y = cos ^- 1 (x)
Step-by-step explanation:
The Function y = cos -1x = arccos x and its Graph: Since y = cos -1x is the inverse of the function y = cos x, the function y = cos -1x if and only if cos y = x. This leaves the range of the restricted function unchanged as [-1, 1].
Absolute value is simply the distance from zero on a number line. -44 is 44 away from zero, so the absolute value of -44 is
44
It's 8 if you're doing ones but if you're doing tenths it's 8.4 and i

Answer:
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
Step-by-step explanation:
Given that,
The number of phone calls between two cities (N )
- directly proportional as the value of populations
and 
of two cities. - Inversely varies as the magnitude of distance (d).
Given that,
N=18,000, d=310 miles, =15,500 and =180,000
Now,
N=? , d=435 miles, =100,500 and =160,000
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
