Umbilical
point.
An
umbilic point, likewise called just an umbilic, is a point on a surface at
which the arch is the same toward any path.
In
the differential geometry of surfaces in three measurements, umbilics or
umbilical focuses are focuses on a surface that are locally round. At such
focuses the ordinary ebbs and flows every which way are equivalent,
consequently, both primary ebbs and flows are equivalent, and each digression
vector is a chief heading. The name "umbilic" originates from the
Latin umbilicus - navel.
<span>Umbilic
focuses for the most part happen as confined focuses in the circular area of
the surface; that is, the place the Gaussian ebb and flow is sure. For surfaces
with family 0, e.g. an ellipsoid, there must be no less than four umbilics, an
outcome of the Poincaré–Hopf hypothesis. An ellipsoid of unrest has just two
umbilics.</span>
Answer:
66) P = 38m
67) P = 32.7m
Step-by-step explanation:
Perimeter of triangle
P = a + b + c
P = 8 + 16 + 14
P = 38m
Perimeter of trapezoid
P = a + b + c + d
P = 6.4 + 13.6 + 6 + 6.7
P = 32.7
Since we know that t = 3.4 you put 3.4 where the t is.
2 (36 - 4 × 3.4) So what you do first is multiply 4 and 3.4 which gives you 13.6
2 (36 - 13.6) then you subtract 36 and 13.6 which gives you 22.4
2 (22.4) then you multiply 2 and 22.4 which is 44.8.
So your answer is 44.8

Answer:
x=7/6
Step-by-step explanation:
subtract the 4x from both sides of the equation
(2x+6)-4x=4x-3-4x
find common denominator
(2x+6)/5+(5(-4)x)/5=4x-3-4x
then combine fractions
(2x+6+5(-4)x)/5=4x-3-4x
then multiply the 5&4
(2x+6-20x)/5= 4x3-4x
combine terms
(-18x+6)/5= -3
then multiply everything by 5
-18x+6= -15
subtract the 6 from both sides
-18x= -21
divide -21 by -18
(-21)/(-18)=x
find greatest common multiple (3) and solve
x = 7/6
