Pleaaassseee help me help my son!!! How do I get the sequence for the next 3 numbers 2,4,8,14,...?
The next three numbers in sequence are 22, 32 and 44
Solution:
Given sequence is:
2, 4, 8, 14, ...
We have to find the next 3 numbers in sequence
Let us understand the logic used in this sequence
[tex]First\ term = 1^2 -1+2 = 1 + 1 = 2\\\\Second\ term = 2^2 -2 + 2 = 4\\\\Third\ term = 3^2 - 3 + 2 = 9 - 1 = 8\\\\Fourth\ term = 4^2 -4 + 2 = 16-2 = 14[/tex]
Thus the formula used is:
[tex]a_n = n^2 - n +2[/tex]
Where, "n" is the location of term in sequence
To find the next three terms:
[tex]Fifth\ term = 5^2 - 5 + 2 = 25 - 3 = 22\\\\Sixth\ term = 6^2 - 6 + 2 = 36 - 4 = 32\\\\Seventh\ term = 7^2 -7 + 2 = 49 - 5 = 44[/tex]
Thus the next three numbers in sequence are 22, 32 and 44

45 = Length
A business owner pays $1,200 per month in rent and a total of $120 per hour in employee salary for each hour the store is open. On average, the store brings in $200 in net sales per hour.
Which equations can be solved to determine the break-even point if C(x) represents the cost function, R(x) represents the revenue function, and x the number of hours per month the store is open?
C(x) = 1,200+120x R(x) = 200x
C(x) = 1,200+120 R(x) = 200x
C(x) = 200x R(x) = 1,200+120x
C(x) = 200x R(x) = 1,200+120
Option A: [tex]C(x)=1,200+120 x R(x)=200 x[/tex] is the equation.
Explanation:
Let x represents the number of hours per month the store is open.
It is given that the the monthly rent(expense) = $1200
Also, the employee salary for each hour(expense) = $120x
Thus, the total expense C(x) is [tex]1200+120x[/tex]
It is also given that the income per hour(revenue) is $200x
Thus, the revenue function R(x) is [tex]200x[/tex]
The break - even point is given by
Total expense = Revenue
Thus, [tex]C(x)=1,200+120 x R(x)=200 x[/tex] is the equation.
Hence, Option A is the correct answer.

Which of the following expressions is equivalent to (12x^4-4x^3+7x+6)+(3x^2-4x+14)
An expression that is equivalent to [tex](12x^4-4x^3+7x+6)+(3x^2-4x+14)[/tex] include the following: D. [tex]12x^4-4x^3+3x^2+3x+20[/tex]
In Mathematics and Euclidean Geometry, the degree of a polynomial function is the highest power among each of its term.
The leading coefficient represents the coefficient of the leading term while the leading term is the term with the highest degree. Also, a constant polynomial is a polynomial that has only a constant term and no variable.
In this exercise and scenario, your are required to add the polynomial functions together.
First of all, we would rearrange the polynomial functions by collecting like terms and then add them together as follows;
[tex]12x^4-4x^3+3x^2-4x+7x+6+14\\\\12x^4-4x^3+3x^2+3x+20[/tex]
Complete Question:
Which of the following expressions is equivalent to [tex](12x^4-4x^3+7x+6)+(3x^2-4x+14)[/tex]?
A [tex]12x^4-x^3+3x+20[/tex]

C [tex]15x^6-4x^3+3x+20[/tex]
D [tex]12x^4-4x^3+3x^2+3x+20[/tex]
Final answer:
To find the equivalent expression, add like terms from both expressions, resulting in 12x⁴ - 4x³ + 3x² + 3x + 20.
Explanation:
To find the expression equivalent to (12x⁴-4x³+7x+6)+(3x²-4x+14), we simply add the like terms from both expressions.
Firstly, observe that there are no other terms with the same degree as 12x⁴ and -4x³, so they will remain as they are.
Next, add the coefficients of the x terms and the constants: 7x + (-4x) = 3x and 6 + 14 = 20.
However, there's a 3x² term in the second expression which doesn't have a matching term in the first expression, so it also remains unchanged.
Combining all these, the equivalent expression is 12x⁴ - 4x³ + 3x² + 3x + 20.

A graphic designer created a logo on 8 1/2 by 11 inch paper. In order to be placed on a business card, the logo needs to be 1 7/10 by 2 1/5. What is the scale factor of the dilation?
Answer:
0.2 (compression)
Step-by-step explanation:
Given
Length of paper = 11 inches,
Width of paper = 8 1/2 = 17/2 inches
Length of logo = 2 1/5 = 11/5 inches
Width of logo = 1 7/10 = 17/10 inches
Scale factor based on Length
=Length of Logo ÷ Length of paper
= 11/5 ÷ 11
= 0.2 (since it is less than 1, this is a compression)
(Sanity Check: Check width scale factor = length scale factor)
Scale factor based on width
=Width of Logo ÷ Width of paper
= 16/10 ÷ 17/2
= 0.2 (this is the same as the length scale factor so this checks out ok!)

Is 100 a solution of 10-0.035d > 4? Write a question that solving this problem could answer
Answer:
Therefore d = 100 is a solution of the given equation.
A question that solving this problem could answer is "what is the range of d"
d < 171.43
Step-by-step explanation:
i) the given equation is 10 - 0.035d > 4
ii) if d = 100 then 10 - (0.035[tex]\times[/tex] 100) = 10 - 3.5 = 6.5 > 4
Therefore d = 100 is a solution of the given equation.
A question that solving this problem could answer is "what is the range of d"
10 - 0.035d > 4
therefore -0.035d > 4 - 10
therefore -0.035d > -6
therefore 0.0035d < 6
therefore d < 6 / 0.035 [tex]\Rightarrow[/tex] d < 171.43
Final answer:
100 is a solution to the inequality 10 - 0.035d > 4 because, after substituting d with 100, the inequality 6.5 > 4 holds true.
Explanation:
To determine whether 100 is a solution of the inequality 10 - 0.035d > 4, we substitute d with 100 and check if the inequality holds true:
10 - 0.035(100) > 4
10 - 3.5 > 4
6.5 > 4
Since 6.5 is indeed greater than 4, we can confirm that 100 is a solution to the inequality.
A corresponding question this problem could answer might be: "If a part-time employee loses $0.035 from their savings for each day they work, after how many days will their savings be reduced to less than $4 if they initially had $10?" Solving the inequality would help find the maximum number of days the employee can work before their savings fall below $4.

The school marching band has a budget of up to $750 to cover 15 new uniforms and
competition fees that total $300. How much can they spend for one uniform?
a.
Write an inequality to represent this situation.
b.
Solve the inequality and describe what it means in the situation.
a. The inequality 15x+300≤750 represents the situation.
b. It means that the band can spend at most $30 on each uniform without exceeding the budget.
Step-by-step explanation:
Given,
Budget = $750
Competition fee = $300
Uniforms to make = 15
Let,
x be the amount for each uniform.
a. Write an inequality to represent this situation.
Uniforms to make * Cost per uniform + Competition ≤ Budget
15x+300 ≤ 750
The inequality 15x+300≤750 represents the situation.
b. Solve the inequality and describe what it means in the situation.
[tex]15x+300\leq 750\\15x+300-300\leq 750-300\\15x\leq 450[/tex]
Dividing both sides by 15
[tex]\frac{15x}{15}\leq \frac{450}{15}\\x\leq 30[/tex]
It means that the band can spend at most $30 on each uniform without exceeding the budget.

The inequality representing this situation is 15x + $300 <= $750. Solving for x gives x <= $30
The student is interested in determining how much the school marching band can spend on each new uniform given a specific budget constraint. To represent this situation, we need to establish an inequality.
Writing the inequality-
Let's denote the cost of one uniform as x. With 15 uniforms needed and competition fees totalling $300, the inequality that represents the budget situation is:
15x + $300 <= $750
Solving the inequality-
To solve for x, subtract $300 from both sides of the inequality:
15x <= $450
Next, divide both sides by 15:
x \<= $30
This means that they can spend at most $30 for each uniform. The inequality tells us the maximum spending cap for one uniform, ensuring the total cost for all uniforms plus competition fees does not exceed the available budget of $750.

The number of boys in the classroom is three more than the number of girls if there are 19 students how many are boys and how many are girls
Answer:
11 boys 8 girls
Step-by-step explanation:
There are 19 total students.
There are 3 more boys than girls
girls + 3 = boys ( because there are three more boys)
boys + girls = 19
You can substitute g +3 for b so:
2 girls +3 = 19
19 - 3 = 16
16/2 = girls
8 = girls
Once you find g just subtract the amount of girls from 19 to get the amount of boys.
19 kids - 8 girls = 11 boys
