The domain of a function f(x) is the set of values of the variable x for which the function is defined (has a defined finite value).

In the case of rational functions like this one, the function becomes undefined when the denominator is 0, so we can write:

As the square root will only give positive values or zero, there is no value of x that will make the square root be equal to -5. Then, this condition does not give us any discontinuity for f(x).

We have now to consider that the square root of (20-x) will not accept negative arguments in order to be in the realm of real numbers. So then, we have the condition:

Then, f(x) will not be defined for x that do not satisfy this condition.

We can conclude that f(x) is defined for all values of x that are equal or less than 20.

Answer: The domain is {x: x<=20}

The value of sin ∠A in the right triangle is 3 / 5

A right triangle is a triangle that has one of its angles as 90 degrees.

Base on the angles, the side of a right triangle can be named as follows:

Using trigonometric ratio, sin ∠A can be found as follows:

sin ∠A = opposite / hypotenuse

Hence,

opposite side = 3

hypotenuse side = 5

Therefore,

sin ∠A = 3 / 5

Step-by-step explanation:

The first step to solve this question is to find the values of h(-5) and g(-2)

In order to do that, you need to use the value of x=-5 in the function h(x) and x=-2 in the function g(x).

So we have that:

Now we can calculate the product of h(-5) and g(-2):

So the value to fill the blank is -68.

when the minute hand rotated through 1260° time will became 5:30 PM

Complete angle:-

                             A complete angle is a type of angle that measures 360°.A complete angle deals with one full rotation measuring 360°.

      In an hour or in 60 minute, minute hand covers a 360° angle.

   According to question,

                              initially it is 2:00PM,that is minute hand at 12 and hour hand at 2

       it is given that minute hand has rotated through 1260°

                        1260° = 3 x 360° + 180°

                                                             which means minute hand will have three complete rotation and one half rotation.

            when minute hand rotated through 360° angle then hour hand will move from 2 to 3.

              And again in second rotation, when minute hand rotated through 360° angle then hour hand will move from 3 to 4.

             Again in third rotation, when minute hand rotated through 360° angle then hour hand will move from 4 to 5.

           As of now, minute hand have taken three complete rotation and so hour hand reached at 5

                 Now, when minute hand rotated through 180° (one half rotation),minute hand will reach at 6 from 12.

           So, right now the position of hour hand is between 5 and 6 and the position of minute hand at 6.

            hence,  time will be 5:30 PM

The measure of the angles is m∠SAU= 24°

The incenter is the point at which all of the attitude bisectors meet in the triangle, like within the video. It is not always the middle of the triangle.

In triangle ABC, V is the incenter of the triangle.

Since, m∠SAV = 26°

And m∠SBV = 2(m ∠SAV)

                    = 2 × 26°

                    = 52°

Since Property of the incenter of a triangle;

Therefore, DG = EG = GF = 10

Since, m∠A + m∠B + m∠C = 180°

2(18)° + 34° + 2(m∠SAU) = 180°

2(m∠SAU) = 180° - 132°

m∠SAU= 24°

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

A function has three important parts, domain, codomain and Range.

The domain of the relation R is the set of arguments i.e. first members of each ordered pair and the codomain is the set of which the values i.e. second members of all the ordered pairs.

In the Given relation

In mathematics, the triangle is a closed polygon shape which has three vertex as well as three sides. It consist of three forms depending upon the sides. If all the sides are different then it is scalene otherwise equilateral triangle.

According to the question, the given triangle parameters are as follows:

AC = 6 cm; AB = 15 cm; BC = 9 cm;

Using Pythagoras theorem, the right angle property can be checked:

Let us assume the triangle ABC, with three sides:

Answer:

  not a triangle

Step-by-step explanation:

You want to know if side lengths AC=6 cm, AB = 15 cm, and BC = 9 cm will define a right triangle.

The triangle inequality requires the sum of the two shortest sides of a triangle exceed the length of the longest side. Here the requirement for the given lengths to form a triangle is ...

  6 cm + 9 cm > 15 cm . . . . . . . . false

The given side lengths do not satisfy the triangle inequality, so do not form any kind of triangle.

__

Additional comment

Side lengths of a right triangle will satisfy the Pythagorean theorem, so that would be the test for a right triangle. We used the triangle inequality here, because we noticed the short sides add up to the long side. We need go no further, because these lengths do not even form a triangle.

Using the triangle inequality theorem the range of measures of the third side is 5 < x < 41

The triangle inequality theorem states that any side of a triangle must be shorter than the other two sides added together.

In other words, the triangle inequality theorem describes the relationship between the three sides of a triangle. According to this theorem, for any triangle, the sum of lengths of two sides is always greater than the third side.

Therefore, for a triangle that has the sides a, b and c will follow the principle below:

c < a + b

b < a + c

a < b + c

Therefore, the triangle has two sides as 18 ft and 23 ft. The range of the third side is as follows:

x < 23 + 18; x < 41

18 < 23 + x

23 < x + 18

Therefore, base on the first and third inequality.

x < 41

x > 5

Answer:

larger angle=113

smaller angle=67

Step-by-step explanation:

8x+3=a(Vertically opposite angle)

a+14x+1=180°(Angles between parallel line)

8x+3+14x+1=180°

22x+4=180°

22x=176°

x=8

ok it literally shows on the figure the length of the side AC is 6x + 7.

Answer:

AC = 25 units

Step-by-step explanation:

since ∠ A and ∠ C are congruent then the 2 legs BC and AB are congruent

BC = AB ( substitute values )

7x - 1 = 5x + 5 ( subtract 5x from both sides )

2x - 1 = 5 ( add 1 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Then

AC = 6x + 7 = 6(3) + 7 = 18 + 7 = 25

Using the equation of motion, it can be determined that Alexander travels at an average speed of 37.73 m/s while operating a bike.

Equations of motion are equations that explain how a physical system behaves in terms of how its motion changes over time.

The three equations are,

For the initial 5.98 seconds, initial velocity = 0, acceleration = 10.3 m/s and time taken = 5.98 s

Using first equation of motion,

v = u + at

v = 0 + 10.3(5.98) = 61.594 m/s

He then kept this speed up for 7.92 seconds.

For the last 4.33 seconds, final velocity = 0, initial velocity = 61.594 m/s

Acceleration = (0-61.594)/4.33 = -14.224 m/s

Distance travelled in 5.98 seconds is given as follows:

s = u t + 1/2(at²)

= 0 + 1/2(10.3)(5.98)²

= 184.16 m

Distance travelled in 7.92 seconds = 61.594 × 5.98 = 368.33 m

Distance travelled in 4.33 seconds is given as follows:

s = u t + 1/2(at²)

s = 61.594(4.33) + 1/2(-14.224)(4.33)²

= 133.35 m

Total distance travelled = 184.16 + 368.33 + 135.35 = 687.84 m

Average speed = Total distance/Total time = 687.84/(5.98+7.92+4.33)

= 37.73 m/s

Therefore, average motion speed for Alexander while riding a bike is 37.73 m/s which is calculated by using the equation of motion.
