Power is the rate at which work is done or energy is transferred. In this case, the girl used a force of 98 N to lift the painting to a height of 0.5 m in 0.75 seconds, resulting in 49 J of work done. The power used was calculated to be approximately 65.33 watts.

To calculate the power used by the girl while lifting the painting, we need to use the formula: Power (P) = Work (W) / time (t).

Firstly, we need to calculate the work done by the girl in lifting the painting. Work is defined as the product of force and distance. As there is no information about the force applied, we will assume that the girl lifted the painting with a constant force. Therefore, the work done can be calculated as:

Work (W) = force x distance

Here, the distance is 0.5 m, and we can use the formula for weight to calculate the force required to lift the painting. As we know that the mass of the painting is not given, we can assume it to be 10 kg (a medium-sized painting).

Weight (Wt) = mass x acceleration due to gravity
Wt = 10 kg x 9.8 m/s² = 98 N

Therefore, the work done by the girl is:

W = 98 N x 0.5 m = 49 J

Now, we can use the formula for power to calculate the power used by the girl.

P = W / t
P = 49 J / 0.75 s
P = 65.33 W (approx.)

Therefore, the girl used approximately 65.33 watts of power while lifting the painting.

The girl used 65.3 watts of power to lift the painting.

To calculate power, we need to know the work done and the time taken.

We can use the formula:

power = work/time

The work done is equal to the force applied multiplied by the distance moved. Since we don't know the force, we can use the formula for work in terms of mass, gravity, and height:

work = mgh

where m is the mass, g is the acceleration due to gravity, and h is the height lifted.

Assuming the painting has a mass of 10 kg and the acceleration due to gravity is 9.8 m/s², the work done is:

work = (10 kg) x (9.8 m/s²) x (0.5 m) = 49 J

The time taken is 0.75 seconds.

So the power used is:

power = work/time = 49 J / 0.75 s = 65.3 watts

Therefore, the girl used 65.3 watts of power to lift the painting.

(e) The length of reflection of AB is same as length of line-segment AB.

When reflecting a line segment across the x-axis, the x-coordinates of all points remain the same, but the y-coordinates become their opposites.

So, for the line segment AB, the x-coordinate of point A remains 0, and the x-coordinate of point B remains 4. However, the y-coordinate of point A becomes -1, and the y-coordinate of point B becomes -6. This results in a new line segment A'(0, -1) and B'(4, -6).

The height of the cuboid, after calculations, in the form (a+ b√3)m, is (6√3 - 9)/47 meters.

Let the height of the cuboid be h meters. The area of the square base is given by:

(2 + √3)² = 4 + 4√3 + 3 = 7 + 4√3 m²

The total surface area of the cuboid is the sum of the areas of the six rectangular faces. Since the base is a square, the area of each of the four vertical rectangular faces is also (2 + √3) × h = (2h + h√3) m². Therefore, we have:

Total surface area = 4(7 + 4√3) + 2(2h + h√3)(2 + √3) = 8h + 26 + (22 + 16√3)h

Since we know that one of the sides has area (2√3 - 3) m², we can set up another equation:

(2h + h√3)(2 + √3) = 2√3 - 3

Expanding the left side and simplifying, we get:

(2h + h√3)(2 + √3) = 2√3 - 3

4h + 7h√3 = 2√3 - 3

h(4 + 7√3) = 2√3 - 3

h = (2√3 - 3)/(4 + 7√3)

We can rationalize the denominator by multiplying the numerator and denominator by the conjugate of the denominator:

h = [(2√3 - 3)/(4 + 7√3)] × [(4 - 7√3)/(4 - 7√3)]

h = (8√3 - 12 - 14√3 + 21)/(16 - 63)

h = (9 - 6√3)/(-47)

The function used to model the monthly profit for x trinkets produced are f(x) = -4(x - 50)(x - 250). The maximum profit occurs when 150 trinkets are produced.

The quadratic function that can be used to model the monthly profit for x trinkets produced is:

f(x) = -4(x - 50)(x - 250)

This is because the function is in the form of a quadratic equation, which is y = ax² + bx + c. In this case, a = -4, b = 1200, and c = 0. When we expand and simplify the equation, we get:

f(x) = -4x² + 1200x

This equation represents a parabola with a maximum value at x = 150. Therefore, the maximum profit occurs when 150 trinkets are produced.

To find the area of the semi-circle patio, we need to use the formula for the area of a circle, which is A = πr^2, where π is 3.14 and r is the radius of the circle.

However, since we only have a semi-circle, we need to divide the result by 2 to get the area of the half-circle.

In this case, the radius of the semi-circle is half of the diameter, which is given as 6.75 feet. So, the radius is 6.75/2 = 3.375 feet.

Now, we can plug this value into the formula:

Area is the measure of the size of a two-dimensional surface or region. It is typically measured in square units, such as square meters (m²) or square feet (ft²). The area of a shape can be calculated by multiplying the length and the width of the shape. Different shapes have different formulas for calculating their area, such as the formula for the area of a rectangle, which is length x width, or the formula for the area of a circle, which is πr², where r is the radius of the circle and π is a mathematical constant approximately equal to 3.14159.

Here,

Let's call the total area of the forest "T".

We know that 25 acres of the forest is covered by coniferous trees. Therefore, the remaining area of the forest is:

T - 25

We also know that the shrubs and bushes constitute 42% of the total area of the forest. This means that:

0.42 x T = area covered by shrubs and bushes

6x106 grams=6.0x106 grams=6.0x106−1×101 grams=6.0x105×101 grams=6.0x105+1 grams=6.0x107 grams

Similarly, for the silverback gorilla, we get:

2x105 grams=2.0x105 grams=2.0x105−1×101 grams=2.0x104×101 grams=2.0x104+1 grams=2.0x105 grams

Therefore, the values of b and c are b=7,c=5

To find the value of m, we need to divide the mass of the African elephant by the mass of the silverback gorilla and write the result in scientific notation. We get:

Mass of silverback gorillaMass of African elephant​=2.0x105 grams6.0x107 grams​=2.06.0​×105107​=3.0×107−5=3.0×102

Therefore, by unitary method the answer will be m=2.
