Mathematics

natta225 [31]3 years ago
8 0

Answer:

14

Step-by-step explanation:

Geometric mean = nth root (product of individual values of set of data)

from the question, n=2,

product of individual values of set of data= 2/5*490 = 196

Therefore Sqrt (196) =14

NB: As n is 2, we use sqrt, if n is 3, we use cube root and so on

Which of the following rational functions is graphed below?
Cerrena [4.2K]

Answer:

option B

Step-by-step explanation:

We can see in the graph that the function has two values of x where the value of y goes to infinity: x = -6 and x = 6.

These points where the value of the function goes to infinity usually are roots of the polynomial in the denominator of a fraction (when the values of x tend to these values, the denominator of the fraction tends to 0, so we have a discontinuity in the function).

So the option that represents a function that have these points in x = -6 and x = 6 is the function in option B.

The other options show functions that have only one point that goes to infinity.
