The big-o time analysis for the combined time of attaching all n numbers i O(n).

The big-O running time gives the relationship between the steps taken for the algorithm and its running time. it is denoted by O(.), where . refers to the some f(n). f(n) is determined by the way of the algorithm in each step.

Here, we attach 1, then 2,then 3 and so on up to n to make a sequence of numbers. So at a time, only 1 number is attached and therefore one step of the algorithm is working. So we can say that the big-O time analysis for the combined time of attaching all n numbers is O(n).

This means that at n = 1, only 1 step is taken by the algorithm .At n=2, two steps and continued like this up to n steps.

The expression (8x+64) can be rewritten as a common factor as 8(x+8).

According to the question,

We have the following expression:

(8x+64)

It is to be noted that a common factor is such a number including a variable that it can completely divide a term. For example, in this expression, 8 is such a number that it can divide both 8x as well as 64.

(This can be better understood using more examples. For example, 4 is a common factor in 4x+24 and 5 is a common factor in 5x+30.)

Now, taking 8 as a common factor:

8 (x+8)

Hence, the correct expression is D (the fourth one).

Answer:

x= 32

Step-by-step explanation:

3x-2+3x-10= 180 (sum of angles in straight line)

6x-12=180

6x=192

6x/6= 192/ 6

x = 32

Step-by-step explanation:

3x - 2 ° + 3x - 10° = 180°

reason : being angle in linear pair ...

6x - 12 = 180°

6x = 180° + 12

6x = 192°

[tex] x = \frac{192}{6} \\ [/tex]

x = 32°

Now ,

3x - 2 °

= 3 × 32 - 2

= 96 - 2

= 94°

Again ,

= 3x - 10°

= 3 × 32 - 10°

= 86°

The measure of angle A in the triangle is 18°

The angles in the triangle are given as:

m∠A = (2x − 24)°, m∠B = (x + 8)°, m∠C = (4x + 49)°

The sum of angles in a triangle is 180

So, we have

m∠A + m∠B + m∠C = 180

Substitute the known values in the above equation

So, we have:

2x − 24 + x + 8 + 4x + 49 = 180

Evaluate the like terms

7x = 147

Divide both sides by 7

x = 21

Substitute x = 21 in m∠A = (2x − 24)°

m∠A = (2 * 21 − 24)°

Evaluate

m∠A = 18°

Hence, the measure of angle A in the triangle is 18°

If a quadrilateral is a square, then it is a rectangle.                                  True

With four sides, four vertices, and four angles, a quadrilateral is a closed shape and a specific kind of polygon. Four non-collinear points are connected to produce it. A quadrilateral's internal angles add up to 360 degrees in all cases.

The Latin words "Quadra" for four and "Latus" for "sides" are combined to get the English word quadrilateral. A quadrilateral need not have equally long sides on all four sides. So, depending on the sides and angles, we can have many quadrilateral forms.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that someone has a net worth of 7.92×10¹⁰.Suppose that this individual now decides to give one-eighth of a percent of his new net worth to charity.

The number of dollars given to the charity will be calculated as below:-

Networth: 7.92 × 10¹⁰.

The percentage given to the charity is:-

1/8 %= 0.125 % = 0.00125 × networth

The number of dollars given to the charity is:-

Number of dollars = 0.00125 × 7.92 × 10¹⁰.

Number of dollars = $99,000,000.

Therefore, the number of dollars given to the charity will be $99,000,000.

Answer:

In points (1,2), 1 is the value of X which represents Time in Hours and 2 is the value of Y which means Cost or $ per hour for the duration of the parking in the lot. I hope this helps.

Step-by-step explanation:

i.  The equipment elevator is at a depth of 270 feet (-270 feet), while the miners elevator is at a depth of 180 feet (-180 feet) below the surface.

ii. The equipment elevator is deeper than that of the miners elevator.

The speed of an object is the rate at which the object moves.

speed = distance / time.

Thus,

Speed of the equipment elevator = 6 feet per second

Speed of the miners elevator = 15 feet per second.

Time of descent of the equipment elevator = 33 + 12

                                                                   = 45 seconds

So that, the distance of the elevator at this time is;

⇒ distance = speed x time

                  = 6 x 45

                   = 270 feet

 distance = - 270 feet

The distance of the miners elevator after 12 seconds is:

⇒ distance = speed x time

                  = 15 x 12

                  = 180 feet

distance = - 180 feet

Thus after another 12 seconds, the equipment elevator is at a depth of 270 feet (-270 feet), while the miners elevator is at a depth of 180 feet (-180 feet) below the surface.

Therefore, the equipment elevator is deeper than that of the miners elevator.

The circumference of the given circle is: 16πcm.

All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.

Given: Area of a circle = 64π cm²

To find: Circumference of the circle.

Finding:

We know that the formula of the area of a circle = πr²,

On comparing it with the given value, we get:

πr² = π(64)

πr² = π(8)²

8² = r²

r = 8cm (as the side of a circle can never be negative).

Also, the formula of the circumference of a circle = 2πr

Thus, for the circle having radius 8 cm, circumference = 2π(8) = 16πcm.

Hence, The circumference of the given circle is: 16πcm.

average inflation rate of cold drink will be 100%

Inflation is the term used to describe an increase in the price of goods and services that households buy. It is determined by how quickly these prices fluctuate. Prices frequently rise with time, but they can also fall (a situation called deflation).

You will subtract the starting price (A) from the later price (B), and divide it by the starting date (A). Then multiply the result by 100 to get the inflation rate percentage.

FORMULA FOR FINDING AVERAGE INFLATION = ((B-A)/A)*100

The unit rate in minutes per meter is 12½ min./m if it takes 15 over 2 minutes to fill an empty aquarium to a depth of 3 over 5 meters.

It takes 15/2 mins to fill an empty aquarium to a depth of 3/5 meters.

In a situationism like this we can make a equation such as

15/2 = 3/5

Lets multiply 5 in both sides

15/2 × 5= 3/5 × 5

75/2 = 3

Now lets divide both sides with 3

(75/2)/3 =3/3

25/2 = 1

Thus, the unit rate in minutes per meter is 12½ min./m if it akes 15 over 2 minutes to fill an empty aquarium to a depth of 3 over 5 meters.

Which car goes faster, a car that travels 42 miles in three hours or a car that travels 132 miles in seven hours? The solution is determined by the unit rate of each automobile. Rather than comparing the distances traveled in two or seven hours, compare how far each car drives in one hour.

A unit rate is just a ratio of two unit values, with the denominator always being one. This enables easy comparison of data values.
