The value of the line integral ∫Cxe^{yz}ds is approximately  8.645×10⁻⁵.

Given the line integral ∫Cxe^{yz}ds, where C is the curve r(t) = (t, 2t, -4t) for 1 ≤ t ≤ 2.

To convert this line integral to an ordinary integral with respect to the parameter, we need to express the integrand xe^{yz} in terms of the parameter t. We can do this by substituting r(t) into the integrand, giving us

te^{(2t)(-4t)}

= te^{-8t²}

Next, we can use the change of variable formula: ∫Cxe^{yz}ds = ∫[1,2]xe^{yz}||r'(t)||dt

We know that r'(t) = (1, 2, -4), so

||r'(t)|| = √(1² + 2² + (-4)²)

= √(17)

So the new integral becomes ∫[1,2] √(17)te^{-8t²} dt

On calculating ∫[1,2] √(17)te^{-8t²} dt ≈ 8.645×10⁻⁵

Answer:

111,111,111^2

Step-by-step explanation:

so the denominator is just 1+2+3+4+5......+8 added together multiplied by two since it goes down, then +9 as the middle. So 1+2+3....... to 8 is basically just 1+8, 2+7, 3+6, etc. so we have 4 pairs of 9 which is 36. 36*2 is equal to 72, them plus 9 is 81. 999,999,999*999,999,999 can be written as 999,999,999^2. the bottom is 81 so we can square root both top and bottom to get 999,999,999/9 right, and we just square it back so that equals 111,111,111^2 .

The times more six letter combinations can be formed than four letter combinations will be 26² times.

It should be noted that scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper.

Furthermore, the numbers in the millions place after the decimal required to be represented in a simpler format. As a result, representing a few integers in their expanded form is challenging. As a result, we employ scientific notation.

In this case, the number four letter combination that can be formed with the English alphabet is 26 to the fourth power. The number of six letter combination that can be formed is 26 to the sixth power.

The number of times more six letter combinations can be formed than four letter combinations will be:

Step-by-step explanation:

No, the flag pole does not form a 90° angle with the ground.

We can use the Pythagorean theorem to find the length of the flag pole, which states that in a right triangle, the sum of the squares of the two shorter sides equals the square of the longest side (the hypotenuse).

Let x be the length of the flag pole. Then, we have:

x² = (20 - x)² + 28.9²

Expanding and solving for x, we get x = 30.8.

Therefore, the length of the flag pole is 30.8 feet, which is greater than the height of 21 feet. This means that the angle between the flag pole and the ground is not 90°, but rather less than 90°.

We must first calculate the area of a single tile in order to figure how many floor tiles are required to cover a space that is 1080 square meters.

Since the area of a parallelogram is equal to its base times its height, the tile's area is 24 x 10 cm, or 240 [tex]cm^{2}[/tex].

Since one square meter equals 10,000 square centimeters, we divide by 10,000 to convert this area to square meters: 240 [tex]cm^{2}[/tex] / 10,000 = 0.024 c[tex]m^{2}[/tex]

Thus, a single tile has a surface area of 0.024 square meters.

We divide a room's 1080 square meters by a tile's area to determine how many tiles are required to completely cover the space:

1080 [tex]m^{2}[/tex] / 0.024 [tex]m^{2}[/tex]= 45,000

 Therefore ,45,000 floor tiles would be required to cover a space that is 1080 square meters in size.

Answer:

x^3(4+5x^3)cuberoot(x)

Step-by-step explanation:

In order to add the two problems, you need to make sure the radical is the same. Since the cube root of 8x is 2 cuberoot(x) and the cube root of x^10 is x^3 cuberoot(x) this allows the radical to be the same so we can add them.

Now whenever you take out something from within the radical, you multiply it to whatever it is already next to it. So, you would get 4(x^3) cuberoot(x) + 5x^3(x^3) cuberoot(x) From here you get 4(x^3) cuberoot(x) + 5x^6 cuberoot(x).

To finally simplify it, you can put the addition (because the x exponent outside of the cube root isnt the same, you can't add the 4 and 5) so you can get (We can put the x^3 outside of the parenthesis because both numbers have x^3)  x^3(4+5x^3)cuberoot(x)

Answer:

H(x) = (x - 5) * (1 - 0.25) = x - 5 - 0.25x = 0.75x - 5

Answer:

The function H(x) that represents how much you would pay if you use the mall coupon followed by applying the discount from the store would be:

H(x) = (x - 5) * 0.75

Step-by-step explanation:

First, we apply the mall coupon by subtracting $5 from the original cost of the jeans represented by x. This gives us the function f(x) = x - 5.

Next, we apply the store discount of 25% by multiplying the result of f(x) by 0.75. This is because 25% expressed as a decimal is 0.25, and to apply a discount, we multiply by the decimal form of the percentage (1 - decimal form).

So, the final function H(x) represents the cost of the jeans after both the mall coupon and store discount have been applied, and is equal to (x - 5) * 0.75.

The corners of the square touch the circular plot at points W, X, Y, Z. The distance from point W to Y is equal to diameter of the circular plot, that is 14.

A square sand box is in a circular plot of grass so that the corners of the square sandbox  touch the edge of circular the plot. The vertices are W, X, Y, and Z. This situation can be depicted in the attached picture.

The distance from point W to Y is equal to the diameter of the circle.

Answer:

272 units^2

Step-by-step explanation:

1) Find area of whole figure which is a trapezoid.

Area of trapezoid = ((18+34)/2)*16 We are adding the bases, dividing by 2 and multiplying by height. This is the formula to find the area of a trapezoid.

So Area of trapezoid = 416 units^2

2) Find area of non-shaded figure which is a triangle.

Base= 18, Height= 16

Area of triangle = (16*18)/2 We are multiplying the base and height which is the formula to find the area of a triangle.

So Area of triangle = 144 units^2

3) Subtract non-shaded figure from whole figure to get shaded figure.

416-144 = 272 units^2

The equation of the tangent line at any point on the curve is y = f'(x)x + c. For the line to be horizontal, its slope has to be zero, meaning that f'(x) = 0. Therefore, the coordinates of all points on the curve with a horizontal tangent line are those points (x, f(x)) such that f'(x) = 0.

The equation for any line tangent to a curve at a given point (x, f(x)) is given by the equation y = f'(x)x + c, where c is a constant. This equation is derived from the definition of the derivative, which is the instantaneous rate of change of a function at a given point. The slope of this line is equal to the derivative of the curve at the given point, or f'(x). A line is horizontal when its slope is equal to zero, meaning that f'(x) = 0. Therefore, the coordinates of all points on the curve at which the line tangent to the curve at that point is horizontal are all points (x, f(x)) such that f'(x) = 0. This is because a line with a slope of zero is always horizontal, regardless of the value of the constant c. So, in order to find the coordinates of all points on the curve at which the line tangent to the curve at that point is horizontal, we must find all points (x, f(x)) such that f'(x) = 0.

The system of equations for Elliott's situation can be represented as follows:

Let h be the number of hats Elliott makes and s be the number of scarves she makes.

We know that 2 kilograms of yarn are needed for each hat and 1 kilograms of yarn are needed for each scarf.

Therefore, the equation to represent the total amount of yarn used for hats is:

h * 2 = 2h

And the equation to represent the total amount of yarn used for scarves is:

s * 1 = s

Now, we know that Elliott wants to use twice as much yarn for scarves as for hats. This can be represented as:

s = 2h

Finally, we know that Elliott wants to make a total of 202020 items. This can be represented as:

h + s = 202020

Combining all of the equations, we get:

We can use algebra to set up and solve a system of equations to determine the size of a rectangle given the given information.

Step 1: Assign the rectangle's width and length the letters "w" and "l," respectively. We can determine the rectangle's 24 cm perimeter from the problem. The formula P = 2l + 2w = 24 cm can be used to draw up an equation since the perimeter of a rectangle is equal to the total of its four sides.

 Step 2: Using the additional knowledge that the length is 3 cm longer than the width, we can construct a second equation as follows: l = w + 3 cm.

Step 3: We can change the variable "l" in the first equation to read "w + 3," making P = 2(w + 3) + 2w = 24 cm. As a result, we can calculate 2w + 2(w + 3) = 24 cm.

Step 4: Finding the value of w: 24 cm = 2w + 2w + 6.

Step 5: Condensing the formula: 4w = 18 cm.

Sixth step: multiply both sides by 4 to get w = 4.5 cm.

Step 7: Using the second equation, we can get the length now that we know the width: l = w + 3 cm = 4.5 + 3 = 7.5 cm.

  Therefore the answer is option c , width is 4.5 and length is 7.5 .

Step-by-step explanation:

always bring the equation into the form

y = ...

in that case the slope is simply the factor of x.

-7x - 5y = -1

-5y = 7x - 1

y = (-7/5)x + 1/5

so, the slope is -7/5.

a parallel line must have the same slope : -7/5.

a perpendicular slope turns the original y/x slope upside-down and flips the sign :
