Answer: The graph is shifted 6 units to the right.

Step-by-step explanation:

It is important to remember that:

When [tex]f(x-k)[/tex], then the function is shifted "k" units to the right.

Knowing this and given the quadratic parent function [tex]y=x^2[/tex] and the function [tex]y-1=\frac{1}{2}(x-6)^2[/tex], you can observe that one of the transformations is the following:

[tex]f(x-k)[/tex]

Where:

[tex]k=6[/tex]

Therefore, you can notice that the effect is:

The graph is shifted 6 units to the right.

Answer:

1/26

Step-by-step explanation:

There's only 1 four of spades and only 1 six of diamonds.  So the probability is:

P = P(4 of spades) + P(six of diamonds)

P = 1/52 + 1/52

P = 1/26

The probability of selecting the four of spades or the six of diamonds from a standard 52-card deck is 1/26. This is determined by adding the probabilities of each individual card being drawn since they are mutually exclusive events.

The question asks about the probability of selecting a specific card from a standard 52-card deck. To find the probability of selecting either the four of spades or the six of diamonds, we recognize that these are two distinct events. Since there is one four of spades and one six of diamonds in a deck, and there are 52 cards in total, the probability of drawing the four of spades is 1/52 and similarly the probability of drawing the six of diamonds is also 1/52. These events are mutually exclusive, meaning they cannot happen at the same time, so we can simply add the two probabilities together to find the total probability:

Probability(four of spades or six of diamonds) = Probability(four of spades) + Probability(six of diamonds) = 1/52 + 1/52 = 2/52.

Therefore, the probability is 2/52, which can be simplified to 1/26.

Answer:

32

Step-by-step explanation:

The face closest to us has 4 by 4 unit cubes which is 16 cubes.

There are 2 faces deep in the cubiod so the total is 32 unit cubes.

Answer:

The size of the cuboid is 32, or approximately 5.66 squared.

Step-by-step explanation:

First, find the dimensions of the cuboid.

(4)(4)(2)

Next, multiply the numerics (the values).

(4x4)x2 = 16x2 = 32

The cuboid's volume is 32, or about 5.66 squared.

Answer: I think the answer is the second box.

Step-by-step explanation: It says 20 males have watched the show. I hope I helped you. If I am wrong, tell me in a polite way. :D

Hello there! The answer is the second chart, or B.

To find the answer, look at the parts of the question.

Let's start in the beginning. Note how it says "Of the 80 participants, 30 were male and 50 were female". This means that, looking at the options, in the "total" row, there should be a value for "30" by male, "50" by female and 80 at the bottom. This means that it cannot be A since this option says that there were 80 females and 80 males and 160 total, or C since it says there are 80 males and 55 females with a total of 135.

Next, it says that 45 have watched the show and 35 have not. If you look at the options left B and D, the only one the has these numbers for have and have not watched is B, making this the correct answer.

I hope this helps and have a great rest of your day! :)

The volume is (area of cross-section) x (length) .

-- The cross-section is a triangle.  The area of a triangle is

Area = (1/2) (base) (height) .

In this one, the base is 9/4 m and the height is 3-1/3 m .

Area = (1/2) (9/4 m) (3-1/3 m)

Area = (1/2) (9/4) (10/3)

Answer: X = 8 And Y = 5 "First Choice Letter A"

Step-by-step explanation: x + y = 13......x = 13 - y

2x - 3y = 1

2(13 - y) - 3y = 1

26 - 2y - 3y = 1

-2y - 3y = 1 - 26

-5y = -25

y = -25/-5

y = 5

x + y = 13

x + 5 = 13

x = 13 - 5

x = 8

The statement that is always true is that supplementary and complementary angles are always adjacent angles.

The statement that is ALWAYS TRUE is (C) Supplementary and Complementary angles are always adjacent angles. Supplementary angles are two angles that add up to 180 degrees, while complementary angles are two angles that add up to 90 degrees. Adjacent angles are two angles that have a common vertex and a common side between them. So, it is always true that supplementary and complementary angles are adjacent angles because they share a common side.

Answer:

Degree: 5

Y-intercept: 12

Step-by-step explanation:

The given expression is

[tex]f(x)=-(x+1)^2(2x-3)(x+2)^2[/tex]

Since the factors are multiplying, we can analyse the degree of each factor and add them to find the degree of the polynomial.

The degree of the factor [tex]-(x+1)^2[/tex] is 2.

The degree of [tex](2x-3)[/tex] is 1

The degree of [tex](x+2)^2[/tex] is 2

Therefore the degree of the polynomial is 2+1+2=5

To find the y-intercept, we put x=0.

THis is false.

b.

We know 1 feet is 0.30 meters, so definitely 1 foot is less than 1 meter.

This is true.

c.

we know around 28.35 grams is 1 ounce, so definitely 25 grams is less than 1 ounce.

THis is true.

If Mr. Cooper decides to make a new scale drawing of the play set, in which he uses a scale of inch = 1 foot, all of the dimensions in the old drawing will be multiplied by a factor of ⇒ the last answer

Step-by-step explanation:

* Lets study what is the meaning of the scale factor

- To find a scale factor between two similar figures

# Find two corresponding sides and write the ratio of the two sides.

# If you begin with the smaller figure, your scale factor will be less

  than one.

# If you begin with the larger figure, your scale factor will be greater

  than one

* Now lets solve the problem

- The rectangular sandbox, has a length of 5 feet and a width of

  7 feet

- On the scale drawing, the length of the sandbox is 2 inches

- The actual sandbox and the drawing sandbox are similar

∵ The length of the actual sandbox is 5 feet

∵ The drawing length is 2 inches

∵ 1 foot = 12 inches

∴ The scale factor is 2/(5 × 12) = 1/30

* That means each actual dimensions will multiply by 1/30 to find

  the drawing dimensions

∴ The drawing length of the sandbox = 5 × 12 × 1/30 = 2 inches

∴ The drawing width of the sandbox = 7 × 12 × 1/30 = 2.8 inches

* All of the dimensions in the old drawing will be multiplied by

 a factor of 1/30

Answer:

-23

Step-by-step explanation:

Each term is 6 less than the past term. Hopw this helps!

There is no "standard" way to solve an exercise like this: you just have to eyeball the sequence and try to find/guess the pattern.

The most common (and easy!) examples are arithmetic or geometric sequence, where the difference or ratio between two consecutive terms is constant.

This is one of those cases: this is an arithmetic sequence, because you obtain every next term by subtracting 6 from the previous one:

[tex]a_1 = 7\\a_2 = a_1-6 = 7-6 = 1\\a_3 = a_2-6 = 1-6 = -5\\a_4 = a_3-6 = -5-6 = -11\\a_5 = a_4-6 = -11-6 = -17[/tex]

So, we can deduce

[tex]a_6 = a_5-6 = -17-6 = -23[/tex]

The measure of angle LMW is [tex]m\angle LMW=67\°[/tex]

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc MW

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m\angle MLK=\frac{1}{2}[arc\ MW+arc\ WK][/tex]

substitute the given values

[tex]65\°=\frac{1}{2}[arc\ MW+68\°][/tex]

[tex]130\°=[arc\ MW+68\°][/tex]

[tex]arc\ MW=130\°-68\°=62\°[/tex]

step 2

Find the measure of arc LK

we know that

[tex]arc\ LM+arc\ MW+arc\ WK+arc\ LK=360\°[/tex] -----> by complete circle

substitute the given values

[tex]164\°+62\°+68\°+arc\ LK=360\°[/tex]

[tex]294\°+arc\ LK=360\°[/tex]

[tex]arc\ LK=360\°-294\°=66\°[/tex]

step 3

Find the measure of angle LMW

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m\angle LMW=\frac{1}{2}[arc\ LK+arc\ WK][/tex]

substitute the given values

[tex]m\angle LMW=\frac{1}{2}[66\°+68\°]=67\°[/tex]

Applying the inscribed angle theorem, the measure of angle LMW is found as: 67°.

According to the inscribed angle theorem, the measure of an inscribed angle is half the measure of the arc that is intercepted.

Given:

Find m(MK):

m(MK) = 2(m∠MLK) (inscribed angle theorem)

Substitute

m(MK) = 2(65°)

m(MK) = 130°

Find m(LK):

m(LK) = 360° - m(LM) - m(MK) (full circle)

Substitute

m(LK) = 360° - 164° - 130°

m(LK) = 66°

Therefore:

m∠LMW = 1/2[m(LK) + m(WK) (inscribed angle theorem)

Substitute

m∠LMW = 1/2[66° + 68°]

m∠LMW = 1/2[134°]

m∠LMW = 67°

Making T subject of the formulae

T²=A³.............................square root both sides

T= √A³ OR    (A³)^1/2

if  the orbital period of planet Y is twice the orbital period of planet X then,

Y=2T

Y=2× √A³
