which quadrilateral(s) have sides that are referred to as bases and legs

Answer:

Step-by-step explanation:

A correlation coefficient of 0.55 implies a weak positive correlation, because it's close to 0.50. Remember that strong correlations are 1 or -1, positive or negative, and the middle of the interval represents no correlation.

Having said that, 0.55 indicates some correlation, but weak. Therefore, the right answer is C.

The price of the guitar after expansion will be $72. The correct option is H.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that The price of guitars from Universal Guitar Company increased by 80% when the business expanded. If a guitar cost $40 before the expansion.

The price after expansion will be calculated as:-

Price = 40 x 1.8

Price = $72

Answer:

This is because, a relation could be any set of ordered pairs where as a function is a set of ordered pairs where there is only ONE value of y for every value of x.

Another way of explaining it is:

In fact, every function is a relation. However, not every relation is a function. In a function, there cannot be two lists that disagree on only the last element. This would be tantamount to the function having two values for one combination of arguments. By contrast, in a relation, there can be any number of lists that agree on all but the last element.

The statement "All functions are relations but some relations are not functions" highlights the relationship between functions and relations and the distinction between the two concepts.

In mathematics, a relation is a set of ordered pairs that establishes a connection between elements of two sets. It can be thought of as a collection of inputs and outputs.

On the other hand, a function is a specific type of relation in which each input value (x-coordinate) is associated with exactly one output value (y-coordinate).

So, when we say "all functions are relations," we are acknowledging that functions are a subset of relations. This is because functions satisfy the property of assigning a unique output for each input, making them a special kind of relation.

However, the statement also recognizes that there are relations that do not meet the criteria of a function. This occurs when an input value is associated with multiple output values or when an input value has no corresponding output value.

In other words, some relations may have more than one output value for a given input, or they may lack a well-defined output for certain inputs. Such relations are not considered functions.

Therefore, while all functions can be classified as relations, not all relations can be classified as functions due to the specific requirement of having a unique output for each input.

Answer:

25°

Step-by-step explanation:

In \(\triangle BCD\)

BD = CD .....(Given)

\(\implies m\angle CBD = m\angle BCD\)

(By isosceles triangle theorem)

\(m\angle BCD = 60\degree....(given)\)

\(\implies m\angle CBD = 60\degree\)

Now,

\(m\angle CBD + m\angle ABD= 180\degree\)

(Angles in linear pair)

\(\implies 60\degree + m\angle ABD= 180\degree\)

\(\implies m\angle ABD= 180\degree - 60\degree\)

\(\implies m\angle ABD= 120\degree\)

Next, in \(\triangle ABD\)

\(m\angle BAD + m\angle ABD+ m\angle ADB= 180\degree\)

(By interior angle sum postulate of a triangle)

\(\implies 35\degree + 120\degree+ x= 180\degree\)

\(\implies 155\degree+ x= 180\degree\)

\(\implies x= 180\degree-155\degree\)

\(\implies x= 25\degree\)

There are two areas for the rectangle: Case 1: A = 24 ft², Case 2: A = 1285.714 ft².

In this problem we must determine the area of a rectangle, whose perimeter is known. The area (A), in square feet, and perimeter (p), in feet, formulas are introduced below:

p = 72 / (x + 1) + 40 / x

A = (20 / x) · [36 / (x + 1)]

First, we determine the value of x from perimeter:

20 = 72 / (x + 1) + 40 / x

20 = [72 · x + 40 · (x + 1)] / [(x + 1) · x]

20 · [(x + 1) · x] = [72 · x + 40 · (x + 1)]

20 · (x² + x) = 72 · x + 40 · x + 40

20 · x² + 20 · x = 112 · x + 40

20 · x² - 92 · x - 40 = 0

x = 5 or x = 2 / 5

Second, find the area of the rectangle:

Case 1

A = (20 / x) · [36 / (x + 1)]

A = (20 / 5) · [36 / (5 + 1)]

A = 4 · 6

A = 24

Case 2

A = [20 / (2 / 5)] · [36 / (2 / 5 + 1)]

A = 1285.714

Answer:

The lines mean "Absolute Value"

Step-by-step explanation:

"Absolute Value" is always positive. So the problem is actually, 2+3-24/3*2

Only the term "-2-3" is inside the lines so they are the only numbers that have to be or change to positive.

Answer:

Step-by-step explanation:

Those lines are called Absolute Value which can be thought of the distance of the number away from zero.

| -2 - 3 | - 24/3 x 2

1) first we solve the absolute value.

| -5 | -24/3 x 2

2) then we know absolute value is the number from 0 so -5 would be +5 and we can remove the lines because we solved the absolute value.

Answer:

I'd times the first equation by 3 and the second equation by 2. Giving:

6x + 15y = 21

6x + 8y = 12

then I'd subtract the second from the first

6x-6x + 15y-8y = 21-12

7y = 9

y = 7/9

then sub y into one of the equations and solve for x.

Answer:

Step-by-step explanation:

Solving simultanius equation by elimination

2x + 5y = 7 -------------(I)

3x + 4y = 6 ---------------(II)

To eliminate x, multiply equation (I) by (-3) and equation (II) by 2. Then add the two equations. Now, 'x' will be eliminated and we can find the value of 'y'.

(I) *(-3)             -6x  - 15y = -21

(II)*2                 6x +  8y  = 12    {Now add}              

                               - 7y  = -9

                                   y = -9/-7

y = 9/7        

Solution for the equation four fifths times v plus 5 equals three fifths times v minus 6 ,which means (4/5)v+5 = (3/5)v - 6  is v= -55 .

In the question ,

the equation is given as ,(four fifths times v plus 5 equals three fifths times v minus 6) , which means

\(\frac{4}{5} v +5=\frac{3}{5} v-6\)

Combining like terms together and solving we get ,

(4/5)v-(3/5)v = -6-5

Simplifying further we get ,

(1/5)v= -11

v/5 = -11

Multiplying both sides by 5 we get ,

v = -11*5

v= -55

Therefore , the solution for the equation (4/5)v+5 = (3/5)v - 6  is v= -55 .

The equation for the paraboloid z=x² y² in spherical coordinates is ρ⁴ sin²(φ) cos(θ).

To convert from rectangular to spherical coordinates, we use the following equations:

x = ρ sin(φ) cos(θ)

y = ρ sin(φ) sin(θ)

z = ρ cos(φ)

Substituting  z= x² y² into the equation above and simplifying, we get:

ρ cos(φ) = (ρ sin(φ) cos(θ))² (ρ sin(φ) sin(θ))²

ρ³ cos(φ) = ρ⁴ sin²(φ) cos²(θ) sin²(θ)

ρ = ρ⁴ sin²(φ) cos²(θ) sin^2(θ)/cos(φ)

ρ = ρ⁴ sin²(φ) cos(θ)

Finally, we can solve for ρ to get the equation in spherical coordinates as:

\(\rho = \left(\frac{z}{\sin^2(\varphi)}\right)^{\frac{1}{4}}\)

Substituting z=x² y², we get:

\(\rho = \left(\frac{x^2 y^2}{\sin^2\phi}\right)^{\frac{1}{4}}\)

\(\begin{equation}\rho = \left(\frac{\rho^4 \sin^2(\varphi) \cos^2(\theta) \sin^2(\theta)}{\sin^2(\varphi)}\right)^{\frac{1}{4}}\end{equation}\)

\(\begin{equation}\rho = \rho^{\frac{4}{4}} \sin{\phi} \cos{\theta}\end{equation}\)

ρ = ρ sin(φ) cos(θ)

Thus, the equation for the paraboloid z=x² y²  in spherical coordinates is ρ⁴ sin²(φ) cos(θ).
