Différenciation implicit function containing product and quotient. d/dx (2y/5x)
Answer:
To differentiate the given expression, we will need to use both the product rule and the quotient rule.
Let's first rewrite the expression using the reciprocal identity for x:
2y/5x = 2y * (5x)^(-1)
Now we can use the product rule and the quotient rule to find the derivative with respect to x:
d/dx [2y * (5x)^(-1)] = 2y * d/dx[(5x)^(-1)] + (5x)^(-1) * d/dx[2y]
Using the chain rule, we can find the derivative of (5x)^(-1) with respect to x:
d/dx[(5x)^(-1)] = -1/(5x)^2 * 5 * (dx/dx)
d/dx[(5x)^(-1)] = -1/(5x)^2
Using the chain rule again, we can find the derivative of 2y with respect to x:
d/dx[2y] = 2 * (dy/dx)
Substituting these expressions back into the original equation, we get:
d/dx [2y/5x] = 2y * (-1/(5x)^2) + (5x)^(-1) * 2 * (dy/dx)
Simplifying this expression, we get:
d/dx [2y/5x] = -2y/(5x)^2 + 2/(5x) * (dy/dx)
Therefore, the derivative of 2y/5x with respect to x is -2y/(5x)^2 + 2/(5x) * (dy/dx).
Angel made a table runner that has an area of 80 square inches. The length and width of the table runner are whole numbers. The length is 5 times greater than the width. What are the dimensions of the table runner?
the dimensions of the table runner are [tex]20[/tex] inches in length and [tex]4[/tex] inches in width.
What are the dimensions?Let's denote the width of the table runner as "w" inches. Since the length is 5 times greater than the width, the length would be 5w inches.
The area of a rectangle is calculated by multiplying its length by its width. Given that the area of the table runner is 80 square inches, we can set up the following equation:
Length × Width = Area
[tex](5w) \imes w = 80[/tex]
Simplifying further:
[tex]5w^2 = 80[/tex]
Dividing both sides by 5:
[tex]w^2 = 16[/tex]
Taking the square root of both sides:
w = ±4
Since the width cannot be negative in this context, we discard the negative value. Therefore, the width (w) of the table runner is [tex]4[/tex] inches.
Substituting this value back into the equation for length:
Length [tex]= 5w = 5 \times 4 = 20[/tex] inches
So, the dimensions of the table runner are [tex]20[/tex] inches in length and 4 inches in width.

Describe at least two differences between constructing parallel lines and constructing perpendicular lines.
By using the compass to measure a distance from the original line, and then transferring that distance to another point on the line, a parallel line can be drawn.
What is the parallel lines?
Parallel lines are two lines in a plane that never intersect.
1. Orientation of Lines:
Parallel lines are lines that never intersect and remain equidistant from each other at all points.
When constructing parallel lines, the lines are drawn in the same direction and maintain the same distance between them throughout their entire length. They do not meet or cross each other.
On the other hand, perpendicular lines are lines that intersect at a right angle (90 degrees). When constructing perpendicular lines, the lines are drawn so that they intersect at a right angle, forming four right angles at the point of intersection.
2. Tools/Methods Used:
Constructing parallel lines and constructing perpendicular lines may require different tools or methods.
To construct parallel lines, one common method is to use a straightedge and a compass. A straightedge is used to draw a straight line, and a compass is used to measure and transfer distances to create additional parallel lines.

Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options.
The radius of the circle is 3 units.
The center of the circle lies on the x-axis.
The center of the circle lies on the y-axis.
The standard form of the equation is (x – 1)² + y² = 3.
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
The x-axis is where the circle centre is located. Three units make up the circle's radius. This circle's radius coincides with the radius of the circle whose equation is x² + y² = 9.
What is the circle's equation when its centre is on the x-axis?The y coordinate of a circle's centre will be 0 if the circle's centre is on the x-axis. The circle's equation will therefore have the generic form x2 + y2 + 2gx + c = 0, where g and c are constants.
Circle's standard equation is written as:
x²+y²+2gx+2fy+C=0
Centre is (-g, -f)
radius = √g²+f²-C
Given a circle whose equation is : x²+y²-2x-8=0
Get the centre of the circle
2gx = -2x
2g = -2
g = -1
Similarly, 2fy = 0
f = 0
Centre = (-(-1), 0) = (1, 0)
This demonstrates circle's centre is on the x-axis.
r = radius = √g²+f²-C
radius = √1²+0²-(-8)
radius =√9 = 3 units
The circle has a radius of three units.
For the circle x²+y²=9, radius is expressed as:

Answer:
To check whether 40, -40, 16, or -16 is the solution of the equation 28 = d - 12, we can substitute each value into the equation and see if it results in a true statement.
When we substitute 40 into the equation, we get:
28 = 40 - 12
Simplifying, we get:
28 = 28
This is a true statement, so 40 is a solution of the equation.
When we substitute -40 into the equation, we get:
28 = -40 - 12
Simplifying, we get:
28 = -52
This is not a true statement, so -40 is not a solution of the equation.
When we substitute 16 into the equation, we get:
28 = 16 - 12
Simplifying, we get:
28 = 4
This is not a true statement, so 16 is not a solution of the equation.
When we substitute -16 into the equation, we get:
28 = -16 - 12
Simplifying, we get:
28 = -28
This is not a true statement, so -16 is not a solution of the equation.
Therefore, the only solution of the equation 28 = d - 12 is d = 40.

It is also used in physics to calculate the amount of surface area of an object that is exposed to air or water, and in architecture and engineering to determine the amount of material needed to construct a building or structure.
Here,
To find the perimeter of a rectangle, we need to know its length and width. We are given that the width of the rectangle is 9 centimeters, and the area of the rectangle is 108 square centimeters.
We can use the formula for the area of a rectangle:
Area of rectangle = length x width
Plugging in the values we have:
108cm² = length x 9cm
Solving for the length, we can divide both sides by 9cm:
length = 108cm² / 9cm
length = 12cm
So, the length of the rectangle is 12 centimeters.
To find the perimeter of the rectangle, we can use the formula:
Perimeter of rectangle = 2 x (length + width)
Plugging in the values we have:
Perimeter of rectangle = 2 x (12cm + 9cm)
Perimeter of rectangle = 2 x 21cm

The function g(x) is a cubic function, which is a transformation of the cube root parent function, f(x) = 3√x. The equation for g(x) is g(x) = 3x3, where a = 3, b = 0, c = 0, and d = 0.
What is function?Function is a set of instructions or commands that can be used to perform a specific task. It is a reusable code that can be used over and over again to perform a similar task. Functions are used to structure programs, making them easier to read, understand, and debug. Functions are also used to divide a large program into smaller, more manageable parts.
The function g(x) is a cubic function, which is a transformation of the cube root parent function, f(x) = 3√x. A cubic function is a polynomial of degree 3, where the highest exponent of the variable is 3. The general equation for a cubic function is y = ax3 + bx2 + cx + d, where a, b, c, and d are constants. This equation can be rearranged to express the function in terms of x, as follows:
g(x) = ax3 + bx2 + cx + d
By plugging in the values for f(x), we can determine the values of a, b, c, and d. We can start by setting f(x) equal to g(x).
3√x = ax3 + bx2 + cx + d
By taking the cube root of both sides, we can determine the value of a:
a = 3
Next, we can substitute this value into the equation for g(x):
g(x) = 3x3 + bx2 + cx + d
From this, we can see that b = 0, c = 0, and d = 0. Therefore, the function g(x) is a cubic function with equation g(x) = 3x3.

A conic has vertices at (0,8) and (0,-8) and foci at F(0, √48) and F(0,-√48). (a) Write the standard form of the equation of this conic.
The standard form of the equation of the conic is x² + y² - 16x - 16y - 192 = 0.
What is conic?It is a type of curve with a curved line in the middle and two straight lines on the sides. Conic sections include circles, ellipses, parabolas, and hyperbolas.
The standard form of the equation of a conic is
Ax² + Bxy + Cy² + Dx + Ey + F = 0, where A, B, C, D, E, and F are constants.
In this case, the equation of the conic is x² + y² - 16x - 16y - 192 = 0.
To derive this equation, we'll use the distance formula to calculate the distance between the vertices and the foci. The distance between the vertices and the foci is given by
d = √((x_1 - x_2)² + (y_1 - y_2)²)
where (x_1, y_1) is the coordinates of the first vertex and (x_2, y_2) is the coordinates of the first foci.
For the first vertex, (x_1, y_1) = (0, 8). For the first foci, (x_2, y_2) = (0, √48). Thus, the distance between the two points is
d = √((0 - 0)² + (8 - √48)² )
= √(0 + (-8 - √48)² )
= √(-16 - 2√48 + 48)
= √(32 -2√48)
= 2√(16 - √48)
= 2√(16 - 6.9)
= 2√(9)
= 2(3)
= 6
So, the distance between the vertices and the foci is 6.
The equation of the conic can then be written as x² + y² - 16x - 16y - (-8)² = 0, which simplifies to x² + y² - 16x - 16y - 192 = 0.
Thus, the standard form of the equation of the conic is x² + y² - 16x - 16y - 192 = 0.

By answering the presented question, we may conclude that As a result, adding the isosceles triangle categorization is superfluous and redundant in this circumstance.
What is triangle?A triangle is a polygon since it has three sides and three vertices. It is a basic geometric shape. Triangle ABC refers to a triangle with the vertices A, B, and C. In Euclidean geometry, a single plane and triangle are obtained when the three points are not collinear. If a triangle has three sides and three corners, it is a polygon. The triangle's corners are the spots where the three sides meet. The sum of three triangle angles equals 180 degrees.
An isosceles triangle has two sides of equal length, but a right triangle has one angle that measures 90 degrees. As a result, an isosceles right triangle is one with two equal-length sides and one 90-degree angle.
The Pythagorean theorem states that in any right triangle, the two legs (the sides next to the right angle) are always of equal length. Hence, if we know that a triangle has one 90-degree angle and two equal-length sides, we already know that it is a right triangle and that the two legs are equal. As a result, adding the isosceles triangle categorization is superfluous and redundant in this circumstance.
