Rotation symmetry is also called mirror symmetry.

false, reflection

Rotational symmetry, also known as radial symmetry in geometry, is the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct orientations in which it looks exactly the same for each rotation.

Certain geometric objects are partially symmetrical when rotated at certain angles such as squares rotated at 90°, however, the only geometric objects that are fully rotationally symmetric at any angle are spheres, circles, and other spheroids

Rotational symmetry is symmetry with respect to some or all rotations in m-dimensional Euclidean space. Rotations are direct isometries, i.e., isometries preserving orientation.

Symmetry with respect to all rotations about all points implies translational symmetry with respect to all translations.

Answer:mhmm cool b

Step-by-step explanation:

The equation in slope-intercept form is y = 4x + 1

Given,

Points (x, y) = (-1, 5)

Parallel to y = 4x - 5

Now,

Recall that a parallel line to the one given has to have the same slope. The slope of the line given is "4" (the coefficient that accompanies "x").

Therefore the equation of a parallel line has to be of the form:

y = 4x - b

5 = 4(-1) - b

5 = -4 - b

b = -4 - (-5)

b = -4 + 5

b = 1

So the equation now becomes:

y = 4x + 1

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of ∠3 is 31°.

When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."

Given that ∠2 and ∠3 are supplementary angles. Therefore, the sum of the two angles will be 180°. Thus, we can write the sum of the two angles as,

∠2 + ∠3 = 180°

Also, it is mentioned in the question that the measure of ∠2 is 149°. Therefore, substitute the value of ∠2 in the above equation.

149° + ∠3 = 180°

∠3 = 180° - 149°

∠3 = 31°

Hence, the measure of ∠3 is 31°.

If the cost of renting a pool at an aquatic center is either 30 per hour or 20 per hour with a 40 non-refundable deposit, then the cost of renting the pool is the same for both plans for 4 hours.

The number of hours for which the cost of renting the pool will be the same for both plans can be calculated by using an algebraic expression.

An algebraic expression is a type of equation that consists of both numbers and letters.

An algebraic expression for this problem can be given as,

30(x) = 20(x) + 40

Where x is equal to the number of hours.

The value of x can be calculated by rearranging the equation,

30(x) - 20(x) = 40

10(x) = 40

x = 40 ÷ 10

x = 4

Thus, the number of hours for which the cost of renting the pool same for both plans is 4 hours.

The greatest number of comparisons each operation in the method add needs, given a binary search tree with n nodes and height h, is O. (h).

Computer scientists utilize the search method known as binary search to locate a target value within a sorted array. Binary chop, logarithmic search, and half-interval search are other names for it. The binary search compares the target value to the array's center member. If not, the half where the target cannot lie is eliminated, and the search is then carried out on the remaining half while once again comparing the center element's value to the target value. Up till the goal value is found, this process is repeated. if, at the end of the search, the remaining half is empty.

The largest area that can be enclosed will be 2812.5 square meters.

The perimeter of a rectangle is given as:

2L + 2W  ∴ L = length and W = width

As the farmer does not want to fence the side along the river, then the formula will be:

P = L + 2w

Now

150 = L + 2w

L = 150 - 2w

Here the area is LW

Area = (150 - 2W)(W)

After solving we get

150 - 2W = 0 or W = 0

150 - 2W = 0

2W = 150

W = 75

Now, there are two solutions whether 0 or 75

Let's find their average 0+75 / 2 = 37.5

Now L = 150 - 2(37.5)

L = 150 - 75

L = 75

As the dimensions are L = 75 and W = 37.5

Area = L x W = 75 x 37.5 = 2812.5 square meters

Step-by-step explanation:

You seem to want 10^exponent, where exponent is an even single digit, not zero.

We choose exponent = 2, so your expression is ...

10^2

__

There are several versions of expanded form. One uses exponents. In that form, the expression above is the expanded form.

Another uses multipliers of 1, 10, 100, 1000, and so on. In that form, the expression expands as ...

10^2 = 1×100

Another expanded form uses individual digits of the expanded form with others set to zero

10^2 = 100

The standard form is ...

10^2 = 100.

_____

We suppose your exponential expression might have another multiplier, such as 2.98:

exponential expression: 2.98×10^2

standard form: 298

expanded form 1: 2×10^2 + 9×10^1 +8×10^0

expanded form 2: 2×100 +9×10 +8×1

expanded form 3: 200 + 90 + 8

The cost for x rides is modeled by the linear function:

c(x) = $15 + $2.50*x

A table and a graph for that function are provided below.

Here we know that the entrance fee to the fair is $15, and the cost of each ride on the fair is $2.50

So, if you go to the fair and enter in x rides, the total cost for that will be modeled by the linear function:

c(x) = $15 + $2.50*x

Now let's find a table, to do that we just need to evaluate the function in some values of x, I will use x = 0, x = 1 and x = 2, we will get:

C(0) = $15 + $2.50*0 = $15

C(1) = $15 + $2.50*1 = $17.50

c(2) = $15 + $2.50*2 = $20.00

Then we can write the table:

Number of rides |||    Cost

      0                          $15

       1                          $17.50

       2                         $20.00
