The scale of figure A to Figure B is given by 9 : 5 and option C is the correct answer.

Shapes in various dimensions can be scaled using the Scale Factor. In geometry, we study many geometrical forms that exist in both two- and three-dimensions. The scale factor is a way to compare figures with similar appearances but differing scales or measurements. Consider two circles that resemble one another but may have different radii.

The scaling factor indicates how much a figure has increased or decreased from its initial value.

The scale of figure A to Figure B is given by:

Scale factor = Segment of figure A / segment of figure B

SF = 36 / 20

SF = 9 / 5

Hence, the scale of figure A to Figure B is given by 9 : 5 and option C is the correct answer.

7000 is the 3 period moving average forecast for week 6.

Using a moving average, a data set's general trend may be determined. The sales volume from the company's historical data is the data set used in operations management. For predicting recent trends, this method is quite helpful. Simply said, it is the average across a range of times.

The most basic method for predicting is a simple moving average (SMA). The data from the previous 'n' periods are added up, and the sum is divided by 'n' to create a simple moving average. So the projection for the following period is based on the moving average value.

3-period weighted moving forecast for week 6:

= (Demand for Period 3 + Demand for Period 4 + Demand for Period 5) / 3 = (8000 + 7000 + 6000) / 3

= 7000

The radius of the circle with the same vertex is 6 and the height of the triangle is 10.39 and the area of the triangle is 62.34.

Since the arc divides the triangle into two regions of equal area, it follows that half of the circle's area is equal to the area of the triangle. The area of a triangle with sides 12 and 12√3 and a 60-degree angle can be found using the formula for the area of a triangle, which is 0.5bh.

The height of the triangle can be found using trigonometry, as the sine of 60 degrees is 0.8660. Thus, the height of the triangle is 10.39 and the area of the triangle is 62.34.

Since half of the circle's area is equal to the area of the triangle, the radius of the circle can be found by taking the square root of the area of the triangle and dividing it by pi. Thus, the radius of the circle is 6.

(2t)^-6 = 1/(2t)^6 is expression of only positive exponents.

An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.

here, we have,

the given expression is, (2t)^-6.

Now,

To simplify this using only positive exponents we are going to use the rule for negative exponents: b^(-n) = 1/b^n .

Answer:

central angle

Step-by-step explanation:

an angle with a vertex on the center of a circle and slides that are radii of that circle is called a central angle

Central angle has a vertex on the center of the circle and sides that are radii of that circle .

What does central angle mean?

A right angle, which has sides that are the radii of the circle, and a vertex that is at the center of the circle Given that it intercepts an arc with a length equal to the circle's radius, a central angle has radian measure [Math Processing Error].

Where can I find the center angle?

The angle that the arc at the center of a circle occupies is known as the central angle. The arms of the angle are created by the radius vectors. The formula for calculating a central angle is: Central Angle = Arc length(AB) / Radius(OA) = (s 360°) / 2r, where s denotes the length of the arc and r denotes the radius of the circle.

B) 4 - 3r

Step-by-step explanation:

B.  4 - 3r is the mathematical expression.

Step-by-step explanation:

up/down shifts are easy. they just indicate a constant change to the calculated y-values (result values) of f(x).

a shift up is therefore just adding a constant to f(x).

a shift down is just subtracting a constant from f(x).

in our case that would be f(x) + 3 = x³ + 3.

left/right shifts are more difficult to understand.

a shift to the left means that the same y-/result values happen as for f(x) also for g(x), just a bit "earlier" (to the left) on the x-axis.

a shift to the right means via the same principle the y-values for f(x) happen unchanged but "later" (to the right on the x-axis) for g(x).

so, 5 units to the left means that g(x) has the same y-value as f(x+5). f(x+5) happens 5 units earlier (at x).

and so, the full g(x) is

g(x) = f(x+5) + 3 = (x+5)³ + 3 =

= (x² + 10x + 25)(x + 5) + 3 =

= x³ + 5x² + 10x² + 50x + 25x + 125 + 3 =

= x³ + 15x² + 75x + 128

When a plane is inclined at a 45-degree angle and intersects a cylinder's base along its diameter with radius "r," it results in the division of the cylinder into two identical right circular cones.

Imagine a cylinder with a radius "r."

The plane passes through the cylinder's base, creating a line that bisects the circular base into two equal halves.

This intersection between the inclined plane and the cylinder forms a cross-section that resembles an isosceles right triangle.

By symmetrically splitting the cylinder along its central axis, the inclined plane generates two congruent right circular cones, each with a 45-degree angle at its apex. The curved line formed by the intersection represents the boundary between the two cone halves.

The distance from a to the line passing through b and c is 7/5.

To find the distance from a point to a line, you can use the cross product and the dot product.

First, find the vector pointing from a to b and the vector pointing from b to c:

u = b - a = (3, -5, 0) - (0, 3, -5) = (3, -8, 5)

v = c - b = (3, 0, -5) - (3, -5, 0) = (0, 5, -5)

Next, find the cross product of these two vectors, which gives a vector orthogonal to the plane defined by the line:

n = u x v = (-40, 0, 40)

Finally, find the dot product of n and a - b, which gives the magnitude of the projection of a - b onto n:

d = |n . (a - b)| / |n| = |(-40, 0, 40) . (-3, -8, -5)| / |(-40, 0, 40)| = 57 / √(40^2 + 40^2) = 57 / √1600 = 57 / 40 = 7/5

Therefore, the distance from a to the line passing through b and c is 7/5.

What is vector ?

Vector is a term that refers colloquially to some quantities that cannot be expressed by a single number, or to elements of some vector spaces.

A linear combination of vectors u and v is a vector of the form c1u + c2v, where c1 and c2 are scalars. There are infinitely many possible linear combinations of u and v, here are three examples:

c1u + c2v = (1) (3, -2) + (2) (-1, -5) = (3 + -2, -2 - 10) = (1, -12)

c1u + c2v = (0.5) (3, -2) + (-1) (-1, -5) = (1.5 + 1, -2 - 5) = (2.5, -7)

c1u + c2v = (2) (3, -2) + (-0.5) (-1, -5) = (6 + 0.5, -2 - 2.5) = (6.5, -4.5)

PQ=17.088

Step-by-step explanation:

If M is the midpoint of PQ, then PM is half the length of PQ. So we cna find our answer by first finding PM.

Imagine a right angle triangle with PM as its hypotenuse. Since P(x,y)=(5,-15), and M(x,y)=(13,-18), we know that the length of the vertical side of this triangle is the difference between P and M's y (vertical) coordinates, and the length of the horizontal side of this triangle is the difference between P and M's x (horizontal) coordinates. This means the vertical side is equal to -15-(-18)=3 and the horizontal side is equal to 13-5=8. Since we know the lengths of the other two sides and PM is the hypotenuse, we can use pythagorus to find the length of PM:

PM = [tex]\sqrt{3^{2} +8^{2} } =\sqrt{9 +64 }=\sqrt{73} =[/tex]8.544

Since PM is half PQ, PQ=2(8.544)=17.088
