The value of y'(3) is 4.

To find y'(3) by implicit differentiation, we differentiate both sides of the given equation with respect to x. Let's differentiate each term:

d/dx (5x^2) + d/dx (3x) + d/dx (xy) = d/dx (3)

Applying the power rule and product rule, we get:

10x + 3 + y + x(dy/dx) = 0

Rearranging the equation, we have:

x(dy/dx) = -10x - y - 3

To find y'(3), we substitute x = 3 into the equation:

3(dy/dx) = -10(3) - y - 3

3(dy/dx) = -30 - y - 3

3(dy/dx) = -33 - y

Now, we can substitute y(3) = -17 into the equation:

3(dy/dx) = -33 - (-17)

3(dy/dx) = -33 + 17

3(dy/dx) = -16

dy/dx = -16/3

y'(3) = -16/3

Therefore, the value of y'(3) is -16/3 or approximately -5.333.

To find the equation of the tangent line to the graph at point (3, -17), we can use the point-slope form of a linear equation:

y - y₁ = m(x - x₁)

Substituting the values of the point (3, -17) and the slope y'(3) = -16/3, we have:

y - (-17) = (-16/3)(x - 3)

y + 17 = (-16/3)(x - 3)

Simplifying and rearranging the equation, we get:

y = (-16/3)(x - 3) - 17

y = (-16/3)x + 16 + 1 - 17

y = (-16/3)x

Therefore, the equation of the tangent line to the graph at the point (3, -17) is y = (-16/3)x.

The product rule of differentiation allows us to differentiate h(x) from f(x) using the product rule of differentiation. This means that h(x) = 9x2f(x)+3x3f(x) and h′(x) = 3x3f(x)+9x2f(x).So, Correct option is B.

Given that h(x)=3x3f(x) and we need to find h′(x).We know that if f(x) is an unspecified differentiable function, then h(x) can be differentiated using the product rule of differentiation.

Hence, f'(x) = [tex](x * cos(x) - sin(x)) / (x^2), and f'(c) = 9(π/6 - √3/2) / π^2[/tex]  when c = π/3. To find the derivative of the function f(x) = sin(x)/x and the value of f'(c) when c = π/3, we'll differentiate the function using the quotient rule.

The quotient rule states that for a function of the form f(x) = g(x)/h(x), the derivative is given by f'(x) = (g'(x) * h(x) - g(x) * h'(x)) / (h(x))^2.

Applying the quotient rule to f(x) = sin(x)/x, we have:

g(x) = sin(x)

h(x) = x

g'(x) = cos(x)   (derivative of sin(x))

h'(x) = 1        (derivative of x)

Now we can calculate f'(x) using the quotient rule:

f'(x) = (cos(x) * x - sin(x) * 1) / [tex](x^2)[/tex]

     = (x * cos(x) - sin(x)) / [tex](x^2)[/tex]

To find f'(c) when c = π/3, we substitute c into f'(x):

f'(c) = (c * cos(c) - sin(c)) / [tex](c^2)[/tex]

     = ((π/3) * cos(π/3) - sin(π/3)) / [tex]((π/3)^2)[/tex]

Simplifying further:

f'(c) = ((π/3) * (1/2) - √3/2) / [tex]((π/3)^2)[/tex]

    [tex]= (π/6 - √3/2) / (π^2/9)[/tex]

     [tex]= 9(π/6 - √3/2) / π^2[/tex]

Hence, [tex]f'(x) = (x * cos(x) - sin(x)) / (x^2), and f'(c) = 9(π/6 - √3/2) / π^2[/tex]when c = π/3.

The exact answer to the integral ∫e^(3√s)/√s ds is (2/9) e^(3√s) (3√s - 1) + C.To solve the integral ∫e^(3√s)/√s ds, we can use a substitution. Let u = √s, then du = (1/2√s) ds. Rearranging, we have 2√s du = ds.

Now, we can rewrite the integral in terms of u:

∫e^(3√s)/√s ds = ∫e^(3u) (2√s du)

Substituting back s = u^2, and ds = 2√s du, we get:

∫e^(3u) (2√s du) = ∫e^(3u) (2u) du

Now, we can evaluate this integral:

∫e^(3u) (2u) du = 2 ∫u e^(3u) du

To integrate this expression, we can use integration by parts. Let u = u and dv = e^(3u) du. Then, du = du and v = (1/3) e^(3u).

Applying integration by parts, we have:

2 ∫u e^(3u) du = 2 (u * (1/3) e^(3u) - ∫(1/3) e^(3u) du)

Simplifying the right-hand side, we have:

2 (u * (1/3) e^(3u) - (1/3) ∫e^(3u) du)

Integrating ∫e^(3u) du gives us (1/3) e^(3u):

2 (u * (1/3) e^(3u) - (1/3) * (1/3) e^(3u) + C)

Combining terms and simplifying, we obtain:

(2/9) e^(3u) (3u - 1) + C

Finally, substituting back u = √s, we have:

(2/9) e^(3√s) (3√s - 1) + C

Therefore, the exact answer to the integral ∫e^(3√s)/√s ds is (2/9) e^(3√s) (3√s - 1) + C.

c) The definite integral for the area of the upper half of the curve can be found by integrating the function y = √(9 - (9/4)x^2) with respect to x over the appropriate interval. To determine the interval, we solve the equation x^2/4 + y^2/9 = 1 for x:

x^2/4 = 1 - y^2/9

x^2 = 4 - (4/9)y^2

Taking the square root of both sides, we have:

x = ±√(4 - (4/9)y^2)

Since we are interested in the upper half, we take the positive square root:

x = √(4 - (4/9)y^2)

The interval for the definite integral is from x = 0 to x = 2. Thus, the definite integral representing the area is:

∫[0,2] √(9 - (9/4)x^2) dx

d) When revolving the function along the x-axis, we can use the method of cylindrical shells to find the volume. The definite integral representing the volume is:

∫[0,2] 2πx√(9 - (9/4)x^2) dx

e) To work out the definite integral for the volume, we evaluate ∫[0,2] 2πx√(9 - (9/4)x^2) dx. The integration steps involve substituting u = 9 - (9/4)x^2 and making appropriate substitutions to simplify the integral. The specific steps will depend on the chosen method of integration, such as u-substitution or trigonometric substitution.

f) When revolving the function along the y-axis, we again use the method of cylindrical shells to find the volume. The definite integral representing the volume is:

∫[0,3] 2πy(x) dx

where y(x) is the positive square root of the equation x^2/4 + y^2/9 = 1:

y(x) = √(9 - (9/4)x^2)

The interval for the definite integral is from y = 0 to y = 3.

g) To work out the definite integral for the volume, we evaluate ∫[0,3] 2π√(9 - (9/4)x^2) dx. The integration steps involve making appropriate substitutions or employing techniques like trigonometric substitution, depending on the chosen method of integration. The specific steps will be determined by the approach taken to solve the integral.

The flux of F = 5j across the curve C: y = 0, 0 ≤ x ≤ 3 is 15 units.

To compute the flux of a vector field across a curve, we need to evaluate the dot product of the vector field and the tangent vector of the curve, integrated over the length of the curve.

Given the vector field F = 5j and the curve C: y = 0, 0 ≤ x ≤ 3, we need to find the tangent vector of the curve. Since the curve is a straight line along the x-axis, the tangent vector will be constant and parallel to the x-axis.

The tangent vector is given by T = i.

Now, we take the dot product of the vector field F and the tangent vector:

F · T = (0)i + (5j) · (i)

= 0 + 0 + 0 + 5(1)

= 5

To integrate the dot product over the length of the curve, we need to parameterize the curve. Since the curve is a straight line along the x-axis, we can parameterize it as r(t) = ti + 0j, where t varies from 0 to 3.

The length of the curve is given by the definite integral:

∫[0,3] √((dx/dt)^2 + (dy/dt)^2) dt

Since dy/dt = 0, the integral simplifies to:

∫[0,3] √((dx/dt)^2) dt

= ∫[0,3] √(1^2) dt

= ∫[0,3] dt

= [t] [0,3]

= 3 - 0

= 3

Therefore, the flux of F across the curve C: y = 0, 0 ≤ x ≤ 3 is given by the dot product multiplied by the length of the curve:

Flux = F · T × Length of C

= 5 × 3

= 15 units.

The height of water in the cylinder for the second rain gauge, with an opening 10 times the area of the first rain gauge, is 1 cm.

In the second rain gauge, with an opening 10 times the area of the first rain gauge (B: 200 cm^2), and a collection cylinder with the same opening as the rain gauge in (A: 20 cm^2), we need to determine the height of water in the cylinder for a rainstorm of 10 cm.

To find the height of water in the cylinder, we can use the principle of conservation of volume. The volume of water collected in both rain gauges should be the same since it is from the same rainstorm.

The volume of water collected in the first rain gauge (A) can be calculated using the formula:

Volume = Area * Height

Given that the area of the opening is 20 cm^2 and the height of the water collected is 10 cm, we can find the volume of water collected in rain gauge (A).

Now, let's calculate the volume of water collected in the second rain gauge (B). Since the opening is 10 times the area of the first rain gauge (200 cm^2), we need to find the height of water in the cylinder to maintain the same volume as in rain gauge (A).

By using the formula Volume = Area * Height, we can rearrange it to solve for the height:

Height = Volume / Area

Substituting the volume of water collected in rain gauge (A) and the area of the opening in rain gauge (B), we can calculate the height of water in the cylinder for the second rain gauge.

By performing the calculations, we find that the height of water in the cylinder for the same rainstorm of 10 cm is XXX cm in the second rain gauge.

The derivatives are R'(t) = 2i + 6tj + 9t²k and R''(t) = 6j + 18tk.

To find the derivative of R(t), we differentiate each component of the vector separately:

R(t) = 2ti + 3t²j + 3t³k

Taking the derivative of each component:

R'(t) = (d/dt)(2ti) + (d/dt)(3t²j) + (d/dt)(3t³k)

= 2i + (d/dt)(3t²)j + (d/dt)(3t³)k

= 2i + 6tj + 9t²k

Therefore, R'(t) = 2i + 6tj + 9t²k.

To find the second derivative of R(t), we differentiate each component of R'(t):

R''(t) = (d/dt)(2i) + (d/dt)(6tj) + (d/dt)(9t²k)

= 0i + 6j + (d/dt)(9t²)k

= 6j + (d/dt)(9t²)k

= 6j + 18tk

Therefore, R''(t) = 6j + 18tk.

In the given figure, if [tex]\(HC^2 = 3\sqrt{3}\)[/tex], we can use the Pythagorean theorem to find the value of AB + AC.

According to the Pythagorean theorem, in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, triangle ABC is a right triangle, with AB and AC as the two sides adjacent to the right angle at point A.

Since [tex]\(HC^2 = 3\sqrt{3}\)[/tex], we have:

Let's find the second order Taylor formula for (x,y) = (5x + 4y)^2 at 0 = (0,0).

Note that ℝ2(0,) = 0

in this case. To begin with, we know that the second order Taylor formula for a function f(x,y) is given by the expression

f(x, y) ≈ f(a, b) + ∂f/∂x∣∣(a, b) (x − a) + ∂f/∂y

(a, b) (y − b) + (1/2)[∂2f/∂x²

(a, b)(x − a)² + 2∂²f/∂x∂y

(a, b)(x − a)(y − b) + ∂²f/∂y²

(a, b)(y − b)²]

Applying this formula to the given function f(x,y) = (5x + 4y)²,

we have;

f(x, y) = f(0, 0) + ∂f/∂x

(0, 0) (x − 0) + ∂f/∂y

(0, 0) (y − 0) + (1/2)[∂²f/∂x²

(0, 0)(x − 0)² + 2∂²f/∂x∂y

(0, 0)(x − 0)(y − 0) + ∂²f/∂y²

(0, 0)(y − 0)²]f(0, 0)

= (5 × 0 + 4 × 0)²

= 0∂f/∂x = 2(5x + 4y)(5)

[tex]= 50x + 40y; ∂f/∂x∣∣(0, 0) \\= 0∂f/∂y \\= 2(5x + 4y)(4) \\= 40x + 32y; ∂f/∂y∣∣(0, 0) \\= 0∂²f/∂x²[/tex]

[tex]= 50; ∂²f/∂x²∣∣(0, 0)[/tex]

= [tex]40; ∂²f/∂x∂y∣∣(0, 0) = 40[/tex]

Substituting these values into the second order Taylor formula for (x,y) = (5x + 4y)² at 0 = (0,0),

we have;

f(x, y) ≈ f(0, 0) + ∂f/∂x

(0, 0) x + ∂f/∂y

(0, 0) y + (1/2)[∂²f/∂x²

(0, 0)x² + 2∂²f/∂x∂y

(0, 0)xy + ∂²f/∂y²

(0, 0)y²]f(x, y) ≈ 0 + 0 + 0 + (1/2)[50x² + 80xy + 32y²]f(x, y) ≈ 25x² + 40xy + 16y²

Therefore, the second order Taylor formula for

(x,y) = (5x + 4y)² at 0 = (0,0) is given by (ℎ₁, ℎ₂) = (25x² + 40xy + 16y², 0). The answer is (ℎ₁, ℎ₂) = (25x² + 40xy + 16y², 0).

Answer:29/9

Step-by-step explanation:

a. The PDF of Y=X is

fY(y) = (1/2) * fZ(y/2)

b. The PDF of Y=X² is

fY(y) = (1/4πy)^(1/2) * exp(-y/8).

a. PDF of Y=X)

Given, X follows a Gaussian distribution with zero mean and variance equal to 4.

Now, the PDF of Y=X will be given by the formula,

fY(y)=fX(x)|dx/dy|

Substituting Y=X, we get,

X = Y

dx/dy = 1

Hence,

fY(y) = fX(y)

= (1/2πσ²)^(1/2) * exp(-y²/2σ²)

fY(y) = (1/2π4)^(1/2) * exp(-y²/8)

fY(y) = (1/4π)^(1/2) * exp(-y²/8)

Also, we know that the PDF of standard normal distribution,

fZ(z) = (1/2π)^(1/2) * exp(-z²/2)

Hence,

fY(y) = (1/2) * fZ(y/2)

Therefore, the PDF of Y=X is

fY(y) = (1/2) * fZ(y/2)

b. PDF of Y=X²

Given, X follows a Gaussian distribution with zero mean and variance equal to 4.

Now, the PDF of Y=X² will be given by the formula,

fY(y)=fX(x)|dx/dy|

Substituting Y=X², we get,

X = Y^(1/2)dx/dy

= 1/(2Y^(1/2))

Hence,

fY(y) = fX(y^(1/2)) * (1/(2y^(1/2)))

fY(y) = (1/2πσ²)^(1/2) * exp(-y/2σ²) * (1/(2y^(1/2)))

fY(y) = (1/4π)^(1/2) * exp(-y/8) * (1/(2y^(1/2)))

The lift equation provides a mathematical representation of the factors influencing lift. By understanding the variables in the lift equation and their effects, aircraft designers and pilots can optimize flight performance by adjusting variables such as the angle of attack, altitude, and velocity to achieve the desired lift characteristics for safe and efficient flight.

- Lift (L): Lift is the force generated by an airfoil or wing as a result of the pressure difference between the upper and lower surfaces of the wing.

- Coefficient of Lift (Cl): The coefficient of lift represents the lift characteristics of an airfoil or wing and is dependent on its shape and angle of attack.

- Air Density (ρ): Air density is a measure of the mass of air per unit volume and is affected by factors such as altitude, temperature, and humidity.

- Wing Area (A): Wing area refers to the total surface area of the wing exposed to the airflow.

- Velocity (V): Velocity is the speed of the aircraft relative to the air it is moving through.

- Coefficient of Lift (Cl): The shape of an airfoil or wing, as well as the angle of attack, affects the coefficient of lift. Changes in these variables can alter the lift generated by the wing.

- Air Density (ρ): Changes in air density, which can occur due to changes in altitude or temperature, directly affect the lift. Decreased air density reduces lift, while increased air density enhances lift.

- Wing Area (A): The size of the wing area affects the amount of lift generated. A larger wing area provides more surface for the air to act upon, resulting in increased lift.

- Velocity (V): The speed of the aircraft affects lift. As velocity increases, the lift generated by the wing also increases.

Changes During Flight:

During a flight, these variables can be changed through various means:

- Coefficient of Lift (Cl): The angle of attack can be adjusted using the aircraft's control surfaces, such as the elevators or flaps, to change the coefficient of lift.

- Air Density (ρ): Air density changes with altitude, so flying at different altitudes will result in different air densities and affect the lift.

- Wing Area (A): The wing area remains constant during a flight unless modifications are made to the aircraft's wings.

- Velocity (V): The velocity can be controlled by adjusting the thrust or power output of the aircraft's engines, altering the aircraft's speed.

The derivative of the function f(x) = x^6 * e^x is

f'(x) = e^x * (6 * x^5 + x^6).

To find the derivative of the function f(x) = x^6 * e^x, we can apply the product rule and the chain rule.

The product rule states that if we have two functions u(x) and v(x), the derivative of their product is given by:

(d/dx)(u(x) * v(x)) = u'(x) * v(x) + u(x) * v'(x)

In this case, u(x) = x^6 and

v(x) = e^x.

Applying the product rule, we have:

f'(x) = (d/dx)(x^6 * e^x)

= (d/dx)(x^6) * e^x + x^6 * (d/dx)(e^x)

The derivative of x^6 with respect to x can be found using the power rule, which states that the derivative of x^n with respect to x is given by:

(d/dx)(x^n) = n * x^(n-1)

Using this rule, we find:

(d/dx)(x^6) = 6 * x^(6-1)

= 6 * x^5

The derivative of e^x with respect to x is simply e^x.

Therefore, continuing with our calculations:

f'(x) = 6 * x^5 * e^x + x^6 * e^x

Simplifying the expression, we can factor out e^x:

f'(x) = e^x * (6 * x^5 + x^6)

Thus, the derivative of the function f(x) = x^6 * e^x is

f'(x) = e^x * (6 * x^5 + x^6).
