What are Trigonometric Functions?

The functions of an angle in a triangle are known as trigonometric functions, commonly referred to as circular functions. In other words, these trig functions provide the relationship between a triangle's angles and sides.

There are five fundamental trigonometric functions: sine, cosine, tangent, cotangent, secant, and cosecant.

Function of Sine

The ratio of the opposing side's length to the hypotenuse is known as an angle's sine function. According to the diagram above, sin is worth:

Sin a =Opp/Hypo = CB/CA

Function of Cosine

The cosine of an angle is the ratio of the neighbouring side's length to the hypotenuse's length. The cos function will be derived as follows from the diagram up top.

Cos a = Adjacent/Hypotenuse = AB/CA

The point zero represents option (A) the location of the starting line

Here, -35 represents the starting location of a race car that is 35 yards behind the starting line.

Therefore, the location of the starting line = starting location of a race car that is 35 yards behind the starting line + 35

Substitute the values in the equation

The location of the starting line =  -35 + 35

The cost of 6 bottle juice is $4.26.

What is cost?

A cost is the value of money that has been expended to produce something or provide a service and is therefore no longer available for use in production, research, retail, and accounting. In the case of an acquisition cost, the money spent on the acquisition is considered the cost.

Given:

Andrew buys 8 bottles of cranberry juice at the corner store for a total cost of $5.68.

So, the cost of each bottle is,

$5.68/8 = $0.71

Now to find the cost of 6 bottle of juice.

6 x $0.71 = $4.26

Hence, the cost of 6 bottle juice is $4.26.

Answer:

If Doug has $100,000 in a savings account that earns 13% interest per year and the interest is not compounded, then after four years he will earn $52,000 in interest. This is because 13% of $100,000 is $13,000, and since the interest is not compounded, this amount will remain constant for each year. Therefore, after four years Doug will earn a total of $13,000 + $13,000 + $13,000 + $13,000 = $52,000 in interest.

In general, if a savings account earns x% interest per year and the initial amount in the account is y dollars, then after n years the account will earn n * (x/100) * y dollars in interest. For example, if the interest rate is 13% and the initial amount is $100,000, then after four years the account will earn 4 * (13/100) * $100,000 = $52,000 in interest.

Answer:

Mr. Conners will use 144 fence posts.

Step-by-step explanation:

Given question is incomplete; please find the question attached herewith.

As we can see from the attachment, Mr Corner's yard is in the rectangular shape.

Total distance around the yard = Perimeter of a rectangle = 2(Length + width)

Length of the yard = 330 ft

And width of the yard = 102 ft

So perimeter of the yard = 2(330 + 102                                         = 864 f

Mr. Conners wants to put a fence post at every 6 feet.

So number of posts used =

                                   =

                                         = 144

Answer:

Area of a rectangle = width x length

Area = (3/8) x (3/7) = 9/56

Mutiplying fractions is easy, just multiply the numerator, then multiply the denominator.

The expression of the inequality is -0.96 ≤ 0.3x and the solution will be x ≥ -3.2 thus, option (D) is correct.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

As per the given,

-0.96 ≤ 0.3x

Divide by 0.3 into both sides of the above equation,

-0.96/0.3 ≤ x

x ≥ -3.2

The number line goes from -3.2 to the positive or greater than -3.2 in the last option.

Hence "The solution of the inequality -0.96 ≤ 0.3x is x ≥ -3.2".

Answer:

To simplify this expression, we need to combine like terms. To do that, we need to combine terms that have the same variables raised to the same powers.

First, we will combine the terms in the first set of parentheses:

(4m²n² + 6m²n)

We see that the terms have the same variables, m and n, and the same powers, 2 and 1, respectively. We can combine these terms by adding their coefficients:

(4m²n² + 6m²n) = (4 + 6)m²n = 10m²n

Next, we will combine the terms in the second set of parentheses:

(8m²n^ - 7m²n² - 13m²n)

In this case, we see that the first two terms have the same variables and powers, so we can combine them by adding their coefficients:

(8m²n^ - 7m²n² - 13m²n) = (8 - 7)m²n^ - 13m²n = m²n^ - 13m²n

We can then combine the remaining term with the first term in the expression:

m²n^ - 13m²n + 10m²n = m²n^ + (-13 + 10)m²n = m²n^ - 3m²n

Finally, we will combine the terms in the third set of parentheses:

(14m²n - 2m^n² + 9m²n)

In this case, we see that the first two terms have the same variable and power for the m variable, but the powers of the n variable are different. Since we cannot combine these terms, we will need to leave them as is. We can, however, combine the remaining term with one of the other terms:

(14m²n - 2m^n² + 9m²n) = 14m²n - 2m^n² + (9 + (-14))m²n = 14m²n - 2m^n² - 5m²n

We can then combine this expression with the previous one:

14m²n - 2m^n² - 5m²n + m²n^ - 3m²n = (14 - 1)m²n - 2m^n² - (5 - 3)m²n = 13m²n - 2m^n² - 2m²n

Finally, we have simplified the expression as much as possible:

(4m²n² + 6m²n) - (8m²n^ - 7m²n² - 13m²n) - (14m²n - 2m^n² + 9m²n) = 13m²n - 2m^n² - 2m²n

Angle K has  a value of 63 degrees.

Given,

The triangle KLM

Angle L = 4x + 7

Angle K = 6x - 9

Angle M = 118° (Exterior)

We have to find the value of angle K.

Here,

Angle M (Interior) = 180 - 118 = 62° (linear pair of angles)

Now,

Angle L + Angle K + Angle M = 180° (Sum of interior angles of a triangle)

Then,

4x + 7 + 6x - 9 + 62 = 180

10x - 2 + 62 = 180

10x  + 60 = 180

10x = 180 - 60

x = 120/10

x = 12

You need to plug in the value for [tex]a_{1}[/tex] which is just the first value in your sequence. As well as [tex]n[/tex] which is the term your looking for, in this case it's 48. Lastly [tex]d[/tex] which is the amount that the pattern is increasing or decreasing by. If the sequence is increasing then the [tex]d[/tex] is positive but if the sequence is decreasing then the [tex]d\\[/tex] is negative.

The combined area of the shaded triangles in figure one is 2ab. We have four congruent right triangles given, with legs a and b. The formula to calculate the area of a right triangle is (leg * leg) / 2. So the area of one of the triangles is ab/2. We have four of these triangles, so ab/2 * 4 = 2ab.

The area of the unshaded square in figure one can be represented as c^2. Since the side of the square is given as c, its area must be c^2 (calculate the area of a square by multiplying its side length by itself).

The combined area of the unshaded squares in figure 2 can be represented by a^2 + b^2. Again, we find the areas of each square by multiplying the side lengths togther: (a * a) + (b * b) = a^2 + b^2.

Finally the areas of the squares in figure one and figure two show that a^2 + b^2 = c^2. This is because the shaded triangles in figure one take up the same area as that of figure two. And since the total figure areas are the same, the unshaded parts of each figure must be equal to each other. Therefore, we have a^2 + b^2 = c^2. This is also known as the Pythagorean Theorem.

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Let the ratio of number of songs downloaded by Gerald and Harold be =

3 : 7

Let the ratio of number of songs downloaded by Harold and James be =

14 : 15

So , the number of songs downloaded by Gerald = 3x

The number of songs downloaded by Harold = 7x

And ,

The number of songs downloaded by Harold = 14y

The number of songs downloaded by James = 15y

So , substituting the values in the equation , we get

7x = 14y

x = 2y

And ,

The number of songs downloaded by Gerald = 3 x 14 z

The number of songs downloaded by Gerald = 42z

The number of songs downloaded by Harold = 7 x 14z

The number of songs downloaded by Harold = 98z

The number of songs downloaded by James = 7 x 15z

The number of songs downloaded by James = 105z

So , the ratio of the number of songs Gerald , Harold and James downloaded = 42z : 98z : 105z

On simplifying the proportion , we get

The ratio will be = 42 : 98 : 105

Hence , The ratio of the number of songs Gerald , Harold and James downloaded is in the ratio 42 : 98 : 105
