The 10th term of the geometric sequence is -1/6.

Let the following be a geometric sequence:

    a(1), a(2), a(3), a(4), a(5), ....

Then we have:

a(2) = a(1) . r

a(3) = a(2) . r

Continue the process, we have

a(n) = a(n-1) . r

Where:

a(n) = nth term

a(n-1) = (n-1)th term

r = ratio

In the given problem, a(9) = -1/3, r = 1/2

Plug these into the above formula:

a(10) = a(9) . r

        = (-1/3) . 1/2 = -1/6

The Least Common Multiple (LCM) of A and B is 11,741,730 and the Highest Common Factor (HCF) of A and B is 10

The least common multiple is also known as LCM (or) the lowest common multiple in math. The least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.

The highest common factor of two or more numbers is the highest number among all the common factors of the given numbers. It is also known as HCF.

So, Given numbers LCM of A and B can be calculated by

Listing all prime factors for each number.

Prime Factorization of A is:

2 x 3 x 5 x 11 x 13

Prime Factorization of B is:

2 x 5 x 7 x 17 x 23

The new superset list is

2, 3, 5, 7, 11, 13, 17, 23

Multiply these factors together to find the LCM.

LCM = 2 x 3 x 5 x 7 x 11 x 13 x 17 x 23 = 11741730

Now, Given numbers HCF of A and B can be calculated by

The factors of A are: 1, 2, 3, 5, 6, 10, 11, 13, 15, 22, 26, 30, 33, 39, 55, 65, 66, 78, 110, 130, 143, 165, 195, 286, 330, 390, 429, 715, 858, 1430, 2145, 4290

The factors of B are: 1, 2, 5, 7, 10, 14, 17, 23, 34, 35, 46, 70, 85, 115, 119, 161, 170, 230, 238, 322, 391, 595, 782, 805, 1190, 1610, 1955, 2737, 3910, 5474, 13685, 27370

Then the greatest common factor is 10.

The equation of the line in point-slope form, which passes through the pair of points located at (1 , 9) and (6 , 2), is y - 9 = -7/5(x - 1).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Getting the slope of the two points: (1 , 9) and (6 , 2).

m = (y2 - y1)/(x2 - x1)

m = (2 - 9)/(6 - 1)

m = -7/5

Using the point slope form, plug in the values of the slope and one point to set up the equation.

(y - y1) = m(x - x1)

where m = -7/5 and (x1 , y1) = (1 , 9)

(y - 9) = -7/5(x - 1)

y - 9 = -7/5(x - 1)

Lets look at the expressions with respect to the competition parameters: Expressions:You Y =3m+13Friend(F)=4m+6 1.  The competition begins AFTER you and friend already caught some flies.  This would be represented by the CONSTANT terms in each expression (in this case, 13 for you, 6 for friend). So the number of flies caught BEFORE THE COMPETITION would be   13+6=19 flies total  2.  The competition length was "m" minutes long when flies are caught and counted.  This would be represented by the VARIABLE terms in each expression (in this case, 3m for you, 4m for friend).  We are not given a numeric value for the variable "m" to evaluate. So the number of flies caught DURING THE COMPETITION (timed "m" minutes long) would be 3m+4m=7m flies total ...and the number of flies per minute would be calculated as 7m÷m=7 flies per min....total #flies divided by total minutes 3.  If the problem asked for the total number of flies caught by you and friend, before and after the competition 7m+19 flies total add like terms in each expression.

Answer:

(2, 7 )

Step-by-step explanation:

y = 3x + 1 → (1)

5x = y + 3 → (2)

substitute y = 3x + 1 into (2)

5x = 3x + 1 + 3

5x = 3x + 4 ( subtract 3x from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

substitute x = 2 into (1)

y = 3(2) + 1 = 6 + 1 = 7

solution is (2, 7 )

The measure of the length of BC from the expression is 8

The segment addition postulate in geometry is the axiom which states that a line segment divided into smaller pieces is the sum of the lengths of all those smaller segments.

Given the following segments

AB = 7

AD = 25 and:

CD = 10

Using the addition postulate below:

AB+BC+CD = AD

Substitute the given parameters

7+BC+10 = 25

17+BC = 25

Subtract 17 from both sides

Probability is the degree to which an occurrence is likely to take place, as determined by the proportion of favorable examples to the total number of instances for which it is probable to have occurred.

Let's assume

1 - P(no one has the same sign) >= 0.5

P(two or more people have the same sign) = 1 - P(no one has the same sign)

= 1 - (12 / (12-n)) / 12^n

1-0.5=0.5 >= P (no one has the same sign) = 12/(12^n x (12-n))

0.5 >= 12 /(12^n x (12-n))

You will  need 12.5 gallons of the 22% salt solution and 7.5 gallons of the 38% of the salt solution

Step-by-step explanation:

.22x + .38(20 -x) = .28(20)  I want to clear the decimal, so I will multiple through by 100

100[.22x + .38(20-x)] = [.28(20)]100

22x + 38(20-x) = 28(20)  Distribute the 38

22x + 760 -38x = 560 combine the x's

-16x + 720 = 560 Subtract 720 from both sides

-16x = -200  Divide both sides by -16

x = 12.5

20 - 12.5 = 7.5

There are two parts to our question.

In the first part of the question, we are asked whether the given list of numbers is a sequence or a series.

To answer this part, we should be familiar with what the concept of sequence and series.

A sequence is a plain list of numbers.

A series is a sum of numbers in the list.

The given list looks something like this,

5+10+ . . . . . . +25

So, considering the given definitions of both sequence and series we can clearly tell it is a series.

Now up to the second part of the question, is the given series finite or infinite?

The numeric values of the function f(x) = 5x - 7 are given as follows:

a) f(-2) = -17.

b) f(1/2) = -9/2.

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the function is not 100% visible from the picture, but we are going to suppose it is given by:

f(x) = 5x - 7.

At x = -2, the numeric value is:

f(-2) = 5(-2) - 7 = -10 - 7 = -17.

At x = 1/2, the numeric value is:

f(1/2) = 5(1/2) - 7 = 5/2 - 14/2 = -9/2.

The simplification by combining like terms of 7s -s  is 6s.

According to the given question.

We have an expression 7s - s.

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression

7s - s.

Here 7s and s both are the like terms.

So, we subtract coeffcients of s to simplify the given expression.

Therefore, the simplification of the expression 7s - s is given by
