The value of θ from the triangle ABC is θ = 6.213°

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be represented as ABC

Now , the opposite side of the triangle AB = 2,000 feet

The hypotenuse of the triangle AC = 3.5 miles

The hypotenuse of the triangle AC = 3.5 x 5,280

The hypotenuse of the triangle AC = 18,480 feet

Now , from the trigonometric relations ,

sin θ = opposite / hypotenuse

Substituting the values in the equation , we get

sin θ = 2000 / 18480

On simplifying the equation , we get

sin θ = 0.108225

Taking inverse on both sides of the equation , we get

θ = sin⁻¹ ( 0.108225 )

θ = 6.213°

Hence , the value of θ is 6.213°

A line has a slope of –9 and includes the points (–7,u) and (9,9).

The value of u is 153.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Given:

A line has a slope of –9 and includes the points (–7,u) and (9,9).

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

-9 = (9 - u)/(9 + 7)

-9 = (9- u)/16

9 - u = -144

u = 153.

Therefore, the value of u is 153.

Answer:

∠ LKH = 25°

Step-by-step explanation:

LK is the midsegment of Δ FGH

LK joins the midpoints of the sides FH and GH and is parallel to the third side FG.

Then

∠ LKH = ∠ FGH = 25° ( corresponding angles )

The angle 4 is equal to 98degree.

Two angels whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

Given;

m∠3=82

Now

m∠3+m∠4=180      (since the angles are supplementary)

82+m∠4=180

m∠4=180-82

m∠4=98degree

Therefore, the angle 4 will be 98degrees.

A. 9 students offer all three subjects.

B. The only possible value of m is 8.

A. We can use the Principle of Inclusion-Exclusion (PIE) to find the number of students who offer all three subjects.

Let's call the number of students who offer all three subjects "x".

The total number of students who offer Biology is 35, but we have to subtract the number of students who offer only Biology and Economics (12) and only Biology and Physics (7) to avoid counting them twice.

So, the number of students who offer Biology only is 35 - 12 - 7 + x = 16 + x.

Similarly, the number of students who offer Economics only is 28 - 12 - 5 + x = 11 + x.

And the number of students who offer Physics only is 15 - 7 - 5 + x = 3 + x.

The total number of students who offer at least one of the three subjects is 58, so:

16 + x + 11 + x + 3 + x = 58

30 + 3x = 58

3x = 28

x = 9

So, 9 students offer all three subjects.

B. In a regular polygon with (2m + 1) sides, each interior angle is equal to (2m + 1 - 2) * 180 / (2m + 1) = (2m - 1) * 180 / (2m + 1).

We know that this value is equal to 1440, so:

(2m - 1) * 180 / (2m + 1) = 1440

Expanding the right side:

2m - 1 = 1440 * (2m + 1) / 180

Dividing both sides by (2m + 1) and rearranging:

2m = 1440 * 2 / 180 + 1

2m = 16 + 1

m = 8.5

Since m must be a positive integer, the only possible value of m is 8.

The limit of the infinite series diverges and the limit goes off to infinity

If a series is convergent then it has bounded partial sums. Equivalently, if a series fails to have bounded partial sums then it is divergent.

When the series' limits reach its finite range of values, the series is said to be convergent. It is important that, partial sum of series, there should be a limit existed and that is finite in nature then only series converges

An infinite series is one that doesn't converge at any point , had a series of incomplete sums that went on forever and had no end. A series diverges when each sum does not approach zero.

Given data ,

Let the infinite series be represented as A

Now , the value of A is

A = ∑n=1 to ∝ ( 3n⁴ / ( 15n⁴ + 5 )

On simplifying the equation , we get

A = 3 ∑n=1 to ∝ ( n⁴ / ( 15n⁴ + 5 )

Number of rainbow shiner = 30

To find,

The ratio of sunfish to rainbow shiner.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Ratio of sunfish to rainbow shiner :

= Number of sunfish : Number of rainbow shiner

= 12 : 30

= 6 : 15

= 2 : 5

(This ratio cannot be for the simplified so we will have to assume this as the final answer of this question.)

Hence, the ratio is 2:5

Answer:

2:5

Find the number both sides can be divided by in this case, it is 6. Diving both sides by a common number gives us 2 from 12 and 5 from 30.

Answer: A: 3/10 of the school has blonde hair. B: there are 120 students

Step-by-step explanation: I might have done this wrong but anyway, I multiplied 2/5 by 1/4 and got 1/10, meaning 1/10 of the boys have blonde hair. I multiplied 3/5 (because 5/5 - 2/5 = 3/5) by 1/3 and got that 2/10 of the girls are blonde. I added these, and got that 3/10 of the school are blondes. That's A. Then, I set up the equation 3/10 = 36/x (x equals the total number of students in the school). When I solved it I got x = 120, meaning there are 120 students in the school.

Domain of the function is all real numbers

A relation is a function if it has only One y-value for each x-value.

Let us consider a function f(x)= x² + 2x - 3

Now let us find the value of f(x-3)

Plug in the value x as x-3

f(x-3)= (x-3)² + 2(x-3) - 3

= x² +9-6x+ 2x-6 - 3

= x² -4x

The domain of this function is all real numbers. This means that any real value can be plugged into the function and produce a real output.

On solving the provided question, we can say that so, the Interest Rate to be paid will be as = 5.08%

Simple interest is calculated by dividing the principal by the interest rate, the passage of time, and other elements. The formula used in marketing is simple return = principal + interest + hours. Using this approach, interest may be calculated most easily. The most common way to calculate interest is as a percentage of the principal balance. If he borrows $100 from a friend and agrees to pay it back with 5% interest, for instance, he will only pay his proportion of the 100% interest. $100 (0.05) = $5. You must pay interest when you borrow money and charge interest when you lend it. The majority of the time, interest is calculated as an annual percentage of the loan balance. This proportion is referred to as the loan's interest rate.

Interest Rate =($ Paid in Interest / $ Amount borrowed) X (360 / borrowed period)

= ($33 / $2600) X (360 /90)

Answer:

x = - 5/9

Step-by-step explanatiion:

8x-8+3(2x+2) = -4(x+3) is the original equation

Consider each term and simplify

3(2x+2) = 6x + 6

-4(x + 3) = -4x - 12

Therefore the original expression becomes:
8x - 8 + 6x + 6 = -4x - 12

Move -4x to the left side; becomes + 4x
4x + 8x - 8 + 6x = -12

Group like terms on left side and simplify
(4x + 8x + 6x) (-8 +6) = -12

18x - 2  = - 12

Move -2 to right side -> becomes +2

18x = 2 - 12 = - 10

x = -10/18 = - 5/9

The equation of the line of Kaya’s line in slope-intercept form is y = 15x  + 25.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given this, Kaya babysits to add money to her savings. She draws a graph to show how much she can earn by babysitting.

To calculate the equation of the line we at least need Two points on the line.

Two points on the graph (0, 25) and (5, 100) and also the y-intercept of the given line is 25(where x is 0)

From the general formula of the slope-intercept form of an equation:

y=mx+b,

where m is the slope

b is the y-intercept,

Since. m = (y - y')/ (x -x')

In our case m = (100 - 25)/5-0)

m = 75 /5

m = 15

and b = 25

Thus, the equation of a line:

y = 15x  + 25

Therefore, The equation of the line of Kaya’s line in slope-intercept form is y = 15x  + 25.
