Trey must pay $2420 in income tax for last year.
To solve this problemBased on the tax rates, we'll divide his taxable income into two halves.
The first portion is the minimal amount of Trey's taxable income between $9500 and $20,000 that is subject to a 10% tax rate. Consequently, the first component is $9500.
The second portion is the amount over $9500, which is $20,000 - $9500 = $10,500.
Now, let's calculate the tax for each portion:
Tax on the first portion (10% rate) = $9500 * 0.10 = $950.
Tax on the second portion (14% rate) = $10,500 * 0.14 = $1470.
We sum up the taxes on both portions to find Trey's total income tax:
Total income tax = Tax on the first portion + Tax on the second portion = $950 + $1470 = $2420.
So, Trey must pay $2420 in income tax for last year.

5. Find an expression to represent the area that is shaded
r
Answer:
(4 - π)r²
= 0.86 r²
Step-by-step explanation:
The radius of the circle = r
The diammeter of the circle = 2r
Area of circle = πr²
The side of the square = diammeter of the circle = 2r
The area of the square = (2r)² = 4r²
Area of shaded region = ar(square) - ar(circle)
= 4r² - πr²
= (4 - π)r²
= (4 - 3.14)r²
= 0.86 r²
Janelle wants to put a fountain so that it is
5 units from statues A and B. What are possible
coordinates for the fountain? Explain.
Coordinate A: (-2,-1)
Coordinate B: (4,-1)
The possible coordinates for the fountain are (-11/4, -5/2) and (-11/4, 5/2),
What are possible coordinates for the fountain?To find the possible coordinates for the fountain that is 5 units away from both statues A and B, we can use the concept of distance formula.
The distance between two points (x1, y1) and (x2, y2) can be calculated using the distance formula:
d = √((x₂ - x₁)² + (y₂ - y₁))
In this case, the coordinates for statue A are (-2, -1) and the coordinates for statue B are (4, -1).
Let's assume the coordinates for the fountain are (x, y). We want the distance between the fountain and both statues to be 5 units.
Using the distance formula for statue A:
5 = √((-2 - x)² + (-1 - y)²)
Simplifying:
25 = (-2 - x)² + (-1 - y)² (equation 1)
Using the distance formula for statue B:
5 = √((4 - x)² + (-1 - y)²)
Simplifying:
25 = (4 - x)²+ (-1 - y)² (equation 2)
We have a system of equations (equation 1 and equation 2) that represents the conditions for the fountain's coordinates.
By solving this system of equations, we can find the possible coordinates for the fountain.
Note: The solution to this system of equations will provide two sets of coordinates that satisfy the given conditions.
To solve the equations, we can expand and simplify:
From equation 1:
25 = 4 + 4x + x² + 1 + 2y + y²
x² + y² + 4x + 2y - 20 = 0 (equation 3)
From equation 2:
25 = 16 - 8x + x² + 1 + 2y + y²
x² + y² - 8x + 2y - 9 = 0 (equation 4)
Now, we can solve equations 3 and 4 simultaneously.
Subtracting equation 4 from equation 3 we get:
(8x - 4x) + (-9 + 20) = 0
4x + 11 = 0
4x = -11
x = -11/4
Substituting the value of x back into equation 3:
(-11/4)² + y² + 4(-11/4) + 2y - 20 = 0
y² + 2y - 25/4 = 0
Solving this quadratic equation, we can find the possible values of y. Factoring the equation:
(y + 5/2)(y - 5/2) = 0
This gives us two solutions:
y + 5/2 = 0 -> y = -5/2
y - 5/2 = 0 -> y = 5/2
Therefore, the two possible coordinates for the fountain are (-11/4, -5/2) and (-11/4, 5/2).

To find the product of (2x + 3) and (4x^2 - 5x + 6), we need to use the distributive property. We multiply each term in the first binomial by each term in the second binomial and then combine like terms.
Let's go through the steps:
1. Distribute the second binomial to each term in the first binomial:
(2x + 3)(4x^2 - 5x + 6) = 2x(4x^2 - 5x + 6) + 3(4x^2 - 5x + 6)
2. Multiply each term in the first binomial by each term in the second binomial:

Martina is a scientist who is studying the effects of a new diabetes medication. She sets up an experiment and divides participants into two groups. Group A gets a placebo; Group B gets the new drug. Which of the following is a correct pairing of possible null and alternative hypotheses for this experiment?
A correct pairing of possible null and alternative hypotheses for this experiment could be:
Null Hypothesis (H0): The new diabetes medication has no effect on the participants' glucose levels.
Alternative Hypothesis (H1): The new diabetes medication has a significant effect on reducing the participants' glucose levels.In hypothesis testing, the null hypothesis (H0) represents the default assumption or the statement of no effect or no difference. In this case, the null hypothesis states that the new diabetes medication has no effect on the participants' glucose levels. It assumes that there is no difference between the placebo group and the group receiving the new drug.
On the other hand, the alternative hypothesis (H1) represents the claim or the statement of an effect or a difference. In this case, the alternative hypothesis states that the new diabetes medication has a significant effect on reducing the participants' glucose levels. It suggests that there is a difference between the placebo group and the group receiving the new drug, indicating that the medication has a measurable impact on glucose levels.
By setting up these null and alternative hypotheses, Martina can conduct statistical tests and analyze the data to determine if there is enough evidence to reject the null hypothesis in favor of the alternative hypothesis, providing evidence for the effectiveness of the new diabetes medication.

The equation does not have a unique solution for x. It is true for any value of x.
The given equation is:
(5/7)(x + 2) - (3/7)x = (2/7)(x + 5)
To solve for x, we'll first simplify both sides of the equation using the distributive property and combining like terms:
[(5/7)x + (5/7)(2)] - (3/7)x = [(2/7)x + (2/7)(5)]

(5/7)x + 10/7 - (3/7)x = (2/7)x + 10/7
Next, we'll collect the x terms on one side and the constant terms on the other side of the equation:
(5/7)x - (3/7)x - (2/7)x = 10/7 - 10/7
Combining like terms:
[(5/7) - (3/7) - (2/7)]x = 0
Simplifying further:

The best answer choice among the given options is O 15 m², as none of the provided options match the correct Ccalculation.
To find the area of a rhombus, we need the lengths of the diagonals. In this case, the lengths of the diagonals are not provided. However, we can use the given information to determine the area based on the side lengths.
A rhombus is a quadrilateral with all sides of equal length, so the given side lengths of 5.5 m and 2 m can help us find the area.
We know that the diagonals of a rhombus bisect each other at right angles, dividing the rhombus into four congruent right triangles. Each side of the rhombus is the hypotenuse of one of these triangles.
Given that the side length is 5.5 m, we can consider one of these right triangles. One leg of the right triangle is half of the side length, which is (5.5 m)/2 = 2.75 m. The other leg of the triangle is the length of the diagonal, which is unknown.
Using the Pythagorean theorem, we can find the length of the diagonal:
(diagonal)^2 = (leg)^2 + (leg)^2
(diagonal)^2 = (2.75 m)^2 + (2 m)^2
(diagonal)^2 = 7.5625 m² + 4 m²
(diagonal)^2 = 11.5625 m²
diagonal ≈ √11.5625 m ≈ 3.4 m (rounded to the nearest tenth)
Since the diagonals of a rhombus are perpendicular bisectors of each other, the length of the other diagonal would also be approximately 3.4 m.
Now, we can calculate the area of the rhombus using the formula: area = (diagonal1 * diagonal2) / 2
area = (3.4 m * 3.4 m) / 2
area = 5.8 m²
The area of the rhombus is approximately 5.8 m².

Step-by-step explanation:
In the right triangle ΔABC, ∠ABC = 90 and two angles = 45,
∠ACB = ∠BAC = 45
Therefore, the sides opposite to these angles are equal
⇒ x = z
By Pythagorean theorem,
x² + z² = y²
⇒ x² + x² = y²
⇒ 2x² = y² -----eq(1)
In the right triangle ΔABD,
∠ADB = 90
∠BAD = 45 (since ∠BAC = 45)
⇒ ∠ABD = 180 - 90 - 45
⇒ ∠ABD = 45
Since ∠BAD = ∠ABD = 45, the sides opposite to these angles are equal
⇒ AD = 3
Also since ΔABC is an isoceles triangle, BD bisects AC
⇒ AD = DC = AC/2 = y/2
⇒ y/ 2 = AD
⇒ y = 2AD
⇒ y = 2(3)
⇒ y = 6
From eq(1)
2x² = y²

What is the solution to X cubed plus X squared is less than or equal to 10 X -8
The solution to the inequality x^3 + x^2 ≤ 10x - 8 is x ≤ -2 or -1 ≤ x ≤ 1.
To find the solution to the inequality x^3 + x^2 ≤ 10x - 8, we need to determine the values of x that satisfy this inequality. Let's break down the problem step by step.
First, let's bring all terms to one side of the inequality to get a cubic equation: x^3 + x^2 - 10x + 8 ≤ 0.
To solve this inequality, we can employ various methods, such as graphing, factoring, or using calculus. However, since the degree of the polynomial is relatively low, we can use a simpler approach.
We start by finding the critical points where the polynomial changes its behavior. To do this, we set the equation equal to zero: x^3 + x^2 - 10x + 8 = 0.
Next, we can use synthetic division or long division to find the factors of the polynomial. By performing this calculation, we find that x = -2 is a factor. Using synthetic division again, we can divide the polynomial by (x + 2) to obtain a quadratic equation: (x + 2)(x^2 - x + 4) = 0.
Setting each factor equal to zero gives us two additional solutions: x = 1 ± √15i. However, since we are dealing with a real-valued inequality, we only consider the real solutions. Therefore, x = -2 is the only real root.
Now, we have identified the critical point x = -2. We can plot this on a number line and choose test points within each interval to determine if they satisfy the inequality. By evaluating the inequality for these test points, we find that the solution is x ≤ -2 or -1 ≤ x ≤ 1.
To summarize, the solution to the inequality x^3 + x^2 ≤ 10x - 8 is x ≤ -2 or -1 ≤ x ≤ 1.

To find the total number of sweets in 3 boxes and 2 packets, we need to add the number of sweets in the boxes and the number of sweets in the packets.
Let's start by finding the number of sweets in 3 boxes. Since there are x sweets in each box, the total number of sweets in 3 boxes would be 3x.
Next, let's determine the number of sweets in 2 packets. If there are y sweets in each packet, the total number of sweets in 2 packets would be 2y.
To find the total number of sweets in 3 boxes and 2 packets, we can add the two quantities we calculated:
Total number of sweets = 3x + 2y
So, the expression, in terms of x and y, for the total number of sweets in 3 boxes and 2 packets is 3x + 2y.
This expression represents the combined count of sweets from the boxes and packets, accounting for the given variables x and y.

A quilt piece is designed with four congruent triangles to form a rhombus so that one of the diagonals is equal to the side length of the rhombus.Which measures are true for the quilt piece? Select three options
Answer:
THE FOLLOWING MEASURES ARE TRUE FOR THE QUILT:
1. a = 60°
3. The perimeter of the rhombus is 16 inches.
5. The length of the longer diagonal is approximately 7 inches
Step-by-step explanation:
I have attached the picture describing the rhombus.
One by one we will check all the options:
As we can see that:
a+30°=90°
a = 90-30
1) a= 60° which is true
Taking the triangle with the perpendicular x, and using pythagoras theorem, we get:
=16-4 = 12
x= =3.46 ≠3
So option 2, is not true.
Carmen plans to buy a used truck by paying a $2000 down payment and financing the
remaining $18000 with a 3-year auto loan at 4% annual interest compounding monthly. What is the total cost of the truck including all payments and down payment? rounded to 2 decimal places. Do not include the $ symbol.
Step-by-step explanation:
To calculate the total cost of the truck including all payments and down payment, we can use the formula for the future value of an annuity due:
FV = PMT × (((1 + r/n)^(n×t) - 1) / (r/n)) + PV × (1 + r/n)^(n×t)
where:
- FV is the future value of the annuity due (the total cost of the truck including all payments and down payment)
- PMT is the monthly payment
- r is the annual interest rate (4%)
- n is the number of times interest is compounded per year (12 for monthly compounding)
- t is the number of years (3)
- PV is the present value of the annuity due (the amount financed after the down payment)
First, we need to calculate the monthly payment:
PMT = (r/n) × PV / (1 - (1 + r/n)^(-n×t))
PV = $18,000 - $2,000 = $16,000
PMT = (0.04/12) × 16000 / (1 - (1 + 0.04/12)^(-12×3)) = **$470.98**
Now we can calculate the future value of the annuity due:
FV = PMT × (((1 + r/n)^(n×t) - 1) / (r/n)) + PV × (1 + r/n)^(n×t)
FV = 470.98 × (((1 + 0.04/12)^(12×3) - 1) / (0.04/12)) + 16000 × (1 + 0.04/12)^(12×3) = **$19,981.63**
Therefore, the total cost of the truck including all payments and down payment is **$21,981.63**.
Question 5 of 10
A triangle has two sides of lengths 4 and 7. What value could the length of
the third side be? Check all that apply.
A. 7
B. 9
C. 11
OD. 5
E. 17
OF. 3
The possible lengths for the third side are B. 9, C. 11, and OD. 5.
To determine the possible lengths of the third side of a triangle, we need to apply the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side.
Let's analyze the given options:
A. 7: This cannot be the length of the third side since it is equal to one of the given sides, which violates the triangle inequality theorem.
B. 9: This could be the length of the third side. 4 + 7 > 9, and 7 + 9 > 4, satisfying the triangle inequality theorem.
C. 11: This could be the length of the third side. 4 + 7 > 11, and 7 + 11 > 4, satisfying the triangle inequality theorem.
OD. 5: This could be the length of the third side. 4 + 7 > 5, and 5 + 7 > 4, satisfying the triangle inequality theorem.
E. 17: This cannot be the length of the third side since the sum of the two given sides is 4 + 7 = 11, which is less than 17. Therefore, the triangle inequality theorem is violated.
OF. 3: This cannot be the length of the third side since it is less than the length of either of the given sides. Therefore, the triangle inequality theorem is violated.
Based on the analysis, the possible lengths for the third side are B. 9, C. 11, and OD. 5.

Please help me out with this
Answer:
I would say D
Step-by-step explanation:
since it already tells you what y equals it makes it easier to substitute the others take more work so the best first step is substituting for y
Answer:
Option D) Substitute for y in the first equation
Step-by-step explanation:
When solving for a system of equation, we always need 1 equation to have x or y already isolated by itself. This makes it easy to substitute that variable into the other equation, solve, then substitute the other variable into another equation.
This will give us an ordered pair, known as the solution.
In this system, we have 2 equations. In the first one, we have no variables isolated. In the second one, we have y isolated on the left side of the equal sign. This means we can take what y equals (3x+2) and substitute that in for y in the first equation.
Hope this helps! :)
Here is a table of values for y= f(x).
x -2 -1 0 1 2 3 4 5 6
f(x) 5 6 7 8 9 10 11 12 13
Mark the statements that are true.
A. The domain for f(x) is the set {-2, -1, 0, 1, 2, 3, 4, 5, 6).
B. The range for f(x) is all real numbers.
C. f(-1) = 6
D. f(5) = -2
The statements that are true are:
A. The domain for f(x) is the set {-2, -1, 0, 1, 2, 3, 4, 5, 6).
C. f(-1) = 6
To determine the truth of each statement, we need to analyze the given table of values for the function f(x).
A. The domain for f(x) is the set {-2, -1, 0, 1, 2, 3, 4, 5, 6).
The x-values listed in the table are -2, -1, 0, 1, 2, 3, 4, 5, and 6. These are the inputs for the function, and therefore, they represent the domain of f(x). Thus, statement A is true.
B. The range for f(x) is all real numbers.
Looking at the y-values listed in the table for f(x), we can see that the range of f(x) is from 5 to 13. It does not include all real numbers, so statement B is false.
C. f(-1) = 6
From the table, we can see that when x = -1, f(x) = 6. Thus, statement C is true.
D. f(5) = -2
There is no entry in the table for f(5), so we cannot determine the value of f(5) from the given information. Therefore, statement D is false.
In conclusion, the true statements are A and C.
