The common ratio is 18/23.

What is the geometric sequence?

A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a fixed number, called the common ratio. To find the common ratio of a geometric sequence, we can divide each term by the previous term.

It's important to note that in a geometric sequence, the quotient of any two consecutive terms is always constant and that is the common ratio.

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. Its general term is.

aₙ= a₁ rⁿ⁻1. The value r is called the common ratio. It is found by taking any term in the sequence and dividing it by its preceding term.

Given the geometric sequence: 28, 23, 18

We can find the common ratio by dividing each term by the previous term:

r = 23/28 = 18/23

Therefore, the common ratio is 18/23.

The perimeter of the triangle formed by ABC is 26.56

A coordinate system is a method for determining how to position points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more integers, or coordinates.In order to make it simple to identify the points, a cartesian plane divides the plane space into two dimensions.

Here,

The coordinate plane is another name for it. The horizontal x-axis and the vertical y-axis are the two axes of the coordinate plane. The origin is the place where these coordinate axes connect, and they split the plane into four quadrants (0, 0). Additionally, each point in the coordinate plane is denoted by the coordinates (x, y), where x represents the point's location in relation to the x-axis and y represents its position in relation to the y-axis.

The points on the plane are

A (1,-2) , B(8,-5) and C (5,5)

The length of AB is

=> (81)2+(-5+1)2 = √72 +42

= √65

The length of BC is

Answer:

(f ⋅ g)(3) = 100, the distance in miles the bus traveled

Step-by-step explanation:

The product of (miles/hour) and (hours) is (miles), so only answers with units of distance are applicable. The numbers are ...

 f(3) = 2·3² +2 = 20 . . . . miles per hour

 g(3) = 3+2 = 5 . . . . hours

so (f·g)(3) = f(3)·g(3) = 20·5 = 100 . . . . miles

Answer:

(f ⋅ g)(3) = 100, the distance in miles the bus traveled.

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=2x^2+2\\g(x)=x+2\end{cases}[/tex]

To calculate the composite function (f ⋅ g)(3), multiply function f(3) by function g(3).

[tex]\begin{aligned}(f \cdot g)(3)&=f(3) \cdot g(3)\\&=(2(3)^2+2)(3+2)\\&=(2(9)+2)(3+2)\\&=(18+2)(3+2)\\&=(20)(5)\\&=100\end{aligned}[/tex]

If function f(x) represents the rate of a bus travelling in miles per hour,

and function g(x) represents the time the bus travelled in hours:

[tex]\implies f(x) \cdot g(x)=\rm miles/hour \cdot hour=\dfrac{miles}{hour} \cdot hours=miles=distance[/tex]

Therefore, (f ⋅ g)(3) = 100 represents the distance in miles the bus traveled.

option A The inequity x ≥   3 indicates how many days it will take Rebecca to finish her orders.

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal symbol (). Different inequalities are used to contrast values, no matter how small or large. Many simple inequalities can be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

Answer:

x=18

Step-by-step explanation:

We know that triangle ABC is similar to triangle ADE, so therefore the proportions of their corresponding sides must be congruent.

We know that all of AD is 15 and BD is 5, which leaves AB to be equal to 10.

Next, we set up the following proportion: 10/12 = 15/x because they are corresponding sides of similar triangles divided by eachother.

Cross multiply and you will get 10x = 12x15 (180)

next, divide both sides by 10 to isolate x

Answer:

So the solution is x = -0.57 and y = 30/7.

Step By Step Explanation:

To solve a system of linear equations, such as "x = 8 - 2y" and "3x + y = 6", we can use substitution or elimination method.

Using substitution method:

solve one equation for one variable

substitute the expression obtained in step 1 into the second equation

solve the equation obtained in step 2 to find the value of the variable that was solved for

substitute this value back into the first equation to find the value of the other variable.

x = 8 - 2y;

3x + y = 6;

solve for x in the first equation

x = 8 - 2y

substitute the value of x in the second equation

3(8-2y) + y = 6

solve the second equation obtained for y

24 - 6y + y = 6

25 - 6y = 6

-6y = -19

y = 19/6

substitute the value of y back in the first equation

x = 8 - 2(19/6) = 8 - (38/6) = 8 - (63/6) = 8 - (63/6) = 8 - 10.5 = -2.5

So the solution is x = -2.5 and y = 19/6

Alternatively, using elimination method:

Add or subtract one equation from the other to eliminate one of the variables.

Solve the resulting equation for the remaining variable.

Substitute this value into either of the original equations to find the value of the eliminated variable.

Multiply the first equation by -3

-3x = -24 + 6y;

Add the above equation to the second equation

-3x + y = 6

-24 + 6y + y = 6

-24 + 7y = 6

7y = 30

y = 30/7

substitute the value of y into the first equation

x = 8 - 2(30/7) = 8 - (60/7) = 8 - (60/7) = 8 - 8.57 = -0.57

So the solution is x = -0.57 and y = 30/7.

If there were only 5 coin tosses, the answer would be p5, where p= 0.6.

Now,

18 - 5 + 1 = 14 consecutive sequences of 5 flips contained in 18 flips. So it's tempting to say the answer is 14p5 ≈ 1.08, but it's also wrong. This is actually the number of expected 5-sticks, not the probability of at least one 5-stick. The problem is that since these sequences overlap, the events are not mutually exclusive, so we cannot sum them to get the overall probability. We have to subtract out all the possibilities of generating multiple 5 streaks, but calculating that probability is very complicated.

This post on stack swapping suggests an elegant approach that can be adapted to this problem. Let's define a sequence P(n). where P(n) is the probability of at least one consecutive heads after a total of n rollovers. So the answer of the question is P(18).

Clearly, P(0) = P(1) = P(2) = P(3) = P(4) = 0. This is because he can't get 5 heads in a row unless he flips the coin 5 times. P(5) is easy to compute, it only happens if all 5 flips are heads, so P(5) = p5 = 2433125 = 0.07776 .

Well, the length of the discontinuous part is n - 6, so the probability is

(1 −P(n−6)). The T,H,H,H,H,H part is the probability (1−p)p5 =(0,4)(0,6)5, and since these are independent events, the probability of THHHHH [not consecutive first letters] is (1−P( n −6))( 1−p) p5 .
