Answer:  the area of the rectangle is 456 square millimeters.

Step-by-step explanation:

the perimeter is 88 mm, so if we let L be the length of the rectangle and W be the width, we can write the following equation to find the perimeter:

2L + 2W = 88 mm

Since the base of the rectangle is 38 mm, we know that the width of the rectangle is 38 mm, so we can substitute that value into the equation above to get:

2L + 2(38 mm) = 88 mm

Solving for L, we get:

2L = 88 mm - 2(38 mm)

2L = 88 mm - 76 mm

2L = 12 mm

Therefore, the length of the rectangle is 12 mm. Now that we know both the length and the width, we can find the area by multiplying the length and the width:

Area = L * W

Area = 12 mm * 38 mm

Area = 456 mm^2

Thus, the area of the rectangle is 456 square millimeters.

Answer:

A=228mm

Step-by-step explanation:

What formulas do we know?

Parameter= 2(length)+2(width)

Area= length x width

We can just substitute in values for parameters so,

88=2(length) + 2(38)

88=2L + 78 ------> 12=2L -------> L=6

Now we know width (which is just B) and Length (what we calculated)

Now we use area ----> Area= length x width

Area= (38)(6)-----> 228mm

The cost of polishing the floor of the square hall is ₹2343.75

The Side of Square Hall = 12.5 m

The cost of polishing the floor per meter sq. = ₹ 15

We have to find the cost of polishing the floor.

First we will calculate the area of floor of the square hall.

Area of a square is defined as the number of square units needed to fill a square. In general, the area is defined as the region occupied inside the boundary of a flat object or 2d figure. The measurement is done in square units, with the standard unit being square meters (\(m^{2}\)).

Area of square=\((12.5)^2\)

Area of square =\(12.5 \times 12.5\)

Area of square =156.25

The area of the floor of Square Hall is 156.25 \(\mathrm{~m}^2$\)

Per square meter cost of polishing the floor is ₹15,

To find the cost of polishing the floor of the square hall of area 156.25 sq. m, simply multiply 15 by the area of the floor of the square hall.

Therefore, the cost of polishing,

=15×156025

=2343.75

Therefore, the cost of polishing is ₹2343.75.

The equation 1 + 4 + 9 + ... + n² = n(n + 1)(2n + 1) / 6 is proven by mathematical induction.

We have,

To prove the equation 1 + 4 + 9 + ... + n² = n(n + 1)(2n + 1) / 6 using mathematical induction,

We will follow the three steps of mathematical induction:

The base case, the induction hypothesis, and the inductive step.

Step 1: Base case

Let's start by checking if the equation holds true for the base case, which is n = 1.

When n = 1, the left-hand side (LHS) is 1² = 1, and the right-hand side (RHS) is 1(1 + 1)(2(1) + 1) / 6 = 1.

Since LHS = RHS for the base case, the equation holds true.

Step 2: Induction hypothesis

Assume the equation holds true for some positive integer k, where k ≥ 1. This is our induction hypothesis:

1 + 4 + 9 + ... + k² = k(k + 1)(2k + 1) / 6

Step 3: Inductive step

We need to prove that if the equation holds true for k, it also holds true for k + 1.

Starting with the left-hand side of the equation, we add (k + 1)² to both sides:

1 + 4 + 9 + ... + k² + (k + 1)² = k(k + 1)(2k + 1) / 6 + (k + 1)²

Simplifying the right-hand side:

= [k(k + 1)(2k + 1) + 6(k + 1)²] / 6

= [(2k³ + 3k² + k) + (6k² + 12k + 6)] / 6

= (2k³ + 9k² + 13k + 6) / 6

= [(k + 1)(k + 2)(2k + 3)] / 6

We can see that the right-hand side is now in the form

(k + 1)((k + 1) + 1)(2(k + 1) + 1) / 6, which matches the equation for k + 1.

Since the equation holds true for k implies it holds true for k + 1, and the base case is true, we have proven the equation using mathematical induction.

Therefore,

The equation 1 + 4 + 9 + ... + n² = n(n + 1)(2n + 1) / 6 is proven by mathematical induction.

Systematic random sampling is sometimes used in place of simple random sampling due to its efficiency, representativeness, ease of implementation, and cost-effectiveness.

Systematic random sampling is sometimes used in place of simple random sampling for several reasons, including:
Efficiency:

Systematic random sampling can be more efficient than simple random sampling, as it involves selecting elements at regular intervals from the population.

This often reduces the time and effort needed to collect data compared to simple random sampling.
Representativeness:

Systematic random sampling may provide a more representative sample of the population.

By selecting elements at regular intervals, it ensures that different segments of the population are included, reducing the potential for sampling bias.
Ease of implementation:

Systematic random sampling is relatively easy to implement, as it involves fewer random selections compared to simple random sampling.

This makes it more practical for large populations or when a sampling frame is not readily available.
Cost-effectiveness:

Systematic random sampling can be more cost-effective than simple random sampling.

Since the process is more efficient, it may require fewer resources, such as time and personnel, to collect data.

A change in the price of chicken, the good's own price, will cause a movement along the demand curve for chicken, a normal good, resulting in an increase in the quantity demanded.

The demand curve for chicken represents the relationship between the price of chicken and the quantity of chicken demanded by consumers. The law of demand states that there is an inverse relationship between the price of a good and the quantity demanded, holding all other factors constant. In other words, as the price of chicken decreases, the quantity demanded of chicken increases, and vice versa.

A movement along the demand curve for chicken occurs when there is a change in the price of chicken. When the price of chicken decreases, ceteris paribus, consumers are willing to purchase more chicken at the lower price, resulting in an increase in the quantity demanded along the demand curve. Conversely, when the price of chicken increases, consumers are willing to purchase less chicken at the higher price, resulting in a decrease in the quantity demanded along the demand curve.

Other factors that can shift the demand curve for chicken include changes in consumer income, the prices of substitute or complementary goods, and changes in consumer preferences. However, these factors cause a shift in the entire demand curve, rather than a movement along the curve.

You will need 2 gallons of paint to paint the walls of the 20 ft by 20 ft room..

To determine the number of gallons of paint needed for the room, we need to calculate the total surface area of the walls.

First, calculate the area of one wall:
Area of one wall = height * length
Area of one wall = 10 ft * 20 ft
Area of one wall = 200 square feet

Since there are four walls in the room, we need to calculate the total area of all the walls:
Total area of walls = area of one wall * number of walls
Total area of walls = 200 square feet * 4 walls
Total area of walls = 800 square feet

Next, divide the total area of the walls by the coverage of one gallon of paint:
Gallons of paint needed = Total area of walls / Coverage of one gallon of paint
Gallons of paint needed = 800 square feet / 400 square feet per gallon
Gallons of paint needed = 2 gallons

Therefore, you will need 2 gallons of paint to paint the walls of the 20 ft by 20 ft room.

To paint the walls of a 20 ft by 20 ft room with 10 ft high walls, you will need 2 gallons of paint.

To calculate the amount of paint needed to cover the walls of a 20 ft by 20 ft room, we first need to determine the total area of the walls.

The room has four walls, each with a height of 10 ft. Since the walls go all the way around the room, the total perimeter of the room is (20 ft + 20 ft + 20 ft + 20 ft) = 80 ft.

To find the total area of the walls, we multiply the perimeter by the height: (80 ft) * (10 ft) = 800 square feet.

Since a gallon of paint covers 400 square feet, we divide the total area of the walls by the coverage per gallon: 800 square feet ÷ 400 square feet/gallon = 2 gallons.

Therefore, you will need 2 gallons of paint to cover the walls of the 20 ft by 20 ft room.

The function q(x) describes a parabolic shape that opens upwards and has its vertex at (4, -3).

The function q(x) is a quadratic function that has been translated down 3 units and right 4 units from the parent function f(x) = x^2. Specifically, q(x) is in vertex form, which makes it easy to identify the vertex of the parabola: (4, -3). The "1/2" coefficient in front of the squared term tells us that the parabola is "flatter" than the parent function, and it opens upwards because the coefficient is positive.

To graph q(x), we can start by plotting the vertex at (4, -3). Then we can find two additional points on either side of the vertex by plugging in x-values that are equidistant from the vertex. For example, if we plug in x=2, we get q(2) = 1/2 (2 - 4)^2 - 3 = -4. Similarly, if we plug in x=6, we get q(6) = 1/2 (6 - 4)^2 - 3 = -4. This tells us that the points (2, -4) and (6, -4) lie on the graph of q(x).

We can also determine the axis of symmetry of the parabola, which is the vertical line that passes through the vertex. In this case, the axis of symmetry is x = 4. This means that the parabola is symmetric about this line.

Overall, the function q(x) describes a parabolic shape that opens upwards and has its vertex at (4, -3). It is a useful tool for modeling various phenomena that exhibit this type of behavior, such as the trajectory of a ball thrown into the air or the shape of a satellite dish.
