Write the eq in cylindrical coordinates 7x^2-5x 7y^2 z^2=3
The equation 7x² - 5x + 7y² + z² = 3 in the cylindrical coordinate system is 7r² - 5r cos θ + z² = 3.
What is the cylindrical coordinate?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]

A roll of tape has a circumference of 19 centimeters. The circumference decreases 4 centimeters after you use some of the tape. What is the diameter of the roll after you use the tape?
QUICK PLS
Answer:
4.77 cm correct to the nearest hundredth.
Step-by-step explanation:
The new circumference = 19 - 4 = 15 cm.
Circumference C = π * diameter
So the diameter = C/π = 15/π = 4.7746 cm

Galvin and Henry spend a certain amount of money from their money box each month to buy plants. The table (function 1) shows the relationship between the amount of money (y) remaining in Galvin’s money box and the number of months (x): Number of Months (x) Amount Remaining (in $) (y) 1 80 2 75 3 70 4 65 The equation (function 2) shows the relationship between the amount of money, y, remaining in Henry’s money box and the number of months, x: Function 2 y = −7x + 80 Which statement explains which function shows a greater rate of change? Function 2 shows a greater rate of change, because Henry spends $7 each month and Galvin spends $5 each month. Function 2 shows a greater rate of change, because Henry spends $80 each month and Galvin spends $15 each month. Function 1 shows a greater rate of change, because Galvin spends $15 each month and Henry spends $73 each month. Function 1 shows a greater rate of change, because Galvin spends $5 each month and Henry spends −$7 each month.
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.

The air temperature of a town was 22 degrees. It decreased by 12.5 percent. What was the new
temperature?
Answer:
19.25 degrees
Step-by-step explanation:
original temperature = 22 degrees
decreased percentage = 12.5 percents
the new temperature = 22 - (22×[12.5÷100])
=22 - (137.5÷50)
=22 - 2.75

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.

Several students made comments about this image.
A triangle has angles B, C, D. The exterior angle to angle B is A.
Which comment is true?
“If I know the measures of A and B, I can subtract those measures from 180 to find the measures of the other two angles.”
“If I know the measure of C, I can find the measure of angle A because they are the same.”
“If I know the measures of angles C and B, I can find the measures of A and D.”
“If I know the measure of angle A, I can find the measure of angle D by subtracting from 180
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.

Find the outer perimeter of this figure.
Round your answer to the nearest
hundredth. Use 3.14 to approximate pi.
Answer:
62.84 m
Step-by-step explanation:
6*3.14 = 18.84
12*2 = 24
10*2 = 20
total: 62.84
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
