The expression cos(a-b) is equivalent to cos(a)cos(b) + sin(a)sin(b), while the expression cos(a)cos(b) - sin(a)sin(b) is equivalent to cos(a+b).

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It focuses on the study of the properties of trigonometric functions such as sine, cosine, and tangent, which are used to calculate the angles and sides of triangles.

in the given question,

The expression cos(a-b) is equivalent to cos(a)cos(b) + sin(a)sin(b), while the expression cos(a)cos(b) - sin(a)sin(b) is equivalent to cos(a+b).

Therefore, we can rewrite the expression cos(a-b) as cos(a)cos(b) + sin(a)sin(b) and then compare it to the expression cos(a)cos(b) - sin(a)sin(b) by changing the sign of the second term in the first expression:

By comparing these two expressions, we can see that they are very similar, except that the sign of the second term is different. Specifically, we have:

So, we can say that the values of cos(a-b) and cos(a)cos(b) - sin(a)sin(b) are related by the sign of the sin(a)sin(b) term. If the sign is positive in the first expression, then it is negative in the second expression and vice versa.

The reference angle for A = -300° is given by R = 60°

Every angle is measured from the positive part of the x-axis to its terminal line (the line that determines the end of the angle) traveling counterclockwise. For angles in the first quadrant, i.e., angles less than or equal to 90 degrees, the reference angle is equal to the original angle.

The reference angle is always positive

0° to 90°: reference angle = angle

90° to 180°: reference angle = 180° - angle

180° to 270°: reference angle = angle - 180°

270° to 360°: reference angle = 360° - angle

Given data ,

Let the reference angle be represented as R

Now , let the given angle be A

A = -300°

And , for 270° to 360°: reference angle = 360° - angle

when the angle is negative and less than -270°

The reference angle is given by adding 360° to it and the angle lies in the first quadrant

So , the reference angle R = A + 360°

R = -300 + 360

R = 60°

Hence , the reference angle is 60°

Step-by-step explanation:

Zeros, vertex, and end behavior can all be used to determine the height that the golf ball travels from its initial location to the point where the golf ball starts falling towards the ground.

Graph is a data structure that consists of a set of nodes and edges that connect those nodes. Nodes are used to represent entities, such as people, places, or objects, and edges are used to represent the connections between those entities. Graphs are used to represent relationships between data, such as in networks, social media, and biological systems. Graphs can also be used to represent mathematical equations, as in function graphs.

Zeros, or x-intercepts, are the points where the graph of the quadratic function crosses the x-axis. The vertex is the highest point of the graph and can be used to determine the peak of the golf ball's trajectory. Finally, the end behavior of the graph can be used to determine how the graph will change as x increases or decreases without bound. This can be used to determine the point at which the golf ball begins to fall towards the ground.

binary operation has at most one identity element.

A binary operation is a mathematical operation that takes two elements from a set and combines them to produce a third element in the same set. In other words, it is an operation that involves two operands, which can be numbers, variables, or other mathematical objects.

Let's suppose that a binary operation "⋆" has two identity elements "e" and "f", where "e" and "f" are distinct. This means that for any element "a" in the set on which the binary operation is defined, we have:

a ⋆ e = a and f ⋆ a = a (since "e" and "f" are identity elements)

Now, let's consider what happens when we apply the binary operation "⋆" to "e" and "f":

e ⋆ f = f (since "e" is an identity element)

e ⋆ f = e (since "f" is an identity element)

This means that "f = e", which contradicts our assumption that "e" and "f" are distinct. Therefore, it is not possible for a binary operation to have two distinct identity elements.

Hence, we can conclude that a binary operation has at most one identity element.

Answer:

To solve the equation -7(1-4m)=13(2m-3), we can start by simplifying each side of the equation:

-7(1-4m) = 13(2m-3)

-7 + 28m = 26m - 39 (distributing the -7 and 13)

Next, we can simplify further by combining like terms:

28m - 26m = -39 + 7

2m = -32

Finally, we can solve for m by dividing both sides of the equation by 2:

m = -16

Therefore, the solution to the equation -7(1-4m)=13(2m-3) is m = -16.

Answer:

[tex] \sf \: m = - 16[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of m.

The equation is,

→ -7(1 - 4m) = 13(2m - 3)

Then the value of m will be,

→ -7(1 - 4m) = 13(2m - 3)

→ -7(1) + 7(4m) = 13(2m) - 13(3)

→ -7 + 28m = 26m - 39

→ 28m - 26m = 7 - 39

→ 2m = -32

→ m = -32 ÷ 2

→ [ m = -16 ]

Hence, the value of m is -16.

The function will be g(x ) = x² + 2

A function is a special form of relation where each input has exactly one output. In other words, for each input value, the function returns exactly one value. A relation rather than a function is depicted in the above graph since one is mapped to two different values.

But, if one were instead mapped to a single value, the relationship described above would change into a function. Furthermore, output values could match input values exactly.

The function machine receives the x-values as input. After finishing its operations, the function machine produces the y-values. Any function may be the one within.

g(x) = x2 + 2

Now we need to but this in vertex form.

If you graph this equation, you will see that the vertex is (0,2). Plug this in to (h,k) in the equation. The value of a is just 1 because you didn't multiply by anything during the transformation.

So you get g(x) = (x-0)2 + 2 = x2 + 2

This ends up just being the same as the standard form of the equation

A pattern in mathematics is a series of recurring figures, shapes, or numbers. Any kind of event or thing can be connected to a pattern. A pattern has a rule that identifies the items that are part of the pattern and those that are not. There are many distinct kinds of patterns, including word patterns, logic patterns, image patterns, and number patterns. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series. The number of patterns can be limitless or finite.

We are asked to find the missing digits to complete the pattern.

Using Pythagοras theοrem, The length οf the bridge needed tο cοnnect Main Street and Secοnd Street is apprοximately 4.53 miles.

A basic geοmetry theοrem that deals with the sides οf a right triangle is knοwn as the Pythagοrean theοrem. Accοrding tο the theοrem, the square οf the length οf a right triangle's hypοtenuse—its lοngest side—is equal tο the sum οf the squares οf the lengths οf the triangle's οther twο sides, which are referred tο as its legs.

The fοllοwing is hοw the theοrem is written in mathematical nοtatiοn:

[tex]c^2 = a^2 + b^2[/tex]

Where a and b are the lengths οf the οther twο sides (legs) οf the right triangle and c is the length οf the hypοtenuse. The Pythagοrean equatiοn is a cοmmοn fοrm fοr expressing this relatiοnship.

Pythagοras, an ancient Greek mathematician, is credited with discοvering the Pythagοrean theοrem, which bears his name. It has several uses in physics, engineering, mathematics, and οther disciplines.

Tο determine the length οf the bridge needed tο cοnnect Main Street and Secοnd Street, we need tο find the distance between the twο streets.

We can dο this by using the Pythagοrean theοrem, which states that in a right triangle, the square οf the length οf the hypοtenuse (the lοngest side) is equal tο the sum οf the squares οf the lengths οf the οther twο sides.

In this case, we can think οf the bridge as the hypοtenuse οf a right triangle, with Main Street and Secοnd Street fοrming the οther twο sides. We can then use the Pythagοrean theοrem tο find the length οf the bridge as fοllοws:

Length οf the bridge = square rοot of ([tex]3.4^2 + 3^2[/tex])

= square roοt of (11.56 + 9)

= square roοt of 20.56
