It is B. Since each angle is 60 degrees, if you rotate B counterclockwise 6 times, it means that you rotated B 360 degrees. Therefore, the image of B would be B.

Answer:

B will be at same place after all six rotations.

Step-by-step explanation:

If rotation maps to 60^{\circ}

Then [tex]R^6[tex] means six rotations .

The given B after one rotation will shift in place of A

After second rotation will shift in place of F

After third rotation will shift in place of E

After fourth rotation will shift in place of D

After fifth rotation will shift in place of C

After sixth rotation will shift in place of B itself.

Therefore, B will come back to same place after all the required rotations.

Answer:  [c, ∞)

<u>Step-by-step explanation:</u>

Range is all of the y-coordinates.

The parabola is upright (∪) because the coefficient of x² is positive.

So the minimum value is at "c" and the parabola tends toward infinity.

Range: y ≥ c    <em>in Interval Notation</em>: [c, ∞)

4. 1/3(3y - 6) = 8 i need the answer to this please​
tiny-mole [99]

1/3 (3y - 6) = 8

distribute: y - 2 = 8

add 2 to both sides: y = 10

A convex polyhedron has (a + 3) faces, (2a) vertices, and (4a – 1) edges. What is the value of a? a =
rusak2 [61]
Number of faces: F=a+3
Number of vertices: V=2a
Number of edges: E=4a-1

V+F-E=2
Replacing V=2a; F=a+3; and E=4a-1 in the formula above:
(2a)+(a+3)-(4a-1)=2
Eliminating parentheses:
2a+a+3-4a+1=2
Adding similar terms:
(2+1-4)a+(3+1)=2
(-1)a+4=2
Solving for a. Subtracting 4 both sides of the equation:
(-1)a+4-4=2-4
(-1)a=-2
Dividing both sides by (-1)
(-1)a/(-1)=-2/(-1)
a=2

Answer: The value of a is: a=2

Identify the x- and y- intercepts of this equation. 5 − 4 = 20
Alinara [238K]

T he x and y intercepts of the equation: 5x-4y=20 are : y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.

Step-by-step explanation:

we need to identify the x and y intercepts of the equation: 5x-4y=20

Finding x-intercept

For finding x-intercept put y=0

We are given the equation:

5x-4y=20

Solving:

5x-4y=20\\5x-4(0)=20\\5x=20\\x=\frac{20}{5}\\x=4

So, x-intercept is (4,0)

Finding y-intercept

For finding y-intercept put x=0

We are given the equation:

5x-4y=20

Solving:

5x-4y=20\\5(0)-4y=20\\-4y=20\\y=\frac{20}{-4}\\y=-5

So, y-intercept is (0,-5)

the x and y intercepts of the equation: 5x-4y=20 are :y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.
