The value of c is -10/3. This can be answered by the concept of Differentiation.

To find the values of c for which the parabolas y = 9x² and x = c + 3y² intersect at right angles, we need to consider the slopes of the tangent lines at the intersection points.

First, let's find the derivatives of both functions to get the slopes:

For y = 9x², let's find dy/dx:
dy/dx = 18x

For x = c + 3y², let's find dx/dy:
dx/dy = 1 / (6y)

At the intersection points, we have:
9x² = y
c + 3y² = x

Since the tangent lines are perpendicular, their slopes multiply to -1:
(18x)(1 / (6y)) = -1

Now, substitute y = 9x² into the equation:
(18x)(1 / (6 × 9x²)) = -1
(18x)(1 / (54x²)) = -1
(1 / (3x)) = -1

Solving for x, we get x = -1/3.

Now substitute this value of x into the equation for y:
y = 9(-1/3)²
y = 9(1/9)
y = 1

So the intersection point is (-1/3, 1). Now substitute the value of y back into the equation for x to find c:
-1/3 = c + 3(1²)
-1/3 = c + 3
c = -1/3 - 3
c = -10/3

Therefore, the value of c is -10/3.

It would take Deshaun 5 hours to drive 335 miles at the same rate.

The SI unit of speed is m/s, and speed is defined as the ratio of distance to time. It is the shift in an object's location with regard to time.

We can use the formula:

rate = distance / time

to solve the problem. The rate is constant, so we can use it to find the time for a different distance.

First, we find Deshaun's rate:

rate = distance / time = 469 miles / 7 hours = 67 miles per hour

Now we can use this rate to find the time it would take to drive 335 miles:

time = distance / rate = 335 miles / 67 miles per hour

time = 5 hours

Therefore, it would take Deshaun 5 hours to drive 335 miles at the same rate.

The probability that you win is given as follows:

25/81.

Hence it is not true that you are more likely to win, as the probability of winning is less than 50%. Even tough there are more odd numbers than even number, you need two odd numbers for the product to generate an odd number.

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

For the product of two numbers, we have that:

5(1, 3, 5, 7 and 9) out of the 9 numbers, are odd, hence the probability of choosing two odd numbers is given as follows;

After continuing this process recursively until all integers are placed in the MIN HEAP. Using this method, we can see that there is only one possible MIN HEAP that can be made using the given set of integers. Therefore, the answer of the Binary Tree is 1.

Given the set of integers {88, 2, 9, 36}, there are 3 different Min Heaps that can be made using these integers. Min Heap is a binary tree where the parent node has a value less than or equal to its child nodes.

To determine the number of different MIN HEAPs that can be made using the set of integers {88, 2, 9, 36}, we can use the formula for the number of distinct permutations of n elements, which is n!. However, we need to take into account that MIN HEAP has a specific structure where the parent node is always smaller than its children nodes.

Then, we can choose the next smallest integer (9 or 36) as the left child of 2, and the remaining integer as the right child of 2. We can continue this process recursively until all integers are placed in the MIN HEAP.

b. P(Z ≤ -2.36) = 0.0091
c. P(0 ≤ Z ≤ 1.07) = 0.3577


1. To find the probabilities, you need to reference a standard normal (z) table.

2. For a. P(Z > 1.02), look up 1.02 on the z table. The corresponding value is 0.8461. Since the question asks for P(Z > 1.02), subtract the value from 1: 1 - 0.8461 = 0.1539.

3. For b. P(Z ≤ -2.36), look up -2.36 on the z table. The corresponding value is 0.0091. Since the question asks for P(Z ≤ -2.36), the value is already correct: 0.0091.

4. For c. P(0 ≤ Z ≤ 1.07), look up 1.07 on the z table. The corresponding value is 0.8577. Since the question asks for P(0 ≤ Z ≤ 1.07), subtract 0.5 (value for Z = 0): 0.8577 - 0.5 = 0.3577.

The equation to compute the area A of the circle is: [tex]A = π(r^2 - r0^2) + A0[/tex] where r0 is the initial radius and A0 is the initial area.

The equation to compute the area A of a circle with radius r is [tex]A = πr^2[/tex].

Using this equation and the given information that the radius is increasing at a rate of centimeters per second, we can write:

[tex]\frac{dA}dt} = 2rπ \frac{dr}{dt}[/tex]

where dA/dt represents the rate of change of area with respect to time, and [tex]\frac{dr}{dt}[/tex] represents the rate of change of radius with respect to time.

Part 1:

If we want to find the area of the circle at a specific time t, we can integrate both sides of the equation with respect to time:

[tex]\int\limits dA= \int\limits 2πr \frac{dr}{dt}  \, dt[/tex]

Integrating both sides gives:

[tex]A = πr^2 + C[/tex]

where C is the constant of integration. Since we are given the initial radius, we can use it to find the value of C:

When t = 0, r = r0

[tex]A = πr0^2 + C[/tex]

Therefore, [tex]C = A - πr0^2[/tex]

Substituting this value of C back into the equation gives:

[tex]A = πr^2 + A - πr0^2[/tex]

Simplifying gives:

[tex]A =π(r^2 - r0^2) + A0[/tex]

where A0 is the initial area of the circle.

Therefore, the equation to compute the area A of the circle is:

[tex]A = π(r^2 - r0^2) + A0[/tex]

where r0 is the initial radius and A0 is the initial area.

The area of the region bounded by the curve r = 2sin(θ) in the sector 0≤θ≤π is π/2 square units.

The curve given by the polar equation r = 2sin(θ) is a sinusoidal spiral that starts at the origin, goes out to a maximum distance of 2 units, and then spirals back into the origin as θ increases from 0 to 2π. The sector 0≤θ≤π is half of this spiral, so we can find its area by integrating the area element dA = 1/2 r^2 dθ over this sector

A = ∫[0,π] 1/2 (2sin(θ))^2 dθ

Simplifying the integrand and applying the half-angle identity for sin^2(θ), we get

A = ∫[0,π] sin^2(θ) dθ

= ∫[0,π] (1 - cos^2(θ)) dθ

a) The general solution is y(x) = y_c(x) + y_p(x) = c1e^x + c2e^(4x) + 8ex.

b) The general solution is y(x) = y_c(x) + y_p(x) = c1e^(x/2)cos((√3/2)x) + c2e^(x/2)sin((√3/2)x) - (1/4)sin(3x).

For the differential equation y'' - 5y' + 4y = 8ex, the characteristic equation is r^2 - 5r + 4 = 0, which has roots r1 = 1 and r2 = 4. Thus, the complementary function is y_c(x) = c1e^x + c2e^(4x).

To find the particular solution, we guess a solution of the form y_p(x) = Ae^x. Then, y_p''(x) - 5y_p'(x) + 4y_p(x) = Ae^x - 5Ae^x + 4Ae^x = Ae^x. We need this to equal 8ex, so we set A = 8, and the particular solution is y_p(x) = 8ex.

Thus, the general solution is y(x) = y_c(x) + y_p(x) = c1e^x + c2e^(4x) + 8ex.

b) For the differential equation y'' - y' + y = 2sin(3x), the characteristic equation is r^2 - r + 1 = 0, which has roots r1,2 = (1 ± i√3)/2. Thus, the complementary function is y_c(x) = c1e^(x/2)cos((√3/2)x) + c2e^(x/2)sin((√3/2)x).

To find the particular solution, we guess a solution of the form y_p(x) = A sin(3x) + B cos(3x). Then, y_p''(x) - y_p'(x) + y_p(x) = -9A sin(3x) - 9B cos(3x) - 3A cos(3x) + 3B sin(3x) + A sin(3x) + B cos(3x) = -8A sin(3x) - 6B cos(3x). We need this to equal 2sin(3x), so we set A = -1/4 and B = 0, and the particular solution is y_p(x) = (-1/4)sin(3x).

Thus, the general solution is y(x) = y_c(x) + y_p(x) = c1e^(x/2)cos((√3/2)x) + c2e^(x/2)sin((√3/2)x) - (1/4)sin(3x).

To solve for x and y, we can use algebraic manipulation and substitution. Here are the steps:

Rearrange the first equation to solve for y in terms of x:

y = 2 - x

Substitute this expression for y into the second equation, and simplify:

x^3 + (2-x)^3 = 56

x^3 + 8 - 12x + 6x^2 - 3x^3 = 56

-2x^3 + 6x^2 - 12x + 8 = 0

Divide both sides by -2 to simplify the equation:

x^3 - 3x^2 + 6x - 4 = 0

Try to find a root of the equation using synthetic division or guess and check. One possible root is x = 2. Substituting this back into the first equation gives:

The probability that fewer than 2 students come to office hours on any given Monday is 0.70.

To find the probability that fewer than 2 students come to office hours on any given Monday, we need to calculate the sum of the probabilities of X=0 and X=1.

P(X < 2) = P(X = 0) + P(X = 1)

= 0.40 + 0.30

= 0.70

From the given probability distribution, we can see that the probability of X=0 is 0.40 and the probability of X=1 is 0.30. These represent the probabilities of no students or one student showing up for office hours, respectively.

To find the probability that fewer than 2 students come to office hours on any given Monday, we need to add these probabilities together since X can only take on integer values.

Therefore, P(X < 2) = P(X = 0) + P(X = 1) = 0.40 + 0.30 = 0.70.

This means that there is a 70% chance that either no students or one student will show up for office hours on any given Monday.

The global maximum value of f(x, y) on the closed triangular region occurs at either (4, 0) or (0, 4), both of which have a value of 16.

The global minimum value of f(x, y) occurs at the critical point (0, 0), with a value of 0

To find the Optimization of multivariable functions i.e, global extreme values of [tex]f(x, y) = x^2 - xy + y^2[/tex] on the closed triangular region in the first quadrant bounded by the lines x = 4, y = 0, and y = x,

We need to first find the critical points of the function in the interior of the region and evaluate the function at these points, and then evaluate the function at the boundary points of the region.

To find the critical points of the function in the interior of the region, we need to solve the system of partial derivatives:

[tex]df/dx = 2x - y = 0\\f/dy = -x + 2y = 0[/tex]

Solving this system of equations, we get the critical point (x, y) = (0, 0).

To check whether this point is a maximum or a minimum, we need to evaluate the second partial derivatives of f:

[tex]d^2f/dx^2 = 2\\d^2f/dy^2 = 2\\d^2f/dxdy = -1[/tex]

The determinant of the Hessian matrix is:

[tex]d^2f/dx^2 \times d^2f/dy^2 - (d^2f/dxdy)^2 = 4 - 1 = 3[/tex]

Since this determinant is positive and [tex]d^2f/dx^2 = d^2f/dy^2 = 2[/tex] are both positive, the critical point (0, 0) is a local minimum.

Next, we need to evaluate the function at the boundary points of the region. These are:

(4, 0): f(4, 0) = 16

(0, 0): f(0, 0) = 0

(0, 4): f(0, 4) = 16

(y, y) for 0 ≤ y ≤ 4: [tex]f(y, y) = 2y^2 - y^2 = y^2[/tex]

Therefore, the global maximum value of f(x, y) on the closed triangular region occurs at either (4, 0) or (0, 4), both of which have a value of 16.

The global minimum value of f(x, y) occurs at the critical point (0, 0), with a value of 0.

The strongest beam that can be cut from a round log of diameter d = 22 inches

From the figure, d² = h² + w²

=> 22² = h² + w²

=> h² = 484 - w²

plug this value in above equation, S = kw(484 - w²)

For maximum of strength, dS/dw = 0 ( critical values)

=> [tex]\frac{ d( kw(484 - w²)}{dw} = 0[/tex]

=> k( 484 - 3w²) = 0

=> 484 - 3w² = 0

=> w² = 484/3

=> w = 22/√3 = 7.33

then, h² = 484 - w²

[tex]h^2= 484 - \frac{ 484}{3} [/tex]

=> [tex] h^2= 2( \frac { 484}{3} )[/tex]

=> [tex]h = (\frac{ \sqrt2}{\sqrt3} )22[/tex]

= 17.96

Hence, required value is 17.96 inches.
