Suppose that G(X) = F(x+ 9). Which statement best compares the graph of
G(x) with the graph of f(x)?

Answer:

  A.  2x² +12x

Step-by-step explanation:

If the mobile is balanced, the weights at each level are the same. Each of those in the lowest tier will be equivalent to 3x, for a total of ...

  4×3x = 12x

Each of those in the top tier shown will be equivalent to x², for a total of ...

  2×x² = 2x²

Then the sum of all parts will be ...

  top tier + bottom tier = 2x² +12x

The angle that subtends a chord is half the measure of the arc, so we have an arc QS of 2(84)=168 degrees.

Answer:

  C.)  f(x) = −4x + 200

Step-by-step explanation:

Since the number is decreasing, you know the slope will be negative, eliminating the first two choices. The equation in the last choice does not match the given data, so it can be eliminated.

In other words, the easiest way to solve this problem is to check the answers against the given data.

_____

If you want to write the equation from scratch, you need to find the slope. That is ...

  (change in number of cars)/(change in weeks) = (184 -192)/(4 -2) = -8/2 = -4

This matches only one answer, but you can go on to finish the equation by starting with point-slope form:

  y -192 = -4(x -2)

  y = -4x +8 +192 . . . . add 192, eliminate parentheses

  y = -4x + 200 . . . . matches choice C.)

Answer:

D 9 1/2

Step-by-step explanation:

5/(a+3) = 3/(a-2)

We can use cross products to solve

5 * (a-2) = 3 * (a+3)

Distribute

5a - 10 = 3a +9

Subtract 3a from each side

5a -3a -10 = 3a -3a +9

2a -10 =9

Add 10 to each side

2a -10+10 = 9+10

2a = 19

Divide each side by 2

2a/2 = 19/2

a = 19/2

a = 9 1/2

Answer:

  32°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the trig function relating angles to the opposite and adjacent sides of the triangle is ...

  Tan = Opposite/Adjacent

The side opposite the angle x is shown as having measure 5; the side adjacent has measure 8. Putting all this in the above equation gives ...

  tan(x) = 5/8

To find the angle from the value of the tangent, you use the inverse of the tangent function. The name of that is the arctangent function. It is often written as tan⁻¹(x) and often accessible on your calculator using a "second function" key. Some calculators, like the one shown in the attachment, recognize the arctan function name.

  x = arctan(5/8) ≈ 32°

The value of x rounded to the nearest whole degree is 32°.

Answer:

x = 4 or x = 1

Step-by-step explanation:

Solving absolute value equations can be a bit tricky.  Absolute values are actually distance measurements.  A very simple example is I x - 3 I = 2 says that "x is 2 units away from 3 on a number line".  2 units from 3 going to the right is 5, 2 units from 3 going to the left is 1.  So in other words, absolute value equations will have 2 answers, in this case 2 units to the right (+2) and 2 units to the left (-2).  That means that x - 3 = 2 OR x - 3 = -2.  Let's start to solve this one:

5I 2x - 5 I - 3 = 12

Start by adding 3 to both sides:

5I2x-5I = 15

Now divide both sides by 5:

I2x-5I = 3

We will set the left side equal to both +3 and -3 to get our 2 solutions:

2x - 5 = 3  and  2x - 5 = -3

Solving the first one for x:

2x = 8 and x = 4

Solving the second one:

2x = 2 and x = 1.

Fit these into the original absoute value statement and see if they are both true:

5I2(4)-5I-3=12 --> 5I3I - 3 = 12 and 15 - 3 = 12

5I2(1)-5I-3 = 12 --> 5I-3I - 3 = 12.  The absolute value of -3 is 3, so 15 - 3 = 12.  They both check out@

k+b=2

3k-k+b-b=0

2k=0

k=0

b=2

The equation is y=2

Answer: B is correct, y=2

Step-by-step explanation:

The formula for a line is y=mx+b, m is slope, and b is the y-intercept.

The line AB is completely flat, which means the slope is 0, so it won't show up in the equation. So right now we know the equation will be y=b. Now, we mist find b, the y-intercept. The line AB is crossing the y-axis at 2, meaning that's your y-intercept/b! The equation is y=2

Answer:

x = 39/74 - sqrt(1817)/74 or x = 39/74 + sqrt(1817)/74

Step-by-step explanation:

Solve for x:

(x - 4) (3 x - 2) - ((6 - 5 x) (x - 4) (8 x - 1))/(4 - x) = 0

Simplify and substitute y = 4 - x.

(x - 4) (3 x - 2) - ((6 - 5 x) (x - 4) (8 x - 1))/(4 - x) = -434 + 257 (4 - x) - 37 (4 - x)^2

= -37 y^2 + 257 y - 434:

-37 y^2 + 257 y - 434 = 0

Divide both sides by -37:

y^2 - (257 y)/37 + 434/37 = 0

Subtract 434/37 from both sides:

y^2 - (257 y)/37 = -434/37

Add 66049/5476 to both sides:

y^2 - (257 y)/37 + 66049/5476 = 1817/5476

Write the left hand side as a square:

(y - 257/74)^2 = 1817/5476

Take the square root of both sides:

y - 257/74 = sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74

Add 257/74 to both sides:

y = 257/74 + sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74

Substitute back for y = 4 - x:

4 - x = 257/74 + sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74

Subtract 4 from both sides:

-x = sqrt(1817)/74 - 39/74 or y - 257/74 = -sqrt(1817)/74

Multiply both sides by -1:

x = 39/74 - sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74

Add 257/74 to both sides:

x = 39/74 - sqrt(1817)/74 or y = 257/74 - sqrt(1817)/74

Substitute back for y = 4 - x:

x = 39/74 - sqrt(1817)/74 or 4 - x = 257/74 - sqrt(1817)/74

Subtract 4 from both sides:

x = 39/74 - sqrt(1817)/74 or -x = -39/74 - sqrt(1817)/74

Multiply both sides by -1:

Answer:  x = 39/74 - sqrt(1817)/74 or x = 39/74 + sqrt(1817)/74

Answer:

Step-by-step explanation:

Here we have to find out number of people attended the party. we are given with the number of the handshakes in the party .

We are going to use the following formula to determine the number of guests

Nos. of handshakes

[tex]H=\frac{1}{2}(n^2-n)[/tex]

Here we have H = 171

Hence our equation becomes

[tex]171=\frac{1}{2}(n^2-n)[/tex]

now we solve it by splitting the middle term method

[tex]171=\frac{1}{2}(n^2-n)\\2*171 =n^2-n\\n^2-n=342\\n^2-n-342=0\\[/tex]

Now we have to find the factors of 342 whose difference to 1. The factors are 19 and 18 in this case. hence we slit our middle term like this

[tex]n^2-n-342=0\\n^2-19n+18n-342=0\\n(n-19)+18(n-19)=0\\(n-19)(n+18)=0\\[/tex]

Hence

either

(x+18)=0 or (x-19) =0 Thus

x=-18 which is not possible as no of people can not be less than 0

x=19 which will our answer

b = 3

c = 6

Step-by-step explanation:

x^2 + 8x = 38

We take the coefficient of the x term

Divide by 2 and then square it

8/2 =4

4^2 = 16

Add 16 to both sides

x^2 +8x + 16 = 38 + 16

x^2 +8x +16 = 54

Take b/2 and use it in the the (x+b/2)^2

(x+4)^2 = 54

Take the square root of each side

sqrt((x+4)^2) = ± sqrt(54)

x+4 =  ± sqrt(54)

Subtract 4 from each side

x+4-4 = -4  ± sqrt(54)

x = -4  ± sqrt(54)

Simplify the square root

x = -4  ± sqrt(9*6)

x = -4 ± sqrt(9) sqrt(6)

x = -4 ± 3 sqrt(6)

Answer:

expected value

Step-by-step explanation:

Answer:

Expected value

Step-by-step explanation:

Expected value- Any discrete variable's expected value is probability-weighted average of all of its possible values.

In simple words, any possible value that can be inferred by the any given variable is compounded by its probability of occurrence and the resulting products are added up to deliver the expected value.

Answer:

The interest is: $1575

The total is: $8575

Step-by-step explanation:

7000*5*0.045 gets you the interest

Then you add the original amount, 7000, to the total

1575+7000=$8575

By using the Simple Interest formula (Principal * Rate * Time), we find that Jill will earn $1575 in interest over 5 years. Therefore, she will have $8575 in her account after 5 years.

To calculate how much Jill will have in her account after 5 years, we can use the simple interest formula, which is Principal * Rate * Time.

In Jill's case, the principal is the amount she initially deposited which is $7000. The rate is the simple interest rate offered by the bank annually, expressed as a decimal, so 4.5% becomes 0.045. The time is the number of years that the money remains in the account, which is 5 years.

By substituting these values into the formula, we have: $7000 * 0.045 * 5 = $1575.

This means the total interest Jill would earn over 5 years is $1575. The total amount in the account after 5 years would be the initial amount plus the interest, so $7000 + $1575 = $8575.

Answer:

b) The yellow rectangle was translated right 5 units and reflected over the x-axis.

d) The yellow rectangle was translated right 5 units and up 3 units.

Step-by-step explanation:

Translation in geometry describes a function that moves an object a certain distance without altering it. The object is not rotated, reflected or re-sized after translation. Every point of the object is moved in the same direction through the same distance.

Reflection is a rigid transformation in which the given object is flipped across a line to create its image. Each point of the image maintains their distance from the line as in the object. In reflection, every point of the object changes initial location.

The options that describe the transformation are: The yellow rectangle was translated right 5 units and reflected over the x-axis, and the yellow rectangle was translated right 5 units and up 3 units.

Answer:

  -3, 1, 4 are the x-intercepts

Step-by-step explanation:

The remainder theorem tells you that dividing a polynomial f(x) by (x-a) will result in a remainder that is the value of f(a). That remainder will be zero when (x-a) is a factor of f(x).

In terms of finding x-intercepts, this means we can reduce the degree of the polynomial by factoring out the factor (x-a) we found when we find a value of "a" that makes f(a) = 0.

__

For the given polynomial, we notice that the sum of the coefficients is zero:

  1 -2 -11 +12 = 0

This means that x=1 is a zero of the polynomial, and we have found the first x-intercept point we can plot on the given number line.

Using synthetic division to find the quotient (and remainder) from division by (x-1), we see that ...

  f(x) = (x -1)(x² -x -12)

We know a couple of factors of 12 that differ by 1 are 3 and 4, so we suspect the quadratic factor above can be factored to give ...

  f(x) = (x -1)(x -4)(x +3)

Synthetic division confirms that the remainder from division by (x -4) is zero, so x=4 is another x-intercept. The result of the synthetic division confirms that x=-3 is the remaining x-intercept.

The x-intercepts of f(x) are -3, 1, 4. These are the points you want to plot on your number line.

A. the first option is the correct answer.

Option A -  x > 50 and x < 150 Ryan needs to consume more than 50 grams of carbohydrates, but less than 150 grams of carbohydrates is the correct answer.

We have amount of carbs consumed in grams between the levels shown in the following compound inequality :

110 < 2x + 10

2x + 10 < 310

We have to solve for x in this inequality, and explain what the answer represents.

We can write the inequality as follows -

α < x < β (Since α is less then 0, it will be less then β)

According to question, we have -

110 < 2x + 10

110 - 10 < 2x + 10 - 10

100 < 2x

x > 50

2x + 10 < 310

2x + 10 - 10 < 310 - 10

2x < 300

x < 150

Hence, x > 50 and x < 150 : Ryan needs to consume more than 50 grams of carbohydrates, but less than 150 grams of carbohydrates.

Answer:

A

Step-by-step explanation:

She can type 3.75 words per second.

There are 60 seconds in a minute

Therefore she can type 3.75 * 60 = 225 words per minute.

If 1 page contains 675 words, it will take 675 // 225 words /min = 3 minutes

Therefore 25 pages will take 75 minutes (3 * 25 = 75)

75 minutes = 1 hour with 15 minutes left over.

Final answer:

The court reporter, typing at a minimum rate of 3.75 words per second, would have spent 1 hour and 15 minutes actively typing a 25-page trial transcript with an average of 675 words per page.

Explanation:

The question asks us to calculate the time a court reporter would have spent actively typing a transcript. To find this duration, we first determine the total number of words the trial transcript contains by multiplying the number of pages by the average number of words per page. Then, we divide the total number of words by the court reporter's typing speed in words per second to find the total time in seconds. Finally, we convert the total time from seconds into minutes and hours to get the answer in a more understandable format.

First, calculate the total number of words:

25 pages × 675 words per page = 16,875 words

Next, convert the court reporter's minimum typing speed into words per second:

3.75 words per second

Now, calculate the time spent typing:

Total time (in seconds) = Total number of words ÷ Words per second

Total time (in seconds) = 16,875 words ÷ 3.75 words/second = 4,500 seconds

Convert seconds to minutes: 4,500 seconds ÷ 60 = 75 minutes

Convert minutes to hours: 75 minutes ÷ 60 = 1.25 hours

Therefore, the court reporter was actively typing for 1 hour, 15 minutes, which corresponds to option A.

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

so...

y = -3x + 5

If lines are parallel then they have the same slope (m)

This means that the slope of the line will be -3

y = -3x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(0, 2)

2 = -3(0) + b

2 = 0 + b

2 = b

y = -3x + 2

Hope this helped!

~Just a girl in love with Shawn Mendes

In the equation y = mx + b, where m represents the slope and b represents the y-intercept, we can determine the slope of the line to be -3. When two lines are parallel, they have the same slope (m).

To find the value of b, we need to substitute the coordinates of a point the line passes through into the equation. In this case, the point is (0, 2).

By plugging in the values, we get:

2 = -3(0) + b

2 = 0 + b

Step-by-step explanation:

We are given the results of survey of one thousand families to determine the distribution of families by their size.

We are to find the probability (to the near percent) that a given family has more than 6 people.

Frequency of people with less than 5 people = 350 + 200 + 245 = 795

Total frequency = 1000

P (families with fewer than 5 people) = (795 / 1000) × 100 = 79.5% ≈ 80%
