At the end of 24 hours, 48 cupcakes will have grown. Every 8 hours, two cupcakes are grown, so after 24 hours, 24 sets of two cupcakes have been grown. Therefore, 48 cupcakes have grown.

At the end of 24 hours, 48 cupcakes will have grown. This is because every 8 hours, two cupcakes are grown. After 24 hours, 24 sets of two cupcakes have been grown. This means that in the 24 hours, two cupcakes were grown a total of 24 times. When this total is multiplied by two, it results in 48 cupcakes being grown. Therefore, after 24 hours, 48 cupcakes have grown. It is important to note that this is only the number of cupcakes that have grown in the 24 hour period, and not the total number of cupcakes. This number includes any cupcakes that were already present at the beginning of the 24 hour period, so the total number of cupcakes at the end of the 24 hour period could be higher than 48.

1. Calculate the number of sets of cupcakes grown in 24 hours: 24 hours divided by 8 hours = 3 sets

2. Calculate the number of cupcakes grown in 24 hours: 3 sets multiplied by 2 cupcakes = 6 cupcakes

3. Calculate the total number of cupcakes grown in 24 hours: 6 cupcakes multiplied by 4 sets = 24 cupcakes

Answer:

f(-4) = -18

Step-by-step explanation:

So we have f(x) and we have f(-4). The X is where the -4 is so that means x = -4.

Since we know that, we plug it into the equation. Everywhere we see an X

So instead of 5(x) + 2, it will be 5(-4)+2.

5 times -4 is -20, which makes it -20 + 2

-20 + 2 = -18. Giving us our answer

Based on the total area of the floor, the cost to cover the floor is $1569.75.

The area of the floor is calculated as follows:

Area of floor = Area of the trapezium + Area of rectangle

Area of the trapezium = (a + b)/ * h

a = 30 - 20 ft or 10 ft

b = 35 ft

h = 15 ft

Area of the trapezium = (10 + 35)/2 * 15

Area of the trapezium = 337.5 ft²

Area of rectangle = 40 * 20

Area of rectangle = 800 ft²

Area of floor = 800 ft² + 337.5 ft² or 1137.5 ft²

The cost to cover the floor = 1137.5 * $1.38

As per unitary method,

a) The length of the rope left after tying the parcel 260 cm

b) The initial length of the rope was 305cm.

The unitary method is a mathematical tool used to solve problems involving the partition of a whole into parts.

(a) To find the length of the rope left after tying the parcel, we subtract the length of the rope used to tie the parcel from the initial length of the rope. The length of the rope left is:

=> Initial length of the rope - Length of rope used to tie the parcel = Length of rope left

We are told that Ravi used 45cm of the rope to tie a parcel. Therefore, the length of rope left can be expressed as:

Initial length of the rope - 45 = Length of rope left

(b) To find the initial length of the rope, we add the length of the rope used to tie the parcel to the length of the rope left.

We know that the length of the rope left is divided into 4 pieces of 65cm each. Therefore, the total length of the rope left is

=> 4 x 65 = 260cm.

We can now use this information to find the initial length of the rope:

Length of rope left + Length of rope used to tie the parcel = Initial length of the rope

260 + 45 = 305cm

The period of the function is 1.57 s.

The amplitude of the function is 6.

The equation of the midline, y = 6 sin 4x + 0.

The general form of a sinusoidal function is y = A sin(Bx - C) + D,

where:

For the given function y = 6 sin 4x, we can see that:

A = 6 (the amplitude is the absolute value of the coefficient of the sine function)

B = 4 (the coefficient of x inside the sine function determines the period)

C = 0 (there is no horizontal shift)

D = 0 (there is no vertical shift, so the midline is the x-axis)

Therefore, the period T is given by:

T = 2π/B = 2π/4 = π/2 = 1.57 s

The midline is the x-axis, so its equation is y = 0.

The amplitude is A = 6.

Therefore, we can write the equation of the function in the general form as:

y = 6 sin 4x + 0

or

y = 6 sin(4x)

Note that since the midline is the x-axis and there is no vertical shift, the sine function will oscillate between -6 and 6.

The angles m∠w and m∠y are supplementary angles and their measures are 50° and 130° respectively.

If two angles add up to 180°, they are considered supplementary angles, we can observe that the positions of the angles formed by the transversal cutting the parallel lines makes the two angles on a straight line which are supplementary so;

4x + 6 + 12x - 2 = 180

16x + 4 = 180°

16x = 180 - 4 {subtract 4 from both sides}

16x = 176

x = 176/16 {divide through by 16}

x = 11.

m∠w = 4(11) + 6 = 50°

m∠y = 12(11) - 2 = 130°

Answer: The area of right triangle ABC can be found using the formula (1/2)bh, where b is the length of the base and h is the height. Since the base of the triangle is 5 units and the area is 12.5 square units, the height must be 2.5 units.

Knowing that point C is on the line x = -2, we can use the height of 2.5 units to find the y-coordinate of point C.

Starting from the line y = 2, moving 2.5 units down will give us a y-coordinate of y = 2 - 2.5 = -0.5.

So, a possible y-coordinate of point C is -0.5.

Step-by-step explanation:

A = 1/2 (b)(h)

12.5 = 1/2 (5)(h)

Multiply both sides by 1/2 or 2 to cancel out the fraction

2 x 12.5 = 1/2 (5)(h) x 2

25 = 5h

Divide both sides by 5 to get h on its own

25/5 = 5h/5

h = 5

Divergence and curl are two important concepts in vector calculus. They are used to describe the behaviour of vector fields, which are functions that assign a vector to each point in space.

Divergence is a scalar function that describes the extent to which a vector field is spreading or contracting at a given point. If the vector field is spreading, the divergence at that point is positive; if it is contracting, the divergence is negative.

If the vector field is unchanged in size, the divergence is zero. The formula for the divergence of a vector field is given by the dot product of the gradient of the field with the unit normal vector at a point.

Curl, on the other hand, is a vector function that describes the rotational aspect of a vector field. It is defined as the cross-product of the del operator and the field. Curl measures the rate at which the vectors in a field are rotating about a point. If the curl is zero, the field is said to be irrotational. If the curl is non-zero, the field is said to be rotational.

Divergence and curl cannot be defined for a scalar function because a scalar function assigns a single scalar value to each point in space, while divergence and curl describe the behaviour of vector fields.

A scalar function has no direction or rotational component, so there is no way to describe the spreading or contracting behaviour or the rotational behaviour of the function.

Answer:

Step-by-step explanation:

There are 6 possible outcomes for each of the two rolls, so there are 6 x 6 = 36 possible outcomes for the sum of two rolls.

Event A: The sum is greater than 8.

There are five possible ways to achieve a sum greater than 8: (3, 6), (4, 5), (4, 6), (5, 4), and (6, 3). Each of these outcomes has a probability of 1/36. Therefore, the probability of event A is:

P(A) = 5/36

Event B: The sum is an even number.

There are three possible ways to achieve an even sum: (1, 1), (2, 2), and (3, 3). Each of these outcomes has a probability of 1/36. There are also three possible ways to achieve a sum of 4: (1, 3), (2, 2), and (3, 1). Each of these outcomes has a probability of 1/36. Similarly, there are three possible ways to achieve a sum of 6, 8, 10, and 12. Therefore, the probability of event B is:

P(B) = (3 + 3 + 3 + 3 + 3 + 3)/36

P(B) = 18/36

P(B) = 1/2

Therefore, the probability of event A is 5/36 and the probability of event B is 1/2.
