Step-by-step explanation:

Given that:

Total number of questions = 120

To fly directly to the field, the crew should fly in a direction of approximately 7.3 degrees south of east. The crew should fly approximately 230.45 miles directly to the field.

To solve this problem using components, we can break down the initial and final displacements into their x and y components.

In the initial leg, the plane flies 220 miles north of east. This can be represented as a displacement vector with an x-component of 220*cos(45°) = 155.56 miles (eastward) and a y-component of 220*sin(45°) = 155.56 miles (northward).

In the second leg, the plane changes direction to 54.0 degrees south of east and flies 124 miles. We can represent this displacement as a vector with an x-component of 124*cos(54°) ≈ 65.17 miles (eastward) and a y-component of -124*sin(54°) ≈ -97.53 miles (southward).

To find the resultant displacement vector, we can add the x-components and y-components separately. Adding the x-components, we get 155.56 miles + 65.17 miles = 220.73 miles (eastward). Adding the y-components, we get 155.56 miles - 97.53 miles = 58.03 miles (northward).

Therefore, the plane's resultant displacement from its initial position is approximately 220.73 miles eastward and 58.03 miles northward.

To determine the direction to fly directly to the field, we can use trigonometry. The angle can be calculated as arctan(y-component/x-component) = arctan(58.03/220.73) ≈ 7.3° south of east.

In terms of the distance the crew should fly directly to the field, we can use the Pythagorean theorem to calculate the magnitude of the resultant displacement. The magnitude is given by the square root of the sum of the squares of the x and y components: sqrt((220.73 miles)^2 + (58.03 miles)^2) ≈ 230.45 miles.

Therefore, the crew should fly approximately 230.45 miles directly to the field.

If a function is not continuous, it may or may not be differentiable.

The differentiability of a function is not determined solely by its continuity.

A continuous function is a function that can be drawn without picking up a pen. In mathematical terms, a function f(x) is continuous if, as x approaches a point a, f(x) approaches f(a).

For a function to be differentiable, it must be continuous. If a function is not continuous, it is not differentiable. However, the opposite is not always true; a function may be continuous but not differentiable.

In summary, a function that is not continuous may or may not be differentiable, while a function that is differentiable must be continuous.

The area of a pool from the given situation is 816 ft².

Given that, the dimensions of plot is 50 ft and 40 ft.

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Here, area of a plot = Length × Width

= 50 × 40

= 2000 ft²

Area of a pool = Area of a plot - Area of a grass

= 2000 - 1184

= 816 ft²

where (h, k) is the center in our case ( -5, -5) and r is the radius that in our case r=2, so substitute

(x+5)²+(y+5)²=2²

Answer:

\((x+5)^2+(y+5)^2=4\)

Step-by-step explanation:

Hi there!

Equation of a circle: \((x-h)^2+(y-k)^2=r^2\) where the circle is centered at (h,k) and r is the radius

1) Determine the center of the circle

On the graph, we can determine that the circle is centered at the point (-5,-5). Plug this into the equation:

\((x-(-5))^2+(y-(-5))^2=r^2\\(x+5)^2+(y+5)^2=r^2\)

2) Determine the value of r²

In the graph, we can see that the radius of the circle is equal to 2 units. Therefore, the value of r² is 4. Plug this back into the equation:

\((x+5)^2+(y+5)^2=4\)

The dishonest shopkeeper used a weighing machine that considers 900 grams as 1 kilogram. By selling 3 kilograms of sugar, they earned Rs. 12 more than they should have.

In this problem, the dishonest shopkeeper used a weighing machine that takes 900 grams as 1 kilogram. Therefore, if a customer bought 1 kilogram of sugar, the shopkeeper would only give them 900 grams of sugar. However, the cost per kilogram of sugar is Rs. 40.

To find out how much more money the shopkeeper earned by selling 3 kilograms of sugar to the customer, we need to first find out how much sugar the customer actually received for 3 kilograms. The customer would have actually received 2.7 kilograms of sugar because the shopkeeper's weighing machine takes 900 grams as 1 kilogram.

So, the total cost of 2.7 kilograms of sugar would be (2.7 x 40) Rs. 108. The shopkeeper would have earned Rs. 12 more by using this dishonest method to sell 3 kilograms of sugar. This is because the shopkeeper would have sold 3 kilograms of sugar at the rate of 40 Rs./kg whereas the customer only received 2.7 kilograms of sugar.

Therefore, the shopkeeper earned Rs. 12 more than they should have by using this method.

Answer:

(a) To solve a system of equations using elimination, we can eliminate one of the variables by adding or subtracting the equations. In this case, we can add the two equations to eliminate the variable y:

x - y = 11

2x + y = 19

----------

3x = 30

Dividing both sides of the equation by 3, we find that x = 10. We can then substitute this value into one of the original equations to find the value of y:

x - y = 11

10 - y = 11

-y = 1

y = -1

Therefore, the solution to the system of equations is x = 10 and y = -1. Answer: (10, -1).

________________________________________________________

(B)

To solve this system by elimination, we need to eliminate one of the variables by adding or subtracting the two given equations. Let's first multiply the first equation by 2 to obtain:

2 * (x - y = 11)

2x - 2y = 22

Next, we add this equation to the second given equation to eliminate the variable y:

2x - 2y + 2x + y = 22 + 19

3x - y = 41

We can now solve for x by dividing both sides of the equation by 3:

3x - y = 41

(3x - y) / 3 = 41 / 3

x = 14

We can now substitute this value for x in either of the original equations to solve for y. Let's use the second equation:

2x + y = 19

2 * 14 + y = 19

28 + y = 19

y = -9

Therefore, the solution to the system of equations is x = 14 and y = -9.
