the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.with  the sum of the first n terms of the arithmetic series formula we are able to solve it

what is arithmetic series  ?

An arithmetic series is a series of numbers in which each term is obtained by adding a fixed number to the preceding term (known as the common difference). The sum of the terms in an arithmetic series can be found by multiplying the average of the first and last

In the given question,

We know that the first term of the arithmetic series is given by (2t+1) and the common difference is 3. Therefore, the nth term can be written as:

aₙ = a₁ + (n-1)d

(14r - 5) = (2t + 1) + (n-1)3

14r - 5 = 2t + 1 + 3n - 3

14r - 4 = 2t + 3n

7r - 2 = t + (3/2)n --------(1)

Now, we need to find the values of p, q, and r for the sum of the first n terms of the series, which is given by:

Sₙ = (n/2)[2a₁ + (n-1)d]

Sₙ = (n/2)[2(2t+1) + (n-1)3]

Sₙ = n(3n+4t+2)/2

We can simplify this expression by factoring out a 2 from the numerator:

Sₙ = n(3n+4t+2)/2 = (2n/2)(3n+4t+2)/2

Sₙ = (n/2)(3n+4t+2) = (3/2)n² + 2tn + n

Now, we need to write this expression in the form p(qt-1). To do this, we need to factor out (3/2):

Sₙ = (3/2)(n² + 4/3 tₙ + 2/3 n)

Sₙ = (3/2)[n² + 4/3 tₙ + (2/9)(3n)]

Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n]

Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/9)t² - (4/3)tₙ + (4/3)tₙ]

Sₙ= (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/3)tₙ]

Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)(3t*n)]

Now we can see that p=3/2, q=3t, and r=2/9. Therefore, the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.

what is the largest of 3 consecutive positive integers if the product of the two is smaller integers is 8 more times the largest integer

Answers

The three successive positive numbers are 3, 4, and 5.

The largest of these 5.

What are integers?

Integers are made up of zeros, natural numbers, and their additive inverses. Except for the fractional part, it can be represented on a number line.

Let's call the smallest of three successive positive numbers x. The following two consecutive integers would then be x + 1 and x + 2.

The product of the two smaller integers (x and x + 1) is eight times that of the largest integer (x + 2). This can be written as an equation:

x(x + 1) = 8 + (x + 2)

By enlarging and simplifying the left side, we get:

[tex]x^2 + x = x + 10[/tex]

When we subtract x and 10 from both sides, we get:

[tex]x^2 - 9 = 0[/tex]

After factoring in, we get:

(x - 3)(x + 3) = 0

As a result, x = 3 or x = -3. We can disregard the negative solution because we're seeking positive integers and infer that x = 3.

As a result, the three successive positive numbers are 3, 4, and 5.

The hypotenuse of a right triangle is 1 cm longer than the longest leg. The shorter leg is 7 cm shorter than the longest leg. Find the dimensions of the triangle.

Answers

Answer:

The hypotenuse is 13 cm

The longest leg is 12 cm

The shortest leg is 5 cm

Step-by-step explanation:

Given:

A right triangle

Let's assume, that the longest leg is x, the shortest leg is y and the hypotenuse is z

Let's write 2 equations according to the given information and put them into a system (use the Pythagorean theorem):

[tex]z = \sqrt{ {x}^{2} + {y}^{2} } [/tex]

{(x^2 + y^2) = x + 1,

{x - y = 7;

Let's make x the subject from the 2nd equation:

x = 7 + y

Replace x in the 1st equation with its value from the 2nd one:

[tex] \sqrt{( {7 + y)}^{2} + {y}^{2} } = (7 + y) + 1[/tex]

[tex] \sqrt{49 + 14y + {2y}^{2} } = 8 + y[/tex]

Square both sides of the equation:

[tex]2 {y}^{2} + 14y + 49 = {(8 + y)}^{2} [/tex]

[tex]2 {y}^{2} + 14y + 49 = 64 + 16y + {y}^{2} [/tex]

Move the expression to the left and collect like-terms:

[tex] {y}^{2} - 2y - 15 = 0[/tex]

a = 1, b = -2, c = -15

Solve this quadratic equation:

[tex]d = {b}^{2} - 4ac = ({ - 2})^{2} - 4 \times 1 \times ( - 15) = 64 > 0[/tex]

[tex]y1 = \frac{ - b - \sqrt{d} }{2a} = \frac{2 - 8}{2 \times 1} = \frac{ - 6}{2} = - 3[/tex]

y must be a natural number, since the length of a triangle's side cannot have negative units

[tex]y2 = \frac{ - b + \sqrt{d} }{2a} = \frac{2 + 8}{2 \times 1} = 5[/tex]

We found the length of the shortest leg

Now, we can find the rest of the dimensions:

x = 7 + 5 = 12

[tex]z = \sqrt{ {12}^{2} + {5}^{2} } = \sqrt{144 + 25} = \sqrt{169} = 13[/tex]

A Ferris wheel is 30 meters in diameter and boarded from a platform that is 2 meters above the ground. The six o'clock position on the Ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 10 minutes. The function h(t) gives a person's height in meters above the ground t minutes after the wheel begins to turn. a. Find the amplitude, midline, and period of h(t). Amplitude: meters Period: Midline: h - minutes meters b. How high off the ground is a person after 5 minutes? meters​

Answers

Answer:

a. The Ferris wheel has a diameter of 30 meters, which means the radius is 15 meters. Since the wheel is boarded from a platform that is 2 meters above the ground, the center of the Ferris wheel is 2 + 15 = 17 meters above the ground.

The function h(t) gives a person's height in meters above the ground t minutes after the wheel begins to turn. Since the Ferris wheel completes one revolution in 10 minutes, the period of h(t) is 10 minutes.

The midline is the average value of the function h(t) over one period, and it is equal to the vertical displacement of the graph from the x-axis. Since the center of the Ferris wheel is 17 meters above the ground, the midline is h = 17 meters.

The amplitude of the function h(t) is the distance between the midline and the maximum or minimum value of the function. The maximum height a person can reach on the Ferris wheel is when they are at the very top of the wheel, which is 17 + 15 = 32 meters above the ground. The minimum height a person can reach on the Ferris wheel is when they are at the very bottom of the wheel, which is 17 - 15 = 2 meters above the ground. So the amplitude of h(t) is 15 meters.

Therefore, the amplitude is 15 meters, the midline is h = 17 meters, and the period is 10 minutes.

b. To find the height of a person after 5 minutes, we can plug t = 5 into the function h(t):

h(5) = 15 sin(2π/10 * 5) + 17

h(5) = 15 sin(π) + 17

h(5) = 2 meters

Therefore, a person is 2 meters above the ground after 5 minutes on the Ferris wheel.

What is the Continuous Compound Interest ?

Recurring interest is interest calculated on principal plus all interest and other interest. The idea is that lenders always receive interest, not individually at specific times.

The formula for continuous compound interest :

  A=    Peˣⁿ                          

Where,

A =Amount of money  after a certain amount of time

P= principal or the amount of money you start with

e =Napier's number, which is approximately 2.7183

x =Interest rate

n =Amount of time in years.

Use the continuous compound interest formula :

Given  P= 2658

x =9% =   = 0.09

n = 15

e = 2.7183

By using

A=    Peˣⁿ  

A= (2658)(2.7183)⁰°⁰⁹¹⁵

A =10,253 (approximately)

Hence, the value of account balance after 15 years is approximately $10,253

Step-by-step explanation:

Final answer:

The midpoint of the line segment AB with coordinates A = (-3, -1) and B = (-7, -7) is (-5, -4).

Explanation:

To find the midpoint of a line segment AB, we can use the midpoint formula. The midpoint formula states that the x-coordinate of the midpoint is the average of the x-coordinates of A and B, and the y-coordinate of the midpoint is the average of the y-coordinates of A and B.

Given A = (-3, -1) and B = (-7, -7), we can use the midpoint formula as follows:

x-coordinate of M = (x-coordinate of A + x-coordinate of B) / 2 = (-3 + -7) / 2 = -5y-coordinate of M = (y-coordinate of A + y-coordinate of B) / 2 = (-1 + -7) / 2 = -4

a certain water filtration system can remove 70% of the contaminants each time a simple of water is passed through it. if the water is passed through the system four times, what percent of the original contaminants will be removed from the water sample?

Answers

after four passes through the filtration system, 99.19% of the original contaminants will have been removed from the water sample

How to solve the question?

Each time the water passes through the filtration system, 70% of the contaminants are removed, which means that 30% of the contaminants remain in the water. After the first pass, 30% of the original contaminants are left in the water. After the second pass, 30% of the remaining 30% is left, which is equivalent to 9% of the original contaminants. After the third pass, 30% of the remaining 9% is left, which is equivalent to 2.7% of the original contaminants. Finally, after the fourth pass, 30% of the remaining 2.7% is left, which is equivalent to 0.81% of the original contaminants.

Therefore, after four passes through the filtration system, 99.19% of the original contaminants will have been removed from the water sample. This calculation can be obtained by subtracting the final percentage of contaminants left (0.81%) from 100%.

It's important to note that while passing the water through the filtration system multiple times increases the overall percentage of contaminants removed, it's not a substitute for regular maintenance and replacement of the filtration system's components. Over time, the filtration system's effectiveness can diminish, and it's crucial to follow the manufacturer's instructions for proper maintenance and replacement to ensure that the system continues to function optimally.

Step-by-step explanation:

If a continuous random variable X is normally distributed with mean μ and variance σ², it is written as:

[tex]\boxed{X \sim\text{N}(\mu,\sigma^2)}[/tex]

Given:

Mean μ = 100 mg/dlStandard deviation σ = 10 mg/dl

Therefore, if the blood sugar levels are normally distributed:

[tex]\boxed{X \sim\text{N}(100,10^2)}[/tex]

where X is the blood sugar level in milligrams per deciliter.

Converting to the Z distribution:

[tex]\boxed{\textsf{If }\: X \sim\textsf{N}(\mu,\sigma^2)\:\textsf{ then }\: \dfrac{X-\mu}{\sigma}=Z, \quad \textsf{where }\: Z \sim \textsf{N}(0,1)}[/tex]

Write the equation of
the circle with diameter
endpoints of (-6, 3) and
(-14, 13).

Answers

The midpoint of the line segment connecting the endpoints of the diameter is the center of the circle. We can find the midpoint by averaging the coordinates of the endpoints:

$\sf\implies\:Midpoint\:=\:\left(\frac{-6\:-\:14}{2},\:\frac{3\:+\:13}{2}\right)\:=\:(-10,\:8)$

The radius of the circle is half the length of the diameter, which we can find using the distance formula:

$\sf\implies\:Radius\:=\:\frac{\sqrt{(-6\:-\:(-14))^2\:+\:(3\:-\:13)^2}}{2}\:=\:\frac{\sqrt{160}}{2}\:=\:4\sqrt{10}$

Thus, the equation of the circle is

$\sf\implies\:(x\:+\:10)^2\:+\:(y\:-\:8)^2\:=\:(4\sqrt{10})^2$

Simplifying and rearranging, we get:

$\sf\implies\red\bigstar\:(x\:+\:10)^2\:+\:(y\:-\:8)^2\:=\:160$

what is the area of this shape

Answers

Step-by-step explanation:

Assuming   18 cm and 12 cm sides are parallel ( you are not told this) , this is just a trapezoid

  area = height * averge of bases = 7 * ( 12+18)/2 = 105 cm^2

Answer:

Step-by-step explanation:

The area of a rectangular field is equal to the area of a square. The length of the
rectangular field is 4 times the width. The cost of rope per metre is Tk 7. The
cost of the rope to make fence twice around the field is Tk 5600.
a) What will be the perimeter of the rectangular field?
b)
If you sow a papaya plant in every 4 m2 area how many papaya plants will
be needed?

Answers

Let's assume that the area of the rectangular field is x square meters, and the width of the field is y meters. Then we know that:

x = y * 4 (since the length of the rectangular field is 4 times the width)

And we also know that the area of the rectangular field is equal to the area of a square. Therefore:

x = y^2

Combining these two equations, we get:

y^2 = y * 4

y = 4 meters

So the width of the rectangular field is 4 meters. Using this, we can find the length:

x = y * 4 = 4 * 4 = 16 square meters

Now, to find the perimeter of the rectangular field:

Perimeter = 2 * (length + width) = 2 * (16 + 4) = 40 meters

Therefore, the perimeter of the rectangular field is 40 meters.

Next, we need to find the number of papaya plants that can be sown in the area of the field. The total area of the field is 16 square meters. If one papaya plant is sown in every 4 square meters, then the number of plants required would be:

Number of plants = Total area / Area per plant

Number of plants = 16 / 4 = 4 plants

Therefore, 4 papaya plants can be sown in the rectangular field.

Answers

Answer:

Step-by-step explanation:

A. The individual events are dependent. The probability of the combined event is:

The probability of drawing a red piece of candy on the first draw is 10/51. Since we do not replace the candy after the first draw, the probability of drawing another red piece of candy on the second draw depends on what happened on the first draw. If a red piece of candy was drawn on the first draw, then there are 9 red pieces of candy left out of 50 total pieces of candy for the second draw. If a non-red piece of candy was drawn on the first draw, then there are still 10 red pieces of candy left out of 50 total pieces of candy for the second draw. Therefore, the probability of drawing two red pieces of candy in a row is:

(10/51) x (9/50) + (41/51) x (10/50) = 0.0698

Rounded to three decimal places, the probability of the combined event is 0.070.

Solve the following maximization problem graphically.

P(x,y)=82x+50y
subject to
2x+2y≥10
3x+6y≤54
x≥0
y≥0
x≤10
y≤8

Answers

Answer:

Step-by-step explanation:

To solve the maximization problem graphically, we first need to graph the constraints and find the feasible region. Then we can find the corner points of the feasible region and evaluate the objective function at each corner point to find the maximum value.

Graphing the constraint 2x + 2y ≥ 10, we get the following line:

2x + 2y = 10

y = 5 - x

Graphing the constraint 3x + 6y ≤ 54, we get the following line:

3x + 6y = 54

y = 9 - 0.5x

We also need to graph the non-negative constraints x ≥ 0 and y ≥ 0, as well as the constraints x ≤ 10 and y ≤ 8, which limit the values of x and y.

The feasible region is the shaded region in the graph. To find the corner points of the feasible region, we can find the points where the lines intersect. There are four corner points: (0, 5), (0, 9), (6, 4), and (10, 0).

Now we can evaluate the objective function at each corner point to find the maximum value:

P(0, 5) = 82(0) + 50(5) = 250

P(0, 9) = 82(0) + 50(9) = 450

P(6, 4) = 82(6) + 50(4) = 652

P(10, 0) = 82(10) + 50(0) = 820

Therefore, the maximum value of the objective function is 820, which occurs at the point (10, 0).

Therefore, the maximum value of P(x,y)=82x+50y subject to the given constraints is 820, and it occurs at the point (10,0).

What are vertically opposite angles?

Vertically opposite angles are a pair of angles formed by the intersection of two straight lines. When two lines intersect at a point, four angles are formed, and the angles that are opposite each other and not adjacent are called vertically opposite angles. Vertically opposite angles are always equal in measure, which means that they have the same angle degree or radian measure.

We know that the interior angle is vertically opposite to 39 degrees and the exterior angle is equal to the sum of the opposite interior angles.

Hence;

55 + 39 = 94 degrees

Perimeter and area of

Answers

The perimeter and area of the rectangle are 14xy² + 20x² units and  70x³y² square units respectively.

The perimeter and area of the triangle are respectively.

The area of the trapezoid is 18x³y square units.

How to calculate the perimeter of a rectangle?

In Mathematics and Geometry, the perimeter of a rectangle can be calculated by using this mathematical expression;

P = 2(L + B)

Where:

P represent the perimeter of a rectangle.B represent the breadth of a rectangle.L represent the length of a rectangle.

By substituting the given side lengths into the formula for the perimeter of a perimeter of a rectangle, we have the following;

P = 2(L + B)

P = 2(7xy² + 10x²)

P = 14xy² + 20x² units.

For the area of rectangle, we have:

Area = LB

Area = 7xy² × 10x²

Area = 70x³y² square units.

For the perimeter and area of the triangle, we have:

Perimeter = 2a³b + 6a³b + 4ab = 8a³b + 4ab units.

Area = 1/2 × base × height

Area = 1/2 × 4ab × 2a³b

Area = 4a⁴b² square units.

For the area of trapezoid, we have;

Area of trapezoid, A = ½ × (a + b) × h

Area of trapezoid, A = ½ × (4xy + 8xy) × 3x²

Area of trapezoid, A = 6xy × 3x²

Area of trapezoid, A = 18x³y square units.
