Answer:

A transcendental number is a real number that is not the solution of any single-variable polynomial equation whose coefficients are all integers . All transcendental numbers are irrational numbers . But the converse is not true; there are some irrational numbers that are not transcendental.

Answer:

7.5 seconds

Step-by-step explanation:

[tex]h = - 16 {t}^{2} + 120t \\ \because \: we \: have \: to \: find \: the \: time \: required \: \\ for \: the \: object \: to \: return to \: its \: \\ point \: of departure. \\ \therefore \: plug \: h = 0 \: in \: the \: given \: euation. \\ \therefore \: 0 = - 16 {t}^{2} + 120t \\ \therefore \:16 {t}^{2} - 120t = 0 \\ \therefore \:8t(2t - 15) = 0 \\ \therefore \:8t = 0 \: \: or \: \: (2t - 15) = 0 \\ \therefore \:t = \frac{0}{8} \: or \: t = \frac{15}{2} \\ \therefore \:t = 0 \: or \: t = 7.5 \\ \because \: t = 0 \: is \: not \: possible \\ \huge \purple{ \boxed{ \therefore \: t = 7.5 \: seconds}}[/tex]

Thus, the time required for the object to return to its point of departure is 7.5 seconds.

Your question has been heard loud and clear.

If y = 3 , then 6y = 6(3) = 18

Thank you

Answer:

x = 6, y = -2, z = 0

Step-by-step explanation:

To find x, we have to plug 0 into f(x). Therefore, x = f(0) = 2 * 0² - 8 * 0 + 6 = 6. Similarly, to find y, we have to plug 2 into f(x) so y = f(2) = 2 * 2² - 8 * 2 + 6 = -2. Finally, z = f(3) = 2 * 3² - 8 * 3 + 6 = 0.

Answer:

4%

Step-by-step explanation:

Since she first goes down 20% you would do 3000 times 20 which is 60000 and divided by 100 which is 600 and you would subtract 600 from 3000 which is 2400 and then you would multiply that by 30 which is 72000 and then you would divide by 100 which is 720 and add that to 2400 which is 3120 and to find the percent change from 3000 to 3120 you would subtract 3120 by 3000 which is 120 and you would divide that by 3000 which is 0.04 and multiply that by 100 which is 4 so the percent change would be 4%

Its simple just calculate it in a calculator...

Answer:

A

Step-by-step explanation:

Add the number of decimal places of the two numbers being multiplied to know the number of decimal places of the product.

A: 3.48 x 42.37 = 147.4476

2 decimal places + 2 decimal places = 4 decimal places

Only choice A is correct.

Answer:

5.1 can be written as 51/10 (the quotient of the integers 51 and 10. So it is a rational number

Step-by-step explanation:

Recall that a rational number is a number that can be written as the quotient of two integer numbers.

In particular the number 5.1 can be written as 51/10 (the quotient of the integers 51 and 10. So it is a rational number.

Answer:

a

   No singular point due to the exponent in the solution

    The interval is   [tex]-\infty  <0 <  \infty[/tex]

b

   NONE

Step-by-step explanation:

From the question we are told that

     [tex]\frac{dy}{dx} =  9y[/tex]

The generally solution is mathematically represented as

         [tex]\frac{dy }{dx}  =  9y[/tex]

=>       [tex]\frac{dy}{y}  =  9dx[/tex]

integrating both sides  

         [tex]\int\limits  {\frac{ dy}{y} } \,  = \int\limits  {9} \, dx[/tex]

  =>   [tex]lny = 9x + c[/tex]

 =>   [tex]y =  e^{9x +c }[/tex]

 =>    [tex]y =  e^{9x} e^{c}[/tex]

Here [tex]e^c  =  C[/tex]

=>     [tex]y = C  e^{9x}[/tex]

From the above equation we see that the domain for x has no singular point the interval is

       [tex]-\infty  <0 <  \infty[/tex]

Also there is no transient term in the general solution obtained because as  [tex]x \to \infty[/tex] there no case where [tex]y \to 0[/tex]

Answer:

Purchase Price = $150 and Total Price = $162

Step-by-step explanation:

Purchase price = Tax Amount / Tax Percentage (as decimal)

Purchase Price = $12 / .08

Purchase Price = $150

Total Price = Purchase Price + Tax

Total Price = 150 + 12 = $162

Answer:

700 Minutes

Step-by-step explanation:

For this problem, we need to write an expression that represents the cost per the amount of time used for each phone plan, and set the two expressions equal to each other to find how many minutes would be needed for the costs to be equal.

For the first phone plan, we have a base $28 and additional $0.09 per minute of call.  This can be expressed as:

28 + 0.09x                  Where x is the number of minutes used

For the second phone plan, we have a flat $0.13 per minute of call.  This can be expressed as:

0.13x                           Where x is the number of minutes used

To find how many minutes would be used to make the cost equal, we simply set these expressions as equivalent, and solve for x.

28 + 0.09x = 0.13x

28 + 0.09x + -0.09x = 0.13x + -0.09x

28 = 0.04x

28 = (1/25)x

28 * 25 = (1/25)x * 25

28 * 25 = x

700 = x

Thus, for the cost of these phone plans to be equal, you would have to use 700 minutes per month.

Cheers.

Answer:

Option B. √x + 3

Step-by-step explanation:

f(x) = (x - 3)²

We can obtain the inverse f¯¹(x) of the above expression as follow:

f(x) = (x - 3)²

Replace f(x) with

f(x) = (x - 3)²

y = (x - 3)²

Next, interchange x and y

y = (x - 3)²

x = (y - 3)²

Make y the subject

x = (y - 3)²

Take the square root of both side

√x = y - 3

Add 3 to both side

√x + 3 = y - 3 +3

√x + 3 = y

y = √x + 3

Finally, replace y with f¯¹(x)

y = √x + 3

f¯¹(x) = √x + 3

Answer:

Step-by-step explanation:

1. Subtract 9:

  -10 < n < 8

__

2. Add 12, then divide by 8:

  10 < 8x ≤ 48

  10/8 < x ≤ 6

  5/4 < x ≤ 6 . . . . . with the fraction reduced

_____

The rules of equality allow us the do these operations, provided that we do them to all parts of the compound inequality. That is, when we say "subtract 9", we mean ...

  -1 -9 < 9 +n -9 < 17 -9

This simplifies to the inequality we show above:

  -10 < n < 8

Answer:

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = ((- 2, 3) and (x₂, y₂ ) = (4, 1)

m = [tex]\frac{1-3}{4+2}[/tex] = [tex]\frac{-2}{6}[/tex] = - [tex]\frac{1}{3}[/tex] , thus

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 3), then

3 = [tex]\frac{2}{3}[/tex] + c ⇒ c = 3 - [tex]\frac{2}{3}[/tex] = [tex]\frac{7}{3}[/tex]

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{3}[/tex] ← equation of line

b

[tex]0.3498 < p < 0.4089[/tex]

c

 With the result obtained from a and b the manager can be 95 % confidence that the proportion of the population that complained about dirty or ill-equipped bathrooms are within the interval obtained at  a

and that

the proportion of the population that complained about loud or distracting diners at other tables are within the interval obtained at  b

Step-by-step explanation:

From the question we are told that

The sample size is  [tex]n = 1003[/tex]

The number that complained about dirty or ill-equipped bathrooms is [tex]e = 732[/tex]

 The number that complained about loud or distracting diners at other tables is  [tex]q = 381[/tex]

Given that the the confidence level is  95% then the level of significance is mathematically represented as  

         [tex]\alpha = (100- 95)\%[/tex]

         [tex]\alpha = 0.05[/tex]

Next we obtain the critical value of  [tex]\frac{\alpha }{2}[/tex] from the normal distribution table , the value is  

         [tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]

Considering question a

The sample proportion is mathematically represented as

           [tex]\r p = \frac{e}{n}[/tex]

=>        [tex]\r p = \frac{732}{1003}[/tex]

=>        [tex]\r p = 0.73[/tex]

Generally the margin of error is mathematically represented as

          [tex]E = Z_{\frac{\alpha }{2} } * \sqrt{ \frac{ \r p (1- \r p)}{n} }[/tex]

          [tex]E = 1.96* \sqrt{ \frac{ 0.73 (1- 0.73)}{1003} }[/tex]

          [tex]E = 0.01402[/tex]

The 95% confidence interval is  

        [tex]\r p - E < p < \r p +E[/tex]

        [tex]0.73 - 0.01402 < p < 0.73 + 0.01402[/tex]

        [tex]0.716 < p < 0.744[/tex]

Considering question b

The sample proportion is mathematically represented as

           [tex]\r p = \frac{q}{n}[/tex]

=>        [tex]\r p = \frac{381}{1003}[/tex]

=>        [tex]\r p = 0.3799[/tex]

Generally the margin of error is mathematically represented as

          [tex]E = Z_{\frac{\alpha }{2} } * \sqrt{ \frac{ \r p (1- \r p)}{n} }[/tex]

          [tex]E = 1.96* \sqrt{ \frac{ 0.3799 (1- 0.3799)}{1003} }[/tex]

          [tex]E = 0.0300[/tex]

The 95% confidence interval is  

        [tex]\r p - E < p < \r p +E[/tex]

        [tex]0.3798 - 0.0300 < p < 0.3798 + 0.0300[/tex]

        [tex]0.3498 < p < 0.4089[/tex]
