The function for the Pakistani Rupee (y) in terms of UAE Dirhams (x) can be represented as, y = 71.59 x.

A function is defined as a relation from a set A to a set B for which an element in set A maps to one and only one image in set B.

Usually the set A consists of the independent variable and set B consists of dependent variable.

We have to find a function relating the conversion of Pakistani rupees and UAE dirhams.

Let y denotes Pakistani Rupees and x denotes the UAE dirhams.

We know that,

1 UAE dirham = 71.59 Pakistani Rupees

So,

2 dirhams = 2 × 71.59 = 143.18 rupees

In this way,

x dirhams = 71.59 x rupees

So, we can write this as,

y = 71.59 x

Hence the required function is y = 71.59 x.

To solve the equation cos²x + sin x = 1, we can use the trigonometric identity cos²x = 1 - sin²x. By substituting this identity into the equation, we get:

1 - sin²x + sin x = 1

Combining like terms, we get:

1 - sin²x = 0

Solving for sin x, we get:

sin x = 1

However, the sine function has a range of [-1, 1], so the only solution in the interval [0, 2π] is sin x = 1, which corresponds to x = π/2. So the solution to the equation cos²x + sin x = 1 in the interval [0, 2π] is x = π/2.

Bill should use the "Print It"company.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

To determine which company Bill should use, you need to calculate the total cost of each option and compare them.

For "Print It," the total cost would be :

= 30 x $21.50

Apply the multiplication operation, and we get

= $645.00

For "Top Print," the total cost would be :

= $70.00 + (30 x $18.00)

= $690.00

Since the cost of "Print It" is lower than "Top Print," Bill should use "Print It" as it would be a more cost-effective option for him.

Thus, he should use the "Print It"company.

The length of the diagonal of an isosceles trapezoid is 2.83 cm

An isosceles trapezoid is a quadrilateral with two parallel sides and two non-parallel sides of different lengths.

In this case, the non-parallel sides are the bases, which are 3cm and 7cm long. The height is the perpendicular distance between the two bases and is given as 4cm. To find the length of the diagonals, we can use the Pythagorean theorem, which states that the sum of the squares of the two shorter sides of a right triangle is equal to the square of the hypotenuse (the longest side).

In an isosceles trapezoid, the diagonals are equal in length and bisect each other. Let's call the length of the diagonal d. We can draw a right triangle with one leg being half of the trapezoid's height (2cm), the other leg being half of the difference between the two bases (2cm), and the hypotenuse being the length of the diagonal d. Using the Pythagorean theorem, we get:

(2cm)² + (2cm)² = d²

4cm² + 4cm² = d²

8cm² = d²

d = √(8cm²)

d = 2√(2)cm

d = 2.83cm

The value of x is 80 degrees.

The correct answer is an option (A)

Consider the following figure.

Let us assume that the upper triangle be ABC and the lower triangle be NMC.

We can observe that both the triangles are isosceles triangles, because in both the triangles two sides are congruent.

Consider triangle ABC.

As the triangle is isosceles triangle, from the definition of  isosceles triangle ∠A = ∠B

So, ∠A = 65°

We know that the sum of all the angles of triangle is 180°

⇒ ∠A + ∠B + ∠C = 180°

⇒ ∠C = 180° - (65° + 65°)

⇒ ∠C = 180° - 130°

⇒ ∠C = 50°

We can observe that ∠ACB and ∠MCN are opposite angles.

So,  ∠MCN = 50°

Also, triangle MNC is also an isosceles triangle.

so, ∠C = ∠N

⇒∠N = 50°

We know that the sum of all the angles of triangle is 180°

⇒ ∠M + ∠N + ∠C = 180°

⇒ ∠M = 180° - (50° + 50°)

⇒ ∠M = 180° - 100°

⇒ ∠M = 80°

Answer:1024 grid squares

Step-by-step explanation:

Let's call the side length of the original piece of graph paper "x".

Since, side length of the cut out square is then (x-2) because the cut out square has to have an integer number of grid squares, and each side of the square would take up 2 grid squares on the graph paper.

The number of grid squares in the cut out square is then (x-2)^2.

The number of grid squares left on the graph paper is 124, so we have:

x^2 - (x-2)^2 = 124

Expanding the right side:

x^2 - x^2 + 4x - 4 = 124

Simplifying:

4x = 128

therefore:

x = 32

therefore original graph paper contains 32 grids i.e 32^2 = 1024

Answer:

  any of {128, 133, 140, 160, 224, 320, 380, 700, 1024}

  1024 if the original grid was square

Step-by-step explanation:

You want to know how many grid squares are on a piece of graph paper if a square number of grid squares can be cut from it to leave 124 grid squares.

If the graph is square to begin with, a square of x² can be removed from its size (x+a)² to leave 124 squares. That is ...

  (x +a)² -x² = 124

  (a)(2x+a) = 124

The factor pairs of 124 are ...

  124 = 1·124 = 2·62 = 4·31

Of these, only 2 and 62 differ by an even number, so we have a=2 and x=30.

The graph paper could be 32 units square originally, having 1024 grid squares.

There is nothing in the problem statement that requires the original graph paper be square. If it is not necessarily square, there are 13 possible shapes it could be. Those have 9 different possibilities for numbers of grid squares.

The graph paper could have originally had this number of grid squares:

The equation of the total bill with x number of refills is y = 5 + x and the refills if the bill is $9 is 4.

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13.

Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero.

Let us consider the number of times we refill = x.

For every refill the cost will be = 1(x) = x.

Then, a basket of fries for $5, and each refill basket of fries is only $1 is:

y = 5 + x

The equation of the total bill with x number of refills is y = 5 + x.

The graph of the equation is obtained by substituting different values of x.

For x = 1:

y = 5 + 1 = 6

Similarly, x = 2:

y = 5 + 2 = 7

If the bill is $9 then,

y = 5 + x

9 = 5 + x

9 - 5 = x

x = 4

When the water cooler is completely full, there are approximately 143.52 gallons of water in it.

To calculate the number of gallons of water in the water cooler when it is completely full, we can use the formula for the volume of a cylinder, which is:

Volume = π * (radius)^2 * height

where radius is half of the diameter, and π is the constant pi.

In this case, the diameter of the water cooler is 3.5 feet, so the radius is 1.75 feet. The height of the water cooler is 2 feet. Plugging these values into the formula, we get:

Volume = 3.14 * (1.75)^2 * 2 = 19.18 cubic feet

To convert this volume to gallons, we can multiply it by the conversion factor of 7.48 gallons per cubic foot:

Volume in gallons = 19.18 * 7.48 = 143.52 gallons

In summary, to calculate the number of gallons of water in a cylindrical water cooler, we can use the formula for the volume of a cylinder and then convert the resulting volume from cubic feet to gallons using a conversion factor.

In this case, we needed to use the diameter and height of the water cooler, along with the constant pi and the conversion factor of gallons per cubic foot, to calculate the number of gallons of water in the water cooler when it is completely full.

b) The equation of  parallel  line is y = -2x+6

What is slope ?

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).

a) An equation perpendicular to y= (-1/2)x+4 through the point (-2, -3):

m= -1/2

Slope of perpendicular line is -1/m  = -1/( -1/2) = 2

Slope intercept form:

y=mx+b

Substitute x,y and m values to find b

-3= 2(-2) + b

=> -3 = -4 + b

=> b= -3+4 = 1

So the equation of  perpendicular line is y=2x+1

b)  An equation through the point  (1,4)  parallel to  y = -2x + 1

Parallel lines will have same slope , m= -2

(x,y) =  (1,4)

The distance travelled by Rahul, if he takes 6 rounds of a square field of side = 120m is 2880 meters.

We are given that Rahul takes 6 rounds of a square field of side length 120m. To find the total distance he travels, we need to calculate the perimeter of the square field and multiply it by the number of rounds.

The perimeter of a square is the sum of the lengths of its four sides. Since the side length of the square field is 120m, the perimeter is:

4 * 120m = 480m

This is the distance Rahul covers in one round around the square field.

To find the total distance he covers in 6 rounds, we multiply the distance covered in one round by the number of rounds:

480m * 6 = 2880m

Answer: [tex]36/\pi[/tex] or approximately 11.4592

Step-by-step explanation:

The distance around a circle equals its circumference.

The circumference equation is: C = 2[tex]\pi[/tex] * r where r = radius.

Now, we know that the distance around the circle is 36 so C = 36

Using the equation, we have 36= 2[tex]\pi[/tex]*r

Now, we solve for r by dividing by 2[tex]\pi[/tex] to both sides.

r = [tex]36/2\pi[/tex] which equals [tex]18/\pi[/tex] which is approximately 5.7296

Now, since radius is half of the diameter, we need to multiply this by 2.
