I drew a picture with work; hopefully this is the equation you're using in the lesson.

The equation 7x² - 5x + 7y² + z² = 3 in the cylindrical coordinate system is 7r² - 5r cos θ + z² = 3.

In the cylindrical coordinate system, cylindrical dimensions are ordered triples that describe the location of a point.

The equation is given below.

7x² - 5x + 7y² + z² = 3

The conversion of the cartesian coordinate to the cylindrical coordinate system.

x = r cosθ

y = r sinθ

z = z

Then put these values in the equation. Then we have

[tex]\begin{aligned} 7(r \cos \theta)^2-5(r \cos \theta) + 7(r \sin \theta)^2 + z^2 &=3\\\\7r^2 \cos ^2\theta-5r \cos \theta + 7r^2 \sin ^2\theta + z^2 &=3\\\\7r^2 (\sin ^2\theta + \cos ^2\theta ) - 5r \cos \theta + z^2 &= 3\\\\7r^2 - 5r \cos \theta + z^2 &= 3 \end{aligned}[/tex]

The area bounded by the line y=3x from limits x=0 to x=4 will be 24.

Integration is defined as the adding up all the small units to find the whole unit.

It is given in the question that the line y=3x is making a region in a plane from the limits x= to x=4.

So by integrating the function we will get the area.

[tex]\int\limits^4_0 y=\int\limits^4_0 {3x} \, dx[/tex]

[tex]\int\limits^4_0 y=3 \int\limits^4_0 {x} \, dx[/tex]

[tex]\int\limits^4_0 y=[\dfrac{3x^2}{2}]^4_0[/tex]

[tex]\int\limits^4_0 y= \dfrac{(3\times (4)^2)}{2}[/tex]

[tex]\int\limits^4_0 y= 24[/tex]

hence the region bounded by the line y=3x will have the area of 24 square units.

Answer:

The third comment is the true one: "If I know the measures of angles C and B, I can find the measures of A and D."

This is because you can use the angle B to find angle A by subtracting it from 180, and you can find angle D by adding together C and B and subtracting that from 180.

Answer:

Function 2 shows a greater rate of change, because Edwin spends $9 each month and Adam spends $7 each month.

I found this out because for Adam, you simply subtract the y-coordinates from each other and get 7 each time. Edwin clearly shows that he Spends $9 each month with the negative sign.

Step-by-step explanation:

Answer:

Function 2 shows a greater rate of change, because Henry spends $7 per month and Galvin spends $5 per month.

Step-by-step explanation:

Function 1

Money remaining in Galvin's money box:

[tex]\begin{tabular}{| c | c |}\cline{1-2} Number of Months (x) & Amount Remaining (in \$) (y)\\\cline{1-2} 1 & 80\\\cline{1-2} 2 & 75 \\\cline{1-2} 3 & 70 \\\cline{1-2} 4 & 65 \\\cline{1-2}\end{tabular}[/tex]

We can calculate the rate of change by using this formula:

[tex]\textsf{rate of change}=\dfrac{\textsf{change in y}}{\textsf{change in x}}[/tex]

[tex]\implies \textsf{rate of change}=\dfrac{75-80}{2-1}=\dfrac{-5}{1}=-5[/tex]

Therefore, The rate of change of function 1 is -5 which means that Galvin spends $5 per month.

Function 2

Money remaining in Henry's money box:  

[tex]\sf y = -7x+80[/tex]

This is represented as a linear equation: y = mx + b
(where m is the slope or "rate of change" and b is the y-intercept of "initial value)

Therefore, the rate of change of function 2 is -7 which means that Henry spends $7 per month.

Conclusion

Function 2 shows a greater rate of change, because Henry spends $7 per month and Galvin spends $5 per month.

Answer:

B. x ≤ 5

Step-by-step explanation:

This is an inequality problem. It can be solved by examining the arrow and the point it closes on. If the arrow is going left, then all values of x are going to be less than the point it closes on. If the arrow is going right, then all values of x are going to be greater than the point it closes on.
If the circle on the point the arrow is closed/shaded in, then that value will be included in the values of x, giving the inequality either a ≤ or ≥ sign depending on which way the arrow is pointing. If the circle on the point the arrow is open, then that value will not be included in the values of x. The sign will be either < or >.

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

For this problem, the arrow is going to the left of 5, which means all values of x are going to be less than 5. Because the circle is closed, that means that number 5 is included, or x can be equal to 5. If the circle was open, it wouldn't be included. So, the inequality is x ≤ 5.

Step-by-step explanation:

6*3.14 = 18.84

The solution is 62.84 m

The perimeter of the figure is P = 62.84 m

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the perimeter of the figure be represented as P

Now , the figure has a semi circle , a square and a triangle

The side of the square = 12m

So , the number of sides of square in the perimeter of the figure = 2 sides

So , perimeter of 2 sides = 2 x 12 = 24 m

Now , the 2 sides of the hypotenuse of the right triangle is also part of the figure , so

perimeter of 2 sides of the triangle = 2 x 10 = 20 m

Now , the total perimeter of figure = perimeter of the semi circle + 24 + 20

Perimeter of semi circle = 2πr / 2

The radius of the circle = 6 m

Substituting the value of r in the equation , we get

Perimeter of the semi circle = ( 2 x 3.14 x 6 ) / 2

Perimeter of the semi circle = 18.84 m

So , the perimeter of the figure P = 18.84 m + 24 m + 20 m

The perimeter of the figure P = 62.84 m

Therefore , the value of P is 62.84 m

Hence , The perimeter of the figure is P = 62.84 m
