

    This function is defined for all real numbers.

    "Domain: All real numbers"

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
