Answer:
C. 72 million
Step-by-step explanation:
Put the appropriate value of x into the correct formula and do the arithmetic.
... For the year 2002, x = 2002 -1980 = 22.
Then the population estimate is ...
... h(22) = 51.42 +15.473·log(22)
... = 51.42 +15.473·1.3424
... = 51.42 +20.77
... = 72.19 ≈ 72 . . . . million . . . . . matches choice C.
(1) x = (6.6 +5)/2 = 5.8
(2) m = (4/3)*(13 -4) = 12
(3) p = (2/5)*(13 +3) = 6.4
(4) m = (11.5 -4.5)/3.5 = 2
(5) x = (21.5 -3.5)/9 = 2
6²÷2(3) +4
36/2(3)+4
=(18)(3)+4
=54+4
=58

Answer:
X² - 14x + 48= 0
Step-by-step explanation:
To find the quadratic equation well have to look for the root of the equation.
So the roots are at x= 6 and x= 8
The quadratic curve didn't pass the origin .
It intercepted the x axis at 6 and 8 and that's the roots.
So our equation is
(X-6)(x-8)= x²-8x -6x +48
X² - 14x + 48= 0
