If the gradient of a line C is 2/3 what is the gradient of the line which is perpendicular to C
Final answer:
The gradient of the line perpendicular to a line with a gradient of 2/3 is -3/2 since perpendicular slopes are negative reciprocals of each other.
Explanation:
If the gradient of a line C is 2/3, we need to find the gradient of the line which is perpendicular to C. In mathematics, particularly in coordinate geometry, the slopes (or gradients) of two perpendicular lines are negative reciprocals of each other. This means that if the slope of the first line is m, the slope of the line perpendicular to it will be -1/m.
Therefore, the gradient of the line perpendicular to line C, which has a gradient of 2/3, will be the negative reciprocal of 2/3.
perpendicular = -1 / (2/3) = -3/2
So, the gradient of the line perpendicular to C is -3/2.
-5 < x - 4 greater than it equal 1
We have expression [tex]-5 < x - 4 \geq 1[/tex] that renders the system of inequalities,
[tex]
\begin{cases}
-5 < x - 4 \\
x - 4 \geq 1
\end{cases}
[/tex]
Which can be simplified to,
[tex]
\begin{cases}
x > -1 \\
x \geq 5
\end{cases}
[/tex]
So what we get is something greater than -1 and at the same time greater or equal to 5, so the solution is,
[tex]x\in(\infty,-1)\cap(\infty, 5]=\boxed{(\infty,5]}[/tex].

What is the Graph function?The graph of a function f is the set of all points inside the aircraft of the shape (x, f(x)). We can also define the graph of f to be the graph of the equation y = f(x). So, the graph of a character is a unique case of the graph of an equation.
How does Graph function?For graphing functions, we need to plot its asymptotes, its x and y-intercepts, holes, and some factors on it by means of building a desk of values. Then simply join the factor by not touching the asymptotes and maintaining a observation of the area and range of the characteristic.

Gina is shopping for a new bicycle. The price of the is $300 and there is an 8% sales tax. Gina wants to know the total price of the bicycle including sales tax.
Which table represents the situation?
Answer:
Sales amount = $ 300.08
Step-by-step explanation:
Sale amount = selling price + sales tax
Here selling price = $300
sales tax = 8 %
sale amount = 300 + 8%
= 300 + 8/100
=( 300 ×100 + 8 )÷100
= (30000 + 8 ) ÷ 100
= 30008 ÷ 100
=$ 300.08
Sales amount = $ 300.08

Answer:
Yes
A parallelogram with opposite sides equal to 6 units and 3 units and each of the pair of opposite angles as equal to [tex]50^{\circ}\,,\,130^{\circ}[/tex]
Step-by-step explanation:
Given: A rectangle has side lengths of 6 units and 3 units
To check: If a quadrilateral can be made that is not identical to the given rectangle using the same four side lengths
Solution:
A parallelogram with opposite sides equal to 6 units and 3 units can be made.
Take each of the pair of opposite angles as equal to [tex]50^{\circ}\,,\,130^{\circ}[/tex]
This parallelogram is not identical to rectangle as each of the angle of the rectangle is equal to [tex]90^{\circ}[/tex] but here each of the pair of opposite angles as equal to [tex]50^{\circ}\,,\,130^{\circ}[/tex].
Yes, one can construct another quadrilateral, such as a parallelogram, using the same side lengths of 3 units and 6 units. While both a rectangle and parallelogram are quadrilaterals, a parallelogram is not identical to a rectangle as not all angles in a parallelogram are right angles.

how do you combine,multiply,divide,and compose functions, and how do you find the domain of the resulting function?
The operations of the function are explained below in the solution.
Let f(x) and g(x) be given functions.
We combine those two functions using following rule
(f±g)(x) = f(x) ± g(x)
The domain of f±g is the intersection of the domain off and the domain
of g.
We multiply those two functions using the following rule:
(f·g)(x) = f(x)-g(x)
The domain of f·g is the set of all real numbers for which f and g and new
function are defined.
We divide those two functions using the following rule:
f/g (x) = f(x) / g(x)
The domain of f/g is set of all real numbers for which ƒ and g and new
function are defined.
We combine these two functions using the following rule:

Final answer:
In mathematics, functions can be combined, multiplied, divided, and composed, and discovering their domain is essential. Combining functions adds their outputs, multiplying them multiplies their outputs, and dividing them divides one output by another. Composing functions applies one to the result of another, with the domain determined by permissible inputs, avoiding division by zero or negative square roots.
Explanation:
When working with functions in mathematics, you can perform several operations, including combining, multiplying, dividing, and composing functions. Finding the domain of the resulting function is crucial as it determines the set of all possible inputs for the function.
Combining Functions
To combine functions (also known as function addition), you simply add the outputs of two functions. For example, if f(x) = 2x and g(x) = x + 3, the combined function is (f + g)(x) = f(x) + g(x) = 2x + (x + 3) = 3x + 3.
Multiplying and Dividing Functions
Multiplying functions involves multiplying the outputs of the functions. If f(x) = 2x and g(x) = x + 3, then[tex](f \cdot g)(x) = f(x) \cdot g(x) = 2x \cdot (x + 3)[/tex]. Dividing functions, on the other hand, involves dividing one output by the other, given that the divisor is not zero.
Composition of Functions
Composing functions refers to applying one function to the result of another function. The composition g o f means applying f first and then g. If h(x) = g(f(x)), you're taking an input x, applying the function f, and then applying g to the result of f(x).
Finding the Domain
The domain of a function is the set of all permissible inputs. To find the domain of a resulting function after performing operations, look for any restrictions such as division by zero or taking the square root of a negative number. For instance, if [tex]f(x) = \sqrt{x}[/tex], the domain is x ≥ 0, as you cannot take the square root of a negative number.

Which of the following explains why Cosine 60 degrees = sine 30 degrees using the unit circle? E2020?
Answer:
A
Step-by-step explanation:
he side opposite a 30° angle is the same as the side adjacent to a 60° angle in a right triangle. On a unit circle, the y (sin) distance of a 30° angle is the same as the x (cos) distance of a 60° angle.
Explanation of Cosine 60 = Sine 30
Cosine :
The trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
Sine :
The trigonometric function that is equal to the ratio of the side opposite a given angle (in a right-angled triangle) to the hypotenuse.
So, these are the reasons :
⇒ The side opposite a 30 degree angle is the same as a side adjacent to 60 degree angle in a right triangle.
⇒ On a unit circle, the y (sin) distance of a 30 degree angle is the same as the x (cos) distance of a 60 degree angle.
