Answer:

Step-by-step explanation:

surface area of cube = 6×8² = 384 cm²

lateral area of pyramid = surface area of pyramid - base area

= 384 - 8²

= 320 cm²

area of triangular face = 320/4 = 80 = ½(base)(slant height) = ½(8)(slant height)

slant height = 20 cm

For what value of \\(x\\) is the function \\(\\frac{1}{x-2}\\) not defined?
natima [27]

for the value of x=2 we have the function  f(x) = 1/(x-2) or f(x)=\frac{1}{x-2}  as undefined or not defined .

<u>Step-by-step explanation:</u>

<u>Function undefined: </u> A function is undefined when it gives results which are not defined for example , infinity  .

Here we have , Function f(x) = 1/(x-2) or f(x)=\frac{1}{x-2} . We need to find a value of for which this is not defined . Let's find out:

We can clearly see that it's a fractional function with numerator as 1 and denominator as x-2 . For a fractional function to be undefined it's denominator must be zero i.e.  x-2 = 0 or x-2=0

⇒ x-2=0

⇒ x-2+2=0+2

⇒ x=2

Therefore, for the value of x=2 we have the function  f(x) = 1/(x-2) or f(x)=\frac{1}{x-2}  as undefined or not defined .
