Complete the statement: In a glide reflection, the direction of the ______ must be parallel to the line of reflection.

1 answer:

8 0

The correct option is "translation"
In geometry, a glide reflection is a type of isometry of the Euclidean plane: the combination of a reflection in a line and a translation along that line. Reversing the order of combining gives the same result. Depending on context, we may consider a reflection a special case, where the translation vector is the zero vector. The combination of a reflection in a line and a translation in a perpendicular direction is a reflection in a parallel line. However, a glide reflection cannot be reduced like that. Thus the effect of a reflection combined with any translation is a glide reflection, with as special case just a reflection.

Using the Division algorithm to find q and r such that 3662 = q·16+r , where 0 ≤ r < 16 . What if we take c = −3662 instead o

bagirrra123 [75]

Answer:

a) If c=3662 then q=228 and r=14.

b) If c=-3662, then q=-229 and r=2

Step-by-step explanation:

a) Observe that 229*16=3664, since r must be in the interval [0,16), then 229 doesn't work, but 228*16=3648 and 3662-3648=14.

Then 3662=228*16+14.

b) Observe that -228*16=-3648 and -3648-14=-3662, but r= must be positive. Then -228 doesn't work.

But observe that -229*16=-3664 and -3664+2=-3662. So -3662=-229*16+2

Answer:

graph is shown below
absolute max and min do not exist
local max: 0 at x=0
local min: -500/27 ≈ -18.519 at x=10/3

Step-by-step explanation:

The function is odd degree so has no absolute maximum or minimum. It factors as ...

g(x) = x^2(x -5)

so has zeros at x=0 (multiplicity 2, meaning this is a local maximum*) and x=5.

Differentiating, we find the derivative of g(x) is zero at x = 0 and x = 10/3.

g'(x) = 3x^2 -10x = x(3x -10) ⇒ x=0 and x=10/3 are critical points

The value of g(10/3) is a local minimum. That value is ...

g(10/3) = (10/3)^2((10-15)/3) = -500/27 ≈ -18.519

The local maximum is (0, 0); the local minimum is (10/3, -500/27). The graph is shown below.

_____

* When a root has even multiplicity, the graph does not cross the x-axis. That means the root corresponds to a local extremum. Since this is the left-most root of an odd-degree function with a positive leading coefficient, it is a local maximum. (The function is increasing left of the left-most turning point.)
