Answer:
4, 12, 36, 108 is set of geometric sequence.
Step-by-step explanation:
Given : geometric sequence.
To find : Which set of numbers is a geometric sequence.
Solution : We have given geometric sequence.
In a Geometric Sequence each term is found by multiplying the previous term by a constant.
Like : {a, ar, ar², ar³, ... }, where , a = first term , r = common ration .
We can see sequence 4, 12, 36, 108 in form of 4 , 4*3 , 4 (3)² , 4( 3)³.
Here, common ration is 3.
Therefore, 4, 12, 36, 108 is set of geometric sequence.
At the beginning of the year, Adrian's savings account balance was $28. Each week, he deposits another $15 into that account, and he doesn't spend any of his savings.
Is his savings account balance proportional to the number of weeks since the start of the year?
Answer:
The given condition is not proportional.
Step-by-step explanation:
At the beginning of the year, Adrian's savings account balance was $28.
Let Adrian invests for 'x' weeks.
So, total amount will becomes :
[tex]28+15x[/tex]
Since 4 weeks = 1 month, it will represent a linear equation only.
Linear functions have a constant rate of change and describe a straight line on a graph. So, this is not proportional.
The given equation is in the form y = mx + b, so its linear. For the equation to be proportional, it should be in the form of y = kx.

Yi and Sue play a game. They start with the number $42000$. Yi divides by a prime number, then passes the quotient to Sue. Then Sue divides this quotient by a prime number and passes the result back to Yi, and they continue taking turns in this way.
For example, Yi could start by dividing $42000$ by $3$. In this case, he would pass Sue the number $14000$. Then Sue could divide by $7$ and pass Yi the number $2000$, and so on.
The players are not allowed to produce a quotient that isn't an integer. Eventually, someone is forced to produce a quotient of $1$, and that player loses. For example, if a player receives the number $3$, then the only prime number (s)he can possibly divide by is $3$, and this forces that player to lose.
Who must win this game, and why?
Answer:
The first person starting will always lose.
Step-by-step explanation:
First, I will the prime factorization of 42000. After finding the prime factorization of 42000, I will count the number of primes in the prime factorization. After that, we will find which round the person will lose.
Prime Factorization of 42000: 2*2*2*2*3*5*5*5*7
Number of Primes in List: 9
The person losing: The person on the 9th turn will lose.
The person on the 9th turn is Yi. Therefore, no matter how Yi or Sue keeps mixing the order of the numbers, Yi will always lose.

What is rounding up numbers?
There are basically two rules while rounding up numbers
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
Non-zero digits are always significant
Zeros between non-zero digits are always significant
Leading zeros are never significant
Trailing zeros are only significant if the number contains a decimal point
Given data ,
Let the number be N
The value of N = 98984
Now , the number N has 5 significant numbers
So , the next higher number where N can be rounded is

Rewrite as a simplified fraction 1.1 3 =?
The requried 1.1 3 can be written as a simplified fraction of 44/333.
What is the fraction?A fraction is a mathematical concept that can be used to express a portion of a whole or a number that can be written as the ratio of two integers. In a fraction, the top number is referred to as the numerator, while the bottom number is referred to as the denominator.
Here,
To rewrite 1.1 3 as a simplified fraction, we can first recognize that the repeating decimal can be represented as a fraction using a geometric series.
Let x = 0.133. Then, we can multiply both sides of this equation by 1000 to obtain
1000x = 133.333...
Next, we can subtract x from 1000x to obtain
999x = 133.333... - 0.133...
Simplifying the right side gives
999x = 133.2
Finally, dividing both sides by 999 gives
x = 133.2 / 999 = 44 / 333
Therefore, 1.1 3 can be written as a simplified fraction of 44/333.

the equation of g(x) after stretching the graph of f(x) vertically by a factor of 2. Therefore, the equation of g(x) is g(x) = 4(3)^x+1 + 8.
To stretch the graph of (f(x)) vertically by a factor of 2 to form the graph of ( g(x)), we need to multiply the entire function (f(x)) by 2.
Given:
[tex]\[ f(x) = 2(3)^{x+1} + 4 \][/tex]
To stretch the graph vertically by a factor of 2, we multiply the function by 2:
[tex]\[ g(x) = 2 \cdot f(x) \][/tex]
Substitute the expression for [tex]\( f(x) \):[/tex]
[tex]\[ g(x) = 2 \cdot [2(3)^{x+1} + 4] \][/tex]
Now, distribute the 2 inside the brackets:

Kevin is 3 times as old as Daniel, 4 years ago, Kevin was 5 times as old as Daniel. How old is Kevin
By using equations to represent the relationship between Kevin and Daniel's ages, we can determine that Kevin is 24 years old.
Kevin is 3 times as old as Daniel. Let's denote Kevin's age as K and Daniel's age as D. From the information given, we can form two equations:
K = 3D
K - 4 = 5(D - 4)
3D - 4= 5D -20
16 = 2D
D = 8
K = 24
Solving these equations simultaneously gives the age of Kevin, therefore, Kevin is 24 years old.

2(b+3c) equivalent expressions
Options:
3(b+2c)
(b+3c) +(b+3c)
None of the above
The correct answer to the given expression 2(b+3c) is 'None of the above' as none of the provided options represent an equivalent expression after the application of distributive property.
Explanation:The expression 2(b+3c) cannot be transformed into any of the given options directly. If we use distributive property, we expand 2(b+3c) to get 2b + 6c, which is equivalent to the original expression.
The options provided, such as 3(b+2c), (b+3c) +(b+3c), or 'None of the above', do not simplify or represent an equivalent expression to 2(b+3c). The correct answer is 'None of the above'. It's important to note that the commutative property of addition, A+B = B+A, and the associative property, (A+B) + C = A +(B+C), suggest that we can regroup or reorder terms in an addition expression without changing its value. However, none of these properties help in finding an equivalent expression among the given options for 2(b+3c).
six is greater than or equal to the quotient of a number y and 2.5
The statement 'six is greater than or equal to the quotient of a number y and 2.5,' can be converted into the inequality 6 >= y/2.5. Solving for y by multiplying both sides by 2.5 gives y <= 15. Therefore, any number y that is 15 or less will satisfy this inequality.
Explanation:The question provided, 'six is greater than or equal to the quotient of a number y and 2.5,' requires manipulation of an inequality in mathematics to find the potential values of y. To represent this in mathematical terms, one could write the inequality as 6 ≥ y/2.5. From here, it is a simple matter of isolating y by multiplying both sides of the inequality by 2.5, which results in y ≤ 15. Therefore, any number y that is less than or equal to 15 satisfies the inequality.
