A unique triangle can be defined as a triangle that can be formed in one way.

The various conditions that a triangle must satisfy so that it is unique :

a) A triangle where the length of the three sides is known or given is a unique triangle.

b) A triangle where two side lengths and their included angle is given is a unique triangle.

c) A triangle where two angles and their included side is given is a unique triangle.

d) A triangle where two angles and a non - included side length is known is a unique triangle.

In the above question, we are given angles 40°, 40° and 100 degrees

3 angles are known, no side length is given. The angles above can form a triangle called the obtuse triangle because their sum = 180° and one of the angles is great we than 90°

However, this does not satisfy the criteria that makes a triangle unique.

Therefore, no unique triangle(s) can be drawn with interior angles measuring 40°, 40°, and 100°.

If the faculty went on a weight watchers diet plan and now weight an average of 185 pounds in 2021.  The faculty's average weight loss per year : 185 pounds and 155 pounds.

First step is to find the difference between the initial weight and the final weight

Difference = Initial weight - Final weight

Difference = 215 pounds - 185 pounds

Difference = 30 pounds

Now let find the lost per year

2018

Lost per year = 215 pounds - 30 pounds

Lost per year = 185 pounds

2021

Lost per year = 185 pounds - 30 pounds

Lost per year = 155 pounds

Therefore the loss is 185 and 155 pounds.

The sentence is true because the expressions are equivalent.

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=7x+3. Where:

m= the slope.

b= the constant term that represents the y-intercept

For the given example: m=7 and b=3.

The linear equations are considered equivalent when they are equal.

The given equations are 5y+4−3y = 2y+4. Solving theses equations, you have:

The number of laddus who were there at the beginning Rohan has is 48.

Here we have to find the number of laddu Rohan at the beginning.

Let x be the number of laddu Rohan have.

He gave on the first day = x × 1/3= x/3

The leftover laddu = x - x/3

= 2x/3

Laddu is given on the second day = 2x/3 × 1/4

= x/6

Here we know that the laddu given by Rohan is 8,

So

x/6 = 8

x = 48

Therefore we get the number of laddu Rohan has 48.

The value of composition of function (goh) (-3) is [tex]\frac{8}{5}[/tex].

A function that depends on another function is referred to as a composite function. When one function is inserted into another, a composite function is produced. The definition of a composite function is a function made up of two functions, one of which acts as an independent variable for the other function. It can be defined as:

[tex](fog)(x)=f(g(x))\\(gof)(x)=g(f(x))[/tex]

Using inequality the number of 105  of 120-kilogram crates that can be loaded into the shipping container.

What is inequality?

A difference between two values indicates whether one is smaller, larger, or simply not equal to the other. In mathematics, the term "inequality" refers to a relationship between two expressions or values that is not equal to one another.

The greatest weight that container can hold = 27500

Shipment weight already  in the container =14900

Amount of weight that may be loaded = 27500 - 14900 = 12600

Weight of each crates = 120 kg

Let x be the maximum number of 120 kg crates that can be loaded to the container then,

Weight of 'x' number of 120 kg crates = 120x

Therefore, the required inequality is as follows

=>120x< 12600

(since the maximum amount of weight of crates that can be put in the container should be less than or equal to the total weight of the maximum number of crates that can be loaded into the container).

Then the inequality is ,

=> x [tex]\leq \frac{12600}{120}[/tex]

=> x ≤ 105.

Step-by-step explanation:

money on clothes is 10%, that means it's $5
you get this by dividing the 50 by 100 to figure out how much 1% is, and then multiply with 10.

money on games is 20%, that means it's $10
again, you figure out how much 1% of 50 is and then multiply by 20 to figure out what 20% is.
50 / 100 = 0.5
0.5 * 20 = 10

So far you spent $5 on clothes, $10 on games, that's $15 in total.
When the rest is spent on books, you need to see how much is left of the $50.
50 - 15 = 35

Using linear approximation, the function y = √33 is approximated as 5.744

The concept behind the linear approximation formula is the equation of a tangent line. We know that the slope of the tangent that is drawn to a curve y = f(x) at x = a is its derivative at that point. i.e., the slope of the tangent line is f'(a). Thus, the linear approximation formula is an application of derivatives. Let us learn more about this formula in the upcoming sections.

What is solution of the equation?

In order to make the equation's equality true, the unknown variables must be given values as a solution. In other terms, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transform the equation into an equality.

(i) cosec x = 1      for 0 ≤ x ≤ 360°

Since, the general solution for

cosec x = 1 is, [tex]x = \frac{\pi }{2} +2n\pi[/tex]

The range for the solution is 0 ≤ x ≤ 360°

Hence,

[tex]x=\frac{\pi }{2} , x= \frac{5\pi }{2} , x= \frac{9\pi }{2} , x = \frac{13\pi }{2} , x = \frac{17\pi }{2}[/tex]

Since, the general solution for

sec x = 1  is, x = 0 + 2πn

The range for the solution is 0 ≤ x ≤ 360°

Hence,

x = 0, x = 2π, x = 4π, x = 6π, x = 8π.

(iii) cot x = 4

⇒ [tex]x = cot^-^1(4)[/tex]

y = 4/7 x + 16/7 + 6

y = 4/7 x + (16+42)/7

y = 4/7 x + 58/7

aₙ = 10 - 5n and a₂₁ = -95

(2) The explicit formula and the 21st term for the second  sequence are:

aₙ = 1.5n + 1.5 and a₂₁ = 33

A sequence in which the difference between any two consecutive terms is the same is known as an arithmetic sequence.

(1)

The given sequence is 5, 0, -5, -10,...

Note the difference between two consecutive terms of the sequence is the same, which is -5.

Therefore, the sequence is an arithmetic sequence with a common difference of d = -5.

The [tex]n^{th}[/tex] term of an arithmetic sequence is given by:

aₙ = a₁ + (n-1)d

Substitute a₁ = 5 and d= -5 into the equation,

aₙ = 5+ (n-1)(-5)

   = 5 - 5n + 5

aₙ = 10 - 5n

To find the 21st term, substitute n = 21 into the above equation,

a₂₁ = 10 - 5n

a₂₁ = 10 - 5(21)

a₂₁ = 10 - 105

a₂₁ = -95

Hence, the explicit formula and the 21st term for the first sequence are:

aₙ = 10 - 5n and a₂₁ = -95

(2)

The given sequence is 3, 4.5, 6, 7.5, 9,...

Note that the difference between two consecutive terms is 1.5, therefore, the sequence is an arithmetic sequence with a common difference of

d = 1.5.

The [tex]n^{th}[/tex] term of an arithmetic sequence is given by:

aₙ = a₁ + (n-1)d

Substitute a₁ = 3 and d= 1.5 into the equation,

aₙ = 3 + (n-1)1.5

aₙ = 3+1.5n-1.5

aₙ = 1.5n+1.5

To find the 21st term, substitute n = 21 into the above equation,

a₂₁ = 1.5(21) + 1.5

a₂₁ = 31.5 + 1.5

a₂₁ = 33

Hence, the explicit formula and the 21st term for the second  sequence are:
