What is a geometric sequence?There are three parameters which differentiate between which geometric sequence we're talking about.
The first parameter is the initial value of the sequence.
The second parameter is the quantity by which we multiply previous term to get the next term.
The third parameter is the length of the sequence. It can be finite or infinite.
Suppose the initial term of a geometric sequence is 'a'
and the term by which we multiply the previous term to get the next term is 'r' (also called the common ratio)
Then the sequence would look like
[tex]a, \: ar, \: ar^2, \: ar^3, \: \cdots[/tex]
(till the terms to which it is defined)
If the initial term is 'a', then the geometric sequence with common ratio = 2 would look like:
[tex]a, \: a(2), \: a(2)^2, \: a(2)^3, \: \cdots\\\\a, \: a(2), \: a(4), \: a(8), \: \cdots[/tex]
Checking all the options to see which one has got common ratio 2:
A. 14, 16, 18, 20, ...Initial term a = 14,
The geometric sequence with a = 14, and r = 2 would be:

The sequence 14, 16, 18, 20, ... doesn't match with it, so its not correct option.
B. 64, 32, 16, 8, ...Initial term a = 64,
The geometric sequence with a = 14, and r = 2 would be:
[tex]64, 64(2), 64(4), 64(8), \cdots\\\\64, 128, 256, 512, \cdots\\[/tex]
The sequence 64, 32, 16, 8, ... doesn't match with it, so its not correct option.
C. 14, 28, 56, 112, ...Initial term a = 64,
The geometric sequence with a = 14, and r = 2 would be:
[tex]14, 14(2), 14(4), 56(8), \cdots\\\\14, 28, 56, 112, \cdots\\[/tex]
The sequence 14, 28, 56, 112, ... matches with it, so its correct option.
D. 87, 85, 83, 81, ...Initial term a = 87,
The geometric sequence with a = 87, and r = 2 would be:
[tex]87, 87(2), 87(4), 87(8), \cdots\\\\87, 174, 348, 696, \cdots\\[/tex]

The length of a rectangle is 5 more than 3 times its width. The perimeter of the rectangle is 58 in. What is the length of the rectangle?
A. 23 in.
B. 29 in.
C. 32 in.
D. 35 in.
Answer:
The correct answer is option A. 23 in
Step-by-step explanation:
It us given that, the length of a rectangle is 5 more than 3 times its width. The perimeter of the rectangle is 58 in.
To find the length of rectangle
Let 'x' be the width of rectangle.
Length = 3x + 5
Perimeter of rectangle = 2(length + width)
58 = 2(3x + 5 + x)
58 = 2(4x + 5)
29 = 4x + 5
4x = 29 - 5
4x = 24
x = 24/4 = 6
Therefore length of rectangle = 3x + 5
= 3*6 + 5 = 23 in
The correct answer is option A. 23 in

If tan x° = 11 divided by r and cos x° = r divided by s, what is the value of sin x°?
sin x° = s divided by 11
sin x° = 11 divided by s
sin x° = 11r
sin x° = 11s
Answer:
sin(x°) = 11/s
Step-by-step explanation:
The tangent is the ratio of sine to cosine, so ...
tan(x°) = sin(x°)/cos(x°)
Multiplying by cos(x°) gives ...
sin(x°) = cos(x°)·tan(x°) = (r/s)·(11/r)
sin(x°) = 11/s
Answer:
sin x° = 11 divided by s
Step-by-step explanation:
Given,
tan x° = 11 divided by r
[tex]\implies tan x^{\circ}=\frac{11}{r}[/tex]
Also, cos x° = r divided by s
[tex]\implies cos x^{\circ}=\frac{r}{s}[/tex]
We know that,
[tex]\frac{sinx^{\circ}}{cos x^{\circ}}=tan x^{\circ}[/tex]
[tex]\implies sinx^{\circ}= tan x^{\circ}\times cos x^{\circ}[/tex] ( by cross multiplication )
By substituting the values,
[tex]sin x^{\circ}=\frac{11}{r}\times \frac{r}{s}=\frac{11r}{rs}=\frac{11}{s}[/tex]
⇒ sin x° = 11 divided by s

Answer:
The maximum height of the marshmallow is 49 feet.
Step-by-step explanation:
The vertex form of a parabola is
[tex]y=a(x-h)^2+k[/tex] .... (1)
Where, (h,k) is vertex of the parabola is a is constant.
The given function is
[tex]h=-16(t-14)^2+49[/tex] ..... (2)
Where, h is height of the marshmallow (in feet) and t is the time (in seconds) after he throws the marshmallow.
From equation (1) and (2), we get
[tex]a=-16,h=14,k=49[/tex]
The value of a is -16, which is less than 0. So, the given function is a downward parabola.
The vertex of a downward parabola is the point of maxima.
The value of h is 14 and the value of k is 49. So, the vertex of the parabola is (14,49). It means the maximum height of the marshmallow is 49 feet in 14 seconds.
Therefore the maximum height of the marshmallow is 49 feet.

A gas tank can hold 12 gallons of gas. The equation p(g) = 3.5g gives the amount of money it costs when filling the tank with gas. What is the range for this situation?
The range for this situation represents all possible values of the cost of filling the gas tank in dollars.
Explanation:The range for this situation represents the set of all possible outputs of the function, which in this case is the cost of filling the gas tank.
Since the equation given is p(g) = 3.5g, the range would be all possible values of p, the cost of filling the gas tank.
The range would depend on the values of g, the amount of gas in gallons, that you input into the equation.
For example, if you fill the tank with 1 gallon of gas, the cost would be p(1) = 3.5 * 1 = $3.50.
If you fill the tank with 3 gallons of gas, the cost would be p(3) = 3.5 * 3 = $10.50.
Therefore, the range for this situation would be all values of p, the cost, that can be obtained by inputting different values of g, the amount of gas in gallons, into the equation p(g) = 3.5g.
The range for this situation is from $0 (empty tank) to $42 (full tank). The cost can be any value in this range depending on the number of gallons pumped into the tank.
In this context, the function [tex]\( p(g) = 3.5g \)[/tex] represents the cost p of filling the gas tank with g gallons of gas. The range of the function is the set of all possible values for the cost.
Since the cost is directly proportional to the number of gallons, we can evaluate the function for the minimum and maximum values of g . The minimum value of g is 0 gallons (empty tank), and the maximum value is 12 gallons (full tank).
1. For g = 0 , [tex]\( p(0) = 3.5 \times 0 = 0 \)[/tex]. So, the minimum cost is $0.
2. For g = 12 , [tex]\( p(12) = 3.5 \times 12 = 42 \)[/tex]. So, the maximum cost is $42.
Therefore, the range for this situation is from $0 (empty tank) to $42 (full tank). The cost can be any value in this range depending on the number of gallons pumped into the tank.

Mark and Julio are selling flower bulbs for a school fundraiser. Customers can buy bags of windflower bulbs and packages of crocus bulbs. Mark sold 2 bags of windflower bulbs and 5 packages of crocus bulbs for a total of $105. Julio sold 9 bags of windflower bulbs and 5 packages of crocus bulbs for a total of $164.50. Find the cost each of one bag of windflower bulbs and one package of crocus bulbs. Solve having substitution method.
To find the cost of one bag of windflower bulbs and one package of crocus bulbs, we can use the substitution method. By setting up a system of equations and solving for the variables, we find that the cost of one bag of windflower bulbs is $45 and the cost of one package of crocus bulbs is $7.50.
Explanation:To find the cost of one bag of windflower bulbs and one package of crocus bulbs, we can set up a system of equations. Let's use the substitution method.
Let x represent the cost of one bag of windflower bulbs and let y represent the cost of one package of crocus bulbs.
We can set up two equations:
2x + 5y = 105
9x + 5y = 164.50
From the first equation, we can rewrite it as: 2x = 105 - 5y. We can substitute this expression for 2x in the second equation:
9(105 - 5y) + 5y = 164.50
Solving for y, we get y = 7.50. Substituting this value back into the first equation, we can solve for x: 2x + 5(7.50) = 105. Solving for x, we get x = 45.
Therefore, the cost of one bag of windflower bulbs is $45 and the cost of one package of crocus bulbs is $7.50.

Follow below steps:
Mark and Julio are selling flower bulbs for a school fundraiser. To find the cost of one bag of windflower bulbs and one package of crocus bulbs, we set up two equations based on the information given, and then solve them using the substitution method.
Let x be the cost of one bag of windflower bulbs and y be the cost of one package of crocus bulbs. According to Mark's sales, the equation is:
2x + 5y = 105 ...(1)
According to Julio's sales, the equation is:
9x + 5y = 164.50 ...(2)
To use the substitution method, we first isolate y in equation (1):
y = (105 - 2x) / 5 ...(3)
Next, we substitute equation (3) into equation (2):
9x + 5((105 - 2x) / 5) = 164.50
9x + 105 - 2x = 164.50
7x = 59.50
x = 8.50
Now that we have the value for x, we can use it to find y by substituting x back into equation (3):
y = (105 - 2(8.50)) / 5
y = (105 - 17) / 5
y = 88 / 5
y = 17.60
Therefore, the cost of one bag of windflower bulbs is $8.50 and the cost of one package of crocus bulbs is $17.60.

Answer:
irrational
Step-by-step explanation:
Pi is irrational.
-1 is rational.
Their sum is irrational.
_____
In general, the sum of a rational number and an irrational number is irrational.
The number 'pi' is an irrational number. When we subtract 1 from 'pi', we still obtain an irrational number, therefore 'pi-1' is irrational.
Explanation:The number pi is a well-known irrational number. An irrational number cannot be expressed as a ratio of two integers, and its decimal expansion never ends or repeats. When we subtract 1 from pi, we get another number. Since we are creating a new number by subtracting an integer from an irrational number, that number remains irrational. Therefore, pi-1 is also an irrational number.

The equation used to solve for x in the given diagram is 7x + 11x = 90, representing the total sum as 90 degrees.
In the diagram, you have an angle formed by two given lines. To find the value of x, you can use the fact that the total sum is 90 degrees.
1. The first angle of the diagram is labeled as 7x.
2. The second angle of the diagram is labeled as 11x.
So, the equation for the sum of these angles should equal 90 degrees:
7x + 11x = 90
Now, you can simplify the equation:
18x = 90
To isolate x, divide both sides by 18:
18x / 18 = 90/ 18
x = 5
So, the equation used to solve for x is indeed 7x + 11x = 90, which simplifies to 18x = 90 when considering the angles around the point.

What are the zeros of the following quadratic equation: y = 6x^2 - 17x - 3 Step by Step
Answer:
x = 3, x = -1/6 are the zeros
Step-by-step explanation:
I find graphing the equation using a graphing calculator to be about the fastest way to find the zeros.
__
For this equation, you can look for factors of 6·(-3) = -18 that have a sum of -17. Those are -18 and +1, so the factorization of the equation is ...
y = (1/6)(6x -18)(6x +1) = (x -3)(6x +1)
The roots are the values of x that make the factors be zero, so x=3 and x=-1/6.
__
You can also use the quadratic formula to find the zeros. That tells you the solution to ...
ax² +bx +c = 0
is
x = (-b ±√(b²-4ac))/(2a)
Comparing your equation to the standard form, you can identify the coefficients as ...
a = 6, b = -17, c = -3
so the zeros are ...
x = (-(-17) ±√((-17)² -4(6)(-3)))/(2(6))
x = (17 ±√369)/12 = (17 ±19)/12 = {-2, 36}/12 = {-1/6, 3}
The zeros are x = -1/6 and x = 3.
To find zeros of a quadratic equation, you use the quadratic formula. Applying this formula to the equation y = 6x^2 - 17x - 3 yields two solutions, representing the two points where the function intersects the x-axis.
Explanation:The subject of this question concerns finding the zeros of a given quadratic equation, y = 6x^2 - 17x - 3. Zeros are the x-values that make the equation equal to zero or to point where the function intersects the x-axis.
To find the zeros, we'll use the quadratic formula, which is derived from an equation of the form ax² + bx + c = 0: x = [ -b ± sqrt(b^2 - 4ac) ] / (2a).
Applying the quadratic formula to your equation, with a = 6, b = -17, and c = -3, we get the two solutions, which are the zeros of the equation: x = [ 17 ± sqrt((-17)^2 - 4*6*-3) ] / (2*6). Computing this, we get two solutions, or two zeros, which are the points where your function y = 6x^2 - 17x -3 crosses the x-axis.

There are 32 teams participating in a single-elimination soccer tournament, in which only the winning teams from each round progress to the next
round of the tournament
The graph shows the number of teams, fx) that are still in the tournament after x rounds have been completed
f(x)
Answer:
D = {0 , 1 , 2 , 3 , 4 , 5} and R = {1 , 2 , 4 , 8 , 16 , 32} ⇒ answer D
Step-by-step explanation:
* Lets talk about the domain and the range of a function
- The domain is the input values
- The range is the output values
- f(x) = y, x is the input then x is the domain of the function and y is the
output then y is the range of the function
- Example:
# If x = {2 , 3 , 5) and f(x) = 2x
- The input is x to find f(x) substitute the values of x in f(x)
- f(2) = 2(2) = 4 , f(3) = 2(3) = 6 , f(5) = 2(5) = 10
- The output is f(x) = {4 , 6 , 10}
- From all steps above the domain of f(x) is {2 , 3 , 5) and the range
is {4 , 6 , 10}
* Lets solve the problem
- There are 32 teams participating in a single-elimination soccer
tournament
- x is the number of rounds
- f(x) is the number of teams
- only the winning teams from each round progress to the next
round of the tournament
* Lets look to the graph and find the domain and the range
- The domain the the values of x and the range is the values of f(x)
∵ At x = 0 then f(0) = 32 ⇒ 32 teams inter the 1st round
∵ At x = 1 then f(1) = 16 ⇒ 16 teams inter the 2nd round
∵ At x = 2 then f(2) = 8 ⇒ 8 teams inter the 3rd round
∵ At x = 3 then f(3) = 4 ⇒ 4 teams inter the 4th round
∵ At x = 4 then f(4) = 2 ⇒ 2 teams inter the 5th round
∵ At x = 5 then f(5) = 1 ⇒ 1 team in win
- From all above:
∴ The domain is {0 , 1 , 2 , 3 , 4 , 5} and the range is {1 , 2 , 4 , 8 , 16 , 32}
* D = {0 , 1 , 2 , 3 , 4 , 5} and R = {1 , 2 , 4 , 8 , 16 , 32}

a number d is decreased by 5 and then doubled
Answer:
(d-5)x2
Step-by-step explanation:
you said a number d is subtracted by 5 then doubled so lets make an example. d=6
(6-5)x2
(6-5)=6-5=1
(1)x2=1x2=2
If a number d is decreased by 5 and then doubled, then we can represent that event with an algebraic expression as:
[tex]2\times (d-5)[/tex]
Given that:The considered number is decreased by 5Then the result is doubled.Formation of equation:The number d decreased by 5 is written as: [tex]d - 5[/tex]
When we double a thing, we multiply by 2.
Thus we have the algebraic form of given condition as:
[tex]2\times(d-5)[/tex]
