First differences are ... 0-7 = -7, -1-0 = -1, 4-(-1) = 5, 15-4 = 11, 32-15 = 17.
Second differences are -1-(-7) = 6, 5-(-1) = 6, 11-5 = 6, 17-11 = 6.
The second differences are constant at 6, so the table values would be best fit by a function that is ...
_____
The degree of the polynomial function corresponds to the level of differences that are constant (when the x-values are evenly spaced).
The quadratic function that matches these values is
... y = 3x² +2x -1
... y = (3x-1)(x+1) . . . . in factored form
Answer:
B (-3)
Step-by-step explanation:
9/81 or 1/9 = .1111111111R
It is that because that is the decimal and 9 goes into 9 once and 9 goes into 81 nine times
The Circumference of the circle is 18.84 ft.
Here,
Diameter = 2 × Radius
d = 2(3) ft
d = 6 ft
Now,
C = πd
C = 3.14 × 6
C = 18.84 ft
Thus, The Circumference of the circle is 18.84 ft.
