The area that can be watered by the pipe of length 500 inches is approximately 18.03 square yards, when the length of the pipe is 800 inches the area watered is approximately 46.16 square yards and when the length of pipe is 1300 inches the area watered is approximately 121.89 square yards as calculated by the given function.

A function is defined as a relation between the dependent variable and the independent variable.

The length of the pipe is given by the function L=117.75√A where A is the area of the lawn that can be watered.

Now to calculate the area that can be watered using a particular length of pipe we have to find the inverse of the given function.

Given L=117.75√A

Squaring both sides we get

L²=13865.0625 × A

or , A=L²÷13865.0625

Now given length L=500 inches

Substituting the values we get:

A=(500)²÷13865.0625

A=18.0309...

A≈18.03 square yards

Hence the area that can be watered is approximately 64.68 square yards.

Similarly for length 800 inches

Area watered= (800)²÷13865.0625=46.159 square yards.

≈46.16 square yards

Similarly for length 1300 inches

Area watered=1300²÷13865.0625=121.889 square yards

≈121.89 square yards

Therefore the area that can be watered by the pipe of length 500 inches is approximately 18.03 square yards, when the length of the pipe is 800 inches the area watered is 46.16 square yards and when the length of pipe is 1300 inches the area watered is 121.89 square yards.

Answer:

7 m

Step-by-step explanation:

We are told that;

100 cm = 1 m

Thus; 2.54 cm = 2.54 × 1/100 = 0.0254 m

This means that;

1 inch = 0.0254 m

Thus; 275 inches will give; 275 × 0.0254/1 = 6.985 m

Approximating to the nearest metre gives 7 m

The mathematical expression y(x,t) = Asin(kx)sin(wt) provides a way to describe the behavior of a standing wave in terms of its amplitude, frequency, and location along the string.

At time t=0,

the standing wave can be mathematically expressed as

y(x,0) = Asin(kx)sin(w*0) = Asin(kx)sin(0) = 0.

This means that the displacement of the string is zero at time t=0.

However, it is important to note that this does not mean that the string is not moving at all. Rather, it means that the string is in a state of equilibrium at time t=0, with the maximum transverse displacement being A.

As time progresses, the standing wave will oscillate between the maximum positive and negative transverse displacement values, creating a pattern of nodes (points of zero displacements) and antinodes (points of maximum displacement).

The wave number k and angular frequency w are both constants that are dependent on the physical properties of the string and the conditions under which the wave is being produced.

Answer: 25 + 12.5v ≥ 170

Step-by-step explanation:

We already have the 25 reward points; it also gives the information that she gets 12.5 points for each visit. Because we don't know the amount she has gone to the theater or will go we have to use a variable; 12.5v. When we add them, we get 25 + 12.5v. The inequality we use is ≥ because it says "at least". When this is used that means it has to be equal to or greater and that is why use that sign and get the full equation;

The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Area of regular polygon = 1/2 × apothem × perimeter

perimeter = (s)side length of octagon × (n)number of side.

apothem = s/[2tan(180/n)].

11 = s/[2tan(180/12)]

s = 11 × 2tan15

s = 5.8949

perimeter = 5.8949 × 12 = 70.7388

Area of dodecagon = 1/2 × 11 × 70.7388

Area of dodecagon = 389.0634 in²

Area of pentagon = 1/2 × 5.23 × 7.6

Area of pentagon = 19.874 in²

Therefore, the area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Answer:

Q11:  31 and 44

Q12: -5, 15, -9, 19

Q13: 16

Step-by-step explanation:

Question 10

Let x = smaller part

Let y = larger part

Given sum of parts is 75:

x + y = 75

Given the larger part is 13 more than the smaller part:

y = 13 + x

Substitute y = 13 + x into x + y = 75 and solve for x:

⇒ x + 13 + x = 75

⇒ 2x + 13 = 75

⇒ 2x = 62

⇒ x = 31

Substitute found value of x into y = 13 + x and solve for y:

⇒ y = 13 + 31

⇒ y = 44

Therefore, the smaller part is 31 and the larger part is 44

Question 11

Let x = first number

Let y = second number

Let z = third number

Let w = fourth number

Given the first is 20 less than the second:

x = y - 20

⇒ y = x + 20

Given the third is 1 more than twice the first:

z = 2x + 1

Given the fourth is 4 more than the second:

w = y + 4

Given the sum of the first and second equals the sum of the third and fourth numbers:

x + y = z + w

Substitute the first 3 equations into x + y = z + w  and rearrange to make y the subject:

⇒ (y - 20) + y = (2x + 1) + (y + 4)

⇒ 2y - 20 = 2x + y + 5

⇒ y = 2x + 25

Rearrange x = y - 20 to make y the subject:

x = y - 20

⇒ y = x + 20

Now equate the equations and solve for x:

⇒ x + 25 = 20

⇒ x = -5

Now we have found the value of x, substitute into z = 2x + 1 to find z:

⇒ z = 2(-5)+ 1

⇒ z = -9

and substitute the value of x into y = x + 20 to find y:

⇒ y = -5 + 20

⇒ y = 15

finally substitute the value of y into w = y + 4 to find w:

⇒ w = 15 + 4

⇒ w = 19

Therefore,

Question 12

Let x = unknown number

Given one quarter of a number is being increased by one half of the same number is 12:

\(\implies \dfrac14x+\dfrac12x=12\)

\(\implies \dfrac34x=12\)

\(\implies 3x=12 \times 4\)

\(\implies 3x=48\)

\(\implies x=16\)

After solving the given function for x = 3, the resultant answer is (A) -28.

The exact same number of elements from Y is assigned to each element of X via a mathematical function from a set X to a set Y.

The function's domain and codomain are respectively referred to as the sets X and Y as a whole.

A function is a relationship between a number of inputs and outputs.

Simply described, a function is an association between inputs in which each input is coupled to exactly one output.

So, we have the function:

(x) = −5x² − x + 20

Now, calculate to find the value when: x = 3

Given that, we must determine the value of the function at x = 3.

Set x = 3 in the provided function, f(x)

f(3) = −5(3)² − x + 20

f(x) = -45 - 3 + 20 = -28

Therefore, after solving the given function for x = 3, the resultant answer is (A) -28.

Answer: -4 and 9

Step-by-step explanation:

Our function is a parabola, therefore, it has only one critical point which is its vertex. Since the coefficient of the squared term is negative, the vertex is the maximum point.The critical points of a function are given by the zeros of the first derivative. The first derivative of our function is:

The solutions for the following equation are the critical points of the original function:

The maximum point happens at x = - 3.

To find the corresponding value, we just have to evaluate x = - 3 into our function:

The maximum value of the function is 1, and it occurs at x = - 3.

Answer: The function has a maximum value

               The function's maximum value is 1

               The function's maximum value occurs at x=-3

Step-by-step explanation:

Given equation: \(g(x) = -3x^ - 18x - 26\)

We shall use the differentiation method to find the answer.

Differentiating the equation, we get   \(g'(x) = - 6x - 18\)

equating g'(x) = 0,

\(-6x - 18 = 0\\-6x = 18 \\x = -3\)

Hence the minimum/ maximum value of the function lies in x = -3

on equating x>-3, g'(x) is negative

on equating x<-3, g'(x) is positive

this proves that first, the function was increasing and after x = -3, the function started to decrease hence at x=-3, the function g(x) was at its maximum value

The function's maximum value at x=-3 is

\(g(x) = -3x^2 - 18x - 26\\g(-3) = -3(-3)^2 - 18(-3) - 26\\g(-3) = -3(9) +54 -26\\g(-3) = 54 - 27 -26\\g(-3) = 1\)

Using the properties of parallelograms and the given information, we proved that BAEC is equal to FABC. We utilized angle-angle similarity and the proportional relationships of corresponding sides in similar triangles to establish the equality.

To prove that BAEC = FABC, we will use the properties of parallelograms and the given information.

Given:

ABCD is a parallelogram.

BE is parallel to CD.

BF is parallel to AD.

To prove:

BAEC = FABC

Proof:

Since ABCD is a parallelogram, we know that opposite sides are parallel and equal in length. Let's denote the length of AB as a, BC as b, AD as c, and CD as d.

Since BE is parallel to CD and AD is parallel to BF, we have angle ABE = angle CDF and angle ADB = angle BFD.

By alternate interior angles, angle CDF = angle FAB.

Now, we have two pairs of congruent angles: angle ABE = angle CDF and angle ADB = angle BFD.

Using angle-angle similarity, we can conclude that triangle ABE is similar to triangle CDF and triangle ADB is similar to triangle BFD.

As the corresponding sides of similar triangles are proportional, we have the following ratios:

AB/CD = AE/CF (from triangle ABE and triangle CDF similarity)

AD/BC = BD/CF (from triangle ADB and triangle BFD similarity)

Cross-multiplying the ratios, we get:

AB * CF = CD * AE (equation 1)

AD * CF = BC * BD (equation 2)

Adding equation 1 and equation 2, we have:

AB * CF + AD * CF = CD * AE + BC * BD

Factoring out CF, we get:

CF * (AB + AD) = CD * AE + BC * BD

Since AB + AD = CD (opposite sides of a parallelogram are equal), we have:

CF * CD = CD * AE + BC * BD

Simplifying, we get:

CF = AE + BC

Therefore, we have shown that BAEC = FABC.
