The exact value of the tan(75°), found using trigonometric identities for the tangent of the sum of two angles, indicates that the exact value of tan(75°) is (1+√3/3)/(1 - √3/3))

Trigonometric identities are equalities of expressions that includes trigonometric functions which are valid for all values of the argument, or the domain of the function.

The exact value of tan(75°) can be found from the formula for the tangent of the sum of two angles as follows;

tan(A + B) = (tan(A) + tan(B))/(1 - tan(A)•tan(B))

tan(75°) = tan(45° + 30°)

tan(45° + 30°) = (tan(45°) + tan(30°))/(1 - tan(45°)•tan(30°))

tan(30°) = √3/3

tan(45°) = 1

tan(45° + 30°) = (1 + √3/3)/(1 - √3/3)

tan(75°) = (1 + √3/3)/(1 - √3/3)

The correct option is therefore option B

[tex]tan(75 ^{ \circ } ) = \dfrac{1 + \frac{ \sqrt{3} }{3} }{1 - \frac{ \sqrt{3} }{3} } [/tex]

3. Vertical Angles Theorem (1st Occurrence)

4. Transitive Property of Congruence

5. Converse of the Alternate Interior Angles Theorem

Step-by-step explanation:

Vertical Angles Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Transitive Property of Congruence

If one pair of angles is congruent to a third angle, then the first angle is congruent to the third angle.

Converse of the Alternate Interior Angles Theorem

If two lines are intersected by a transversal so that the alternate interior angles are congruent, then the lines are parallel.

From inspection of the given diagram, we can see that angles 2 and 3 are vertical angles, similarly angles 6 and 7 are vertical angles.  Therefore, the Vertical Angles Theorem applies.

According to the Transitive Property of Congruence,  if ∠2 ≅ ∠7 and ∠2 ≅ ∠3 and ∠6 ≅ ∠7 then ∠3 ≅ ∠6.

The two lines a and b are intersected by transversal [tex]\ell[/tex] so that the alternative interior angles 3 and 6 area congruent, then the lines a and b are parallel.  This is the Converse of the Alternate Interior Angles Theorem.

Answer: it's still $100 because the beginning of the year hasn't started yet so you need to wait for the year to end so the 1 percent can be added

Step-by-step explanation:

The value of a is 71°, and the value of b is 109°.

A parallel lines is defined as those type of line that are equidistant to each other which are on the same plane and they doesn't meet each other till infinity.

When two parallel lines are being intersected by another line called the transverse line, the following relationship is bound to occur such as;

From model 4, the pair of alternate exterior angles are equal in measure. That is 71° = angle opposite b°.

That is 180 - 71 = 109°

Answer:

16R = T or T = 16R

Step-by-step explanation:

R represents the unknown amount of rows and we know there are 16 boxes in each row.

This means to find the total number of boxes on display, you will have to times the number of rows by 16 as the clerk puts 16 boxes of cereal in each row

e.g, if there are 3 rows, then to find the total amount of cereal boxes, you would do 3 × 16 = 48

Since it's an expression, you need something to represent the total number so that can be represented by any letter ( I chose T ) — in most cases you can probably represent the total as x

Hence the expression should be 16R = T or T = 16R

Step-by-step explanation:

A y-intercept is a point where a function (i.e a line) intercepts the y-axis.

Every point on the y-axis has a x value of 0.

The ordered pair will look like this (0,y)

In answer a, you have an x value of 0 with a corresponding y value of 3.

This point is (0,3).

You could also graph the points and look for where the function crosses the y-axis.

a) The value of g(2) = -1/4 and the value of g(-2) = π/2 - 3/2

b) The value of g'(x) = 2 The value of g''(x) =1

c) g has neither a relative maximum nor a relative minimum at x= 1

d) the graph of g has a point of inflection at each of x=-2 ,  x=0 and x = 1 because g''(x) = f'(x) changes at each of these values.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).

There are several types of functions in maths. Some important types are:

Injective function or One-to-one function: When there is mapping for a range for each domain between two sets.

Surjective functions or Onto function: When there is more than one element mapped from domain to range.

Polynomial function: The function which consists of polynomials.

The number line which describes the the measure of third side of the triangle must be greater than 10 cm is the second figure.

Number line is a straight horizontal line on which numbers are written in a certain intervals.

We can use number line for basic mathematical operations like addition, subtraction, division and multiplication.

Here the situation described is that measure of the third side of the triangle must be greater than 10 cm.

The inequality sign is '> 10'.

Since the inequality sign does not contain the equal to (≥) sign, the point 10 does not belong to this set.

So we will mark an open circle at the point 10 and draw a line afterwards.

Hence the second number line describes the situation that the third side of the triangle must be greater than 10 cm.

The upper bounds on the probability that Adam sent at least five emails during the time interval is [0, 1].

in math upper bound refers a number that is greater than or equal to any number in a set

Here we have given that, Adam logs in to an email server at time zero. He then spends his time exclusively on writing emails. His friend Brianna also logs in to the server at time 1 (which means 1 hour later) and starts typing emails independently of Adam.

And we need to find the upper bounds on the probability that Adam sent at least five emails during the time interval.

While we looking into the given question, we have identified that Adam Poisson process with a rate λ A/hour and Brianna Poisson process with a rate λ B/hour.

Here let us consider that Y1 and Y2 be the times at which Adam's first and second emails were sent.

Here we know that the Brianna logs in to the server, you are told that Adam has sent exactly one email so far.

So, here the upper limit while logging is 1. So, the lower limit is 0.

Because these is the real life scenario so the negative value is not applicable.

An assertion that two expressions containing variables or numerical values are equivalent is known as an equation. The first step in resolving a variable equation is to identify the values of the variables that lead to the equality being true. The variables that must be changed in order to solve the equation are referred to as the unknowns, and the unknown values that satisfy the equality are referred to as the equation's solutions.

Given :

Vehicle A: 150 + 0.5m = Cost A

Cost B = 60 + 0.8m for truck B.

Given that a one-day scenario was required by the challenge, the two equations are as follows:

Price B =60+0.8m Price A =150+0.5m

Any equation in algebra that can be written in standard form as where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation. In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler.

Square and quadrangle difficulties have a close relationship with quadratic equations (another name for rectangles). In actuality, the Latin word quadratus, which means square, is the root of the word quadratic.

Any quadratic problem can be solved using the quadratic formula. The equation is first changed to have the form ax2+bx+c=0, where a, b, and c are coefficients. After that, we enter these coefficients into the following formula: (-b(b2-4ac))/(2a).
