y = 2 is the solution of  differential equation .

What exactly does differential equation mean?

An equation that connects one or more unknown functions and their derivatives is known as a differential equation in mathematics.

                               Applications typically use functions to describe physical quantities, derivatives to indicate the rates at which those quantities change, and differential equations to define a relationship between the two.

( x logx )dy/dx + y = 2xlogx

dividing by xlogx, we get

  dy/dx + y/xlogx  = 2

   d(IF × Y ) = 2logx dx

  IF  =  e∫1/xlogx dx

        = [tex]e^{log(logx)} = logx[/tex]

rightarrow Multiplying by IF, we get

      d(IF * Y ) = 2logx dx

   By integrating, we get

y logx = ∫2 logx dx

 By using Product Rule on RHS, we get

   ylogx = 2[logx ∫ 1 - ∫((∫1) d/dx(logx)) dx

  ylogx =  2[x(logx - 1 )] + c

If the function is f(x) = eˣ Cos(x) where (0≤ x ≤2π) , then the function will be increasing in interval (0, π/4) U (7π/4, 2π), and decreasing in interval (π/4, 7π/4) .

In order to find the intervals where function f(x) = eˣ Cos(x) is increasing and where it is decreasing, we find the points where the derivative of the function, f'(x), is positive and negative,

The derivative of function : f(x) = eˣ cos(x) is:

⇒ f'(x) = eˣ cos(x) + eˣ (-sin(x))

⇒ eˣ (cos(x) - sin(x))

So , To find the intervals where f'(x) is positive or negative, we can use the sign of the derivative to determine if the function is increasing or decreasing.

we  know that ;

⇒ When f'(x) > 0, the function is increasing.

⇒ When f'(x) < 0, the function is decreasing.

For function  " eˣ (cos(x) - sin(x)) " ,

we can see that f'(x) is positive when cos(x) > sin(x) and negative when cos(x) < sin(x).

By using a unit circle, we can see that the inequality cos(x) > sin(x) is satisfied for x in the interval (0, π/4) U (7π/4, 2π), and

The percent change of the data set is 10%.

Percentage change is a way to describe the difference between an old value and a new value, expressed as a ratio and then multiplied by 100.

If the price of a product was $5 last month and it increased to $5.50 this month, we can calculate the percentage change as

=> (5.50 - 5) / 5 x 100 = 10%.

This means that the price of the product has increased by 10% compared to last month. If the price had gone down, we would have a negative percentage change.

Percentage change is a useful tool to compare data sets, especially when dealing with large numbers.

30x2 is 60 so on the first box u put 2. Then u multiply again 30x2 which is 60 so u put the 60 on the box below the 76. U subtract

Next, you would subtract it which would turn out to be 16. Since 16 can't go in 30 equally, u would drop down the 2 in the 762 now you can do 30 into 162 which is 5 times bc 30x5 is 150 and doesn't go over so u put the 5 in the box next to the 2.

30x5 is 150, u put that in the box below 162. Then u subtract 162-150 which is 12. So you have a remainder of 12.

The area under the curve y = |x + 3| above the x-axis and between x = -6 and x = 0 is 9 units^2.

What is the area under the curve?

The area under a curve refers to the area between a curve and the -axis. This area could be entirely above the -axis, entirely below the -axis, or a combination of above and below the -axis. In calculus, the area under a curve is a visual representation of an integral.

The graph of y = |x + 3| is a piecewise linear function that starts at (3,0), increases linearly as x decreases to -3, reaches a maximum value of 3 at x = -3, and then decreases linearly as x decreases further to -6. The area under the curve y = |x + 3| above the x-axis and between x = -6 and x = 0 can be calculated by finding the area of two triangular regions. One triangular region is formed by the line y = x + 3 from x = -6 to x = -3 and the x-axis, and the other triangular region is formed by the line y = -(x + 3) from x = -3 to x = 0 and the x-axis. The area of each triangular region can be calculated using the formula 1/2 * base * height, and the total area is the sum of the areas of the two triangular regions.

Answer: False

Step-by-step explanation:

7 is not an even number, and it never will be.

Even though january has 31 days, 7 is an odd number.

False. 7 is an odd number. This is because an even number is a number which can be divided by 2 without a remainder. 7 cannot be divided by 2 without a remainder, so it is an odd number.

To calculate this, we can use the remainder operator. This operator is represented by the percentage sign (%). When using this operator, the result is the remainder of a division operation. For example, if we divide 7 by 2, the result is 3 with a remainder of 1. If we write this as an equation, it will be 7 % 2 = 1. This means that 7 is not evenly divisible by 2, and is thus an odd number.

The particle is speeding up over the time interval (10/6, ∞).

The particle is speeding up when its acceleration is positive, which occurs when its second derivative is greater than 0. The second derivative of x (t) is 6t - 10, so the particle is speeding up when t > 10/6. Therefore, the particle is speeding up over the time interval (10/6, ∞).

To calculate this, we take the second derivative of x (t):

x''(t) = 6t - 10

We then set this equal to 0 and solve for t

6t - 10 = 0

t = 10/6

2/3 = 0.666666666...

mrs. utley's class has a ratio of 5/7.

5/7 = 0.714285714...

so, the class of mrs. Utley had a greater ratio.

to compare the ratios (like any fraction) within calculating their decimal value, we need to bring them to the same denominator :

So, when R is rotated along the line y = 4, the volume of the solid formed is roughly 12.57 cubic units. So, when R is rotated about the line y = 5, the volume of the solid formed is roughly 81.34 cubic units.

Every three-dimensional item requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an item inside the confines of three-dimensional space. It is also known as the object's capacity.

Here,

The volume of the solid generated when R is rotated about the line y = 4 is given by the formula:

V = π * ∫[a,b] (x² - 4)² dx

where a and b are the x-coordinates of the points where the parabola y = x² intersects the line y = 4. To find these points, we set y = x² and y = 4 and solve for x:

x²= 4

x = ±2

So the points of intersection are (2, 4) and (-2, 4). The region R is the part of the parabola between these points, so a = -2 and b = 2.

Substituting these values into the formula for V, we have:

V = π * ∫[-2,2] (x² - 4)² dx

Evaluating the definite integral, we obtain:

V = π * [x⁵/5 - 4x³/3 + 16x] evaluated from -2 to 2

= π * (16/5 - 16/3 + 16 - (-16/5 + 16/3 - 16))

= π * (32/5)

= 12.57 ≈ 12.57 (rounded to 4 decimal places)

For the volume of the solid generated when R is rotated about the line y = 5, we can use the same formula:

V = π * ∫[a,b] (x² - 5)² dx

where a and b are the x-coordinates of the points where the parabola y = x² intersects the line y = 5. These can be found in the same way as before:

x² = 5

x = ±√5

So the points of intersection are (√5, 5) and (-√5, 5). The region R is the part of the parabola between these points, so a = -√5 and b = √5.

Substituting these values into the formula for V, we have:

V = π * ∫[-√5,√5] (x² - 5)² dx

Evaluating the definite integral, we obtain:

V = π * [x⁵/5 - 5x³/3 + 25x] evaluated from -√5 to √5

= π * (25/5 - 25/3 + 25√5/2 - (-25/5 + 25/3 - 25√5/2))

= π * (50/3 + 25√5)

= 50.97 + 25√5 ≈ 50.97 + 25 * 2.236 = 81.34 (rounded to 2 decimal places)

So the volume of the solid generated when R is rotated about the line y = 4 is approximately 12.57 cubic units. So the volume of the solid generated when R is rotated about the line y = 5 is approximately 81.34 cubic units.

The absolute maximum value of f is 1.

The function f(x) is defined as the natural logarithm of x (lnx) divided by x. This function is undefined when x is equal to 0, but for positive x values, the maximum value of f(x) is 1. To prove this, we need to take the derivative of f(x) and set it equal to 0. We can calculate the derivative of f(x) by using the quotient rule.

The quotient rule states that for two functions u(x) and v(x), the derivative of their quotient can be calculated by taking the derivative of u(x) times v(x) minus the derivative of v(x) times u(x), all divided by v(x)2. After taking the derivative of f(x) = lnx/x, we get f'(x) = (1/x) – (lnx/x2).

Now we set f'(x) = 0 and solve for x. This gives us x = 1, so when x = 1, we get the maximum value of f(x) = ln1/1 = 1. Therefore, the absolute maximum value of f is 1.

The values using Law of Sines are:

∠ B = 62∘; b = 11.58 and c = 16.40.

The relationship between a triangle's sides and angles is demonstrated using the sine rule. It is specified as:

A/Sin(A) = B/Sin(B) = C/Sin(C)

Where A, B, and C are indeed the angles and A, B, and C are the angles' opposing sides.

∠ A = 43 ∘ , ∠ C = 75 ∘ , b = 15 ;

Part a:

∠ B = 180 -  ∠ A  -  ∠ C

∠ B = 180 - 43 ∘  - 75∘

∠ B = 62∘

Part b: the value of a.

a/Sin(A) = b/Sin(B)

a =  b/Sin(B) * Sin(A)

a = 15/Sin(62) * Sin(43)

b = 11.58

Part c: the value of c

b/Sin(B) = c/Sin(C)

c = b/Sin(B) * Sin(C)

c = 15/Sin(62) * Sin(75)

c = 16.40

Thus, the values using Law of Sines are obtained.

In the exponential function y = 3 × q⁵ the starting value is 3.

The formula for an exponential function is f(x) = aˣ, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

Given is an exponential function is -

y = 3 × q⁵

The exponential function is written in the form abˣ.

Here, a is considered to be the initial value, b is considered to be the base and x represents the growth factor.

So, the initial or starting value in function y = 3 × q⁵ is -

a = 3

Hence, the starting value is 3.
