Find the first derivative of y=e^4x sin 4x

Given two similar triangles

The corresponding sides are proportions

So,

[tex]\dfrac{x}{y} =\dfrac{20}{90} =\dfrac{2}{9}[/tex]

So, the relation between x and y will be:

[tex]x=\dfrac{2}{9} y[/tex]

The area of the smaller triangle = 45 cm²

So, area =

[tex]\dfrac{1}{2} x\times y=45[/tex]

Substitute with x into the equation of the area to find the value of y

         [tex]\dfrac{1}{2} \times\dfrac{2}{9} y\times y=45[/tex]

[tex]y^2=\dfrac{45\times1\times9}{2} =\dfrac{405}{2}=202.5[/tex]

                [tex]y=\sqrt{202.5}[/tex]

Substitute with y into x

[tex]x=\dfrac{2}{9} \times\sqrt{202.5} =\frac{2\sqrt{202.5} }{9}[/tex]

So, the answer will be:

[tex]x=\frac{2\sqrt{202.5} }{9}[/tex]

The two streets that are the legs of the Triangle are Streets A and B.

The length of C street can be found to be 3. 61 miles.

If Dan can bike 4 miles in half an hour, then he can make the trip to Sarah's house in 30 minutes.

The length of C street can be found using the Pythagorean Theorem which is:

Length C ² = Leg A ² + Leg B²

This means the length of C street is:

Length C ² = 2 ² + 3 ²

Length C ² = 13

Length C = √ 13

= 3. 61 miles

This means that Dan can get to Sarah's house in 30 minutes if he is going at 4 miles per half hour.

The correct equation would be:

0b. A = 240 - 4h

Explanation:

If Clayton can plow 4 acres per hour, the number of acres he can plow in 'h' hours would be 4h.

Therefore, the number of acres left to plow would be the total number of acres (240) minus the number of acres he has already plowed (4h).

Hence, the equation that represents the number of acres left to plow would be A = 240 - 4h.

Answer: C.5

Step-by-step explanation:

The value of b, given the graph, the vertical and horizontal asymptote, would be - 8 .

At the y-intercept, x = 0. We can plug this into the equation and solve for y:

-4 = (a(0) + b) / (0 + c)

-4 = b / c

The vertical asymptote occurs when the denominator is equal to 0:

x + c = 0

x = -2

Thus, c = 2.

The horizontal asymptote occurs when the limit of the function as x approaches infinity is equal to a constant value:

y = a/c

3 = a/2

a = 3 * 2

= 6

The value of b would therefore be:

-4 = b / 2

The total cost is the same for both locations when there are 10 guests.

To determine the number of guests for which the total cost is the same at each location, we need to set up an equation and solve for the number of guests (let's call it x).

Roller rink cost: 5x + 55

Laser tag cost: 8x + 25

Now, set the two costs equal to each other and solve for x:

5x + 55 = 8x + 25

Subtract 5x from both sides:

55 = 3x + 25

Subtract 25 from both sides:

30 = 3x

Divide by 3:

x = 10

Answer: Q.a Arun thinks that -29/36 is exactly halfway between -8/9 and -13/18. We can check if this is true by finding the midpoint between -8/9 and -13/18 and seeing if it equals -29/36.

To find the midpoint between two numbers, we take the average of the two numbers. So the midpoint between -8/9 and -13/18 is:

((-8/9) + (-13/18))/2 = (-16/18 + (-13/18))/2 = -29/36

Since -29/36 is the same as the midpoint, Arun is correct.

Q.b To find the fraction exactly halfway between -1 3/4 and -11/6, we can start by converting the mixed number to an improper fraction:

-1 3/4 = -7/4

-11/6

To find the midpoint between -7/4 and -11/6, we take the average:

((-7/4) + (-11/6))/2 = (-21/12 + (-22/12))/2 = -43/24

Therefore, -43/24 is the fraction exactly halfway between -1 3/4 and -11/6 on the number line.

Answer: 185.64 inches

The surface area of the box is 185.64 square inches.

The area is the amount of area occupied by an object's flat (2-D) surface or shape.

To find the surface area of the box, we need to calculate the area of each face and then add them up.

The four faces are rectangles with dimensions 8.8 inches by 4.3 inches, so their area is 4(8.8)(4.3) = 151.36 square inches.

The other area can be described as 2(4.3)(4.3) =36.98 square inches.

Finally, we need to account for the rectangular tear on one of the sides, which has dimensions of 0.5 inches by 5.4 inches. This tear creates an additional face with area (0.5)(5.4) = 2.7 square inches.

Therefore, the total surface area of the tissue box is:

151.36 + 36.98 - 2.7 =  185.64 square inches.

Hence, the surface area of the box is 185.64 square inches.

Jamie will therefore need five days to complete the book as a result, P – 90 pages equals 3/8 of the book.

A mathematical strategy for resolving proportionality issues is the unitary method. Finding the price of one unit is the first step, and utilizing that value to determine the value of yet another quantity with a different quantity is the second. Consider being told, for instance, that an automobile drives 300 kilometres in 5 hours. You are able to employ the unitary technique as shown below to determine how far the car drives in eight hours. For example, 1 hour is equal to 300/5, or 60 miles. To calculate the value of eight hours, use this value: Since 8 hours are equal to 8/1 units, 480 miles are covered in 8 hours.

given

Let P represent the book's total number of pages.

Jessica reads 30 pages per day, which translates to 330 pages after 3 days, or 90 pages total.

5/8 of the book is still to be read, which indicates that 3/8 of it has already been. As a result, P – 90 pages equals 3/8 of the book.

Divide both sides by 5, and you get:

P = 144

To rewrite the quadratic function y = -9(x-1)²-6 in standard form, we need to expand the squared term and simplify the expression. Here are the steps:

Distribute the negative sign to the squared term: y = -9(x² - 2x + 1) - 6

Multiply -9 by each term inside the parentheses: y = -9x² + 18x - 9 - 6

Combine the constants: y = -9x² + 18x - 15

Step-by-step explanation:

The linear separable SVM is not always applicable in case of noise in the training data. When dealing with noisy training data, the performance of a linear separable SVM can be negatively affected, as it tries to find a perfect separation between the classes, which may not be possible in noisy data.

To deal with noisy training data, SVM can be modified by introducing a "soft margin" approach, which allows some flexibility in class separation. This is achieved by using a parameter called C (cost parameter), which controls the trade-off between achieving a wider margin and minimizing classification errors. A higher value of C results in a smaller margin but fewer classification errors, making the model more sensitive to noise. A lower value of C results in a larger margin, allowing more classification errors but providing better generalization to handle noise.

Choosing the appropriate value for C is crucial for the SVM model's performance. Additionally, nonlinear kernel functions, such as the radial basis function (RBF) kernel, can be used instead of a linear kernel to map the data into a higher-dimensional space. This allows the SVM to find more complex decision boundaries, which can better handle noisy data.

In summary, to deal with noisy training data in SVM, one can use the soft margin approach by adjusting the cost parameter (C) and opt for nonlinear kernel functions like RBF, enabling the model to generalize better and handle noise effectively.

Based on the given information, the angle is C. 22.1° an  A. 20.4°.

Trigonometric functions are mathematical functions that relate the angles and sides of a right triangle.

The basic trigonometric functions are:

Sine (sin): the ratio of the length of the side opposite an angle to the length of the hypotenuse of the triangle.

Cosine (cos): the ratio of the length of the side adjacent to an angle to the length of the hypotenuse of the triangle.

Tangent (tan): the ratio of the length of the side opposite an angle to the length of the side adjacent to the angle.

We can use the trigonometric function tangent to find angle R in the right triangle:

tan(R) = opposite/adjacent = PQ/QR

tan(R) = 5.2/13.4

R = tan⁻¹(5.2/13.4)

R ≈ 22.1°

Therefore, the answer is C. 22.1° rounded to one decimal place.

Using the Pythagorean theorem, we can find the length of side AB:

AB = √(AC² - BC²)

= √(25² - 10²)

= √(575)

Now we can use the sine function to find the measure of angle C:

sin(C) = BC/AB

C = sin⁻¹(BC/AB)

= sin⁻¹(10/√(575))

≈ 20.4°
