Activity 1: Obtain the differential equation of y = At^x, where A is a constant. To find the differential equation, we need to differentiate y with respect to t. Assuming A is a constant and x is a function of t, we can use the chain rule to differentiate y = At^x.

dy/dt = d(A\(t^x\))/dt

Applying the chain rule, we have:

dy/dt = d(A\(t^x\))/dx * dx/dt

Since x is a function of t, dx/dt represents the derivative of x with respect to t. To find dx/dt, we need more information about the function x(t).

Without further information about the relationship between x and t, we cannot determine the exact differential equation. The form of the differential equation will depend on the specific relationship between x and t.

Activity 3: Prove that y = \(4e^{(Ax + B)\), where A and B are constants, is a solution of the differential equation y'' - 25y = 0. To prove that y = \(e^{(Ax + B)\) is a solution of the given differential equation, we need to substitute y into the differential equation and verify that it satisfies the equation. First, let's calculate the first and second derivatives of y with respect to x:

dy/dx =\(4Ae^{(Ax + B)\)

\(d^2y/dx^2 = 4A^2e^{(Ax + B)\)

Now, substitute y, dy/dx, and \(d^2y/dx^2\) into the differential equation:

\(d^2y/dx^2 - 25y = 4A^{2e}^{(Ax + B)} - 25(4e^{(Ax + B)})\)

Simplifying the expression, we have:

\(4A^2e^(Ax + B) - 100e^{(Ax + B)\)

Factoring out the common term \(e^{(Ax + B)\), we get:

\((4A^2 - 100)e^{(Ax + B)\)

For the equation to be satisfied, the expression inside the parentheses must be equal to zero:

\(4A^2 - 100 = 0\)

Solving this equation, we find that A = ±5.

Therefore, for A = ±5, the function \(y = 4e^{(Ax + B)\) is a solution of the differential equation y'' - 25y = 0.

Given:

A geometric figure.

To find:

The point of tangency in the given figure.

Solution:

We know that, the point of tangency is a point where the tangent line touches the curve.

From the given figure it is clear that, two lines touch the circle at R and Z.

These two lines are tangent and they touch the curve at points R and Z. So, R and Z are point of tangency.

Therefore, the correct option is C.

The minimum surface area for the rectangular container is \(588cm^{2}\).

A solid object's surface area is a measurement of the overall space that the object's surface takes up.  Compared to the definition of the arc length of a one-dimensional curve or the definition of the surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces, the mathematical definition of surface area in the presence of curved surfaces is much more complex.

Let s be the side of the square base and h be the height.

Surface Area=\(s^{2}+4sh\)

Volume=\(s^{2}h\)

According to the question,

\(s^{2}h=1372\\ h=\frac{1372}{s^{2} }\)

So, surface area=\(s^{2} +4s(\frac{1372}{s^{2} })\)

                          =\(s^{2}+\frac{5488}{s}\)

Differentiate with respect to s,

Surface area=\(2s-\frac{5488}{s^{2} }\)

Now, \(2s-\frac{5488}{s^{2} }=0\)

\(2s=\frac{5488}{s^{2} } \\2s^{3}=5488\\ s^{3}=2744\\ s=14\)

Find the value of h from the volume.

\(14*14*h=1372\\h=\frac{1372}{14*14}\\ h=7\)

Thus, the minimum surface area=\(14^{2}+4*14*7\)

                                                      =\(588cm^{2}\)

Answer:

13/8, 13 to 8, 13:8

Step-by-step explanation:

if they won 50 more than they lost and won a total of 130 games, this means they lost 80 games (130-50=80). we can then write this as 130:80, which simplifies to 13:8

Answer:

The answers are 13/8, 13 to 8, 13:8.

Step-by-step explanation:

Since Frederico's team won 50 more games than they lost, and the won 130 games, then you would subtract the two numbers to find their losses:

130 - 50 = 80

The ratio of there wins to losses is 130 to 80.

Then you need to simplify this answer, which would make the ratio 13 to 8.

Three ways to write this are 13/8, 13 to 8, 13:8.

Step-by-step explanation:

To find the probability of the interval (-0.15 < z < 2.67) in a standard normal distribution, we can use the cumulative distribution function (CDF) of the standard normal distribution.

The CDF gives the probability that a standard normal random variable is less than or equal to a given value. In this case, we need to find the probability that z is less than or equal to 2.67 and subtract the probability that z is less than or equal to -0.15.

Using a standard normal distribution table or a statistical calculator, we can find the corresponding probabilities:

P(z < 2.67) ≈ 0.9960

P(z < -0.15) ≈ 0.4404

To find the probability of the interval (-0.15 < z < 2.67), we subtract the probability of z < -0.15 from the probability of z < 2.67:

P(-0.15 < z < 2.67) ≈ P(z < 2.67) - P(z < -0.15)

≈ 0.9960 - 0.4404

≈ 0.5556

Therefore, the probability of the interval (-0.15 < z < 2.67) in a standard normal distribution is approximately 0.5556.

Answer:ITS A

Step-by-step explanation:

The coordinate of the image point A (-1, 4).

In mathematics, a translation is an up, down, left, or right movement of shapes. Because the translated shapes appear to be identically similar in size to the original ones, they are congruent with one another.

The Rule of Translation of points is given by (x, y) → (x ± h, y ± k)

where the horizontal and vertical shiftings are h units and k units, respectively.

Given that

The image point of A after a translation right 4 units and up 4 units is the point B

Let A(x, y) be the point that translated to right 4 units and up 4 units

According to the given formula

(x, y) → (x ± h, y ± k)

Since the point is translated to right and up

=> (x, y) → (x + h, y + k)  

=> (x, y) → (x + 4, y + 4)

From the given data the final point is B(3, 8)

=> (x + 4, y + 4) = (3, 8)  

=> x + 4 = 3  and  y + 4 = 8

=> x + 4 = 3      

=> x = 3 - 4 = -1

=> x = -`1          

=> y + 4 = 8  

=> y = 8 - 4

=> y = 4  

Therefore,

The coordinate of the image point A (-1, 4).

The scale factor of dilation can be found by using the formula\((x_0=\frac{kx_1-x_2}{k-1}, y_0=\frac{ky_1-y_2}{k-1})\).

What is dilation?

A dilation is a transformation that creates an image that has the same shape as the original but is larger.

• An enlargement is a dilation that produces a larger image.

• A reduction is a dilation that produces a smaller image.

• A dilation expands or contracts the original figure.

A dilation is a stretch or a shrink in the size and location of a figure or point.

The scale factor in a dilation is the amount by which the figure is stretched or shrunk.

The center of dilation is a reference point used to appropriately scale the dilation of a figure. Given a point on the pre-image, \((x_1, y_1)\)and a corresponding point on the dilated image \((x_2, y_2)\)and the scale factor,

k, the location of the center of dilation, \((x_0,y_0)\) is

\((x_0=\frac{kx_1-x_2}{k-1}, y_0=\frac{ky_1-y_2}{k-1})\)

Hence, the scale factor of dilation can be found by using the formula\((x_0=\frac{kx_1-x_2}{k-1}, y_0=\frac{ky_1-y_2}{k-1})\).

The solution of the DTDS is xn = (0.63)^n * 41 grams, where n represents time in hours.

a) The updating function f(x) for the discrete time dynamical system (DTDS) can be derived from the given information that the body eliminates 37% of the alcohol present in the body per hour.

Since 37% of the alcohol is eliminated, the amount remaining after one hour can be calculated by subtracting 37% of the current amount from the current amount. This can be expressed as:

f(x) = x - 0.37x

Simplifying the equation:

f(x) = 0.63x

b) The initial condition for the DTDS is given as Peter having 41 grams of alcohol in his body after consuming three alcoholic drinks. Therefore, the initial condition is:

x0 = 41 grams

c) To find the solution of the DTDS with the given initial condition, we can use the updating function f(x) and iterate it over time.

For n hours, the solution is given by:

xn = f^n(x0)

Applying the updating function f(x) repeatedly for n times:

xn = f(f(f(...f(x0))))

In this case, since the function f(x) is f(x) = 0.63x, the solution can be written as:

xn = (0.63)^n * x0

Substituting the initial condition x0 = 41 grams, the solution becomes:

xn = (0.63)^n * 41 grams

200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.

Forecasted values are as follows: 1,500 and 1,400

Values in actuality: 1,200 and 1,500

Absolute differences:

|1,500 - 1,200| = 300

|1,400 - 1,500| = 100

Now, we calculate the MAD:

MAD = (300 + 100) / 2 = 400 / 2 = 200

Therefore, 200 is the mean absolute deviation. Therefore, choice three (200) is the right one.
