A and b are similar shapes the area of shap a is 200cm

The determinant of A is -74 and the determinant of B is -3. The determinant of A can be found using cofactor expansion.

The cofactor of entry (i,j) in a matrix A is the determinant of the matrix that results from deleting row i and column j from A. The determinant of A is then the sum of the products of the entries in row i and their corresponding cofactors.

In this case, the determinant of A is

det(A) = (3)(5) - (-1)(-1) = 16

The determinant of B can be found using the same method. The determinant of B is

det(B) = (-1)(4) - (1)(-2) = -2

The invertible matrix theorem states that a matrix A is invertible if and only if its determinant is non-zero. Therefore, both A and B are invertible matrices.

Here are 3 properties of each matrix:

A is a 4x4 matrix.

B is a 3x3 matrix.

The determinant of A is -74.

The determinant of B is -3.

Step-by-step explanation:

Using the central angle theorem, we can find the arm length of BD to be 118units.

Option C is correct.

The angle that an arc occupies at the centre of a circle is twice as large as the angle it occupies anywhere else around the circle's circumference, according to the central angle measure theorem.

Here in the question,

Length of the arc AC = 59.

As we can see that there is a quadrilateral inscribed inside the circle.

Arc AC = 1/2 arc BD

⇒ arc BD = 2 × arc length AC

⇒ arc BD = 2 × 59

⇒ arc BD = 118.

Therefore, the length of the arc BD = 118 units.

The required volume of Famotidine is 4 mL.

To calculate the required volume in milliliters (mL) for the provided dosage of Famotidine, we can use the following formula:

Volume (mL) = (Dosage ordered / Available dosage) * Volume per dose

We have:

Dosage ordered = 40 mg

Available dosage = 20 mg/2 mL (This means there are 20 mg of Famotidine in 2 mL)

Volume per dose = 2 mL

Let's substitute these values into the formula:

Volume (mL) = (40 mg / 20 mg) * 2 mL

Simplifying the expression:

Volume (mL) = 2 * 2 mL

Volume (mL) = 4 mL

The height of peak is around 2346.9 feet according to stated angles and distance.

The flat base, vertical height of the peak and angle of elevation form a right angled triangle. Hence, the trigonometric relation that will form is -

tan theta = perpendicular/base.

Let the distance between peak and hiker be x from the point of 500 feet

The height based on the first elevation angles of 30° -

tan 30° = perpendicular/(500 + x)

Perpendicular = 0.577 × (500 + x)

Performing multiplication

Perpendicular = 288.67 + 0.577x

The height based on the second elevation angles of 35° -

tan 35° = perpendicular/x

Perpendicular = 0.7 × x

Performing multiplication

Perpendicular = 0.7x

Now equating the height of peak -

288.67 + 0.577x = 0.7x

0.7x - 0.577x = 288.67

0.123x = 288.67

x = 288.67/0.123

x = 2346.9 feet

Hence, the height of peak is 2346.9 feet.

Answer:

$198

Step-by-step explanation:

To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!

The price of the watch before the discount is calculated to be £24.44.

As the total price of the watch and a pair of trainers is £53. 55 and the price of the trainer before the discount was £38, we first calculate the price of the trainers after the discount as follows;

discount on a pair of trainers = 15/100 × 38 =  £5.7

cost of trainers after discount =  £38 - 5.7 =  £32.3

Now the price of the watch after the discount can be calculated by subtraction as follows;

price of watch after discount = total price - price of trainers after discount

price of watch after discount =  £53. 55 - £32.3

price of watch after discount = £21.25

Now the price of the watch before the discount can be calculated as follows;

price of watch before discount = £21.25 × 15/100

price of watch before discount = £21.25 + £3.1875

price of watch before discount = £24.44

The radius of this cone, r = 5 cm

We need to find the volume of this cone. The formula for the volume of a cone is given by :

\(V=\dfrac{1}{3}\pi r^2 h\)

Put all the values,

\(V=\dfrac{1}{3}\times 3.14\times 5^2 \times 8\\\\=209.33\approx 209\ cm^3\)

What about least amount?

In mathematics, the term "least amount" is not commonly used. However, a similar term that is often used is "minimum".

The minimum value of a set of numbers or a function is the smallest value within that set or function. For example, if we have the set of numbers {2, 5, 7, 8, 10}, the minimum value is 2.

Similarly, in the context of optimization problems, we often seek to find the minimum value of a function to achieve the best possible outcome. This can involve finding the minimum value of a cost function in order to minimize the cost of a process, or finding the minimum value of a profit function to maximize the profit of a business.

Answer:

my answer is A

Step-by-step explanation:

if you work out the equation where you know that at the x intercept y=0 you will find A to be true

The slope field for the differential equation dy/dx = x² y² can be generated by plotting short line segments at each point (x, y) in the x-y plane. The direction of each line segment is determined by the value of x and y at that point, with steeper slopes indicating a larger rate of change.

To generate a slope field for the differential equation dy/dx = x² y², we need to plot short line segments at each point (x, y) in the x-y plane. The direction of each line segment is determined by the value of x and y at that point, with steeper slopes indicating a larger rate of change.

First, we can identify the stationary points of the differential equation by setting dy/dx = 0. This gives us the two lines y=0 and x=0, which intersect at the origin. We can see from the equation that any solution passing through the origin will have a slope of zero at that point, so the slope field will have horizontal lines for y=0 and vertical lines for x=0.

Next, we can look for other interesting features of the slope field. One such feature is the line y=1/x, which is a solution to the differential equation. To see this, we can substitute y=1/x into the equation and verify that both sides are equal. Along this line, the slope of the solution will be zero, since both x and y are changing at the same rate. Therefore, the slope field will have horizontal line segments along the curve y=1/x.

Overall, the slope field for dy/dx = x² y² will have horizontal lines for y=0, vertical lines for x=0, and horizontal line segments for y=1/x. In between these features, the slope of the line segments will increase as we move away from the origin, indicating that the rate of change of the solution is increasing.

The values of E(X) = 3.25 and Var(X) ≈ 2.238 for the number of spades in a hand of 13 cards chosen at random from a 52-card deck.

To find E(X) and Var(X) for the number of spades in a hand of 13 cards chosen at random from a 52-card deck, we will use the concepts of probability and statistics.

E(X), or the expected value, is the average number of spades you would expect to get in a hand of 13 cards. To find E(X), we can use the formula:

E(X) = (Number of spades in the deck / Total number of cards in the deck) * Number of cards drawn

E(X) = (13 spades / 52 cards) * 13 cards drawn
E(X) = (1/4) * 13
E(X) = 3.25

So, the expected number of spades in a 13-card hand is 3.25.

Next, let's find Var(X), or the variance, which is a measure of how much the number of spades can vary from the expected value. We can use the formula for variance of a hypergeometric distribution:

Var(X) = (Number of cards drawn * Number of spades * Number of non-spades) / ((Total number of cards in the deck)^2 * (Total number of cards in the deck - 1))

Var(X) = (13 cards drawn * 13 spades * 39 non-spades) / ((52 cards)^2 * (52 cards - 1))
Var(X) = (13 * 13 * 39) / (52 * 52 * 51)
Var(X) ≈ 2.238

So, the variance for the number of spades in a 13-card hand is approximately 2.238.

In summary, E(X) = 3.25 and Var(X) ≈ 2.238 for the number of spades in a hand of 13 cards chosen at random from a 52-card deck.
