Tabitha transferred a balance of $7800 to a new credit card at the beginning of the year. The card offered an introductory APR of 5.2% for the first 5 months and a standard APR of 33.6% thereafter. If the card compounds interest monthly, what will Tabitha's balance be at the end of the year? Assume that Tabitha will make no payments or new purchases during the year, and ignore any possible late payment fees.)
Answer:
The answer is $9669.65 ≈ $9670.
Step-by-step explanation:
The formula to be used is :
[tex]A=P(1+r)^{nt}[/tex]
For first part :
p = 7800
r = [tex]5.2/100/12=0.00433[/tex]
t = 5
[tex]A=7800(1.00433)^{5}[/tex]
A = $7970.04
For second part:
p = 7970.04
r = [tex]33.6/100/12=0.028[/tex]
t = 7
[tex]A=7970.04(1.028)^{7}[/tex]
A = $9669.65
So, the answer is $9669.65 ≈ $9670.

Answer:

Step-by-step explanation:
choose yes or no to indicate which of the equations can be used to describe the pattern in the table (am i correct??????)
the only equation that seems to describe the pattern is:
[tex]\( b = a - 5 \)[/tex]. Therefore, option C is correct
To determine whether the given equations can describe the pattern in the table, we need to look at the values in the table and see if they satisfy the equations. However, the provided image is not completely clear, and it seems like part of the table or the values might be missing.
From what is visible in the image, it seems we have a table with two columns labeled 'a' and 'b', with 'a' taking on values from 5 to 9 and 'b' from 0 to 4. We need to check if the equations given describe the relationship between 'a' and 'b' according to the table.
The equations given are:
1. [tex]\( b + a = 5 \)[/tex]
2. [tex]\( b = a + 5 \)[/tex]
3. [tex]\( b = a - 5 \)[/tex]
4. [tex]\( a = b - 5 \)[/tex]
Without the complete table, we can't perform a full analysis, but we can explain how you would generally approach this:
- For equation 1 [tex](\( b + a = 5 \))[/tex], check if the sum of each pair of 'a' and 'b' equals 5.
- For equation 2 [tex](\( b = a + 5 \))[/tex], check if 'b' is always 5 more than 'a'.
- For equation 3 [tex](\( b = a - 5 \))[/tex], check if 'b' is always 'a' minus 5.
- For equation 4 [tex](\( a = b - 5 \))[/tex], check if 'a' is always 'b' minus 5.
Given the values for 'a' and 'b' in the table:
a | 5 | 6 | 7 | 8 | 9
b | 0 | 1 | 2 | 3 | 4
We can analyze each equation to see if it describes the pattern in the table.
1. [tex]\( b + a = 5 \)[/tex]
Let's check if the sum of 'a' and 'b' equals 5 for each pair:
- For [tex]\( a = 5 \), \( b = 0 \): \( 5 + 0 = 5 \)[/tex] (True)
- For [tex]\( a = 6 \), \( b = 1 \): \( 6 + 1 = 7 \)[/tex] (False)
- Since it is false for [tex]\( a = 6 \), \( b = 1 \)[/tex], we can already conclude that this equation does not describe the pattern.
2. [tex]\( b = a + 5 \)[/tex]
Let's check if 'b' equals 'a' plus 5:
- For [tex]\( a = 5 \), \( b = 0 \): \( 5 + 5 = 10 \)[/tex] (False)
- Since it is false for [tex]\( a = 5 \), \( b = 0 \)[/tex], this equation does not describe the pattern.
3. [tex]\( b = a - 5 \)[/tex]
Let's check if 'b' equals 'a' minus 5:
- For [tex]\( a = 5 \), \( b = 0 \): \( 5 - 5 = 0 \)[/tex] (True)
- For [tex]\( a = 6 \), \( b = 1 \): \( 6 - 5 = 1 \)[/tex] (True)
- Continuing this pattern, this equation seems to be true for all given pairs of 'a' and 'b'.
4. [tex]\( a = b - 5 \)[/tex]
This is not likely to be true since subtracting 5 from 'b' would result in negative numbers, which are not present in the 'a' values.
From the analysis, the only equation that seems to describe the pattern is:
[tex]\( b = a - 5 \)[/tex]
Let's confirm that this equation is true for all pairs of 'a' and 'b'.
The equation [tex]\( b = a - 5 \)[/tex] holds true for all pairs of 'a' and 'b' values in the table. Therefore, this equation correctly describes the pattern in the table.

Answer:
The sequence 3 , 4 , 6 , 10 , 18 described by the 2nd term is t2 = 4 and recursive definition is tn+1 = 2 tn - 2 ⇒ 4th answer
Step-by-step explanation:
* Lets revise the recursive formula
1. Determine if the sequence is arithmetic (Do you add, or subtract, the
same amount from one term to the next?)
2. Find the common difference. (The number you add or subtract.)
3. Create a recursive formula by stating the first term, and then stating
the formula to be the previous term plus the common difference.
a1 = first term;
an+1= an + d
- Where:
# a1 = the first term in the sequence
# an = the nth term in the sequence
# an+1 = the term after the nth term
# n = the term number
# d = the common difference.
* Now lets solve the problem
∵ The recursive definition is tn+1 = 2 tn - 2 and t2 = 4
- Look to the answer we have three answer with second term = 4,
1st , 2nd and 4th
- Lets find the 1st term
∵ t2 = 2 t1 - 2
∵ t2 = 4
∴ 4 = 2 t1 - 2 ⇒ add 2 to the both sides
∴ 6 = 2 t1 ⇒ divide the two sides by 2
∴ t1 = 3
- We have two answer with first term = 3, 2nd and 4th answers
* Lets find the third term
∵ t3 = 2 t2 - 2
∵ t2 = 4
∴ t3 = 2 (4) - 2 = 8 - 2 = 6
∴ The 4th answer has the third term = 6
* The 4th sequence 3 , 4 , 6 , 10 , 18 described by the 2nd term is
t2 = 4 and recursive definition is tn+1 = 2 tn - 2

A) What is the common ratio for this geometric sequence?
(blank)a2
B) What are the missing terms in the geometric sequence shown above?
Answer:
i)
-2
ii)
a0 = 5.5
a1 = -44
Step-by-step explanation:
i)
Given a geometric sequence, the common ratio is the ratio between any two adjacent values. In our case we have the following geometric sequence;
a0, -11, 22, a1, 88, -176
To find the common ratio we can simply divide 22 by -11 or divide -176 by 88;
common ratio = 22/(-11) = -2
ii)
To find a0, we use the common ratio;
(-11)/a0 = -2
a0 = (-11)/(-2)
a0 = 5.5
We do the same for a1;
88/a1 = -2
a1 = 88/(-2)
a1 = -44

Use the expression below to write an equivalent expression in standard form, and collect like terms.
Show all of the steps in your process.
(1.) 5x + 5 ( x-3y ) + 1/2 (4x - 6y)
The expression 5x + 5 ( x-3y ) + 1/2 (4x - 6y) simplifies to 12x - 18y by distributing the multiplication over addition, combining like terms, and checking the answer for reasonableness.
Explanation:To simplify the algebraic expression 5x + 5 ( x-3y ) + ½ (4x - 6y), let's start by distributing the multiplication over addition for each term inside the parentheses:
Multiply 5 by each term inside the first set of parentheses: 5 × x and 5 × (-3y), which gives us 5x - 15y.
Multiply ½ by each term inside the second set of parentheses: ½ × 4x and ½ × (-6y), resulting in 2x - 3y.
Now, combine the like terms:
The x-terms: 5x + 5x + 2x = 12x.
The y-terms: -15y - 3y = -18y.
So, the expression in standard form is 12x - 18y.
Lastly, we should check the answer to see if it is reasonable:
No like terms are left to combine.
The coefficients are summed up correctly.
The expression is simplified as much as possible.

We can solve this using the Pythagorean theorem
[tex]13^2-12^2=x^2\\\\x=\sqrt{169-144} \\\\x=\sqrt{25} \\\\x=5[/tex]
It should be 5. You would need to use the Pythagorean theorem, a^2 + b^2 = c^2 to find the length of the missing side. So it would be x^2 + 144=169, which leads to 169-144 = 25. Then you would need to get the square root of 25, which is 5. I hope that helps.

Answer:
The number of messages sent by Justin was [tex]180\ messages[/tex]
The number of messages sent by David was [tex]270\ messages[/tex]
Step-by-step explanation:
Let
x-----> number of messages sent by Justin
y----> number of messages sent by David
we know that
[tex]\frac{x}{y}=\frac{8}{12}[/tex]
[tex]x=\frac{8}{12}y[/tex] ----> equation A

[tex]\frac{20}{12}y=450[/tex]
[tex]y=450*12/20=270\ messages[/tex]
Find the value of x
[tex]x=\frac{8}{12}(270)=180\ messages[/tex]

Maria is comparing the prices of two window cleaning companies. Company A charges $6 per window and an additional $12 as service charges. Company B charges $5 per window and an additional $15 as service charges.
Part A: Write an equation to represent each company's total charges for cleaning a certain number of windows. For both equations (one for Company A and one for Company B), define the variable used.
Part B: Which company would charge less for cleaning 8 windows? Justify your answer.
Part C: How much money is saved by using the services of Company B instead of Company A to clean 6 windows?
Answer:
Step-by-step explanation:
Part A: Company A charges $6 for a window and $12 for a service clean. If you add that up it would be 6 + 12 =18 so company A would be making $18 per customer. Company B charges $15 + $5 for a whole cleaning which would make them $20 per customer. That is better then $18 so business B would be making more money.
Part B: For cleaning 8 windows company B would charge less because 8 x 5 = $40 for all the windows and company A would be charging $6 for a window which is more so 8 x 6 = 48. Company B charges less.
Part C: Company B charges 5 dollars for thier services on windows as Company A charges 6. You would be saving a dollar by buying at company B.
if line p is (2x+40)°and line q is (3x-85) what is the value of x
Solve for x: (2x + 40)° = (3x - 85)°. The solution is x = 125.
To find the value of x, you can set the expressions for the angles equal to each other since the two lines are parallel and corresponding angles are equal.
The given angles are:
- Line p: [tex]\(2x + 40\)[/tex] degrees
- Line q: [tex]\(3x - 85\)[/tex] degrees
Set them equal to each other and solve for x:
[tex]\[ 2x + 40 = 3x - 85 \][/tex]
Combine like terms:
[tex]\[ 40 + 85 = 3x - 2x \][/tex]
[tex]\[ 125 = x \][/tex]
So, the value of x is 125 degrees.
The complete question is here:
if line p is (2x+40)°and line q is (3x-85) what is the value of x
The value of ( x ) is [tex]\( 125^\circ \)[/tex].
To find the value of ( x ), we can use the properties of parallel lines cut by a transversal. When two parallel lines are cut by a transversal, alternate interior angles are congruent.
Given:
- Angle [tex]\( 2x + 40^\circ \) and angle \( 3x - 85^\circ \)[/tex] are alternate interior angles.
So, we can set up an equation:
[tex]\[ 2x + 40^\circ = 3x - 85^\circ \][/tex]
Let's solve for ( x ):
[tex]\[ 2x - 3x = -85^\circ - 40^\circ \][/tex]
[tex]\[ -x = -125^\circ \][/tex]
To isolate ( x ), we divide both sides by -1:
[tex]\[ x = \frac{-125^\circ}{-1} \][/tex]
[tex]\[ x = 125^\circ \][/tex]
So, the value of ( x ) is [tex]\( 125^\circ \)[/tex].

a certain project can be completed by 28 men in 90 days. the numbers of men needed varies inversely to the time needed to complete the project. if the contractor wants to complete the project in 72 days how many men does he have to have working?
A. 30 men
B. 270 men
C. 35 men
D. 28 men
ANSWER
C. 35 men
EXPLANATION
Let m represent the number of men needed and d represent the number of days.
From the question,the number of men needed varies inversely to the time needed to complete the project.
We can write the inverse variation equation.
[tex]m = \frac{k}{d} [/tex]
where k is the constant of variation.
When m=28, d =90.
We substitute these values into the variation equation to determine the value of k.
[tex]28 = \frac{k}{90} [/tex]
[tex]k = 90 \times 28[/tex]
[tex]k = 252[/tex]
Now the equation becomes:
[tex]m= \frac{2520}{d} [/tex]
When d=72,
[tex]m = \frac{2520}{72} [/tex]
[tex]m = 35[/tex]
Therefore he needs to have 35 men working.

At a large university, 15% of students are business majors and 20% are communications majors. If two students are selected at random, what is the probability the first is a communications major and the second is a business major?
Express your answer in decimal form using two decimal places.
Answer:
Probability the first is a communications major and the second is a business major = 0.03
Step-by-step explanation:
let the total number of students be 100
Event A= Business Majors = 15%
Event B = Communication Majors = 20%
P(A) = [tex]\frac{15}{100}[/tex] ⇒ P(A) = 0.15
P(B) = [tex]\frac{20}{100}[/tex] ⇒ P(B) = 0.2
P( A and B) = P(A) × P(B)
