Solve each equation. x²+11 x=-18

A logarithm is a power that requires a number to be raised to another power. The bases of all the values involved must be identical. So, we must create equivalent expressions in the equation that all have equal bases. And the two expressions then formed can only be said equal if the exponents are also similar. Now we will move towards the solution to the problem.

Solution:

1/3|5x-3|=6

Absolute value equality entered

(1/3) |5x-3| = 6

Clear the absolute-value bars by splitting the equation into two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is (1/3) |5x-3|

For the Negative case, we'll use -(1/3) (5x-3)

For the Positive case, we'll use (1/3) (5x-3)

-(1/3) (5x-3) = 6

Multiply

-5x/3+1 = 6

Rearrange and add up

-5x/3 = 5

Multiply both sides by 3

-5x = 15

Divide both sides by 5

-x = 3

Multiply both sides by (-1)

x = -3

Which is the solution for the Negative Case

(1/3)(5x-3) = 6

Multiply

5x/3-1 = 6

Rearrange and add up

5x/3 = 7

Multiply both sides by 3

5x = 21

Divide both sides by 5

x = (21/5)

Which is the solution for the Positive Case

x=-3

x=21/5

The total distance traveled by the pendulum when it comes to rest is 10,000 cm.

Because of friction and air resistance, each swing of a pendulum is a little shorter than the previous one. The lengths of the swings form a geometric sequence. Suppose the first swing of a pendulum has a length of 100 cm and the return swing is 99 cm .

Now,

Given,

On the first swing, the distance traveled is 100, and on the second swing, the distance is 99.

The first term of the geometric sequence is, a1 = 100

The second term of the sequence is, a2 = 99

The common ratio r = 99/100

Therefore, the expression for the n-t h term of the sequence is:

a_n = 100*(99/100)^(n-1)

Theoretically, using this formula, it would take an infinite number of trips to come to rest.

Hence we need to find the sum of the series a_n = 100*(99/100)^(n-1) from n=1 to n=infinity.

The sum of an infinite series is given by S = a/(1-r) where a=the first term and r=the common ratio.

Therefore,

the total distance traveled is S = 100/(1-(99/100) = 100/0.01 = 10,000 cm

Step-by-step explanation:

The mean of the salary is $120000.

By adding up a list of salaries and dividing by the total number of salaries on the list, mean salaries are derived. This means that exceptionally high and extremely low incomes have the same weight in the final average, which is crucial to bear in mind while investigating industry salaries.

By ranking the wages of a group of employees in descending order, you may determine the median base salary by finding the income that is in the middle of the distribution.

Mean=(5*440,00+2*100,000+1*540,000)/(5+2+1)

         =(220,000+200,000+540,000)/8

         =960,000/8

         =120,000

Median is 100,000.

Hence, the mean salary is 120,000 but 7/8  members salary is lower than 120,000. Because the firm’s owner salary is too high. thus the firm’s owner is so unethical regarding employee salary.

When two arcs are parallel to each other, the two arcs between them are congruent. If the two arcs they intersect are the same length, they are congruent.

Chords within a circle can be related in a variety of ways. Parallel chords cut congruent arcs in the same circle. That is, the arcs whose endpoints include one of each chord's endpoints have equal measures.

The lengths of the arcs connecting two parallel chords of a circle are equal. Similarly, if the lengths of the two arcs connecting two distinct chords are the same, the chords are parallel. If two chords have the same length, the arcs between their endpoints will have the same measure.

The slope of the given points are  (29, 11) and (-3, -7):

= 0.5625.

A line's slope indicates whether sharp it is.. The slope is defined mathematically as "climb overrun" (change in y divided by change in x).

In general, a line's slope indicates its steepness as well as direction. The slope of a straight line connecting two points (x1,y1) and (x2,y2) can be simply calculated by subtracting the coordinates of both the points. The slope is commonly denoted by the letter'm.'

X₁ = 29

Y₁ = 11
X₂ =  -3
Y₂ = -7

The slope is the degree of tilt a line has and it may be positive, negative, zero, or undefined.

slope = (y₂ - y₁) / (x₂ - x₁)

Substituting the value in the given formula:

slope  =  [tex]\frac{(-7 - 11)}{(-3 - 29)}[/tex]

          = -18 / -32

          = -9 / -16

Answer: If (4, y ) is an ordered pair of the function, then y = 1

Step-by-step explanation:

The known x coordinate for the position (4,y) is 4.

We'll just refer to it as y since we don't know the y coordinate just yet.

On the x axis, trace a vertical line through 4 (see related remark below).

Thus in red (see attached image).

The red line crosses the graph at the point (4,1)

so this tells us that,

                                          y = 1

Although it's helpful to see how it turns out, you are not need to draw a vertical red line.

You will be able to visually perceive the solution without these extra lines after you become accustomed to these kinds of situations.

Therefore,

If (4, y ) is an ordered pair of the function, then y = 1

Classifying an equiangular triangle as an acute equiangular triangle is unnecessary because by definition, all angles are 60°

An equiangular triangle is one with three equal sides and three equal angles, all of which are measured at 60 degrees. Given that the characteristics of both triangles are the same, an equiangular triangle can also be referred to as an equilateral triangle.

This triangle is regarded as a regular polygon because its sides and angles are both equal. Equiangular refers to angles that are all equal.

All triangles have 3 angles that together total 180 degrees. Because an equilateral triangle has equal sides, its angles can only be 60 degrees. This entails that all angles must be acute. It is not required to write that it is intense because of this.

Using the segment addition postulate, it is found that:

3. The value of x is of x = 9.5.

4. The value of y is of y = ± 5.

The segment addition postulate is a geometry axiom that states that a line segment, divided into a number of smaller segments, has the length given by the sum of the lengths of the segments.

In item 1, we have that the largest segment is of AC, hence it represents the line, while point B splits the segment into two parts, that is, point B is between the other two.

In item 2, we have that:

For item 3, applying the Postulate, we have that:

AB + BC + CD = AD

4 + 4 + 2x - 6 = 21

2x = 19

x = 9.5.

For item 4, due to the midpoint, we have that:

The total number of signals that can be made using 5 flags from 8 flags of different colors is 6720.

Permutations:

A permutation is an act of arranging the objects or numbers in order.

The formula for permutations is:

nPr = n!/(n-r)!

where

nPr = permutation

n = total number of objects

r = number of objects selected

Combinations:

Combinations are the way of selecting the objects or numbers from a group of objects or collection, and the order of the objects does not matter.

The formula for combinations is:

nCr = n!/[r! (n-r)!]

Where,

nCr  = number of combinations

n = total number of objects in the set

r = number of choosing objects from the set

Given,

Here we need to find how many different signals can be made with 5 flags from 8 flags of different colors.

The number of ways that 5 flags can be selected is the combination of 8 flags taken 5 at a time.

After choosing 5 flags from 8, it can be arranged in

=> ₅P₅ ways = (5!)

Therefore, the total number of signals that can be made is

=> ₈C₅ x  ₅P₅

=> (8!/(8-5)!5!) x 5!

=> (8! / 3!)

=> 40320 / 6

Therefore, the total number of signals that can be made is 6270.
