Parameterize [tex]C[/tex] by

[tex]\vec r(t)=(1-t)(0,0,0)+t(1,3,6)=(t,3t,6t)[/tex]

with [tex]0\le t\le1[/tex]. Then the line integral is

[tex]\displaystyle\int_Cxyz\,\mathrm dS=\int_0^1x(t)y(t)z(t)\left\|\frac{\mathrm d\vec r}{\mathrm dt}\right\|\,\mathrm dt[/tex]

[tex]=\displaystyle18\sqrt{91}\int_0^1t^3\,\mathrm dt=\boxed{\frac{9\sqrt{91}}2}[/tex]

The line integral over the path C from (0,0,0) to (1,3,6) can be converted into an ordinary integral by parameterizing the line segment and then substituting in the integral. The result of the integral amounts to 5.

The given integral involves a line segment from (0,0,0) to (1,3,6). Our task is to convert this line integral to an ordinary integral.

The path C from (0, 0, 0) to (1, 3, 6) can be parameterized as r(t) = ti + 3tj + 6tk for 0 ≤ t ≤ 1. So, the dr = dt(i + 3j + 6k).

Substituting for ds in the integral, we get: ∫ r(t)dt from 0 to 1, which can be reduced to three separate integrals with respect to x, y, and z respectively: ∫xdx from 0 to 1, ∫3ydy from 0 to 1, and ∫6zdz from 0 to 1. Now these can be easily integrated.

So, the solution will be:
∫xdx from 0 to 1 = [x^2/2] from 0 to 1 = 1/2,
∫3ydy from 0 to 1 = [3y^2/2] from 0 to 1 = 3/2,
∫6zdz from 0 to 1 = [6z^2/2] from 0 to 1 = 3.

Adding these up gives the result of the original line integral, which is 5.

Answer:

  The area of the triangle is 0.5 square units more than the area of the parallelogram.

Step-by-step explanation:

The vertical sides of the parallelogram are 3 units long and separated by 2 units. Hence the area of that figure is 3×2 = 6 square units.

The leg lengths of the right triangle are each

  √(2^2 + 3^2) = √13

so the area of the triangle is ...

  A = (1/2)(√13)^2 = 13/2 = 6.5

The triangle has area 0.5 square units more than the parallelogram.

The answers to the questions are: -20 for Q1, 70/9 for Q2, 36 for Q3, and -1 for Q4.

Q1: If r = 9, b = 5, and g = -6, what does (r + b - g)(b + g) equal?

First, calculate the expression inside the parentheses:

r + b - g = 9 + 5 - (-6) = 9 + 5 + 6 = 20

b + g = 5 + (-6) = 5 - 6 = -1

Now multiply these results together:

(r + b - g)(b + g) = 20 × (-1) = -20

The answer is -20.

Q2: If 9(x - 9) = -11, then x =?

First, simplify the equation:

9x - 81 = -11

9x = 70

Now, solve for x:

x =  rac{70}{9}

The answer is 70/9.

Q3: If (1/2)x + (2/3)y = 6, what is 3x + 4y?

Multiply the original equation by 6 to eliminate the fractions:

6((1/2)x) + 6((2/3)y) = 6 × 6

3x + 4y = 36

The answer is 36.

Q4: Evaluate f(x) = 4x + 3x² - 5 when x = -2

Substitute -2 for x and calculate f(x):

f(-2) = 4(-2) + 3(-2)² - 5

f(-2) = -8 + 3(4) - 5

f(-2) = -8 + 12 - 5

f(-2) = -1

The answer is -1.

Answer: First Option (2,-7)

Step-by-step explanation:

We have a system of equations formed by the following equations:

[tex]x + y = -5\\\\4x + y = 1[/tex]

To answer this question we must solve the system of equations. There are several ways to solve it. The easiest way to solve it for this case is to multiply the second equation by -1 and then add it to the first equation.

[tex]\ \ \ x + y = -5\\-4x - y = -1[/tex]

----------------------

[tex]-3x + 0 = -6\\\\x = 2[/tex]

Now substitute x = 2 in any of the system equations and solve for y.

[tex]2 + y = -5\\\\y = -7[/tex]

Therefore the solution of the system is the point: (2, -7)

Answer:

The transformation was not done is Shifted left 3 units

Step-by-step explanation:

* Lets talk about the transformation

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) reflected across the y-axis, then the new

 function g(x) = f(-x)

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

- A vertical stretching is the stretching of the graph away from

 the x-axis

- A vertical compression is the squeezing of the graph toward

 the x-axis.

- if k > 1, the graph of y = k•f(x) is the graph of f(x) vertically

  stretched by multiplying each of its y-coordinates by k.

- if 0 < k < 1 (a fraction), the graph is f(x) vertically compressed

 by multiplying each of its y-coordinates by k.

- if k should be negative, the vertical stretch or compress is

 followed by a reflection across the x-axis.  

* now lets solve the problem

∵ f(x) = x

∵ g(x) = -1/2 (x - 3) + 7

# -1/2 means the graph is vertically compressed by a factor of 2

  and reflected over the x-axis

# x - 3 means the graph shifted to the right 3 units

# + 7 means the graph shifted up 7 units

* The transformation was not done is Shifted left 3 units

Answer:

8.5

Step-by-step explanation:

Twice the difference of a number and 6 equals 5 is written algebraically as 2(x-6)=5, where x is the number. Solving for x:

2(x-6)=5

(x-6)=5/2

x=6+5/2

x=17/2

So the number is 17/2, or, expressed as a decimal number, 8.5

We solve the equation 'Twice the difference of a number and 6 equals 5' by identifying variable 'x' as the unknown number, rearranging the equation, and then performing a series of number operations (multiplication, addition, and division) to find x = 8.5.

In the given problem, you are asked to solve for a number in the equation 'Twice the difference of a number and 6 equals 5'. We denote the unknown number we’re looking for as ‘x’. Thus, the equation becomes 2(x - 6) = 5.

By solving this equation step-by-step, we first distribute the 2 to both terms in the parentheses. This key step gives us 2x - 12 = 5.

Next, we add 12 to both sides to isolate 2x on the left side, which gives 2x = 17.

Finally, we divide both sides by 2 to solve for x, giving us x = 17 / 2 or 8.5.

In conclusion, the unknown number x that satisfies the condition 'Twice the difference of a number and 6 equals 5' is 8.5.

Answer:

Step-by-step explanation:

f(x) = x becomes g(x) = (1/5)x through vertical compression by a factor of 5.

We have to vertically compress by a factor of 5 the liner parent function s(X)=x to get the function g(x)=1/5x.

A function is relationship between two variables in such a way that all the values of x corresponds to values of y.

The given function is f(X)=x and we need to form the function g(x)=1/5x from the function f(x)=x. Because we need to change the value of the function means we are changing y so we need to vertically walk in the graph. If we walk horizontally we might change the value of x.

Hence to get the function g(x)=1/5x we need to vertically compress by a factor 5 the function f(x)=x.

b.The bank will seize the car and likely sell it to pay off Jason’s loan.

Option B is the right option.

A collateral is something that a person keeps as a security against some loan. If he fails to re-pay the loan, the collateral is seized by the lender.

Here, it is given that Jason used his car as collateral to borrow money from his bank. Now unable to make his monthly payments for the loan, defaulting on the loan.

In this case, the bank will seize his car or collateral.

Answer:

12.3

Step-by-step explanation:

In order to find the solution.

1. You need to memorize the formula for the area of a sector, which is

   (central angle/360) * pi (r)^2

2. You then plug in the variables carefully.

    * You were given the diameter. Transform the diameter into radius by diving the diameter by two

     (200/360) * pi (2.65)^2

3. Simplify and round to nearest tenth

    12.3

The area of a sector with a central angle of 200 degrees and a diameter of 5.3 cm can be found by first finding the area of the full circle and then scaling it by the ratio of the central angle to the full circle angle (360 degrees). The final answer is approximately 12.2 cm².

First, let's clear up some definitions. A sector is a part of a circle, defined by two radii and their enclosed arc. The central angle here is the angle at the centre of the circle formed by the two radii.

Start by calculating the radius of the circle. Given the diameter is 5.3 cm, the radius would be half of that, which is 2.65 cm.

The area ('A') of a full circle is calculated by the formula A = πr² where 'r' is the radius. Substituting the values to find the area of the full circle, we get A = π * (2.65 cm)² = 22.02 cm².

Since we are not interested in the area of the full circle but rather a sector of the circle, we need to scale this area down by the ratio of the central angle of the sector to the full angle of the circle (360 degrees). So, the area of the sector is (200/360) * 22.02 cm² = 12.2 cm².

So, the area of the circle sector is approximately 12.2 cm² when rounded to the nearest tenth.

  range of f(x) = [-4, -2) ∪ [2, 8)

  a+b+c+d = -4

Step-by-step explanation:

The graph is attached. The range is the vertical extent of the function. It is defined at f(0) = -4 and f(2) = 2.

The limits f(2-) and f(4-) are -2 and 8, respectively, so the graph has open circles there. These are the ends of the two half-open intervals that make up the range of the function.

The portion of the graph in the domain [4, 7) is included in the range [2, 8), so no special treatment is needed for that piece of the function.
