The solution to the given initial value problem is \( y(x) = \frac{11}{4} + \frac{3}{4} \sin\left(\frac{x+2}{2}\right) \).

To solve the initial value problem, we can separate variables and integrate.

The differential equation can be rewritten as \( \frac{dy}{\sqrt{-2y+11}} = dx \). Integrating both sides gives us \( 2\sqrt{-2y+11} = x + C \), where \( C \) is the constant of integration.

Substituting the initial condition \( y(-2) = 1 \) gives us \( C = 3 \). Solving for \( y \), we have \( \sqrt{-2y+11} = \frac{x+3}{2} \).

Squaring both sides and simplifying yields \( y = \frac{11}{4} + \frac{3}{4} \sin\left(\frac{x+2}{2}\right) \).

Thus, the solution to the initial value problem is \( y(x) = \frac{11}{4} + \frac{3}{4} \sin\left(\frac{x+2}{2}\right) \).

Since the algae grow exponentially with doubling time of 4 days, then the population will be quadruple in size in 8 days and will be triple in size in  6.34 days.

The easiest way is to consider the situation as a geometric sequence. If the population doubles its size in 4 days, then it will be quadruple in:

2 x 4 days = 8 days.

In general, we can use the growth formula:

P(t) = Po . 2^(t/Td)

Where:

P(t) = population at time t

Po = initial population

Td = doubling time

Parameters given:

Td = 4 days

P(t) = 3Po

Plug those parameters into the formula:

3 Po = Po . 2^(t/4)

3 = 2^(t/4)

log 3 = (t/4) log 2

t = 4 . log 3 / log 2 = 6.34 days.

Answer:

Surface Area =237.5

Answer:237.5

Step-by-step explanation:

The volume of a pyramid with a square base, where the perimeter of the base is 4.7 cm and the height of the pyramid is 4.7 cm, is 2.2 cm³.

The volume of a pyramid is calculated by dividing the area of the base by three and multiplying by the height. In this case, the area of the base is 22.09 square centimeters and the height is 4.7 cm. Therefore, the volume is 2.2 cubic centimeters.

The area of the base can be calculated by multiplying the length of one side of the square by itself. In this case, the length of one side of the square is 4.7 cm. Therefore, the area of the base is 4.7 * 4.7 = 22.09 square centimeters.

The height of the pyramid is the distance from the apex of the pyramid to the center of the base. In this case, the height is 4.7 cm.

By plugging these values into the formula for the volume of a pyramid, we get V = 1/3 * 22.09 * 4.7 = 2.2 cubic centimeters.

The answer is rounded to the nearest tenth of a cubic centimeter, which is 2.2 cubic centimeters.

To find the partial derivatives ∂u/∂z and ∂v/∂z, we can use the chain rule. Given that z = (6x + y)e^x, where x = ln(u) and y = v, we differentiate z with respect to u and v separately to find the partial derivatives.

To find ∂u/∂z, we need to find the derivative of u with respect to z. We can use the chain rule to do this. Since x = ln(u), we have u = \(e^x\). Taking the derivative of both sides with respect to z, we have:

du/dz = (du/dx)(dx/dz).

From the given equation x = ln(u), we can differentiate both sides with respect to z to get:

(1/u)(du/dz) = (1/x)(dx/dz).

Simplifying further, we have:

(du/dz) = (u/x)(dx/dz).

Substituting x = ln(u), we get:

(du/dz) = (u/ln(u))(dx/dz).

Similarly, to find ∂v/∂z, we differentiate v with respect to z. Since y = v, we have:

dv/dz = (dv/dy)(dy/dz).

Since dy/dz is simply 1, we have:

dv/dz = dv/dy.

Therefore, ∂u/∂z = (u/ln(u))(dx/dz) and ∂v/∂z = dv/dy. The exact values of these derivatives depend on the specific values of u, x, and v, which are not provided in the given question

The value of the Nintendo after 35 years is $2455

Since the formula f(x) = 3x² - 40x + 180 predicts the value of the Nintendo x years after 1986.

Since we require the value in 2021, x years after 1986 is 2021 - 1986 = 35 years.

Substituting x = 35 into the equation, we have

f(x) = 3x² - 40x + 180

f(x) = 3(35)² - 40(35) + 180

f(x) = 3(1225) - 40(35) + 180

f(x) = 3675 - 1400 + 180

f(x) = 2275 + 180

f(x) = 2455

So, the value of the Nintendo after 35 years is $2455

The angle that the ramp makes with the ground rounded off to two decimal places is 10.48°.

What is trigonometry?
The study of the relationship between the sides and angles of the right-angle triangle is essentially the focus of the field of mathematics known as "trigonometry". Therefore, employing trigonometric formulas, functions, or trigonometric identities can be helpful in determining the missing or unknown angles or sides of a right triangle. Angles in trigonometry can be expressed as either degrees or radians.

Given, the length of the ramp = h = 17 feet
Height at which ramp is placed on truck = p = 4 feet
Let the angle that the ramp makes with the ground = ∅
Taking the length and height of ramp as basis, on assuming a right triangle with the length as hypotenuse and the height as perpendicular, we have:
sin ∅ = Perpendicular/Hypotenuse = h / p = 17/4 = 4.25
⇒ ∅ = sin⁻¹ (4.25) ⇒ ∅ = 10.48°
Thus, the angle that the ramp makes with the ground rounded off to two decimal places is 10.48°.

Volume of 19.6 g of a liquid that has a density of 0.967 g/ml is 20.3

Volume and density are connected by a particular substance's mass. The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d).

Density decreases when volume increases without accompanying increases in mass.

here,

Density = mass/volume

or, Volume = mass/density

or, volume = 1.96g/0.967 g/ml

or, volume = 20.268 ml (nearly equal to 20.3)

so, Volume of 19.6 g of a liquid that has a density of 0.967 g/ml is 20.3

The change in profit (ΔP) when the number of units (Δx) increases by 5, based on the given marginal profit function, is -18331.50

To find the change in profit (ΔP) when the number of units (Δx) increases by 5.

we need to evaluate the marginal profit function and multiply it by Δx.

The marginal profit function is given by dP/dx = 12.1(60 - 3x).

We are given the value of x as 121, so we can substitute it into the marginal profit function to find the marginal profit at that point.

dP/dx = 12.1(60 - 3(121))

= 12.1(60 - 363)

= 12.1(-303)

= -3666.3

Now, we can calculate the change in profit (ΔP) by multiplying the marginal profit by Δx, which is 5 in this case.

ΔP = dP/dx×Δx

= -3666.3 × 5

= -18331.5

The probability of getting a heart on the fourth card but not before that is 0.2278

The probability of getting a heart on the fourth card can be calculated by multiplying the probability of not getting a heart in the first three cards by the probability of getting a heart on the fourth card.

The probability of not getting a heart in the first three cards can be calculated as follows:

(39/52) * (38/51) * (37/50) = 0.862

where 39/52 is the probability of not getting a heart on the first card, 38/51 is the probability of not getting a heart on the second card (given that no heart was drawn in the first card), and 37/50 is the probability of not getting a heart on the third card (given that no heart was drawn in the first two cards).

The probability of getting a heart on the fourth card can be calculated as follows:

13/49 = 0.265

where 13/49 is the probability of getting a heart on the fourth card (given that no heart was drawn in the first three cards).

So, the probability of getting a heart on the fourth card, but not before, can be calculated as:

0.862 * 0.265 = 0.2278

So, the chance of getting a heart on the fourth card, but not before, is approximately 22.78%.

Transition matrix is called a doubly stochastic matrix (if sum of each rows and columns is 1 ).

We can see that the distribution of doubly stochastic matrix for all finite dimensional has Uniform stationary distribution.

Doubly Stochastic Matrix

A transition random matrix P is defined as a dual random matrix if the sum of the rows and columns is one.

Therefore, for each column j of the doubly random matrix, let ∑ ipᵢⱼ = 1. Suppose the distribution π on S also has π₁ = π if the Markov chain starts with the initial distribution π₀ = π. That is, if the distribution at time 0 is π, the distribution of π remains 1, and this π is said to be stationary.

Example: A uniform distribution [[π(i) = 1/N for all i]] is stationary if the N × N stochastic transition matrix P is symmetric. More generally, the uniform distribution is stationary if the matrix P is doubly stochastic, i.e. the columns of P sum to 1 (we already know that the rows of P sum to all 1). are available). It is easy to see that when πn approaches a limiting distribution as n → ∞, this limiting distribution must be stationary. To see this, assuming lim n→∞ πn = π' , and n → ∞ in the equation πₙ₊₁ = πₙP, we get π = π'P. This shows that π' is stationary. So , the arguments given pass clearly and simply when the state space is finite.Hence, the required results is achieved .
