What is the length of side AC of the triangle? A=6x + 7 B= 5x + 5 C = 7x - 1
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

Find the domain of the relation represented on the mapping diagram:
3-------> -1
6-------> 4
8-------> 4
Explain how to do it please!!
{3, 6, 8} is the domain of the relation R={(3,-1)(6,4)(8,4)}
What is Function?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
R={(3,-1)(6,4)(8,4)}
All the values in x place are domain values.
The domain equals all of the x values which are r on the left in a ordered pair
x= {3, 6, 8}
Hence {3, 6, 8} is the domain of the relation R={(3,-1)(6,4)(8,4)}

Alexander's hobby is dirt biking. On one occasion last weekend, he accelerated from rest to 10.3m/s in 5.98 seconds. He then maintained this speed for 7.92 seconds. Seeing a coyote cross the trail ahead of him, he abruptly stops in 4.33 seconds. Determine Alexander's average speed for this motion.
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.
What are motion equations?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,
v = u + at v² = u² + 2as s = ut + 1/2at²For 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.

Angle 1=10y+46
Angle 2= 6y+6

What is the domain of the function f(x) - 50 ? 5 + 720-2 {x: 0 < 20) {0, 1, 2, 3,.20} {a: 2 < 20} {0, 1, 2, 3,....19
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:
[tex]\begin{gathered} 5+\sqrt[]{20-x}=0 \\ \sqrt[]{20-x}=-5\longrightarrow\text{ there is no real value for x that will satisfy this condition} \end{gathered}[/tex]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:
[tex]\begin{gathered} 20-x\ge0 \\ 20\ge x \\ x\le20 \end{gathered}[/tex]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}

two sides of a triangle are 18 ft and 23 ft. Find the range for the measure of the third side.
Using the triangle inequality theorem the range of measures of the third side is 5 < x < 41
How to find the third side of the triangle?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

A. 5:30
B. 4:50
C. 6:00
D. 4:10
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

Fill in the blank h(-5) • g(-2) = ________g(x) = x2. h(x) = 3x - 2
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:
[tex]\begin{gathered} g(x)=x^2 \\ g(-2)=(-2)^2=4 \\ \\ h(x)=3x-2 \\ h(-5)=3\cdot(-5)-2=-15-2=-17 \end{gathered}[/tex]Now we can calculate the product of h(-5) and g(-2):
[tex]h(-5)\cdot g(-2)=(-17)\cdot4=-68[/tex]So the value to fill the blank is -68.

Answer:

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.
Triangle inequalityThe 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.
