The value of b for which ∫b0cos(ex)dx is minimum is π/2e..

To find the value of b for which the definite integral ∫b0cos(ex)dx is a minimum, we can find the critical points (i.e. local extrema) of the integrand cos(ex) in the interval [0, 2].

Since cos(ex) is a periodic function with period 2π/e, it suffices to consider the interval [0, 2π/e]. In this interval, cos(ex) has its maximum value of 1 at x = 0, and its minimum value of -1 at x = π/2e and x = 3π/2e.

Since e is positive, the function cos(ex) is increasing on the interval [0, π/2e) and decreasing on the interval (π/2e, π/e].

Therefore, if b is in the interval [0, π/2e), the integral is minimized when b = 0. If b is in the interval [π/2e, π/e], the integral is minimized when b = π/2e.

Since the maximum value of b is 2, and 2 < π/e, it follows that the integral ∫b0cos(ex)dx is minimized when b = π/2e.

From the question, we have the following parameters that can be used in our computation:

Zeros: x=3, 2 +-3i

The polynomial can be repesented as

f(x) = product of (x - zeros)

using the above as a guide, we have the following:

f(x) = (x - 3)(x - (2 - 3i))(x - (2 + 3i))

This can be expressed as

f(x) = (x - 3)((x - 2)² + 9)

Now, According to the question:

A square is a two-dimensional figure with four sides. It is also known as a quadrilateral. The area of a square is defined as the total number of unit squares in the shape of a square. In other words, it is defined as the space occupied by the square.

"Information available from the question"

We have been given that the ratio of the side length of square a to the side length of square b is 4:9. The side length of square a is 12 yards.

First of all, we will find the side length of square b using proportions as:

For the orthogonal matrices, the product of two invertible matrices is also invertible.

Orthogonal matrices are matrices that have a special property: the dot product of each of their rows or columns is equal to 0.

The dot product of two vectors is equal to 0 when the vectors are orthogonal to each other, meaning they are perpendicular.

Since U and V are orthogonal matrices, each is invertible by the definition of orthogonal matrices.

The inverse of an orthogonal matrix is its transpose.

This is because the dot product of each row (or column) with itself is equal to 1, so the transpose of an orthogonal matrix is its inverse.

The product of two invertible matrices is also invertible, so UV is invertible.

The perimeter of the actual triangle is 74 and option D is the correct answer.

The scale factor is the difference in size between the original item's scale and that of the new object, which is a representation of it (bigger or smaller).

Given that the scaled dimension of the triangular face has the following dimensions:

PQ = 12

QR = PQ(1 + 25/100) = 12(125/100) = 15

PR = 2/3 (QR) = 2/3 (15) = 10

The scaling factor is 1/2 hence the actual dimensions of the triangle would be:

Original segments (1/2) = Scaled segment

Scaled (2) = Original

Using the above we have:

PQ = (12)(2) = 24

QR = (15)(2) = 30

PR =(10) (2) = 20

The perimeter of the triangle is the sum of all it sides:

Using property 8 and the midpoint rule, we have estimated the value of the integral ∫1147xdx to be approximately 14.

Property 8 of the definite integral states that if a < b and 0 < c < d, then:

∫baf(x)dx = ∫dcf(x)dx - ∫caf(x)dx

We can use this property to estimate the value of the integral ∫1147xdx. Let's choose c = 1 and d = 4, so that 0 < c < d and a < b. Then:

∫1147xdx = ∫447xdx - ∫11x dx

Next, we can use a numerical method, such as the midpoint rule or trapezoidal rule, to estimate the value of each of the integrals on the right side of the equation.

For example, using the midpoint rule with n = 4 subintervals for each integral:

∫447xdx ≈ (4 - 4/2) + (4 - 3/2) + (4 - 2/2) + (4 - 1/2) = 4 + 4 + 4 + 4 = 16

∫11x dx ≈ (1 - 1/2) + (1 - 2/2) = 1 + 1 = 2

So, our estimate of ∫1147xdx becomes:

∫1147xdx ≈ 16 - 2 = 14

Therefore, using property 8 and the midpoint rule, we have estimated the value of the integral ∫1147xdx to be approximately 14.

The sum-of-minterms form of the function f(a,b,c) = a'b + ac is (a'b + ac).

To convert a function with three variables to sum-of-minterms form, we first need to determine the truth table of the function, which lists all possible combinations of inputs and the corresponding outputs. Then, we identify the minterms (i.e., combinations of inputs that result in a 1 output) and represent each minterm as a binary number. The sum-of-minterms form of the function is then the sum of all the binary numbers representing the minterms.

For example, consider the function f(a,b,c) = a'b + ac. (The truth table for this function is attached below)

From the truth table, we can see that the minterms are (0,1,1) and (1,0,1), which can be represented as binary numbers 011 and 101, respectively. The sum-of-minterms form of the function is then:

f(a,b,c) = 011 + 101 = (a'b + ac)

So, the sum-of-minterms form of the function f(a,b,c) = a'b + ac is (a'b + ac).

Yes -20 degrees and 340 degrees are co-terminal angles

are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side. For example, the angles 30°, –330°.

co-terminal angles are found by adding or subtracting 360° to the angles.

for example the co-terminal angles of -10° = -10° + 360 = 350°
