The domain is {-8}
The range is {5,6,7,8}
The relation is not a function as the domain value -8 maps to multiple values. All domain values in a relation needs to map to exactly one range value for it be a function.
Recall that, an absolute value expression is a piece-wise in effect, thus we'd check the single-sided limits,
Answer:
V≈7240.89
Step-by-step explanation:
Use the formula V=A^(3/2) / ![6\sqrt[n]{pi}](https://tex.z-dn.net/?f=6%5Csqrt%5Bn%5D%7Bpi%7D)
Answer:
24.76 mine
Step-by-step explanation:
The first thing is to calculate the area of the region, which we can calculate since we have the density and the population. The area would be the quotient between population and density:
260000/135 = 1925.93
The area would be 1925.93 square mine
We know that the area is given by:
A = pi * r ^ 2
we solve to r
r ^ 2 = A / pi
r ^ 2 = 1925.92 / 3.14
r ^ 2 = 613.3
r = 24.76
the radius is equal to 24.76 mine
