What are the possible values of the missing term of the geometric sequence 6,....,13.5?
Answer:
THE ANSWER IS 1.5
Step-by-step explanation:
13.5 is the 3rd and last value. 6 is the first value.
The formula you need to use is an= 3r^n-1
13.5=3r^3-1
THE REASON YOU USE 3 IS BECAUSE IN TOTAL THERE ARE 3 TERMS AND WE ARE SOLVING FOR ONE MISSING TERM.
Now we bring 3 over to 13.5 to get r alone because we are solving for r
13.5/3 =r^2
Now we want to get rid of the square root. So we...
√13.5/3 =√r^2
The final answer is 1.5=2

f(x) 3x^2+x-3 g(x)=x^2-5x+1 find f(x)-g(x)
Answer:
2x² + 6x - 4
Step-by-step explanation:
f(x) - g(x)
= 3x² + x - 3 - (x² - 5x + 1) ← distribute
= 3x² + x - 3 - x² + 5x - 1 ← collect like terms
= 2x² + 6x - 4
Answer:
f(x) - g(x) = 2x² - 4x - 2
Step-by-step explanation:
f(x) = 3x² + x - 3
g(x) = x² - 5x + 1
f(x) - g(x)
3x² + x - 3 - x² - 5x + 1
3x² - x² - 5x + x - 3 + 1
= 2x² - 4x - 2
f(x) - g(x) = 2x² - 4x - 2

Step-by-step explanation:
An airliner is 9.34 feet wide. The airline wants to install 5 seats in each row. The seats are each 1.46 feet wide. Rounded to the nearest tenth, about how much space would be left for the aisle?
About 2.0 feet space will be left for aisle.
Step-by-step explanation:
Width of airliner = 9.34 feet
Width on one seat = 1.46 feet
Seats to install = 5
Width of 5 seats = 5*1.46 = 7.3 feet
Space left for aisle = Width of airliner - width of 5 seats
[tex]Space\ left\ for\ aisle=9.34-7.3\\Space\ left\ for\ aisle=2.04\ feet[/tex]
Rounding off to nearest 10th
Space left for aisle = 2.0 feet
About 2.0 feet space will be left for aisle.

brainly.com/question/10435836brainly.com/question/10541435#LearnwithBrainly
To find the space left for the aisle, we first calculate the total seat width (5 seats × 1.46 feet/seat) and subtract it from the airliner width (9.34 feet), resulting in 2.0 feet of space for the aisle when rounded to the nearest tenth.
Explanation:To calculate the available space for the aisle in an airliner, we first determine the total width consumed by the seats. Since each seat is 1.46 feet wide and there are 5 seats in a row, we multiply the width of one seat by the number of seats:
1.46 feet/seat × 5 seats = 7.3 feet
Next, we subtract the total width of the seats from the total width of the airliner to find the space left for the aisle:
9.34 feet (total width) - 7.3 feet (width of seats) = 2.04 feet
Therefore, rounded to the nearest tenth, there would be approximately 2.0 feet of space left for the aisle.
is this a function ?
Answer:
No
Step-by-step explanation:
For the relation to be a function
Each value of x from the domain ( values on left ) must map to exactly one unique value of y in the range ( values on the right )
Here x = 0 → 0 and 1 ( that is 2 values from the range )
Thus this does not represent a function
use the rational exponent property to write an equivalent expression for
[tex] \sqrt[5]{n ^{4} } + 3 - 12[/tex]
Using the rational exponent property, an equivalent expression for[tex]\(x^{3/4}\[/tex] can be written as[tex]\(\sqrt[4]{x^3}\).[/tex]
Explanation:The rational exponent property states that for any real number a and positive integer[tex]\(n\), \(a^{m/n} = \sqrt[n]{a^m}\)[/tex] . Applying this property to the given expression[tex]\(x^{3/4}\[/tex] ), where (m = 3) and (n = 4), we can rewrite it as [tex]\(\sqrt[4]{x^3}\)[/tex] . This is derived by taking the fourth root of [tex]\(x^3\),[/tex] which is equivalent to raising [tex]\(x^3\)[/tex] to the power of[tex]\(1/4\).[/tex]
To further understand this, consider the original expression [tex]\(x^{3/4}\).[/tex] This represents the fourth root of [tex]\(x^3\)[/tex] , as the numerator 3 indicates the power to which x is raised, and the denominator 4 indicates the root. Expressing it as [tex]\(\sqrt[4]{x^3}\)[/tex] provides a clearer representation of the same mathematical concept, emphasizing the fourth root of [tex]\(x^3\).[/tex]
In mathematical notation, the rational exponent property is a useful tool for simplifying expressions involving fractional exponents. It allows us to transform expressions between radical form and exponent form, providing flexibility in mathematical manipulations and aiding in the understanding of the underlying concepts.
Marty ordered three extremely accurate and scientific water-balloon launchers from a mail order catalog (one for himself and two for his friends). The total price including shipping charges was $50. If the total shipping cost was $5, how much did each launcher cost?
Answer:
The price of each launcher is $ 15 .
Step-by-step explanation:
Given as :
The total price of three water balloon launchers including shipping charges = $50
The cost of the three shipping = $ 5
So, The price of water balloon launchers excluding shipping charges = $50-$5 = $ 45
Now,
∵ The price of 3 balloon launcher = $45
∴, The price of 1 balloon launcher = [tex]\frac{45}{3}[/tex] = $15
Hence The price of each launcher is $ 15 . Answer

At the market, 8 apples cost $4dollar. How much do 9 apples cost?
Answer: $4.50 for 9 apples
Step-by-step explanation: To find out how much it is for 1 apple, we need to find the unit price of 1 apple which is the cost per apple.
Since we know that it costs $4 for 8 apples, to find the cost for 1 apple, we need to divide 8 into $4 or 4 divided by 8 which is 0.5 of 50 cents per apple.
Since we know that it costs 50 cents per apple, to find the cost for 9 apples, we will need to multiply .50 by 9.
(.50) (9) = 4.50
Therefore, it will cost $4.50 for 9 apples.

Final answer:
The question pertains to writing an equation for a mathematics-related scenario, emphasizing the importance of understanding equations as expressions of concepts rather than just tools for calculation.
Explanation:
The subject of this question appears to revolve around forming an equation that could pertain to a mathematics problem. The use of mathematical equations to convey concepts is crucial; they aren't just mechanisms for inserting and churning numbers, but they are sentences that express concepts precisely and purposefully. Writing out such equations in both words and symbols ensures comprehension of the underlying reasoning.
Moreover, when teaching mathematics, it's beneficial to allow students to create their own formulas. This practice not only solidifies the understanding of concepts but also emphasizes that the symbols used in equations are arbitrary and that what matters is the concept they represent.
Remembering the correct order of operations is essential, which can be recalled with the mnemonic 'Please Excuse My Dear Aunt Sally.' Also, an iterative relation often used in advanced mathematics is not an equation per se, but rather a set of instructions for approximating a solution. This iterative process requires a different approach compared to straightforward equation solving.
The expression x2 - 36y2 is equivalent to
Answer:
(x + 6y)(x - 6y)
Step-by-step explanation:
The expression x² - 36y² can be factored.
Since the expression is a difference (subtraction) between two numbers that are square (x² = x*x and 36y² = 6y*6y), the factoring can be done as a "difference of squares".
The rules is generalized as: [tex]x^{2} - y^{2} = (x - y)(x+y)[/tex]
To factor x² - 36y², take each square roots for each of the numbers and add and subtract between them.
x² - 36y²
= (√x² + √36y²)(√x² - √36y²)
= (x + 6y)(x - 6y)
The price of a toaster increase 10% to $40. What is the original price of the toaster before the increase?
Answer:
36.36
Step-by-step explanation:
We can express 10% as a decimal by multiplying it by (1/100), resulting in 0.1. Therefore, adding 0.1 of the original price, or x, to the price will result in 40, so x+0.1*x=40
= 1.1x
Dividing both sides by 1.1, we get that x, or the original price, is $36.36 (approximately).

The equation of the function represented by the table is y = 5 x + 2
Step-by-step explanation:
The equation of the linear function in the slope-intercept form is
y = m x + b, where
m is the slope of the lineThe formula of the slope is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] , where [tex](x_{1},y_{1})[/tex] and [tex](x_{1},y_{1})[/tex] are any two points lie on the lineb is the y-intercept, means the line intersects the y-axis at point (0 , b)The table:
→ x : 0 : 1 : 2 : 3 : 4
→ y : 2 : 7 : 12 : 17 : 22
Let us chose any two points from the table to calculate the slope
∵ Points (1 , 7) and (2 , 12) lie on the line
∴ [tex]x_{1}[/tex] = 1 and [tex]x_{2}[/tex] = 2
∴ [tex]y_{1}[/tex] = 7 and [tex]y_{2}[/tex] = 12
- Substitute these values in the formula of the slope
∵ [tex]m=\frac{12-7}{2-1}=\frac{5}{1}[/tex]
∴ m = 5
Substitute the value of m in the form of the equation
∵ y = m x + b
∴ y = 5 x + b
∵ The line intersects the y-axis at point (0 , b)
∵ From the table point (0 , 2) lies on the line
∴ b = 2
∴ y = 5 x + 2
The equation of the function represented by the table is y = 5 x + 2

There are 450 children that attend a high school. Of those students. 23%
are in the marching band. How many students are not in the marching
band?
Answer:
The number of students not in the marching band is 346.5
Step-by-step explanation:
Given as :
The total number of children that attend a high school = 450
The percentage of students in the marching band = 23 %
Let The number of students not in the marching band = x
Now ,
∵ The percentage of students in the marching band = 23 %
∴ The percentage of students not in the marching band = 100 % - 23 % = 77 %
So, The number of students not in the marching band = 77 % of the total number of students in the school
I.e The number of students not in the marching band = 77 % × 450
Or , The number of students not in the marching band = [tex]\frac{77}{100}[/tex] × 450
∴ The number of students not in the marching band = 346.5
And The number of students in the marching band = 450 - 346.5 = 103.5
Hence The number of students not in the marching band is 346.5 Answer
Write the quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4.
The quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4, is: [tex]\[\bo{4x^2 - 36x + 80 = 0}\][/tex]
Step 1
To write a quadratic equation with given roots and a specified leading coefficient, we can use the fact that if p and q are the roots of a quadratic equation, the equation can be written as:
[tex]\[a(x - p)(x - q) = 0\][/tex]
where a is the leading coefficient.
Given roots: [tex]\( p = 4 \)[/tex] and [tex]\( q = 5 \)[/tex]
Leading coefficient: [tex]\( a = 4 \)[/tex]
Step 2
Let's substitute these values into the equation:
[tex]\[4(x - 4)(x - 5) = 0\][/tex]
Now, we need to expand this equation. First, expand the product [tex]\((x - 4)(x - 5)\):[/tex]
[tex]\[(x - 4)(x - 5) = x^2 - 5x - 4x + 20 = x^2 - 9x + 20\][/tex]
Step 3
Next, multiply this expression by the leading coefficient [tex]\( 4 \)[/tex]:
[tex]\[4(x^2 - 9x + 20) = 4x^2 - 36x + 80\][/tex]
Thus, the quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4, is:
[tex]\[\bo{4x^2 - 36x + 80 = 0}\][/tex]

If you buy a home and make a relatively small down payment, what happens to the monthly payments and total payment for you loan?
Answer:
Both monthly payment and total payment will increase.
Step-by-step explanation:
If I buy a home and make a relatively small down payment, then the due payment will be more.
If I pay for my home through a bank and I fix the number of installments to pay back the due amount after down payment (say, monthly installment for 5 years), then the amount of installment payment will definitely increase if my down payment is less.
Again, if the down payment is less, the remaining amount to pay back will rise and the bank calculates interest on the remaining amount to pay. Therefore, the amount of interest will rise in value and finally the total payment after interest for my loan will increase. (Answer)

Answer:
y = -2x - 1
Step-by-step explanation:
Formula is y = mx + b
m = slope
slope = change in y/change in x = (-1 - 3) / (0 - -2) = -4/2 = -2
So equation is now y = -2x + b
To find b, substitute any value from the table into the equation. Let's use (-2,3)
y = -2x + b
3 = -2(-2) + b
3 = 4 + b
-1 = b
So equation is y = -2x - 1
Answer:
C. This can be found by looking at when x=0. If y=-1, then that means that the y intercept is -1, so plug in 1 to either one of the middle two equations and see if it works.
