Chad and Amy are married with no children, and they're filing their federal
income tax return. Chad had a gross income of $54,300 last year, while Amy had
a gross income of $50,900; they plan to use the standard deduction. They're

The 29th term in the given arithmetic sequence is −170.

An arithmetic sequence can be defined in one of two ways. In an arithmetic sequence, "each term is obtained by adding a fixed number (positive or negative or zero) to its preceding term," or "each term is obtained where the differences between every two successive terms are the same." The arithmetic sequence that comes next is created by adding 4 to the term that comes before it.

Given that 89th term in an arithmetic sequence is -590

And 8th term is -23

-590 = a₁ + (89 - 1)d

-590 = a₁ + 88d

a₁ = -590 - 88d

and

-23 = a₁ + (8 - 1)d

-23 = a₁ + 7d

a₁ = -23 - 7d

Factor out a₁ in both equations

-590 - 88d =  -23 - 7d

-88d + 7d = 590 - 23

-81d = 567

d = -567.81

d = −7

As we have the d lets find fist term

a₁ = -23 - 7(-7)

a₁ = -23 + 49

a₁ = 26

Now, find  29th term

a₂₉ = 26 + (29 - 1)(−7)

a₂₉ = −170

Thus, the 29th term in the given arithmetic sequence is −170.

The sum of the interior angles for a Polygon of 5 angles is 540°

An angle is the opening formed by two half-straights (sides) with the same origin called vertex. For example, within a triangle there are three angles, which in total add up to 180°.

The sum of the interior angles of a Polygon is calculating by the formulation:

Sum of Interior Angles = (n-2) x 180°

Replacing the number of angles (n = 5) in the equation we get:

Sum of Interior Angles = (n-2) x 180°

Sum of Interior Angles = (5-2) x 180°

Sum of Interior Angles = 3 x 180°

Feynman says Phlogiston Theory was not scientific is because it didn't utilized methods that were related to science.

The phlogiston theory, a debunked scientific hypothesis, suggested that combustible bodies contained a fire-like substance called phlogiston, which was released during combustion. Johann Joachim Becher first put forth the concept in 1667, and Georg Ernst Stahl later formalized it. Phlogiston theory sought to explain oxidation, the modern term for chemical processes like combustion and rusting.

According to the phlogiston theory, when something is burned, it dephlogisticates, releasing stored phlogiston that is then taken in by the air. The phlogiston is then absorbed by developing plants, which is why air does not spontaneously ignite and why plant matter burns so effectively.

The distance between Point P and Point Q on the number line is the absolute value of the difference between the coordinates of the two points.

In other words, if Point P has coordinate x and Point Q has coordinate y, then the distance between the two points is |x - y|. For example, if Point P has coordinate 3 and Point Q has coordinate 7, then the distance between the two points is |3 - 7| = |-4| = 4. This is because it is measuring the distance between two points in one dimension, that is on the number line.

The number line is a visual representation of the set of real numbers. It is a straight line with points that correspond to the numbers on the line. Each point on the number line corresponds to a unique real number, and the position of the point on the line indicates its value. The numbers on the left side of the number line are generally considered as negatives and the numbers on the right side as positives.

The area of square A is 25 in² and each side measures 5 inches

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

For square B:

Area = side²

144 = side²

side = 12 in

For square C:

Area = side²

169 = side²

side = 13 in

To find the length of each square A side, we use Pythagoras theorem. Hence:

(Side C)² = (Side A)² + (side B)²

13² = (side A)² + 12²

169 = (side A)² + 144

(side A)² = 25

Side A = 5 in

As we know, 1 hour has 60 minutes.

So, total time in hour = 1 + 15/60

Total time in hour = 1.25 hours

The speed, distance and time are related as -

Average speed = total distance travelled ÷ total time taken

If we use the method of completing the square to solve the quadratic equation x² + 5x - 1 = 0, we have to add (-25/4) to convert it to (x + 5/2)²  - 29/4 = 0

The standard form of a quadratic equation is:

ax² + bc + c = 0

In this case, the quadratic function is:

x² + 5x - 1 = 0

To solve it using the "complete the square" method, write the equation as:

(x + 5/2)² - 1 + .... = 0

The blank part in the above equation means we need to add a number to make the equality still holds.

Note that:

(x + 5/2)² = x² + 5x + 25/4

The ratio between of the two legs of a 30-60-90 triangle:

√3 : 2.

The correct option is D.

It is a triangle with constant angles of 30, 60, and 90. This triangle is always a right triangle, as one of the angles is 90 degrees. Thus, a right-angled triangle is formed by these angles. Additionally, the right angle is equal to the sum of two acute angles, which will have a 1: 2 or 2: 1 ratio.

Given:

A triangle is a 30-60-90 triangle.

So, the sides of a 30-60-90 triangle are always in the ratio of 1:√3: 2.

The side opposite is 60° is √3.

We can identify the boundary line with the inequality symbol.

We use a dotted boundary line if the inequality symbol is greater than or less than. This indicates that the answers are not part of the borderline.

We will use a solid line to denote that the solutions are included on the boundary line if the inequality symbol is greater than or equal to or less than or equal to.

Let X be the random variable representing the waiting time.

Here the mean = 203 days

Standard deviation (∑∝) = 25.7 days

For calculating the 5th percentile, we need to find the z- score having area 0.05.

By Z-score table we have Z= -1.64

Now, Using formula X=Z\standard deviation +mean

X = (-1.64)*(25.7)+203

 = 160.852 days

Waiting time representing 5th percentile = 160.852 days.

For calculating third quartile, we know that third quartile represents the area to the left of 75% = 0.75

It means that the area of the gingerbread house Hillary will cover with icing is 0 cm^2.

To find the area of the gingerbread house that Hillary plans to cover with icing, we need to subtract the area of the window and the door from the total area of the front of the house.

The window measures 2 cm x 2.5 cm, so the area of the window is 2 cm x 2.5 cm = 5 cm^2

The door measures 2 cm x 3 cm, so the area of the door is 2 cm x 3 cm = 6 cm^2

The total area of the front of the house is the sum of the areas of the window and door, so we can find it by adding 5 cm^2 + 6 cm^2 = 11 cm^2

To find the area of the gingerbread house Hillary will cover with icing, we need to subtract the area of the window and the door from the total area of the front of the house:

Area of gingerbread house covered with icing = Total area of front of house - Area of window - Area of door

Area of gingerbread house covered with icing = 11 cm^2 - 5 cm^2 - 6 cm^2 = 0 cm^2

It means that the area of the gingerbread house Hillary will cover with icing is 0 cm^2. This means that the area of the window and door are equal to the total area of the front of the house and there's no space left to put icing on.

The following are the zeros for the function h (x) = x2 + 3x - 8: - x= -4 and x=2.

Given a collection of inputs X (domain) and a set of potential outputs Y (codomain), a function is more technically defined as a set of ordered pairings (x,y) where xX and yY with the caveat that there can only be one ordered pair with the same value of x. The function notation f:XY can be used to express that f is a function from X to Y.

The function's zero is a value of x that makes it equal to zero. In other words, the equation f(x) = 0 leads to a zero.

By putting h(x) equal to zero and figuring out x, we may determine the zeroes for the function h(x) = x2 + 3x - 8.

h(x) = x² + 3x - 8 = 0

We may factor the left side of the equation to find x:

x² + 3x - 8 = (x-2)(x+4) = 0

We set each factor to zero and solve for x to discover the zeroes:

x-2 = 0 or x+4 = 0

x = 2 or x = -4

Consequently, the function's zeros are x = 2 and x = -4.
