Answer:

it would be 3 because if you list words then just divide 12 by 4 and you get 3

The number of the 4 letter words that can be made from a list of 12 letters will be 495.

Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.

Then the number of the 4 letter words can be made from a list of 12 letters will be

¹²C₄ = 12! / [(12 - 4)! x 4!]

¹²C₄ = 12 x 11 x 10 x 9 x 8! / 8! x 4 x 3 x 2 x 1

¹²C₄ = 11 x 5 x 9

¹²C₄ = 495

Answer:

The range of the function is [0 , ∞) ⇒ answer B

Step-by-step explanation:

* lets revise the meaning of the domain and the range

- The domain is the values of x

- The domain is all the values of x which make the function is defined

- If there are some values of x make the function undefined, we

 exclude these values from the domain

- The range is the values of f(x) which corresponding to the value of x

* Now lets look to the figure

∵ f(x) = √x

- We can not use the negative values for x because there is no

 square root for negative numbers

∴ All real negative numbers make the function undefined

- We must exclude them from the domain

∴ The domain is all real numbers greater than or equal zero

∴ x ≥ 0

- To find the range use the first value of the domain

∵ the first value of x = 0

∴ f(0) = √0 = 0

∵ x can not be negative

∵ f(x) = √x

∴ f(x) can not be negative

∴ the range is all real numbers greater than or equal zero

∴ f(x) ≥ 0

OR

f(x) = [0 , ∞)

* The range of the function is [0 , ∞)

Answer:

D) GE = 10 and GI = 12

Step-by-step explanation:

Given: KI = 4 and GH = 5

K is the centroid of EFG

So

KI = 1/3 (GI)

GI = 3 (KI) = 3(4) = 12

Because K is the centroid of EFG so GH = HE = 5

GE = GH + HE

GE = 5 + 5

GE = 10

Answer

GE = 10 and GI = 12

Answer:

D. GE = 10; GI = 12

Step-by-step explanation:

Given that K is the centroid of EFG, then GH = HE = 5, so GE = GH + HE = 5 + 5 = 10

The 2/3 rule states that the centroid is 2/3 of the way from the vertex to the opposite midpoint. This means that GK is doubled than KI, then GK = 2*4 = 8, and GI = GK + KI = 8 + 4 = 12

Answer:

D. [tex]y=3\cos \left(\dfrac{4}{3}x-2\pi\right)+2[/tex]

Step-by-step explanation:

The period of the functions [tex]y=\cos x,\ y=\sin x[/tex] is [tex]2\pi.[/tex]

The period of the function [tex]y=a\cos (kx+b),\ y=a\sin(kx+b)[/tex] is ALWAYS [tex]\dfrac{2\pi}{k}[/tex]

In your case, you have function [tex]y=-3\sin \left(\dfrac{2}{3}x-2\pi \right)+2[/tex] and this function has the period

[tex]\dfrac{2\pi}{\dfrac{2}{3}}=3\pi.[/tex]

You need to find the function that will have the period that is half of [tex]3\pi,[/tex] so

[tex]\dfrac{3\pi}{2}=\dfrac{2\pi}{k}\\ \\3k=4\\ \\k=\dfrac{4}{3}.[/tex]

So, correct choice is

[tex]y=3\cos \left(\dfrac{4}{3}x-2\pi\right)+2[/tex]

Answer:

The answer is y = 3 cos(4/3 x - 2π) + 2 ⇒ last answer

Step-by-step explanation:

* Lets revise the sine function

- If we have a sine function of the form f(x) = Asin(Bx + C) + D, where

 A, B , C and D are constant, then

# Amplitude is A

- The Amplitude is the height from the center line to the peak .

 Or we can measure the height from highest to lowest points and

 divide that by 2

# Period is 2π/B

- The period goes from one peak to the next

# phase shift is C (positive is to the left)

- The Phase Shift is how far the function is shifted horizontally  

 from the usual position.

# vertical shift is D

- The Vertical Shift is how far the function is shifted vertically from

 the usual position.

* Now lets solve the problem

∵ y = -3sin(2/3 x - 2π) + 2

- the period is 2π ÷ 2/3 = 2π × 3/2 = 3π

∴ The period of the function is 3π

- We look for a function has one-half (3π), means 3π/2

* Lets look to the answer to find the right one

- All of them have the same value of B except the last one, lets

 check it

∵ y = 3cos(4/3 x - 2π) + 2

∵ B = 4/3

∴ The period = 2π ÷ 4/3 = 2π × 3/4 = 6π/4 = 3π/2

∵ 3π/2 is half 3π

∴ The last answer is right

Answer:

Part 1)

a) The ratio of the heights of the similar solids is 5/1

b) The ratio of the surface areas of the similar solids is (5/1)²=25/1

c)  The ratio of the volumes of the similar solids is (5/1)³=125/1

Part 2) Two spheres with different radii measurements are always similar

Part 3) The volume of the sphere is greater than the surface area of the sphere

Step-by-step explanation:

Part 1) we know that

The ratio of the corresponding heights of the similar solids is equal to the scale factor

The ratio of the surface areas of the similar solids is equal to the scale factor squared

The ratio of the volumes of the similar solids is equal to the scale factor elevated to the cube

In this problem

The scale factor is 5/1

therefore

a) The ratio of the heights of the similar solids is 5/1

b) The ratio of the surface areas of the similar solids is (5/1)²=25/1

c)  The ratio of the volumes of the similar solids is (5/1)³=125/1

Part 2)

we know that

Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another.  

In this problem to prove that two spheres  are similar, a translation and a scale factor (from a dilation) will be found to map one sphere onto another.

therefore

Two spheres with different radii measurements are always similar

Part 3) The length of the diameter of a sphere is 8 inches

The volume of the sphere is equal to

[tex]V=\frac{4}{3}\pi r^{3}[/tex]

we have

[tex]r=8/2=4\ in[/tex] -----> the radius is half the diameter

substitute

[tex]V=\frac{4}{3}\pi (4)^{3}[/tex]

[tex]V=85.33\pi\ in^{3}[/tex]

The surface area of the sphere is equal to

[tex]SA=4\pi r^{2}[/tex]

substitute

[tex]SA=4\pi (4)^{2}[/tex]

[tex]SA=64\pi\ in^{2}[/tex]

therefore

The volume of the sphere is greater than the surface area of the sphere

Distance = speed + 90

The equation relates the distance she traveled to her speed is Speed x 90 = distance.

The speed a person travels is the total distance driven per the total time it took to travel.

Speed = total distance / total time

The time it took to drive is 90 minutes:  Speed = distance / 90

In order to determine the equation that relates distance to speed, make distance the subject of the formula. In order to do this, multiply both sides of the equation by 90: Speed x 90 = distance.

A polygon with six vertices is called a hexagon.

It is a two-dimensional figure with six sides and six angles. Hexagons are common in various real-life patterns and have properties like area and perimeter.

A polygon plotted on a coordinate plane with six vertices is known as a hexagon. A hexagon is a two-dimensional geometric figure with six angles and six sides.

Polygons are closed figures made up of straight line segments. When the polygon has six sides, it has interior regions and exterior regions that divide the plane it lies on. Each vertex connects two sides of the hexagon, forming angles at each vertex.

Answer:

Step-by-step explanation:

600 minus 399 is 201

The trip will take at least two days given the car's mileage limit per tank and the daily driving limit.

To determine how long a journey will take with the given constraints, we first need to understand the limitations. The car can run for 399 miles on one tank of gas, and the maximum you can drive in one day is fixed at 600 miles. Since the daily maximum driving distance is greater than the mileage per tank, the limiting factor is the gas tank range.

Assuming you start with a full tank, you would need to refill once you've driven 399 miles. If there is no wait time for refilling and the efficiency of the car does not change, you could potentially drive for another 399 miles after refilling. However, due to the 600 miles per day limit, you would need to stop before exhausting your second tank. To find out the total driving time, divide the total distance by the daily driving limit (if the total distance is larger than what can be covered in one day).

For example, if the total trip is 700 miles, it would take at least two days because you can cover 600 miles on the first day and the remaining 100 miles on the second day. However, this does not account for any potential stops, breaks, or other delays.
