Answer:

  output = -3n +1

Step-by-step explanation:

Given an input/output table for a linear function, you want an expression for the output when the input is n.

The input values count up from 1, so we can consider the output values to be the terms of an arithmetic sequence.

The first term of the sequence is a1 = -2 (when n=1).

The common difference of the sequence is d = (-5 -(-2)) = -3.

The general (n-th) term of an arithmetic sequence is given by the formula ...

   an = a1 +d(n -1)

For the known values of a1 and d, we find the n-th term to be ...

  an = -2 +(-3)(n -1)

  an = -2 -3n +3 . . . . . . . eliminate parentheses

  an = -3n +1 . . . . . . . . collect terms

The term corresponding to an input value of n is ...

  -3n +1

Answer: $178.31

Step-by-step explanation:

To calculate Heidi's overtime pay, we first need to find out how many hours she worked overtime and then multiply those hours by her overtime pay rate. The standard workweek in the United States consists of 40 hours, and any hours worked beyond 40 hours are considered overtime.

Step 1: Calculate the number of overtime hours:

Total hours worked = 47.50 hours

Standard workweek = 40 hours

Overtime hours = Total hours worked - Standard workweek = 47.50 - 40 = 7.50 hours

Step 2: Calculate Heidi's overtime pay rate:

Hourly wage = $15.85

Overtime pay rate = Hourly wage * 1.5 (overtime is typically paid at 1.5 times the regular hourly rate) = $15.85 * 1.5 = $23.775

Step 3: Calculate Heidi's overtime pay:

Overtime pay = Overtime hours * Overtime pay rate = 7.50 hours * $23.775 = $178.31 (rounded to 2 decimal places)

Heidi's overtime pay for the week is $178.31.

The area of a right triangle is given by the formula:

Area = 1/2 * base * height

Substituting the values given in the problem:

Area = 1/2 * 45 meters * 16 and 3/4 meters

To simplify the computation, we convert the mixed fraction 16 and 3/4 to an improper fraction:

16 and 3/4 = (16 * 4 + 3) / 4 = 67/4 meters

Substituting this value, we get:

Area = 1/2 * 45 meters * 67/4 meters

Simplifying:

Area = 843.75 square meters

Therefore, the area of the right triangle is 843.75 square meters.

Answer:

The answer is 22

Step-by-step explanation:

You would first start by solving for the x value. You would do 6x-7=2x+5, then start factoring out number and variable until the variable is on 1 side and the number are on the other, so it'd be 4x=12. After you would calculate for the x which is 3, which you did, then you would plug that back into the values. You'd plug 3 into 2(x)+5 which simplifies down to 6+5 which is 11 and since DB is half of AB you multiply by 2 to get 22.

The given graph is an illustration of a piecewise linear equation.

Jamie correctly described what the graph could be used for (a relay race)

Jamie wrongly described the axes of the graph, in both sections

The piece-wise function is: [tex]y=\left \{ {{\frac{1}{12}x, 0 < = x < 12} \atop {\frac{1}{8}x+\frac{1}2},12 < x < =20}} \right.[/tex]

See the attachment for the graph and Jamie's work

From the graph, we have:

Time (minutes) = x

Distance (miles) = y

(a) When the runner begins the race

From the graph, we have:

x=[0,12]

y=[0,1]

This means that the runner runs a distance of 1 mile in 12 minutes

So; Jamie's description here is wrong because he misrepresented the axes.

The equation of this part is calculated as follows:

Start by calculating the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{1-0}{12-0}=\frac{1}{12}[/tex]

The equation is then calculated using:

[tex]y=m(x-x_1)+y_1\\\\y=\frac{1}{12}(x-0)+0\\\\y=\frac{1}{12}x[/tex]

(b) When his partner takes over

From the graph, we have:

x=(12,20]

y=(1,2]

This means that his partner runs a distance of 1 mile in 8 minutes

So; Jamie's description here is also wrong because he misrepresented the axes, again.

The equation of this part is calculated as follows:

Start by calculating the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-1}{20-12}=\frac{1}{18}\\\\y=\frac{1}{8}(x-12}+1\\\\y=\frac{1}{8}x-\frac{1}{2}[/tex]

Hence, the piece-wise function can be represented as:

The piece-wise function is: [tex]y=\left \{ {{\frac{1}{12}x, 0 < = x < 12} \atop {\frac{1}{8}x+\frac{1}2},12 < x < =20}} \right.[/tex]

Answer:

  Horace

Step-by-step explanation:

You want to know if "base" refers to any particular side of a rectangle.

The formula for the area of a rectangle can be written ...

  Area = base × height

It can also be written ...

  Area = length × width

In each formula, the factors of the area refer to orthogonal dimensions of the rectangle. Any side of the rectangle can be considered to be the "base" or the "length" or the "width" or the "height". The other factor in the area formula is whatever dimension is orthogonal to that choice.

The commutative property of multiplication tells you that you get the same product if you reverse the order of the numbers.

So, you could have ...

  Area = AB·BC

or

  Area = BC·AB

If you insist that the fist of these numbers is the "base", then the base can be either AB or BC and the area will be the same.

The substitution property of equality tells you that you can substitute any equal values. Opposite sides of a rectangle are equal length, so either can be substituted for the other. In short, you can write the product for the area any of 8 ways:

  Area = AB·BC = AB·AD = BC·AB = AD·AB

  = CD·AD = CD·BC = AD·CD = BC·CD

If you want to distinguish between AB and BA, you can write this many more ways.

Horace seems to understand the fundamental interchangeability of the dimensions in the area formula. Horace has the right idea.

Bernice seems more attached to one particular understanding. We wonder what Bernice would call the "base" if the rectangle were drawn at a different angle to the grid.

Therefore, the equation of the line passing through (0, -3) and (5, -3) is y = -3.

An equation is a mathematical statement that shows the equality between two expressions. It typically consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The expressions on both sides of the equation are separated by an equals sign (=) and can be manipulated in various ways to find the value of the variable(s) that satisfies the equation.

Here,

To find the equation of the line passing through two points (x₁, y₁) and (x₂, y₂), we can use the point-slope form of a linear equation, which is:

y - y₁ = m(x - x₁)

where m is the slope of the line.

In this case, the two points are (0, -3) and (5, -3), so we have:

x₁ = 0, y₁ = -3

x₂ = 5, y₂ = -3

The slope of the line can be found using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

Substituting the values, we get:

m = (-3 - (-3)) / (5 - 0)

m = 0 / 5

m = 0

Since the slope m is zero, the line is a horizontal line.

To find the equation of the line, we can use the point-slope form with one of the points, say (0, -3). Substituting the values, we get:

y - y₁ = m(x - x₁)

y - (-3) = 0(x - 0)

y + 3 = 0

1.  Perimeter of AARG = 1.6 × 4.4 cm = 7.04 cm

2.  The measure of SBH is 162°.

3. Area of AARG = 2.56 × 0.8 cm² = 2.048 cm²

4. The length of the circumference of circle B is approximately 13.01 cm.

The circumference of a this double shape's perimeter is its total length. In other terms, it is the total length of all a shape's sides. For instance, the circumference of a circle is equal to the distance around its outside, or circumference, whereas the perimeter of a rectangle may be computed by combining the measurements of all four sides.

To solve this problem, we can use the fact that all circles are similar. This means that corresponding lengths of the circles are proportional. In particular, if the ratio of the radii of two circles is k, then the ratio of their circumferences is also k, and the ratio of their areas is k².

Let's start with finding the radius of the larger circle. Since OB/OA = 2.25, we can write:

OA + AB = OB

OA + 1 = 2.25 OA

OA = 1 / 1.25 = 0.8

Therefore, the radius of the larger circle is 0.8 cm. Since the circles are similar, the ratio of the radii is 0.8/0.5 = 1.6.

1. The perimeter of ABSH is proportional to the radius of the circle, so we have:

Perimeter of ABSH = 1.6 × Perimeter of AARG = 1.6 × 4.4 cm = 7.04 cm

2. Let x be the measure of SBH. Then we have:

RAG + SBH + HBS = 360°

108° + x + 90° = 360°

x = 162°

Therefore, the measure of SBH is 162°.

3. The area of ABSH is proportional to the square of the radius of the circle, so we have:

Area of ABSH = 1.6² × Area of AARG = 2.56 × 0.8 cm² = 2.048 cm²

4. The circumference of circle B is proportional to the radius of the circle, so we have:

Circumference of circle B = 1.6 × Circumference of circle A ≈ 1.6 × 8.13 cm ≈ 13.01 cm

Therefore, the length of the circumference of circle B is approximately 13.01 cm.

What is the percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

Let's assume that there were x grapes in the container at first.

Arianna ate 0.45 of the grapes, which means she ate 0.45x grapes.

Alex ate 35% of the grapes, which means he ate 0.35x grapes.

The total number of grapes eaten is the sum of what Arianna and Alex ate:

0.45x + 0.35x = 0.8x

This means that 0.8x grapes were eaten, and the number of grapes left is x - 0.8x = 0.2x.

We know that there were 18 grapes left, so we can set up an equation:

0.2x = 18

Solving for x, we get:

x = 90

Therefore, there were 90 grapes in the container at first.

Total number of residents in Percy's town = 5,320 + 1,680 = 7,000 Number of residents who participated = 5,320 Percentage of residents who participated = (Number of participants / Total number of residents) x 100 = (5,320 / 7,000) x 100 = 76% Therefore, 76% of the residents of Percy's town participated in the recycling drive.

Answer:

The correct answer is 76%.

Step-by-step explanation:

To find the percentage of Percy's town that participated in the recycling drive, we must divide the number of people that participated by the total number of residents.

To do this, we should first find the total number of residents. Since residents either participated or did not participate, the total number of residents is the sum of these two values. This is modeled below:

Total number of residents = 5,320 + 1,680 = 7,000 total residents

Now, we can continue with the percentage calculation.

% participation = # of participants/# of residents * 100

% participation = 5,320/7,000 * 100

% participation = 76%

Therefore, we can conclude that 76% of Percy's town participated in the recycling drive.

The probability that the mean weight of two fruits picked at random falls between 360 grams and 491 grams is approximately 0.9554 or 95.54%.

To solve this problem, we need to use the formula for the sampling distribution of the sample mean:

x' = μ/√n

where x' is the sample mean, μ is the population mean, and n is the sample size.

Given that the population mean is 443 grams and the standard deviation is 34 grams, we can calculate the standard error of the sample mean:

SE = σ/√n

  = 34/√2

  ≈ 24.04 grams

Now we need to standardize the sample mean to a standard normal distribution using the z-score formula:

z = (x' - μ)/SE

The probability that the sample mean falls between 360 grams and 491 grams is equivalent to the probability that the z-score falls between:

z = (360 - 443)/24.04 ≈ -3.45 and z = (491 - 443)/24.04 ≈ 1.99

The work required to pump the water out of the hemispherical tank is 5,930,818.125 ft-lb.

To find the work required to pump the water out of the hemispherical tank, we need to consider the following steps:
Step 1: Determine the volume of the hemispherical tank.
The formula for the volume of a hemisphere is (2/3)πr³,

where r is the radius.

Given the radius is 13 ft, we can calculate the volume as follows:
Volume = (2/3)π(13³)

= (2/3)π(2197)

= 14603.86 ft³.
Step 2: Calculate the weight of the water in the tank.
Given the water weighs 62.5 lb/ft³, we can determine the weight of the water in the tank by multiplying the volume by the water weight:
Water weight = Volume × Weight/ft³

= 14603.86 ft³ × 62.5 lb/ft³

= 912741.25 lb.
Step 3: Determine the average height at which the water must be pumped out.
Since the tank is hemispherical, the average height for pumping the water is half the radius (13 ft).

So, the average height is:
Average height = 13 ft ÷ 2 = 6.5 ft.
Step 4: Calculate the work required to pump the water out of the tank.
Work = Weight × Distance × Force of gravity.

where Force of gravity = 1 (as we're working with pounds and feet, the force of gravity is already accounted for).
Work = 912741.25 lb × 6.5 ft × 1 = 5930818.125 ft-lb.
