The answer is 85.5
The circle is pi•r squared
And then u find the triangle area which is pi•slant height•r
This problem can
be directly solved by ratio and proportion.
We know that there
are 646,449 people for every 68.3 square miles, so:
646,449 people : 68.3
square miles = X : 570,374 square miles
We know that the :
symbol signifies division therefore,
646,449 / 68.3 = X
/ 570,374
X = 5,398,502,224

Answer: D
Step-by-step explanation:
It increases dramatically, reaches its end point and decreases just as fast
(f+g)(x) = 2x - 1 + x^2 + 7 = x^2 + 2x + 6
(f-g)(x) = 2x - 1 - x^2 - 7 = -x^2 + 2x - 8
(f*g)(x) = (2x - 1)(x^2 - 7) = 2x^3 - 14x - x^2 + 7 = 2x^3 - x^2 - 14x + 7
(f/g)(x) = (2x - 1)/(x^2 - 7) - No simplification
f(g(-8)) = 2((-8)^2) - 7) - 1
= 2(64 - 7) -1
= 2(57) - 1 = 114 - 1 = 113
g(f(1)) = (2(1) - 1)^2 - 7
= (2 - 1)^2 - 7
= 1^2 - 7 = 1 - 7 = -6
