Answer:
C
Step-by-step explanation:
X vertex = (0, - 3)
ax² + bx + c = y
0.x² + b.0 + c = - 3
c = - 3
Then:
The graphic of g(x) is the a one is negative, because the curve is below.
Then:
g(x) = - x² - 3

Answer:
C =37.68 mm
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
C = 2(3.14)*6
C =37.68 mm
We know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
V - E + F = 2
clear F
F=2-V+E
in this problem
V=8
E=14
F=?
so
F=2-8+14
F=8
the answer is8 faces
