Answer:

Discontinuities can be classified as jump, infinite, removable, endpoint, or mixed. Removable discontinuities are characterized by the fact that the limit exists. Removable discontinuities can be "fixed" by re-defining the function.

Answer:

x =  6/√3

y = 3/√3

Step-by-step explanation:

For a triangle rectangle with a known angle θ, we have the relations:

Sin(θ) = (opposite cathetus)/(hypotenuse)

Cos(θ) = (adjacent cathetus)/(hypotenuse)

Tan(θ) = (opposite cathetus)/(adjacent cathetus)

For this triangle, we know an angle:

θ = 60°

And the opposite cathetus measures 3 units.

The adjacent cathetus is y.

The hypotenuse is x.

To find the value of x, we can use the Sin equation:

Sin(60°) = 3/x

x = 3/sin(60°) = 3.46 = 3*2/√3 = 6/√3

And we can use the Tan relation to find the value of y.

Tan(60°) = 3/y

y = 3/Tan(60°) = 1.73 = 3/√3

For x he didn't divide by √3, while for y he multiplied by √3 instead of dividing by √3.

Answer:

3.333 hours

Step-by-step explanation:

Given the total distance is 30 miles, and boat 1 travels at 3 mph and boat 2 travels at 6 mph, and the time for both is the same. Distance is speed S times time T so

30 = D(boat 1) + D(boat 2)

30 = (S1 * T) + (S2 * T)

30 = 3T + 6T

30 = 9T

3.333 = T

Answer:

The 95% confidence interval estimate of the mean amount spent per day by a family of four visiting Niagara Falls is ($234.96, $269.94).

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

T interval

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 64 - 1 = 63

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 63 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 1.9983

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.9983\frac{70}{\sqrt{64}} = 17.49[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 252.45 - 17.49 = $234.96.

The upper end of the interval is the sample mean added to M. So it is 252.45 + 17.49 = $269.94.

The 95% confidence interval estimate of the mean amount spent per day by a family of four visiting Niagara Falls is ($234.96, $269.94).

Answer:

[tex]Length = 500ft[/tex]

[tex]Width = 250ft[/tex]

Step-by-step explanation:

Given

[tex]P = 1000[/tex] --- perimeter

Required

The dimensions that maximize the area

Let

[tex]L \to Length[/tex]

[tex]W \to Width[/tex]

Such that:

[tex]P = L + 2W[/tex] ---- Because one side is from the school building

This gives:

[tex]L + 2W = 1000[/tex]

Make L the subject

[tex]L = 1000 - 2W[/tex]

The area is then calculated as:

[tex]A= L * W[/tex]

Substitute: [tex]L = 1000 - 2W[/tex]

[tex]A= (1000 - 2W) * W[/tex]

Open bracket, then set A to 0

[tex]A = 1000W - 2W^2[/tex]

[tex]1000W- 2W^2 = 0[/tex]

Rewrite as:

[tex]-2W^2 + 1000W = 0[/tex]

Assume the form of the above equation is: [tex]aW^2 + bW + c = 0[/tex]

The value of W that maximizes it is:

[tex]W = -\frac{b}{2a}[/tex]

Where

[tex]a = -2[/tex]

[tex]b = 1000[/tex]

[tex]c = 0[/tex]

So:

[tex]W = -\frac{1000}{2*-2}[/tex]

[tex]W = \frac{1000}{2*2}[/tex]

[tex]W = \frac{1000}{4}[/tex]

[tex]W = 250[/tex]

Recall that:

[tex]L = 1000 - 2W[/tex]

[tex]L =1000 - 2 * 250[/tex]

[tex]L =1000 - 500[/tex]

[tex]L = 500[/tex]

So, the dimensions that maximize the area is:

[tex]Length = 500ft[/tex]

[tex]Width = 250ft[/tex]

Answer:

(4, 2)

Step-by-step explanation:

x = (x1 + x2 + x3)/3

x = (0 + 2 + 10)/3

x = 12/3

x = 4

y = (y1 + y2 + y3)/3

y = (6 + 0 + 0)/3

y = 6/3

y = 2

Answer:

Therefore, the value of the company is $ 1,000,000,000,000, that is, a trillion dollars. In turn, if the tangible assets of the company are worth 1 billion, all the other intangible assets of the company are worth 999 billion.

Step-by-step explanation:

Given that as of 2018, Apple had 5 billion outstanding shares whose stock price is roughly $ 200, to determine the value of the company and determine, if all tangible assets total $ 1 Billion, what represents the rest of Apple's worth, the following calculations must be done:

5 billion = 1,000,000,000

5,000,000,000 x 200 = X

1,000,000,000,000 = X

1 trillion = 1000 billions

1000 - 1 = 999

Therefore, the value of the company is $ 1,000,000,000,000, that is, a trillion dollars. In turn, if the tangible assets of the company are worth 1 billion, all the other intangible assets of the company are worth 999 billion.

Complete Question

A two-state system is in an environment at temperature 500 K. The energy of state 1 is[tex]E_1=4.1e-20 J[/tex], and the energy of state 2 is [tex]E_2= 5.7e-20 J[/tex]. Let P(1) be the probability of finding the system in state 1, and be the probability of finding the system in state 2. What is the ratio P(2)/P(1)

Answer:

 [tex]X=0.0984[/tex]

Step-by-step explanation:

From the question we are told that:

Temperature T=500 K

Energy of state 1 [tex]E_1=4.1e-20 J[/tex],

Energy of state 2 is [tex]E_2= 5.7e-20 J[/tex]

Generally the equation for Probability of finding the system in state is mathematically given by

 [tex]P(1)=e ^{\frac{-E_1}{KT}}[/tex]

Therefore

For Probability of finding the system in state 1 [tex]P(1)[/tex]

 [tex]P(1)=e ^{\frac{-E_1}{KT}}[/tex]

Where

   K is Boltzmann constant

   [tex]K=1.38*10^{-23}[/tex]

 [tex]P(1)=e ^{\frac{-(4.1e-20 J)}{1.38*10^{-23}*500}}[/tex]

For Probability of finding the system in state 1 [tex]P(2)[/tex]

 [tex]P(2)=e ^{\frac{-(5.7e-20 J)}{1.38*10^{-23}*500}}[/tex]

Generally the equation for The Ratio of [tex]P(2)[/tex] and [tex]P(2)[/tex] is mathematically given by

 [tex]X=\frac{P(2)}{p(1)}[/tex]

 [tex]X=e ^{\frac{E_1-E_2}{KT}}[/tex]

 [tex]X=e ^{\frac{-(4.1-5.7)e-20 J)}{1.38*10^{-23}*500}}[/tex]

 [tex]X=0.0984[/tex]

Answer:

x = 1

Step-by-step explanation:

So let me rewrite the problem so it looks better.

[tex]y=(\frac{2}{x-1}) + 1[/tex]

In math, division by zero is forbidden.

If you look, there is a division by an unknown value in the equation.

The excluded value must make x - 1 zero

x - 1 = 0

x = 1

1 is the excluded value.

Answer:

Amount of finance charge = $800

Interest rate = 5% per year

Step-by-step explanation:

Given:

Cost of item = $4,000

Per month payment = $100

Number of month = 48 month = 48 /12 = 4 year

Find:

Amount of finance charge

Interest rate

Computtaion:

Total amount pay = 100 x 48

Total amount pay = $4,800

Amount of finance charge = Total amount pay - Cost of item

Amount of finance charge = 4,800 - 4,000

Amount of finance charge = $800

Interest = P x r x T

800 = 4,000 x r x 4

800 = 16,000 x r

Interest rate = 5% per year
