The value of sin(80) cos(20°) - cos(80°) sin(20°)= √3/2

Trigonometry the area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six common trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and abbreviations.

Given:

sin(80) cos(20°) - cos(80°) sin(20°)

Using Trigonometric identity

sin ( A- B) = sin A cos B - cos A sin B

So, sin(80) cos(20°) - cos(80°) sin(20°)

= sin (80 - 20)

= sin 60

= √3/2

Hence,  sin(80) cos(20°) - cos(80°) sin(20°)= √3/2

Step-by-step explanation:

Given

List of options

Required

Select which is equal to 60 when h = 3

To do this, we simply substitute 3 for h in all of the options.

1.

[tex](h + 1)^3 - 4[/tex]

[tex](3 + 1)^3 - 4[/tex]

[tex]4^3 - 4[/tex]

[tex]64 - 4[/tex]

[tex]60[/tex]

Hence:

[tex](h + 1)^3 - 4= 60[/tex]

2.

[tex](4h)^2 + 36[/tex]

[tex](4*3)^2 + 36[/tex]

[tex](12)^2 + 36[/tex]

[tex]144 + 36[/tex]

[tex]180[/tex]

Hence:

[tex](4h)^2 + 36=180[/tex]

3.

[tex]4h^2 + 24[/tex]

[tex]4*3^2 + 24[/tex]

[tex]4 * 9 + 24[/tex]

[tex]36 + 24[/tex]

[tex]60[/tex]

Hence:

[tex]4h^2 + 24 = 60[/tex]

Answer:

It would be an acute scalene triangle

Step-by-step explanation:

All angles measures are less than 90 so it would be acute. No sides are equal so it would be scalene.

We can classify this triangle as Scalene Acute triangle.

We have a triangle angle measures of 82, 75 and 23 and no sides equal (congruent) in length.

We have to classify this triangle.

A triangle is a plane figure with three straight sides and three angles.

According to question, we have -

A triangle with no side congruent and all angles acute and unequal.

If all the three sides of a triangle are of same length, then the sides are said to be congruent. In an Equilateral triangle all the sides are congruent. Similarly, a triangle with none of its sides equal or congruent is called a Scalene triangle. An acute angle triangle (or acute-angled triangle) is a triangle in which all the interior angles are acute angles i.e. 0 < [tex]\theta[/tex] < 90. Therefore, it is a Scalene acute triangle.

Hence, we can classify this triangle as Scalene Acute triangle.

Let's solve the problem from end to beginning.

Martin collected 2 1/2 bags of clothes for a clothing drive. This mixed fraction can be expressed as:

[tex]2\frac{1}{2}= 2+\frac{1}{2}=\frac{5}{2}[/tex]

Sue collected 1/5 as many clothes as Martin did. This means she collected:

Answer:

The 50th score is 46.

Step-by-step explanation:

Given that

[tex]a_{50} = 26.4\\a_{49} = 26\\n_1 = 50\\n_2 = 49[/tex]

In order to find the 50th score we have to find sum of 49 values and 50 values and then subtract them.

Average is given by the formula:

[tex]Average = \frac{Sum}{Number\ of\ values}\\[/tex]

Using this formula, we can calculate sum for both averages

So,

[tex]a_{50} = \frac{s_{50}}{n_1}\\26.4 = \frac{s_{50}}{50}\\26.4*50 = s_{50}\\s_{50} = 1320[/tex]

And

[tex]a_{49} = \frac{s_{49}}{n_2}\\26.4 = \frac{s_{49}}{49}\\26*49 = s_{49}\\s_{49} = 1274[/tex]

Now for the 50th score,

[tex]50th\ score = s_{50} - s_{49} = 1320-1274 = 46[/tex]

Hence,

The 50th score is 46.

Answer: y=2x-1

Step-by-step explanation:

Equation of a line that passes through (a,b) and have slope m is given by :-

[tex](y-b)=m(x-a)[/tex]   [point slope form]

Given, Point = (4,7)  , m= 2

Equation in point slope form :   [tex](y-7)=2(x-4)[/tex]

To write in slope intercept form (y=mx+c) , we need to simplify it

[tex]y-7= 2x-8\\\\\Rightarrow\ y-2x=-8+7\\\\\Rightarrow\ y-2x=-1\\\\\Rightarrow\ y=2x-1[/tex]

Hence,  y=2x-1

Answer:

The correct answer is:

Option A: A 10x — 15000 ≥ 50000

Step-by-step explanation:

Given that the total cost of manufacturing by the company is $15000.

Let x be the number of gallons the company sells.

It is also mentioned that the company earns $10 on each gallon.

So the total profit will be the the difference of the selling cost of gallons and manufacturing cost

Mathematically,

[tex]10x-15000[/tex]

Now it is mentioned that the profit should be at least 50000 dollars which means the profit can be minimally 50000 and also can be greater than it so

[tex]10x-15000 \geq 50000[/tex]

The number of gallons can be found by solving the obtained inequality.

Hence,

The correct answer is:

Option A: A 10x — 15000 ≥ 50000
