5. The solution to the differential equation (ex + y)dx + (2 + x + yey)dy = 0 with y(0) = 1 is y = 2e^(-x) – x – 1. 6. The solution to the differential equation (x + y)²dx + (2xy + x² – 1)dy = 0 with y(1) = 1 is y = x – 1.

5. To solve the differential equation (ex + y)dx + (2 + x + yey)dy = 0 with the initial condition y(0) = 1, we can use the method of exact differential equations. By identifying the integrating factor as e^(∫dy/(2+yey)), we can rewrite the equation as an exact differential. Solving the resulting equation yields the solution y = 2e^(-x) – x – 1.
To solve the differential equation (x + y)²dx + (2xy + x² – 1)dy = 0 with the initial condition y(1) = 1, we can use the method of separable variables. Rearranging the equation and integrating both sides with respect to x and y, we obtain the solution y = x – 1.
These solutions satisfy their respective initial conditions and represent the family of curves that satisfy the given differential equations.

Applying the area of the parallelogram formula, it can be concluded that the area is 56 square units.

The area of the parallelogram is the magnitude of the cross-product of the adjacent edges (base and height).

Given information:

A parallelogram is made up of 4 vertices: A(−3, 0), B(−1, 6), C(8, 5), and D(6, −1).

So first we find the adjacent edges as follows:

AB = B - A

     = ( (-1-(-3)) , (6-0) )

     = (2,6)

AD = D - A

     = ((6-(-3)) , (-1-0))

     = (9,-1)

We want to find the area of the parallelogram, we do the following step:

\(AB x AD = \left[\begin{array}{ccc}i&j&k\\2&6&0\\9&-1&0\end{array}\right]\)

               = i(0 - 0) + j(0 - 0) + k(-2 - 54)

               = -56k

The area of the parallelogram = | AB x AD |

                                                  = √(-56)²

                                                  = 56 square unit

0.5328 is the probability that a patient has total cholesterol between 180 and 190

We have, Mean value, μ = 200 mg/dl

Standard deviation, σ = 20 mg/dl

Let X be the random variable that represents the total cholesterol levels in the population, then the distribution of X is given as follows:

X ~ N(μ, σ^2)Here, X ~ N(200, 20^2)

Now, the probability that a patient has total cholesterol levels between 180 and 190 i.e.,P(180 < X < 190)

Using the Z-score standardization formula,

Z = (X - μ) / σ

Z-score for X = 180,

Z₁ = (180 - 200) / 20 ⇒ -1

Z-score for X = 190,

Z₂ = (190 - 200) / 20 ⇒ -0.5

Therefore, P(180 < X < 190) = P(-1 < Z < -0.5)

Now, we can use a standard normal distribution table to find this probability:

P(-1 < Z < -0.5) = Φ(-0.5) - Φ(-1) ⇒ 0.6915 - 0.1587 = 0.5328 (rounded to 4 decimal places)

Therefore, the probability that a patient has total cholesterol levels between 180 and 190 is 0.5328 (rounded to 4 decimal places).

Answer:

we have added 9/4 to both sides of the equation.

Step-by-step explanation:

The given equation is :

\(x^2+3x=6\)

Here, a = 1, b = 3 and c = 6

We should add (b/2)^2 to the both sides of the equation.

(b/2)^2 = (3/2)^2 = (9/4)

\(x^2+3x+\dfrac{9}{4}=6+\dfrac{9}{4}\\\\(x+\dfrac{3}{2})^2=\dfrac{33}{4}\\\\x+\dfrac{3}{2}=\pm \dfrac{\sqrt{33}}{2}\\\\x= +\dfrac{\sqrt{33}}{2}-\dfrac{3}{2}, -\dfrac{\sqrt{33}}{2}-\dfrac{3}{2}\\\\=1.37,-4.37\)

Hence, we have added 9/4 to both sides of the equation.

(d) f(x) = x + x is neither convex nor concave

(e) f(x) = x + x^4 is convex

(a) The function f(x) = 10x - x^2 is concave. To show this, we take the second derivative of f(x) which is -2, which is negative for all x. Since the second derivative is negative for all x, the function is concave.

(b) The function f(x) = x' + 6x^2 + 12x is convex. To show this, we take the second derivative of f(x) which is 12x + 2, which is positive for all x. Since the second derivative is positive for all x, the function is convex.

(c) The function f(x) = 2x - 3x^2 is concave. To show this, we take the second derivative of f(x) which is -6, which is negative for all x. Since the second derivative is negative for all x, the function is concave.

(d) The function f(x) = x + x is neither convex nor concave. To show this, we take the second derivative of f(x) which is 0, which is neither positive nor negative. Since the second derivative is neither positive nor negative, the function is neither convex nor concave.

(e) The function f(x) = x + x^4 is convex. To show this, we take the second derivative of f(x) which is 12x^2, which is positive for all x except 0. Since the second derivative is positive for all x except 0, the function is convex.

Answer:

Step-by-step explanation:

This is an arithmetic sequence.

Answer: 21

Step-by-step explanation:

The student's mean of the 8 numbers is 20; the total of the numbers will be

8 x 20 = 160

If we then replace the 17 with 25 the total rises to 168.

168 divided by 8 = 21

The maximum and minimum values of the function cannot be determined as it is. Therefore, the answer is not possible.

Let's find the maximum and minimum values of the function f(x,y,z)=3x-y-3z subject to the constraints:

Since the constraint is 0, then we can assume that:

Thus the constraint reduces to x+y = 4 and z = 2-2yThe function becomes

f(x,y,z)=3x-y-3z = 3x-y-3(2-2y) = 3x-7y+6

The objective is to find the minimum and maximum values of this function. We can use partial derivatives of f with respect to x and y.

∂f/∂x = 3, ∂f/∂y = -7

Since the partial derivative of f with respect to z is not included in the objective function, we need not bother about it. At a maximum or minimum value, the partial derivatives are zero.

Therefore, we can conclude that there is no maximum or minimum value of f(x,y,z).

The function which is in format f(x) =aˣ where a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).

Here,
To determine whether the data shows an exponential function, we need to check whether there is a constant ratio between successive y-values for a constant change in the x-value.

Looking at the table, we can see that:

When x increases by 3 units (from 3 to 6), y doubles (from 1 to 2).

When x increases by another 3 units (from 6 to 9), y doubles again (from 2 to 4).

When x increases by another 3 units (from 9 to 12), y doubles once more (from 4 to 8).

Therefore, there is a constant ratio of 2 between successive y-values for a constant change in the x-value of 3. This means that the data does show an exponential function.

Therefore, the radius of the container is approximately 5 centimeters.

Volume is a measure of the amount of space that a substance or object occupies in three-dimensional space. It is commonly expressed in units of cubic meters (m³) or cubic centimeters (cm³), although other units, such as liters (L) and gallons (gal), are also frequently used. The volume of an object or substance can be calculated by measuring its length, width, and height and multiplying these dimensions together. In some cases, volume can also be determined by displacement, as in the case of measuring the volume of a liquid by the amount of space it displaces when poured into a container.

by the question.

The volume of a cylindrical container is given by the formula:

V = πr²h

where V is the volume, r is the radius, and h is the height.

We are given that the volume is 314 cubic centimeters, and the height is 4 centimeters. Substituting these values into the formula, we get:

314 = πr² (4)

Simplifying, we get:

78.5 = πr²

Dividing both sides by π, we get:

r² ≈ 25

Taking the square root of both sides, we get:

r ≈ 5

With proper conclusion, we can say that the probability that Jones would get at least 20,000 additional miles out of the car is very low, almost negligible.

To find the probability that Jones would get at least 20,000 additional miles out of the car, we need to consider the distribution of the random variable.

In this case, the random variable represents the additional miles Jones would get out of the car, given that Smith claims it has been driven only 10,000 miles.
Given that the parameter is 20, we can assume that the random variable follows a Poisson distribution with parameter λ = 20.

The Poisson distribution is commonly used to model the number of events occurring in a fixed interval of time or space.

To find the probability that Jones would get at least 20,000 additional miles out of the car, we can use the cumulative distribution function (CDF) of the Poisson distribution. The CDF gives the probability that the random variable is less than or equal to a certain value. In this case, we want to find the probability that the random variable is greater than or equal to 20,000.

Using the Poisson CDF, we can calculate this probability. However, since the parameter is 20, the probability of getting at least 20,000 additional miles out of the car would be extremely low. It would be close to zero.

Therefore, with proper conclusion, we can say that the probability that Jones would get at least 20,000 additional miles out of the car is very low, almost negligible.
