which of the following best describes rotational symmetry

Answers

Answer 1

Answer: B

Step-by-step explanation:

A best describes the quality of symmetry, not specifically rotational symmetry.

C applies to that of A.

D applies to flipping an image across an axis.

B specifically outlines the symmetry of an object when rotated, thus B would be the most precise answer.

A polygon is graphed on a coordinate plane, with a vertex located at
a point represented by (x,y).
The polygon is dilated with a scale factor, a , with the origin as the
center of dilation. The dilated image of the polygon is larger than
the polygon.
Which statement is true?

Answers

Answer:

a is greater than 1

Step-by-step explanation:

Let the two polygons be represented as A and B.

Where A is the original polygon and B is the image of A

Such that

Polygon A has vertex (x,y) and scale factor = a

From the question, we understand that polygon B is bigger than A

When the dilated image (polygon B) is bigger than the original image (polygon A), then the scale factor is greater than 1.

Take for instance.

One of the coordinate point of polygon A is (2,4)

The corresponding coordinate point of polygon B will be greater than (2,4) because a is greater than 1.

Take a as 2:

The corresponding point on Polygon B would be 2 * (2,4) = (4,8)

Yuri drew triangle ABC then reflected it over line m to create triangle WXY.
Yuri concludes that the triangles are congruent. Which is a correct validation for this conclusion?
When the triangle was reflected, the height of the resulting triangle is parallel to the height of the original triangle.
When the triangle was reflected, the base of the resulting triangle lies on the same line as the base of the original triangle.
When the triangle was reflected, the corresponding sides and angle measures of the resulting triangle are the same as the original triangle.
When the triangle was reflected, the corresponding sides of the resulting triangle have slopes that are opposite to the slopes of the original triangle.

Answers

Answer:

a) x^(2) + 2x + 1

b) x^(2) + 1

c) 16

d) 1

Step-by-step explanation:

f(x) = x^(2)

g(x) = x + 1

f(g(x))

input g(x) into f(x)

f(x+1) = (x+1)^(2)

= x^(2) + 2x + 1

g(f(x))

input f(x) into g(x)

g(x^(2))

x^(2) + 1

f(g(3))

Use the equation found in part a, substitute in 3 for x

(3)^(2) + 2(3) + 1

= 9 + 6 + 1

= 16

Use the equation found in part a, substitute in 0 for x

(0)^(2) + 2(0) + 1

= 0 + 0 + 1

= 1

The minute hand of a clock is 4 inches long. How far does the tip of the minute hand move in 35 minutes? If necessary, round the answer to two decimal places.

Answers

Answer:

14.66 inches

Step-by-step explanation:

Calculation for How far does the tip of the minute hand move in 35 minutes

The tip of a minute hand will always travels at 360 degrees in an hour ( 60 minutes)

Hence, the tip of the minute hand

distance will be calculated using this formula

Circumference of a circle=2*π*Radius* Clock Tip hand movement/Number of minutes per hour

Let plug in the formula

Circumference of a circle==2*π*4 inches*35 minutes/60 minutes

Circumference of a circle= =2*π*4 inches*0.58333

Circumference of a circle==14.659 inches

Circumference of a circle==14.66 inches (Approximately)

Therefore How far does the tip of the minute hand move in 35 minutes will be 14.58 inches
