Omg ur keeping me awake with these notifications!! LOL :-D. JK
Arc RQ is a [minor arc] only because it is less than half the circle, which is 180 [PQ]
** remember that 180° always = half a circle
Answer:
Maybe 3 1/2 but they don't give enough information
For this case we have that an inverse variation in a function is given by:

For this case, we must find the value of the constant k.
To do this, we substitute the values of x = -4, y = 8.
We have then:

Clearing k we have:

Substituting the value of k we have that the inverse variation is:

Note: see attached image.
Answer:
See attached image.
8√3*12 + (-18)
First multiply 3 * 12:
8√36 + (-18)
Rewrite 36 as 6^2
8√6^2 + (-18)
Calculate the square root:
√6^2 = 6
8*6 + (-18) =
48 - 18= 30
