Answer:

Step-by-step explanation:To find the diameter of a circular field given its circumference, we can use the formula:

Circumference = π * Diameter

In this case, the circumference is given as 132m. Plugging in the values into the formula, we have:

132m = π * Diameter

To solve for the diameter, we need to isolate it on one side of the equation. We can divide both sides of the equation by π:

132m / π = Diameter

Using a calculator, we can approximate the value of π as 3.14159. Plugging in this value, we have:

132m / 3.14159 ≈ Diameter

Simplifying the division, we get:

Diameter ≈ 42m

Therefore, the diameter of the circular field is approximately 42 meters

To determine whether the given differential equation is exact, we need to check if it satisfies the condition:

∂M/∂y = ∂N/∂x

where M and N are the coefficients of dy and dx, respectively, in the differential equation:

(2sin(x)cos(y) − 2y^2)dy - (xsin^2(y) - 4x^2)dx = 0

Now, let's find the partial derivatives:

∂M/∂y = 2cos(x)cos(y) - 4y

∂N/∂x = -sin^2(y) - 8x

The equation is exact if ∂M/∂y = ∂N/∂x. Let's check:

2cos(x)cos(y) - 4y = -sin^2(y) - 8x

Rearranging the equation, we get:

sin^2(y) - 2cos(x)cos(y) - 8x + 4y = 0

Since ∂M/∂y = ∂N/∂x, the given differential equation is exact.

To solve the exact differential equation, we need to find a potential function φ(x, y) such that:

∂φ/∂x = M

∂φ/∂y = N

Integrating M with respect to x, we get:

φ(x, y) = ∫(2sin(x)cos(y) - 2y^2)dx

        = 2∫sin(x)cos(y)dx - 2∫y^2dx

        = -2cos(x)cos(y) - 2xy^2 + g(y)

Here, g(y) is the constant of integration with respect to x.

Next, we differentiate φ(x, y) partially with respect to y and equate it to N:

∂φ/∂y = N

-2sin(x)sin(y) - 4xy + g'(y) = -sin^2(y) - 8x

From this equation, we can equate the coefficients of the terms involving y:

-2sin(x)sin(y) - 4xy = -8x

-2sin(x)sin(y) - 4xy + 8x = 0

Comparing the coefficients, we have:

g'(y) = 0

Integrating g'(y), we obtain:

g(y) = c

Here, c is the constant of integration with respect to y.

Finally, the potential function φ(x, y) becomes:

φ(x, y) = -2cos(x)cos(y) - 2xy^2 + c

Therefore, the solution to the given exact differential equation is φ(x, y) = -2cos(x)cos(y) - 2xy^2 + c, where c is an arbitrary constant.

The length of the arc is approximately 61.68 cm, and the area of the sector is approximately 1509.16 cm^2.

To find the length of the arc and the area of the sector, we can use the formulas related to circles and angles.

Length of the arc:

The formula to find the length of an arc in a circle is given by:

Arc Length = (angle / 360°) × (2πr)

In this case, the angle is 72°, and the radius is 49 cm. Substituting these values into the formula, we get:

Arc Length = (72° / 360°) × (2π × 49 cm)

Arc Length = (1/5) × (2π × 49 cm)

Arc Length = (2/5) × (π × 49 cm)

Arc Length = (2/5) × (π × 49 cm)

Arc Length ≈ 61.68 cm (rounded to the nearest hundredth)

Therefore, the length of the arc is approximately 61.68 cm.

Area of the sector:

To calculate the area of the sector, we need to use the formula:

Sector Area = (θ / 360°) × (π × r^2)

where θ is the central angle in degrees and r is the radius of the sector.

In this case, the central angle is 72° and the radius is 49 cm. Plugging these values into the formula, we have:

Sector Area = (72° / 360°) × (π × (49 cm)^2)

= (1/5) × (π × 2401 cm^2)

≈ (1/5) × (3.14159 × 2401 cm^2)

≈ (1/5) × 7545.8 cm^2

≈ 1509.16 cm^2

Therefore, the area of the sector is approximately 1509.16 cm^2.

Answer:

Step-by-step explanation:

You want a series of functions and their transformations that will develop a graph of a block capital letter "M", using trig functions.

The block letter M consists mainly of straight lines. To approximate a straight line, we have elected to use the portion of the sine function in the interval [-π/3, π/3] where it is approximately straight, but shows a hint of the sine function.

First, we created a function that moves that segment of the sine function so it is defined between the points (0, 0) and (1, 1). This makes scaling relatively easy.

Then, we created a function that draws that segment between coordinates (a, b) and (c, d).

We used this second function to draw segments between the points we chose for the outline of the left half of the letter.

Finally, we created the right half of the letter by reflecting those functions over the vertical line of symmetry (at x = 4.7). The end result is shown in the first attachment. The function and segment definitions not shown in the first attachment are shown in the second attachment. The f( ) in the Reflection section fills in the horizontal segment between the two halves of the letter.

Appending this identifier to the Desmos URL will give you the graph and function definitions we show here. This should eliminate the need to type them, if the result here is suitable.

We have used 13 function definitions that need to be changed if you desire to move the letter to different coordinates or scale it. You could combine these into two piecewise functions (one for the top, one for the bottom), so that translation or scaling could be done more easily.

The value of side length x and y in the right triangle is 5.7 and 9.4 respectively.

The figure in the image is a right triangle.

Angle G = 59 degree

Hypotenuse = 11

Adjacent to angle G = x

Opposite to angle G = y

To solve for the missing side length x and y, we use the trigonometric ratio.

Note that:

Sine = opposite / hypotensue

Cosine = adjacent / hypotensue

Solving for x:

cos( G ) = adjacent / hypotensue

Plug in the values:

cos( 59 ) = x / 11

Cross multiply

x = cos( 59 ) × 11

x = 5.7 units

Solving for y:

sin( G ) = opposite / hypotensue

Plug in the values:

sin( 59 ) = y / 11

Cross multiply

y = sin( 59 ) × 11

y = 9.4 units

Therefore, the value of y is approximately 9.4 units.

Answer: Therefore, the price of a wrap is Rs 92.2 and the price of a milkshake is Rs (92.2 + 7) = 99.2.

Step-by-step explanation:

Let's assume the price of a wrap is x (in Rs).

According to the given information, a milkshake costs Rs 7 more than a wrap. So, the price of a milkshake would be x + 7 (in Rs).

The group buys 8 milkshakes and 2 wraps. Since they bought 8 milkshakes, the total cost of milkshakes would be 8 * (x + 7) = 8x + 56 (in Rs).

Similarly, the total cost of wraps would be 2x (in Rs).

The total cost for the lunch is given as Rs 978.

So, we can set up the equation:

Total cost of milkshakes + Total cost of wraps = Total cost of lunch

(8x + 56) + (2x) = 978

Combining like terms:

10x + 56 = 978

Subtracting 56 from both sides:

10x = 922

Dividing both sides by 10:

x = 92.2

Using substitution method, the solution to the simultaneous equations are;

1) x = 4, y = 2

2) x = 2, y = 4.

To solve the given simultaneous equations:

We can use substitution or elimination method. Let's use the substitution method:

From equation 2), we can express x in terms of y:

x = 6 - y

Substituting this value of x into equation 1):

[tex]2(6 - y)^2 - 5(6 - y)y + 2y^2 = 0[/tex]

Expanding and simplifying the equation:

[tex]2(36 - 12y + y^2) - 30y + 5y^2 + 2y^2 = 0\\72 - 24y + 2y^2 - 30y + 5y^2 + 2y^2 = 0\\9y^2 - 54y + 72 = 0[/tex]

Dividing the equation by 9 to simplify it further:

[tex]y^2 - 6y + 8 = 0[/tex]

Factoring the quadratic equation:

(y - 2)(y - 4) = 0

Setting each factor to zero:

y - 2 = 0 ;   y = 2

y - 4 = 0  ;   y = 4

Substituting these values of y back into equation 2) to find the corresponding values of x:

For y = 2:

x = 6 - y = 6 - 2 = 4

So, one solution is x = 4, y = 2.

For y = 4:

The linear equation satisfying the given condition is,

[tex]x=t+15[/tex]

where x is Ravi's age and t is the number of years

(after 10 years (t=10) his age becomes 25)

Step-by-step explanation:

Let x be Ravi's age

Now, his  current age is unknown, but if you add 10 to it, then it becomes 25, so

x + 10 =25

so, his current age is x = 25 =10

x = 15

Now, we find the linear equation satisfying the given condition,

Let t be the number of years that have passed since the present time

so, if 0 years have passed, his age will be 15 years

after 1 year, his age will be 16 years

after 10 years, his age will be 25 years and so on

so

[tex]x = t + 15[/tex]

this satisfies the given condition, since if we add ten years i.e t = 10,

then we get 25

The equation is:

Work/explanation:

Here's the linear equation for Ravi's age.

Ravi's age is x.

If you add 10 to x you get x + 10.

That gives 25.

The area of the shaded region when one rectangle is framed within another and the frame has a width of 1 unit, we need to calculate the difference between the areas of the outer rectangle and the inner rectangle.

the dimensions of the outer rectangle as length and width, and the dimensions of the inner rectangle as length' and width'. Based on the information provided, the length and width of the outer rectangle are 5 and 7 units, respectively.

The dimensions of the inner rectangle can be found by subtracting twice the width of the frame (1 unit) from the dimensions of the outer rectangle:

Length' = length - 2 * frame width = 5 - 2 * 1 = 3 units

Width' = width - 2 * frame width = 7 - 2 * 1 = 5 units

Now we can calculate the areas of the outer and inner rectangles:

Area of the outer rectangle = length * width = 5 * 7 = 35 square units

Area of the inner rectangle = length' * width' = 3 * 5 = 15 square units

Finally, to find the area of the shaded region, we subtract the area of the inner rectangle from the area of the outer rectangle:

Area of shaded region = Area of outer rectangle - Area of inner rectangle = 35 - 15 = 20 square units
