The difference between the set of non-negative real numbers and the set of positive real numbers is:

Inessa05 [86]

Answer:

C; A singleton set

Step-by-step explanation:

Mathematically, when a number is non-negative; it is either positive or zero

Now, this is because 0 identifies as neither a positive or a negative number

hence, when we find the difference between the two sets, the only number that stands out unmatched is the value 0

What this mean is that we are having a set with a single number result

So we have our answer as {0}

Which is a singleton set

A rope is swinging in such a way that the length of the arc traced by a knot at its bottom end is decreasing geometrically. If t

nikdorinn [45]

Answer:

The length of the arc on the sixth swing was 12.18 ft.

Step-by-step explanation:

A rope is swinging in such a way that the length of the arc traced by a knot at its bottom end is decreasing geometrically.

The third arc is 22 ft. long and the seventh arc is 10 ft.

Hence, the 3rd term is 22 and 7th term is 10.

The length of the arc on the sixth swing is asked, so we have to calculate the 6th term.

We know the nth term in GP is,

$T_n=ar^{n-1}$

So,

$T_3=ar^{3-1}=ar^2$ ----------------1

$T_7=ar^{7-1}=ar^6$ ----------------2

Dividing equation 2 by 1,

$\Rightarrow \dfrac{T_7}{T_3}=\dfrac{ar^6}{ar^2}$

$\Rightarrow \dfrac{10}{22}=\dfrac{ar^6}{ar^2}$

$\Rightarrow \dfrac{10}{22}=\dfrac{r^6}{r^2}$

$\Rightarrow \dfrac{r^6}{r^2}=\dfrac{10}{22}$

$\Rightarrow r^4=\dfrac{10}{22}$

$\Rightarrow r=\sqrt[4]{\dfrac{10}{22}}$

$\Rightarrow r=0.8211$

Then the 6th term will be,

$T_6=ar^{6-1}=ar^5$ ----------------3

Dividing equation 2 by 3,

$\Rightarrow \dfrac{T_7}{T_6}=\dfrac{ar^6}{ar^5}$

$\Rightarrow \dfrac{10}{T_6}=\dfrac{a(0.8211)^6}{a(0.8211)^5}$

$\Rightarrow \dfrac{10}{T_6}=0.8211$

$\Rightarrow T_6=\dfrac{10}{0.8211}=12.18\ ft$

Therefore, the length of the arc on the sixth swing was 12.18 ft.
