Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

We are Given the following information;

Television camara at 13°

Altitude = 400

Since the formed angle is a 90° angle then we have;

90-13= 77

The trigonometric function that relates Hyp angle and Adj is Cos then

Cos ∅ = Adj /Hyp

where

angle = 77

adj=400

Hyp= The distance from camara to the stadium

then

Cos 77 = 400/Hyp

Hyp = 1778

Give that a5=768 and a2=12, given two terms in a geometric sequence find the 8th term and the recursive formula is ar⁷=6291456

A geometric progression is a type of sequence in which the terms are gotten by the multiplication of a constant term known as the constant ratio

The 5th term = ar⁴ = 768   ...............1

The 2nd term = ar² = 12  ....................2

The value of the angle x in the parallel lines is 20.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angles, alternate exterior angles, linear angles, vertically opposite angles,  same interior angles, same exterior angles etc.

Therefore, a and b are the parallel lines. The parallel lines are cut by a transversal.

Same-side exterior angles are supplementary.

Hence,

5x + 10 + 4x - 10 = 180

5x + 4x  = 180

9x = 180

divide both sides by 9

x = 180 / 9

Answer:

To find the inverse, interchange the variables and solve for y.

[tex]f {}^{ - 1} (x) = {x}^{3} - 7[/tex]

Answer:

y = 2x - 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (5, 7 ) and (x₂, y₂ ) = (3, 3 )

m = [tex]\frac{3-7}{3-5}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2 , then

y = 2x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (3, 3 ) , then

3 = 2(3) + c = 6 + c ( subtract 6 from both sides )

- 3 = c

y = 2x - 3 ← equation of line

A baseball glove or mitt is a large glove worn by baseball players of the defending team, which assists players in catching and fielding balls hit by a batter or thrown by a teammate.

Baseball was initially a glove-less sport. A player who played without gloves during the gradual switch to gloves was referred to as a "barehanded catcher"; this term did not refer to the position of catcher, but rather to the act of catching with bare hands.

The original glove was used mainly to smash a ball to the ground so it could be scooped up and was not webbed or particularly well adapted for catching. Due to a left hand injury, Doug Allison, a catcher for the Cincinnati Red Stockings, is one of the earliest players thought to have used a baseball glove.

Charlie Waitt, a first baseman and outfielder for St. Louis, donned the first known glove in 1875.

The quadratic formula is used to solve a quadratic equation of the form ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable.

Given an equation 25x^2 - 30x + 9 = 0, we can solve it using the quadratic formula as follows:

The quadratic formula is : x = (-b ± √(b^2 - 4ac)) / 2a

The values of a,b,c are:

a = 25, b = -30, c = 9

Now, we can substitute the values in the quadratic formula:

x = (-(-30) ± √((-30)^2 - 4(25)(9)))/2(25)

x = (30 ± √(900 - 900)) / 50

x = (30 ± √(0)) / 50

x = (30 ± 0) / 50

x = 30/50

x = 3/5 or x = -3/5

So the solutions of the equation 25x^2 - 30x + 9 = 0 are 3/5 and -3/5.

a)  m∠? = 48°

If a transversal line intersects two parallel lines, then the resulting alternate interior angles are congruent.

b)  m∠? = 71°

If a transversal line intersects two parallel lines, then the resulting corresponding angles are congruent.

c)  m∠1 = 115°

If a transversal line intersects two parallel lines, then the resulting alternate exterior angles are congruent.

d)  m∠2 = 62°

If a transversal line intersects two parallel lines, then the resulting same-side exterior angles are supplementary.

Step-by-step explanation:

Alternate Interior Angles Theorem

If a transversal line intersects two parallel lines, then the angles that are interior to the parallel lines and on the opposite side of the transversal line are congruent.

If a transversal line intersects two parallel lines, then the resulting alternate interior angles are congruent.

[tex]\implies m\angle ?=48^{\circ}[/tex]

Corresponding Angles Postulate

If a transversal line intersects two parallel lines, then the angles that are corresponding (in the matching corners) are supplementary.

If a transversal line intersects two parallel lines, then the resulting corresponding angles are congruent.

[tex]\implies m\angle ?=71^{\circ}[/tex]

Alternate Exterior Angles Theorem

If a transversal line intersects two parallel lines, then the angles that are exterior to the parallel lines and on the opposite side of the transversal line are congruent.

If a transversal line intersects two parallel lines, then the resulting  alternate exterior angles are congruent.

[tex]\implies m\angle 1=115^{\circ}[/tex]

Same-side Interior Angles Theorem

If a transversal line intersects two parallel lines, then the angles that are interior to the parallel lines and on the same side of the transversal line are supplementary.

If a transversal line intersects two parallel lines, then the resulting same-side exterior angles are supplementary.

The teacher should pay the student 153.

Pay is a form of compensation or remuneration given to an individual in exchange for goods or services. It is typically a monetary amount, but can also be in the form of goods, services, or other benefits. Pay is usually received on a regular basis, such as a salary, wages, or commission, but can also include one-time payments, such as bonuses or severance packages. Pay can also be determined by the amount of time spent working or the amount of work completed.

The student has solved 17 problems correctly, so the teacher should pay them 9 for each one. Therefore, the teacher should pay the student 9 x 17 = 153.

This arrangement is beneficial for both parties involved. The student gets paid for their work, and the teacher receives help with their workload. This type of arrangement is commonly used in educational settings, as it allows the teacher to evaluate the student's understanding of the material while simultaneously being compensated for the help they provide. It is also a great way to motivate the student, as they know they will be rewarded for their hard work.

The temperature of City A and City B on that day was 4°C and 3°C respectively.

The correct answer choice is option B

Let

The temperature of City A = x

The temperature of City B = y

4x = 7 + 3y

x − 3y = −5

From equation (2)

x = -5 + 3y

Substitute into equation (1)

4x = 7 + 3y

4(-5 + 3y) = 7 + 3y

-20 + 12y = 7 + 3y

12y - 3y = 7 + 20

9y = 27

divide both sides by 9

y = 27/9

y = 3

Substitute into (1)

4x = 7 + 3y

4x = 7 + 3(3)

4x = 7 + 9

4x = 16

divide both sides by 4

x = 16/4

x = 4
