Step-by-step explanation:
Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, HCF).
When graphed, the function gives a line with a slope of 1.55. See the figure below.
If the monthly cost for 15 HCF is $47.84, what is the monthly cost for 9 HCF?
Answer:
The monthly cost for 9 HCF is $38.54
Step-by-step explanation:
The graph is missing; however, the question can still be solved
Given
Slope = 1.55
When monthly cost = $47.84, Amount of water = 15 HCF
Required
Determine the monthly cost for 9 HCF
From the question, we understand that it is a linear function;
Linear functions are of the form
[tex]y = mx + b[/tex]
Where y is the function of x and m is the slope
In this case; the function is the monthly water bill
and x is the amount of water
Solving for b
When monthly cost = $47.84, Amount of water = 15 HCF
The function is as follows;
[tex]47.84 = 1.55 * 15 + b[/tex]
[tex]47.84 = 23.25 + b[/tex]
Subtract 23.25 from both sides
[tex]47.84 - 23.25= 23.25 - 23.25 + b[/tex]
[tex]24.59 = b[/tex]
[tex]b = 24.59[/tex]
Solving for the monthly cost for 9 HCF
Here, we have that
[tex]x = Amount\ of\ water = 9[/tex]
[tex]m = Slope = 1.55[/tex]
[tex]b = 24.59[/tex]
Substitute these values in the linear function; [tex]y = mx + b[/tex]
[tex]y = 1.55 * 9 + 24.59[/tex]
[tex]y = 13.95 + 24.59[/tex]
[tex]y = 38.54[/tex]
Hence, the monthly cost for 9 HCF is $38.54
Complete the recursive formula of the arithmetic sequence -17, -8, 1, 10,... a(1)= a(n)=a(n-1)+
To find a(1), simply look at the first term, which is -17. This gives a starting point for the recursive formula.
Then, we want to write the recursive formula as a(n) = a(n - 1) + c, where c is the number you add to a term to get the next term. You can see from the values given that you are adding 9 to each term to get the next one, so the recursive formula would be a(n) = a(n - 1) + 9.
First term of sequence of arithmetic (a₁) is -17 and aₙ is -17 + 9(n-1)
What is arithmetic sequence?
A arithmetic sequence is defined as an arrangement of numbers which is particular order.
The formula to find the general term of an arithmetic sequence is,
aₙ = a₁ + (n-1)d
What is geometric sequence?The geometric sequence defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Given data :
The arithmetic sequence -17, -8, 1, 10,...
First term of sequence of arithmetic (a₁) = -17
The common difference of arithmetic (d) = difference between the two term
The common difference of arithmetic (d) = -8 - (-17)
The common difference of arithmetic (d) = -8 + 17
The common difference of arithmetic (d) = 9
To determine the n term of arithmetic sequence
The nth term of a arithmetic sequence is expressed as :
aₙ = a₁ + (n-1)d
substitute the values of a₁ and d in the formula,
aₙ = -17 + (n-1)9
Let n = 5
a₅ = -17 + (5 - 1)9
a₅ = -17 + (4)9
a₅ = -17 + 45
a₅ = 28

Find the lengths and slopes of the diagonals to name the parallelogram. Choose the most specific name. E (-2, -4), F(0, -1), G(-3. 1) H(-5, -2) Note: Be prepared to explain your answer to this type of question on the test using length and slope. a) Rectangle b) Triangle c) Rhombus d) Square ---------------------------------------------------------------------------------------------------------------------------- What would prove the parallelogram PWRS is a rhombus? P(-1, 3), Q(-2, 5), R(0, 4), S(1, 2) a)Length of QR is 2.2 and slope of QR is -2 b) Slope of QR and PS is -2 and Slope of RS and QP is -1/2 c) Length of QS and PR is 4.2 d) Length of QR and PS is 2.2 and Length of RS and QP is 2.2
Detailed explanation:
The diagonals of the parallelogram must be measured in order to ascertain its name. Let's figure out these numbers:
The slope of the EF is equal to (y2 - y1) / (x2 - x1) = (-1 - (-4)) / (0 - (-2)) = 3 / 2.
Diagonal GH: [(x2 - x1)2 + (y2 - y1)2] is the length of the GH.
= √[(-5 - (-3))² + (-2 - 1)²]
= √[(-2)² + (-3)²]
= √[4 + 9] = √13
Slope of GH is equal to (y2 - y1)/(x2 - x1) = (-2 - 1)/(-5 - (-3)) = -3 / -2 = 3 / 2
Let's examine the outcomes now:
The parallelogram is a rhombus if the lengths of both diagonals are equal (EF = GH) and the slopes of both diagonals are equal (slope of EF = slope of GH).
In our case, EF = GH = √13, and the slopes of EF and GH are both 3/2. Therefore, the parallelogram is a rhombus.
Therefore, the correct answer is c) Rhombus.
For the first question, the most specific name for the parallelogram defined by the coordinates E, F, G, and H is d) Square because the lengths of the sides and the diagonals are equal.
For the second question, the statement that would prove the parallelogram PWRS is a rhombus is d) Length of QR and PS is 2.2 and Length of RS and QP is 2.2, as it shows that all sides of the parallelogram are congruent.
To determine the most specific name for the parallelogram defined by the given coordinates, we need to analyze the properties of the shape based on the lengths and slopes of its diagonals.
Let's analyze each option:
a) Rectangle: In a rectangle, opposite sides are parallel and equal in length.
Diagonals are also congruent.
To determine if the parallelogram is a rectangle, we need to find the lengths of the diagonals.
Using the distance formula, we find that the length of EF is approximately 4.47 units, while the length of GH is approximately 4.24 units.
Since the diagonals are not congruent, the parallelogram is not a rectangle.
b) Triangle: A triangle is a three-sided polygon, which is not applicable to the given parallelogram.
c) Rhombus: In a rhombus, all sides are congruent.
The diagonals of a rhombus are perpendicular bisectors of each other. To determine if the parallelogram is a rhombus, we need to compare the slopes of the diagonals.
The slope of EF is -3/2, while the slope of GH is -3/2.
Since the slopes are equal, and the lengths of the sides are not given, we cannot determine if the parallelogram is a rhombus solely based on the given information.
d) Square: A square is a special type of rectangle and rhombus, where all sides are congruent and all angles are right angles.
Since we cannot determine if the parallelogram is a rhombus, we cannot conclude that it is a square.
In conclusion, based on the given information, we cannot determine the most specific name for the parallelogram defined by the coordinates.
For the second question, to prove that the parallelogram PWRS is a rhombus, we would need to show that the lengths of the sides are congruent and that the diagonals are perpendicular bisectors of each other.
However, based on the given options, we do not have the required information to prove that PWRS is a rhombus.

Find the equation of the line: With an x intercept of 4 and ay intercept of −1.5.
Answer:
y = (3/8)x - 1.5
Step-by-step explanation:
Use the slope-intercept form y = mx + b. Substitute -1.5 for b, 4 for x and 0 for y. Then: 0 = m(4) - 1.5, or
4m = 1.5, or
The slope is m = 1.5/4, or m = 0.375, or m = 3/8.
Note that the x-intercept can be treated just like any other point: (4, 0)
Then the desired equation is y = (3/8)x - 1.5
Answer:
[tex]\boxed{y=\frac{3}{8} x-1.5}[/tex]
Step-by-step explanation:
Part 1: Determining slope from two given points
We are given the points [tex]x=4[/tex] and [tex]y=-1.5[/tex]. We can go ahead and make the first part of the equation because we are given one of the unknowns (the y-intercept, or [tex]b[/tex]). The equation becomes [tex]y=mx-1.5[/tex].
Part 2: Determine the coordinate points
[tex]x=4[/tex] is a x-intercept, meaning it crosses the x-axis at this point. The y-value is [tex]0[/tex] ⇒ [tex](4, 0)[/tex] is the first point.
[tex]y=-1.5[/tex] is a y-intercept, meaning it crosses the y-axis at this point. The x-value is [tex]0[/tex] ⇒ [tex](0, -1.5)[/tex] is the second point.
Now, plug these values into the point-slope formula: [tex]m=\frac{y_{2} -y_{1} }{x_{2}-x_{1}}[/tex]
[tex]m=\frac{-1.5 - 0}{0 - 4}[/tex][tex]m = \frac{-1.5}{-4}[/tex][tex]m = \frac{3}{8}[/tex]Plug this information into the equation to get your final answer of [tex]\boxed{y=\frac{3}{8} x-1.5}[/tex].

Students in Mr. Taylor's physics class conducted an experiment by dropping a basketball from a height of 40 feet and then recording the ball’s height after each bounce. The ball climbed to a height of 20 feet after the first bounce, and 10 feet after the second bounce. If this pattern continues, how many feet high will the ball climb after the third bounce? Input the answer using numbers only.
Answer:
The answer would be 5 feet
Step-by-step explanation:
The class dropped the ball from 40 feet than after the ball bounced again it went to 20 feet than after the 2nd bounce it went to 10 feet and the pattern so far goes 40, 20, and 10. We need to find the common pattern of these 3 numbers and find the 4th number or [tex]x[/tex] so to find the 4th number you can see that if you divide every number by 10 than you will get 4, 2, and 1 which you can see when divided by 2 every time goes to the next number so 4 divided by 2 is 2 and 2 divided by 2 is 1 so we can assume 1 divided by 2 will be x divided by 10 so 1/2 is 0.5 so x divided by 10 is equal to 0.5 so the equation would be [tex]\frac{x}{10} =0.5[/tex] so we could multiply by 10 on both sides so we would get x = 5 so the final answer would be 5.

Step-by-step explanation:
The area of a circle is found by doing pi * r^2. In this case, the diameter is 6. 6 / 2 = 3. So, r = 3.
pi * 3^2 = pi * 9 = 9pi.
This is a semicircle, so the area will be half of the whole circle.
9pi / 2 = 4.5 * pi = 4.5 * 3.14 = 14.13 units^2.

7x2 + 1 = 5x
double root
real and irrational root
real and rational root
imaginary root
Help please
Answer:
It is an imaginary root.
Step-by-step explanation:
When we rearrange the formula, we get 7x^2 - 5x + 1 = 0
When we put it in the quadratic formula: x = (−b±√b^2−4ac ) over 2a, we get x = 5 ± √-5^2-4(7)(1) over 2(7)
The discriminant is inside the square root. It is a -3. And because it is negative, we know that the root is an imaginary root.
A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each should be added to obtain 60 kg of a mix
that will sell for $1.40 per kg?
1. The amount of nuts is ____kg and cereal mixture is ____ kg to obtain 60 kg of a mix that will sell for $1.40 per kg.
Answer:
44kg of cereal, 16kg of nuts
Step-by-step explanation:
Step 1. We work out how much the party mix would cost if all of it was nuts.
$2.50 x 60kg = $150
Step 2. We work out how much we want the party mix to cost if it had the correct ratio of nuts and cereal.
$1.40 x 60kg = $84
Step 3. We work out the difference between the two above numbers.
$150 - $84 =$66
Step 4. We work out the difference between the nut mix and the cereal mix.
$2.50 - $1 = $1.50
Step 5. We divide the answer to step 3 ($66) by the difference between the nut mix and cereal mix.
$66 ÷ $1.50 = 44
Step 6. The answer to step 5 is the mass of the cereal mix. We then minus 44kg from the total mix mass of 60kg to get the mass of the nut mix.
60kg - 44kg = 16kg
Step 7. We double check.
44kg of cereal = $44 16kg of nuts = $40 $44 + $40 = $84
$84 ÷ 60kg = $1.4 per kg

Answer:
3.43
Step-by-step explanation:
To do this you would first find the area of the square which is 16. Then you would find the area of the 2 semicircle or just on whole circle. We are just going to use the formula for a whole circle since there are 2 semicircles. The formula to find a circle is pi times r^2 so we are going to put that into a calculator so we would do pi times 2 (radius of circle)^2 which is 12.57 and we would subtract 16 by 12.57 which is 3.43
Answer:
3.44 units^2
Step-by-step explanation:
Area of a square = l * w
Area of a circle = 3.14 * r^2
Area of semicircle = 3.14 * r^2 * 1/2
Area of shaded region: Area of square - Area of 2 semicircles
Area of square => 4 * 4 = 16
Area of both semicircles => (3.14 * r^2 * 1/2)*2 = 12.56
16 - 12.56 = 3.44
3.44 units^2 is the answer

Write a introduction paragraph on Cycling ( English)
Answer:
Let's look back at the history of the world and reflect on some of the great new methods of transportation that have been invented. There were cars, motorbikes, cycles, carriages, trains, boats, carts and horseback. Cycles have by far been the most economical and productive to use. The first was made in 1817 by Karl von Drais. Since then, many improvements and changes have been made to the original design, like making equally sized wheels, adding rubber tires, etc.
Answer:
Cycling, also called bicycling or biking, is the use of bicycles for transport, recreation, exercise or sport. People engaged in cycling are referred to as "cyclists", "bicyclists", or "bikers". Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadracycles, recumbent and similar human-powered vehicles (HPVs).
Bicycles were introduced in the 19th century and now number approximately one billion worldwide. They are the principal means of transportation in many parts of the world.
Cycling is widely regarded as a very effective and efficient mode of transportation optimal for short to moderate distances.
Bicycles provide numerous benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a reduced consumption of fossil fuels, less air or noise pollution, and much reduced traffic congestion. These lead to less financial cost to the user as well as to society at large (negligible damage to roads, less road area required). By fitting bicycle racks on the front of buses, transit agencies can significantly increase the areas they can serve
In addition, cycling provides a variety of health benefits. The World Health Organization (WHO) states that cycling can reduce the risk of cancers, heart disease, and diabetes that are prevalent in sedentary lifestyles. Cycling on stationary bikes have also been used as part of rehabilitation for lower limb injuries, particularly after hip surgery. Individuals who cycle regularly have also reported mental health improvements, including less perceived stress and better vitality.
Among the disadvantages of cycling are the requirement of bicycles (excepting tricycles or quadracycles) to be balanced by the rider in order to remain upright, the reduced protection in crashes in comparison to motor vehicles, often longer travel time (except in densely populated areas), vulnerability to weather conditions, difficulty in transporting passengers, and the fact that a basic level of fitness is required for cycling moderate to long distances.

For something like x = 2.5 or x = 2.7, the value of [tex]\lfloor x \rfloor[/tex] will be 2. It doesn't matter that 2.7 is closer to 3 than it is to 2. The interval [tex]2 \le x < 3[/tex] will be entirely on the x axis since we are taking the result of the flooring operation and subtracting off 2. Notice how x = 3 is not included. This is because x = 3 leads to y = 1 instead of y = 0. So we have an open hole at the end of the interval. The same goes for any other piece as well.
