The coordinates for the dilated figure would be A'(-2, 2), B'(-2, -1), C'(2, -1), and D'(2, 2).

The kind of dilation that was done is called a reduction.

When you dilate a figure with a scale factor k = 1/3, you are performing a reduction, because the scale factor is between 0 and 1. In this case, the dilation will shrink the original figure by a factor of 1/3.

To find the coordinates of the dilated points, multiply the x and y coordinates of each point by the scale factor (1/3):

A' = (-6 x 1/3, 6 x 1/3) = (-2, 2)

B' = (-6 x 1/3, -3 x 1/3) = (-2, -1)

C' = (6 x 1/3, -3 x 1/3) = (2, -1)

D' = (6 x 1/3, 6 x 1/3) = (2, 2)

The coordinates of the dilated figure are A'(-2, 2), B'(-2, -1), C'(2, -1), and D'(2, 2). This type of dilation is a reduction, as the figure becomes smaller.

The probability of drawing two hearts without replacement is 0.0588. The probability of drawing an ace followed by a king without replacement is 0.006.

Probability is a way to gauge how likely or unlikely something is to happen. Usually, it is stated as a number between 0 and 1, where 0 denotes that an event is impossible and 1 denotes that it is certain to happen.

6) To find the probability of drawing two hearts without replacement, we can use the formula:

P(two hearts) = (number of ways to choose 2 hearts) / (number of ways to choose 2 cards from a deck)

As there are 13 hearts in a standard deck of 52 cards, the number of ways to choose 2 hearts is given by the combination:

13 choose 2 = 13! / (2! * (13-2)!) = 78

The number of ways to choose 2 cards from a deck of 52 cards is:

52 choose 2 = 52! / (2! * (52-2)!) = 1326

Therefore, the probability of drawing two hearts without replacement is:

P(two hearts) = 78 / 1326 ≈ 0.0588 (rounded to four decimal places)

7) To find the probability of drawing an ace followed by a king without replacement, we can use the formula:

P(ace, then king) = P(ace) * P(king|ace not drawn)

The probability of drawing an ace is given by:

P(ace) = 4/52 = 1/13

After drawing an ace from the deck, there are 51 cards remaining, of which 4 are kings. Therefore, the probability of drawing a king given that an ace has not been drawn is:

P(king|ace not drawn) = 4/51

Hence, the probability of drawing an ace followed by a king without replacement is:

P(ace, then king) = (1/13) * (4/51) ≈ 0.006 (rounded to three decimal places).

Answer:

  181.875 cm³

Step-by-step explanation:

You want to know the amount of additional material Jessica needs to make a prism with a volume of 35 cm³ and one that is dilated by a factor of 2.5, given that she has 400 cm³ of material.

The dilation factor for volume is the cube of the linear dilation factor:

  2.5³ = 15.625

so the volume of the scaled-up prism will be ...

  (35 cm³) × 15.625 = 546.875 cm³

The total volume of material Jessica needs for the two prisms is ...

  35 cm³ + 546.875 cm³ = 581.875 cm³

Since Jessica has 400 cm³ of material, the amount she needs is ...

  581.875 cm³ - 400 cm³ = 181.875 cm³

Jessica needs 181.875 cm³ more material to make the second prism.

The general solution to the differential equation is y = -1/(3x³ + C)

Where C is an arbitrary constant.

The concept used to solve this differential equation is the separation of variables. Separated the variables on either side of the equation and then integrated both sides to get the general solution with a constant of integration.

Note that, the solution is valid only for y ≠ 0 as the differential equation is undefined for y = 0.

Here we have  

dy/dx = 9x²y²

Solve the differential equation using the separation of variables.

=> dy/dx = 9x² y²

Let's separate the variables by dividing both sides by y² and dx:

=> 1/(y²) dy = 9x² dx

Now we can integrate both sides:

=> ∫1/(y²) dy = ∫9x² dx

Using the power rule of integration, we get:

=> -1/y = 3x³ + C

Where C is the constant of integration.

To solve for y, we can multiply both sides by -1:

=> y = -1/(3x³ + C)

Therefore,

The general solution to the differential equation is y = -1/(3x³ + C)

The dimensions of the rectangle are either 25" by 8" or 20" by 10".

The perimeter of a two-dimensional shape is the space surrounding it. It is calculated using length units like inches or metres. The lengths of all the sides of a rectangle are added up to determine its perimeter.

Area is a unit used to describe how much room there is inside a two-dimensional form. It is calculated using area units like square inches or square metres. A rectangle's area is calculated by multiplying its length by its width.

The perimeter of the rectangle is given as:

Perimeter = 2(length + width)

Substituting the value we have:

90 = 2(L + W)

45 = L + W

Now, the area is given as:

Area = length × width

Substituting the values we have:

200 = L × W

The above equation can be written as:

W = 200/L

Substituting the value of W in the first equation we have:

45 = L + 200/L

45L = L² + 200

L² - 45L + 200 = 0

L = (45 ± √(45² - 4×1×200)) / (2×1)

L = (45 ± 5) / 2

L = 25 or L = 20

Now, for L = 25 the value of W is:

W = 200 / 25 = 8

For L = 20:

W = 200 / 20 = 10

Hence, the dimensions of the rectangle are either 25" by 8" or 20" by 10".

Answer:

The solutions to the equation x^2 = 4x + 41 are x = 2 + 2sqrt(11) and x = 2 - 2sqrt(11).

Step-by-step explanation:

To solve the equation x^2 = 4x + 41, we can first rearrange it as x^2 - 4x - 41 = 0.

Next, we can use the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation. In this case, a = 1, b = -4, and c = -41.

Substituting these values into the formula, we get:

x = (4 ± sqrt((-4)^2 - 4(1)(-41))) / 2(1)

Simplifying:

x = (4 ± sqrt(176)) / 2

x = (4 ± 4sqrt(11)) / 2

x = 2 ± 2sqrt(11)

Therefore, the solutions to the equation x^2 = 4x + 41 are x = 2 + 2sqrt(11) and x = 2 - 2sqrt(11).

The solution for the value of x is 55.

The measure of side ‘b’ in the given triangle ABC, with angle A measuring 54 degrees and angle C measuring 59 degrees and side BC measuring 11 is option-c:12.516, which is found using Sine-law.

In a scalene or oblique triangle (a non-right triangle), the law of sine describes the relationship between the sides and angles. Trigonometric laws such as the law of sines and law of cosines are crucial when "solving a triangle" by calculating the unknown angles or sides. The ratio of a triangle's side lengths to the sine of each of its opposite angles must be equal in order for the sine rule to apply. Triangle side length ratios to their corresponding opposite angles are connected by the law of sines. All three sides and the diagonal angles maintain the same ratio.

Given that ∠A= 54° ,∠C= 59° & side BC=a=11

We know that ∠A + ∠B + ∠C = 180°   {angle sum property}

Consider △ABC,

54° + 59° +  ∠B = 180°

113° +  ∠B = 180°

∠B = 180°- 113°

∠B = 67°

Applying Sine-Law,

[tex]\frac{A}{sin\ A} =\frac{B}{sin\ B} = \frac{C}{sin\ C}[/tex]

By using,

[tex]\frac{A}{sin\ A} =\frac{B}{sin\ B}[/tex] , we get:
