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.

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:

x = 6 - y = 6 - 4 = 2

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

The area of the Shaded region, when the frame is 1 unit wide, is 20 square units.

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

Therefore, the area of the shaded region, when the frame is 1 unit wide, is 20 square units.

Given statement solution is :- It  would cost $680 to install tile in the dining room and $315 to install carpet in the bedroom.

To find the cost of installing tile in the dining room and carpet in the bedroom, we need to calculate the areas of both rooms first.

Given:

Every 2 centimeters on the floor plan represents 1 meter of the house.

Dining Room:

On the floor plan, the dining room is 8 cm by 10 cm.

Converting this to meters, the dimensions of the dining room are 8 cm / 2 = 4 meters by 10 cm / 2 = 5 meters.

The area of the dining room is 4 meters * 5 meters = 20 square meters.

Bedroom:

On the floor plan, the bedroom is 6 cm by 10 cm.

Converting this to meters, the dimensions of the bedroom are 6 cm / 2 = 3 meters by 10 cm / 2 = 5 meters.

The area of the bedroom is 3 meters * 5 meters = 15 square meters.

Now, let's calculate the costs.

Cost of Tile:

The cost of installing tile is $34 per square meter.

The area of the dining room is 20 square meters.

Therefore, the cost of installing tile in the dining room is 20 square meters * $34/square meter = $680.

Cost of Carpet:

The cost of installing carpet is $21 per square meter.

The area of the bedroom is 15 square meters.

Therefore, the cost of installing carpet in the bedroom is 15 square meters * $21/square meter = $315.

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

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

Answer:

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.

From the given options, the pair of shoes that costs $20 and is sold to the customer for $35 and the shirt that costs $12 and is sold to the customer for $20 both show a percent increase greater than 50%.

To determine which options show a percent increase greater than 50%, we need to calculate the percent increase for each option.

1)A jacket that costs $18 is sold to the customer for $25.

Percent increase = [(New Value - Old Value) / Old Value] * 100

= [(25 - 18) / 18] * 100

≈ 38.89%

2)A hat that costs $8 is sold to the customer for $12.

Percent increase = [(New Value - Old Value) / Old Value] * 100

= [(12 - 8) / 8] * 100

= 50%

3)A pair of shoes that costs $20 is sold to the customer for $35.

Percent increase = [(New Value - Old Value) / Old Value] * 100

= [(35 - 20) / 20] * 100

= 75%

4)A shirt that costs $12 is sold to the customer for $20.

this is a simple diameter....work on it by breaking it down

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.

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.
