Why are arithmetic sequences discrete data?

Answers

Answer:

If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.

Step-by-step explanation:

Answer:

A sequence is a discrete structure used to represent an ordered list.

Step-by-step explanation:

Discrete values are values between the terms if the sequences are not included in the sequence. If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So in that sense, yes, sequences are discrete. A sequence is a discrete structure used to represent an ordered list. A sequence is a function from a subset of the set of integers (usually either the set {0,1,2,. . .} or {1,2, 3,. . .}to a set S. We use the notation an to denote the image of the integer n. We call an a term of the sequence.

Rectangle ABCD is congruent to rectangle HGJK.

Rectangles A B C D and H G J K are shown. The length of A B is 11 inches. The length of K H is 18 inches.

What is the area of rectangle ABCD?

square inches

Answers

Answer:

It is 198

Step-by-step explanation:

(Width)(Height)

mutliply (11) times (18)

The area of rectangle ABCD is 198 square inches

The given parameters are:

[tex]\mathbf{AB = 11}[/tex]

[tex]\mathbf{KH = 18}[/tex]

Because the rectangles are congruent, then:

[tex]\mathbf{HG = AB = 11}[/tex]

[tex]\mathbf{KH = DA= 18}[/tex]

So, the area of rectangle ABCD is the product of side lengths AB and DA

So, we have:

[tex]\mathbf{Area = AB \times DA}[/tex]

Substitute values for AB and DA

[tex]\mathbf{Area = 11 \times 18}[/tex]

[tex]\mathbf{Area = 198}[/tex]

Hence, the area of rectangle ABCD is 198 square inches

The surface area of a sphere is π sq.cm.If it's radius is doubled,by how much does its surface area increase?​

Answers

Answer:

Doubling the radius of a sphere will increase its surface area 4 times

Step-by-step explanation:

The surface area of a sphere with radius r is given by the formula:

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

Doubling the radius means: r=> 2r

Putting the new radius the new surface area will be:

[tex]SA_1 = 4\pi (2r)^2\\SA_1 = 4\pi (4r^2)\\SA_1 = 4(4\pi r^2)\\SA_1 = 4(SA)[/tex]

The new surface area with double radius is 4 times of the old surface area with r.

Hence,

Doubling the radius of a sphere will increase its surface area 4 times

Determine if the following argument always applies, sometimes applies, or never applies. Provide at least 2 examples in your explanation.

"The sum of a number and its opposite is always 1."

Answers

Answer:

Never applies

Step-by-step explanation:

Given

Argument: The sum of a number and its opposite is always 1

Assume a positive number x

The opposite of the number is negative x (i.e. -x)

The sum of both numbers is:

[tex]Sum = x + (-x)[/tex]

Open Bracket

[tex]Sum = x -x[/tex]

[tex]Sum = 0[/tex]

Now, take for instance.

[tex]Number = 5[/tex]

Opposite would be

[tex]Opposite = -5[/tex]

Their sum is:

[tex]Sum = 5 + (-5)[/tex]

[tex]Sum = 5 -5[/tex]

[tex]Sum = 0[/tex]

Another instance is:

[tex]Number = -8[/tex]

Opposite would be

[tex]Opposite = 8[/tex]

Their sum is;

[tex]Sum = -8 + 8[/tex]

[tex]Sum = -0[/tex]

Hence, the argument never applies because the sum is never 1

How long will it take an investment to double in value if the interest rate is 6% compounded continuously

Answers

Answer:

11.55 years

Step-by-step explanation:

Formula to calculate the final value when the money is compounded continuously is,

Final value = [tex]\text{(Present value)}.e^{rt}[/tex]

Here 'r' = rate of interest

t = duration for the investment

Let the money invested = $x

We have to find the duration in which the present value gets doubled.

Final value = $2x

Rate of interest = 6% per year ≈ 0.06

By substituting these values in the formula,

[tex]2x=x.e^{0.06t}[/tex]

[tex]2=e^{0.06t}[/tex]

ln(2) = [tex]\text{ln}e^{0.06t}[/tex]

0.693147 = 0.06t

t = 11.55 years

Therefore, invested amount will be doubled in 11.55 years.

Arthur Zimmermann had no idea that "Blinker" Hall had read his secret message. But now that Hall had read it, what could he do with this information? On one hand, he believed that President Wilson, faced with the information in the telegram, would declare war on Germany. On the other hand, to share the telegram with Wilson would surely alert Berlin that the British had been reading their secret messages. As he walked back to his office, Hall considered ways that he could share the intelligence in the Zimmermann telegram and establish its authenticity without letting Berlin know that Room 40 had intercepted and read hundreds of their secret messages. Why was Hall concerned that the Germans would learn about the British reading their secret messages? The Germans would begin reading British secret messages to get revenge. Reading an enemys secret messages is against the codes of war. The Germans would then find a different way of transmitting their messages. This knowledge would make the Americans sympathize with the Germans.
