The second series does converge. As the sequence continues, the numerator will stay 1 and the denominator will continue to increase. This means the overall fraction gets smaller and smaller, approaching 0. Thus the sum will approach a finite number.
The third series does not converge. As the exponents get larger and larger, the answers will swing to larger positives and larger negatives each time. As the sum goes on, the absolute value of it will get larger and the sign will switch.
The fourth series does not converge. As 2 gets raised to a higher and higher exponent, the product of it and 1/5 will be a larger and larger number. It will approach infinity, not a finite number.

1. J. Cole is a successful Hip-Hop recording artist. He has a record contract that pays him $20,000 a month plus an additional $12 for each album that he sells. Last month he earned $24,800. Write an equation to express the money J. Cole earned last month. Let "x" represent the number of albums.
2. How many albums did J. Cole sell last month?
Answers
Payment per album = $12
Total earned last month = $24,800
Part (a): Expression for money earned last month
Let x be number of albums last month. Then,
Total earning = Fixed payment + Variable payment
That is,
24,800 = 20,000 + 12*x
24,800 = 20,000 + 12x
Part (b): Number of albums last month
This involves solving for x in the expression derived in part (a) above.
24,800 = 20,000 + 12x
24,800 - 20,000 = 12
12x = 4,800
x = 4,800/12 = 400 albums

Write two operations in order that you would use to solve the equation 3x - 2=7 then solve the equation

3x = 7 + 2
3x = 9
x = 9/3
x = 3
You first subtract 2 from both sides, so 2-2=0 & 7-2=5
3x=5
Then you divide 3 from both sides to get “X” alone, 3x/3= 1x (but the the one is invisible so it equal “X”) and then 5/3= 1.66666..

Answers
Answer:
2 8 -8 2
Step-by-step explanation:
The correct answer is [tex]-\frac{1}{2}x + 3 = -x + 7$ is $x = 8[/tex].
To solve the equation [tex]-\frac{1}{2}x + 3 = -x + 7[/tex], we can follow these steps:
Step 1: Combine like terms on both sides of the equation.
[tex]-\frac{1}{2}x + 3 = -x + 7[/tex]
[tex]\frac{1}{2}x - 3 = x - 7[/tex]
Step 2: Subtract [tex]x[/tex] from both sides to isolate the terms with [tex]x[/tex].
[tex]\frac{1}{2}x - 3 - x = -7[/tex]
[tex]-\frac{1}{2}x - 3 = -7[/tex]
Step 3: Add 3 to both sides to isolate the term with [tex]x[/tex].
[tex]-\frac{1}{2}x = -4[/tex]
Step 4: Multiply both sides by [tex]-2[/tex] to solve for[tex]x[/tex].
[tex]-2 \left(-\frac{1}{2}x\right) = -2(-4)[/tex]
[tex]x = 8[/tex]
Therefore, the solution to the equation [tex]-\frac{1}{2}x + 3 = -x + 7$ is $x = 8[/tex]

Which graph shows a proportional relationship? help!!
Answers
Which example best represents balanced forces
Answers
The forces are equal and opposite, the book remains at rest, representing a state of balanced forces.
Balanced forces occur when the net force acting on an object is zero, meaning that the forces are equal in magnitude and opposite in direction. As a result, the object remains in a state of equilibrium and does not accelerate.
One example that best represents balanced forces is:
A book resting on a table.
When a book is placed on a table, it doesn't move because the force of gravity pulling it down (its weight) is balanced by the normal force exerted by the table, pushing the book upward.

Graph the line that represents the proportional relationship.
Answers
In this activity, you'll calculate a probability and use it to predict the result of repeating a simple chance-based trial many times.
You are in charge of the casino night game area at a fundraising event. In one of the games, called Odd Odds, the player rolls two six-sided dice. The player gets points if the product of the two numbers rolled is odd. So, success in the game depends on the chances of getting an odd number for the result.
1)Find the number of outcomes in the sample space, n(S), of the trial of this game.
2)List and count all the outcomes for event E, in which the product of the two numbers rolled is odd.
3)Find the probability of getting an odd number. In this case, you will calculate the probability, P(E), of event E, in which the product of the two numbers rolled is odd. Write the probability as a fraction reduced to lowest terms and as a decimal correct to two places.
Answers
Answer:
Step-by-step explanation:
They are saying the player gets points if the PRODUCT of the two numbers rolled is odd not the SUM So the answer should be
(1,3) (1,5) (3,1) (3,3) (3,5) (5,1)(5,3)(5,5) which is 9 out of 36 which would be 1/4 or 0.25
Final answer:
In this activity, the student needs to calculate the number of outcomes in the sample space, list and count the outcomes for event E, and find the probability of getting an odd number.
P(E) = 9/36 = 1/4 = 0.25.
Explanation:
To find the number of outcomes in the sample space (n(S)) of the trial, we need to consider all the possible combinations of rolling two six-sided dice. Since each die has six sides, the total number of outcomes for each die is 6. To find the total outcomes in the sample space, we multiply the outcomes for each die: n(S) = 6 * 6 = 36.
In this game, we are interested in the outcomes where the product of the two numbers rolled is odd. To list and count these outcomes, we need to consider the combinations where one or both of the numbers rolled is odd. By listing all the possible outcomes, we have: (1, 1), (1, 3), (1, 5), (3, 1), (3, 3), (3, 5), (5, 1), (5, 3), (5, 5). There are 9 outcomes for event E.
To find the probability of getting an odd number, we need to divide the number of outcomes for event E by the total number of outcomes in the sample space. P(E) = 9/36 = 1/4 = 0.25.

Sandra got a 3/27 balloon mortgage and her initial payments were $945. She decided to refinance her balloon payment with a 30-year mortgage and her new payments were $937. What is the total financed cost she paid for her house?
Answers
Sandra got a 3/27 balloon mortgage and her initial payments were $945.
This means Sandra paid $945 per month for 3 years. Total payment made in 3 years = 945*3*12 = $34,020
Later, she decided to refinance her balloon payment with a 30-year mortgage. Her new payments were $937.
Payment made under mortgage = 937 * 30 * 12 = $337,320
The total financed cost she paid for her house = $34020 + $ 337320 = $371340

Each of two trapezoidal prisms has a volume of 120 cubic centimeters. the prisms have no dimensions in common. give possible dimensions for each prism.

If the height of one trapezoid is 4, the area would need to be 30. I wrote out the formula for area of a trapezoid (h (b1+b2)/2) and solved for 30.

For the second trapezoid, I used 6 as the height of the prism. This left me with 20 as the area. I used the same formula above and found that I needed to get 40. I used 5 as the height of the trapezoid and 1 and 7 as the two base lengths. Hope this helps!!
f(x)=9x^3+2x^2-5x+4 and g(x)=5x^3-7x+4 what isf(x)-g(x)
Answers
f(x) - g(x) = 4x³ + 2x² + 2x
Explanation:
We are given that:
f(x) = 9x³ + 2x² - 5x + 4
g(x) = 5x³ - 7x + 4
We want to get the value of f(x) - g(x). This means that we will simply subtract g(x) from f(x) as follows:
f(x) - g(x) = 9x³ + 2x² - 5x + 4 - (5x³ - 7x + 4)
f(x) - g(x) = 9x³ + 2x² - 5x + 4 - 5x³ + 7x - 4
f(x) - g(x) = 9x³ - 5x³ + 2x² - 5x + 7x + 4 - 4
f(x) - g(x) = 4x³ + 2x² + 2x

Answer:
19.3 square units .
Step-by-step explanation:
∠D=∠F=52°
Opposite sides of equal angles are equal .
So, DE=EF =6.3
Now sum of all angles of triangle is 180°
So, ∠D+∠F+∠E = 180°
52°+52°+∠E =180°
104°+∠E =180°
∠E =180°-104°
∠E =76°
Now to find the length of DF we will use law of cosines

[tex]DF^2=98.582[/tex]
[tex]DF=\sqrt{98.582}[/tex]
[tex]DF=9.9[/tex]
Now we are supposed to find the area of triangle
To calculate the area of given triangle we will use the heron's formula :
[tex]Area = \sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where [tex]s = \frac{a+b+c}{2}[/tex]
a,b,c are the side lengths of triangle
Now substitute the values :
[tex]s = \frac{6.3+6.3+9.9}{2}[/tex]
[tex]s =11.25[/tex]
[tex]Area = \sqrt{11.25(11.25-6.3)(11.25-6.3)(11.25-9.9)}[/tex]
[tex]Area = 19.2907[/tex]
Hence the area of the triangle is 19.2907 ≈19.3 square units .
