Answers

Answer 1

New location of a particle moves in a velocity field at time 6.01 is given by: (7.49, 2.11).

What is a velocity field?

Think about the fluid flow's steady-state velocity vector field, or v. The instantaneous velocity of the fluid particles (atoms or molecules) as they pass through the point (x,y) is measured by the vector v(x,y).

The vector field used to quantitatively characterize the motion of a continuum in continuum mechanics is called the flow velocity in fluid dynamics, macroscopic velocity in statistical mechanics, or drift velocity in electromagnetism. The flow speed is a scalar and is represented by the length of the flow velocity vector.

It is also known as a velocity field, and a velocity profile is what it is known as when it is measured along a line.

Everything about a fluid's motion is efficiently described by its flow velocity.

Bronson is creating a right triangular flower bed. If two of the sides of the flower bed are 7 feet long each, what is the length of the third side to the nearest foot?

Answers

The length of the third side of the right triangular flower bed is 10 feet.

A right-angled triangle is a triangle with one of its interior angles equal to 90°. The side opposite to the right angle is the largest side and is referred to as the hypotenuse. Hypotenuse is always greater than any of the other two sides.

If two of the sides of the flower bed are 7 feet long each, then these are the sides adjacent to the right angle. We are to find the length of the third side, which is the hypotenuse, using the Pythagorean theorem.

Pythagorean Theorem states that the square of the length of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the two other sides.

c^2 = a^2 + b^2

where a and b are the adjacent sides to the right angle

c is the hypotenuse

c^2 = 7^2 + 7^2

c^2 = 49 + 49

c^2 = 94

c = 9.899

Hence, he length of the third side of the right-angled triangular flower bed is 10 feet.

x-y=4 et xy=21 calculer x^3-y^3

Answers

Answer:

316 or -316.

Step-by-step explanation:

x^3 - y^3 = (x - y)(x^2 + xy + y^2)

               = 4(x^2 + y^2 + 21)

x - y = 4

xy = 21

Substitute x = 4 + y in the last equation

(4 + y) y = 21

y^2 + 4y - 21 = 0

(y + 7)(y - 3) = 0

y = 3, -7.

So, x = 7, - 3.

So,  x and y are 7 and 3 or -7 and -3.

But x^2 + y^2 = 9 + 49 = 58 whichever is true,

So, x^3 - y^3

= 4(x^2 + y^2 + 21)

= 4 (58 + 21)

= 316,

If x = -3 and y = -7 , then the answer is

-316.

Write an equation of each line in point-slope form.
(0,0) and (-4,-5)

Answers

The equation of the line in point-slope form, which passes through the pair of points located at (0 , 0) and (-4 , -5), is y + 5 = 5/4(x + 4).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Getting the slope of the two points: (0 , 0) and (-4 , -5)

m = (y2 - y1)/(x2 - x1)

m = (-5 - 0)/(-4 - 0)

m = -5/-4

m = 5/4

Using the point slope form, plug in the values of the slope and Point A to set up the equation.

(y - y1) = m(x - x1)

where m = 5/4 and (x1 , y1) = (-4 , -5)

(y - -5) = 5/4(x - -4)

y + 5 = 5/4(x + 4)

How is -89 represented using 8-bit two's compliment? (the answer should be 8 binary digits)

Answers

-89 can be represented by using 8-bit two's compliment as 10100111.

What is binary encoding?

Binary encoding can be defined as a standard technique that is designed and developed to convert data in plain text (source alphabets) to a form that is easily used by different operating systems (OS), especially through the use of a binary digit (bit) or two-symbol system.

In Computer programming, two's complement of base-10 is generally easier to implement because it has a single representation of 0 only.

How to convert a binary (base-10) to decimal (base-2)?

First of all, we would determine the positive version of -89, which is 89:

2 | 89

2 | 44 R 1

2 | 22 R 0

2 | 11 R 0

2 | 5 R 1

2 | 2 R 1

2 | 1 R 0

2 | 0 R 1

Next, you would read the decimal number (base-2) upward and this gives:

89₂ = 01011001.

For the negative integer number representation on 8-bits, we would replace all the 0s with 1s and the 1s with 0s as follows:

01011001 = 10100110

For the 8-bit two's complement, we would add 1 to the above number:

-89 = 10100110 + 1

-89 = 10100111.

An airplane on a long-distance flight flew the first 1295 miles of it's journey on 3 hours and 33 minutes. After that, the wind changed, and it took the plane 1 hour and 47 minutes to cover the remaining 738 miles. What was the plane's average speed during the flight?

Round to the nearest tenth

Answers

The plane's average speed during the flight is 381.43 miles per hour.

What is the average speed?

The average speed is the quotient of the total distance covered during the flight divided by the total time used.

The Average Speed is the scalar quantity that shows the rate of change in displacement from one point to another.

Data and Calculations:

The distance for the first miles = 1,295 miles

The time it took the plane to cover the distance = 3 hours 33 minutes

The distance for the last lap = 738 miles

The time it took the plane to cover the last distance = 1 hour 47 minutes

The total distance covered for the journey = 2,033 miles (1,295 + 738)

The total time for the journey = 5 hours 20 minutes or 5.33 hours

Average Speed = 2,033/5.33

= 381.43 miles per hour

Thus, the plane's average speed during the flight is 381.43 miles per hour.

The function that represents the Transformation of the graph is  F(X+1/2).

Different non-vertical lines have different slopes and/or y-intercepts. They are graphs of various linear functions. If there are two such lines, one can be considered a transformation of the other. There is a group of functions called the family, each function being a transformation of a special function called a parent. Linear functions form a series of functions. All linear functions are transformations of the function y = x. The function y = x is an upper linear function. Each family role is a transformation of a parent's role. The conversion type is translation. A translation moves the graph of the parent function horizontally, vertically, or both without changing shape or orientation.

In the other words if the polygon has the point within the angle it is in the interior of the angle , but if the point is outside then is it said to be in the exterior of the angle.

What is Non adjacent interior angle ?

Non adjacent angles are those angles which are not adjacent to each other. The non adjacent angles follow one of the  properties which are listed below:

They do not share a common vertex or common side.They can share a side, but not share the common vertex.They share a common vertex, but not share the common side.

In the given question,

taking a example say a triangle ABC with  ∠A=64,  ∠B = 45 and an external angle x to the side AC.

as sum of angles equal to 180

thus,  ∠A +  ∠B +  ∠C = 180

         64 + 45 +  ∠C = 180

          ∠C = 180-109 = 71

now as x is external to  ∠C,

therefore x = 180 -  ∠C = 180 - 71

                x = 109 =  ∠A +  ∠B

Which describes the pilot’s distance in section i? zero constant decreasing increasing

Answers

The pilot's distance is increasing.

In the graph, we can see distance on y axis and time on x axis. It is clearly visible that at 2 minutes, the distance covered is 0.4 miles. Further, at 4 minutes, the distance covered increases to 0.8 miles. At 6 minutes, the distance covered again increases by 0.4 miles and is 1.2 miles. At 8 minutes, the distance covered in 1.6 miles, which again increases by 0.4.

Now, it is evident that distance is increasing.

We can further calculate the speed using given information -

Speed = distance/time

Total distance = 1.6 - 0.0

Total distance = 1.6 miles

Total time = 8 - 0

Total time = 8 minutes

Speed = 1.6/8

Speed = 0.2 miles per minute.
