The problem involves a subspace P2 of continuous functions over the interval (0, 2). It requires showing that the evaluation map Ev is invertible, determining coefficients for a quadrature formula, and discussing whether the formula holds for every function in C|0,2).

a) To show that the evaluation map Ev is invertible, we need to demonstrate that it is both injective (one-to-one) and surjective (onto). Injectivity means that different functions in P2 map to different points in R², and surjectivity means that every point in R² has a pre-image in P2. By examining the properties of P2 and the evaluation map, we can prove its invertibility.

b) The problem asks to find specific coefficients a₀, a₁, and a₂ that satisfy the given quadrature formula. We need to solve the equation ∫(0 to 2) [a₀ + a₁p(1) + a₂p(2)]p(c) dt = f₀p(0) + f₁p(1) + f₂p(2) for all polynomials p in P2. By substituting specific values for c and solving the resulting equations, we can determine the explicit values of a₀, a₁, and a₂.

c) The question inquires whether the quadrature formula holds for every function in C|0,2]. To justify our answer, we need to analyze the properties of the quadrature formula and determine if it provides accurate approximations for any arbitrary function in C|0,2]. This analysis involves considering the convergence properties of the formula and whether it can accurately capture the behavior of functions beyond polynomials.

The explanation provides an overview of the problem's components, including showing invertibility, finding coefficients for the quadrature formula, and discussing its applicability to functions in C|0,2]. It emphasizes the need for proofs, equations, and analysis to support the conclusions.

The value of K that will make the expressions equivalent is 10.

Considering the two expressions:

7 + (1/2)x - 3 + (3/4)x and 1 whole number (1/4)x + k - 6

we shall write the expression 7 + (1/2)x - 3 + (3/4)x in the form of the expression having k and then compare to know the value of k as follows;

(1/2)x + (3/4)x = (2x + 3x)/4

(1/2)x + (3/4)x = 5x/4

7 - 3 = 10 - 3 - 3

7 - 3 = 10 - 6

so;

7 + (1/2)x - 3 + (3/4)x = 5x/4 + 10 - 6

by comparison;

5x/4 is equal to the mixed fraction 1 whole number (1/4)x

The two lines are parallel, then the system of equations has no solutions.

A linear equation can be written as:

y = a*x +b

Where a is the slope.

If the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

Here the first line passes through (0, 3) and (3, 4), so the slope is:

a = (4 - 3)/(3 - 0) = 1/3

And the y-intercept is 3:

y = (1/3)*x + 3

The other line passes through (0, -2)and (3, -1)

a = (-1 + 2)/(3 - 0) = 1/3

And the y-intercept is -2, so this line is:

y = (1/3)*x - 2

Then the system of equations is:

y = (1/3)*x + 3

y = (1/3)*x - 2

So both equations have the same slope and different y-intercept, thus, the lines are parallel, then the system of equations has no solutions.

The given rational function y = (x² + 17) / [(x + 1)(6 + x² + 5x)] can be expressed as a sum of partial fractions as y = (-31/2)/(x + 1) + (-31/2)x - 51/(x² + 5x + 6).

What is the fraction?

A fraction is a mathematical representation of a part of a whole, where the whole is divided into equal parts. A fraction consists of two numbers, one written above the other and separated by a horizontal line, which is called the fraction bar or the vinculum.

To express the rational function y = (x² + 17) / [(x + 1)(6 + x² + 5x)] as a sum of partial fractions, we need to decompose it into simpler fractions with denominators of lower degree. The partial fraction decomposition of y will have the following form:

y = A/(x + 1) + (Bx + C)/(x² + 5x + 6)

To find the values of A, B, and C, we can use the method of equating coefficients. We'll multiply both sides of the equation by the common denominator to eliminate the denominators:

(x + 1)(x² + 5x + 6)y = A(x² + 5x + 6) + (Bx + C)(x + 1)

Expanding the equation and collecting like terms:

(x³ + 6x² + 11x + 6 + 5x² + 30x + 36)y = Ax² + 5Ax + 6A + Bx² + Bx + Cx + C

Combining like terms:

(x³ + 11x² + 41x + 42)y = (A + B)x² + (5A + B + C)x + (6A + C)

Now, we equate the coefficients of like powers of x on both sides of the equation:

For x³: 0 = A + B

For x²: 1 = A + B

For x¹: 11 = 5A + B + C

For x⁰: 42 = 6A + C

From the equation A + B = 0, we find that A = -B.

From the equation 1 = A + B, substituting A = -B, we have 1 = -B + B, which is always true.

From the equation 42 = 6A + C, we can substitute A = -B to get 42 = -6B + C.

From the equation 11 = 5A + B + C, we substitute A = -B and simplify to get 11 = -5B + B + C, which simplifies to 11 = -4B + C.

Now we can solve the system of equations:

-6B + C = 42

-4B + C = 11

Subtracting the second equation from the first, we have:

-2B = 31

B = -31/2

Substituting B = -31/2 into -4B + C = 11, we can solve for C:

-4(-31/2) + C = 11

62 + C = 11

C = 11 - 62

C = -51

Now that we have the values of A = -B, B, and C, we can write the partial fraction decomposition:

y = (-31/2)/(x + 1) + (Bx + C)/(x² + 5x + 6)

= (-31/2)/(x + 1) + (-31/2)x - 51/(x² + 5x + 6)

Therefore, the given rational function y = (x² + 17) / [(x + 1)(6 + x² + 5x)] can be expressed as a sum of partial fractions as y = (-31/2)/(x + 1) + (-31/2)x - 51/(x² + 5x + 6).

Answer:

\(-2\sqrt{3}\)

Step-by-step explanation:

\(5\sqrt{27} -17\sqrt{3} =5*3\sqrt{3} -17\sqrt{3}\)

\(=15\sqrt{3} -17\sqrt{3}\)

=\(-2\sqrt{3}\)

The solution to the equation is x = 0.

Option D is the correct answer.

We have,

The equation is:

(1 - 3x)^{1/3} - 1 = x

Let's start by isolating the radical term by adding 1 to both sides:

(1 - 3x)^(1/3) = x + 1

Next, we'll cube both sides to eliminate the radical:

[(1 - 3x)^(1/3)]^3 = (x + 1)^3

1 - 3x = (x + 1)^3

1 - 3x = x^3 + 3x^2 + 3x + 1

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

Now we have a cubic equation, which we can solve by factoring out an x:

x(x^2 + 3x + 6) = 0

The quadratic factor doesn't have any real roots (since its discriminant is negative),

So the only solution is x = 0.

i.e

(1 - 3x)^(1/3) - 1 = 1^(1/3) - 1 = 0.

Thus,

The solution to the equation is x = 0.

Answer:

Mr. Crow dimension of the lawn = 85 × 40

Area of the lawn = 3250 square feet

Step-by-step explanation:

Let x represents the width of the rectangle,

Then According to the question,

The length of the rectangle = 2 x + 5

Also it is given that the perimeter of the rectangle = 250 feet.

But we know that the perimeter of the rectangle = 2 × ( length + width)

Thus, the perimeter of the rectangle = 2( 2x+5+x) = 2(3x+5) = 6x+10

If x = 30,  the perimeter of the rectangle = 6 × 30 + 10 = 190 < 250

Thus, x ≠ 10.

If x = 50,  the perimeter of the rectangle = 6 × 50 + 10 = 310 > 250

Thus, x ≠ 50

If x  = 40, the  the perimeter of the rectangle = 6 × 40 + 10 = 250 = 250

Thus, x = 40

Therefore, the width of the rectangle, x  = 40 feet.

And, the length of the rectangle, 2 x + 5 = 2 × 40 + 5 = 85 feet.

1) The dimension of the rectangle = 85 × 40

2)The area of the rectangle = length × width = 85 × 40  = 3250 square feet.Let x represents the width of the rectangle,

Then According to the question,

The length of the rectangle = 2 x + 5

Also it is given that the perimeter of the rectangle = 250 feet.

But we know that the perimeter of the rectangle = 2 × ( length + width)

Thus, the perimeter of the rectangle = 2( 2x+5+x) = 2(3x+5) = 6x+10

If x = 30,  the perimeter of the rectangle = 6 × 30 + 10 = 190 < 250

Thus, x ≠ 10.

If x = 50,  the perimeter of the rectangle = 6 × 50 + 10 = 310 > 250

Thus, x ≠ 50

If x  = 40, the  the perimeter of the rectangle = 6 × 40 + 10 = 250 = 250

Thus, x = 40

Therefore, the width of the rectangle, x  = 40 feet.

And, the length of the rectangle, 2 x + 5 = 2 × 40 + 5 = 85 feet.

1) The dimension of the rectangle = 85 × 40

2)The area of the rectangle = length × width = 85 × 40  = 3250 square feet.

Answer:

# of quarters: 12 # of dimes: 7

# of large boxes:  14 # of small boxes: 12

Step-by-step explanation:

Problem 1: Dimes and Quarters

Let q represent the number of quarters
Let d represent the number of dimes

We have as a first equation
q + d = 19  (1)

Each quarter is worth $0.25 so q quarters worth = 0.25q

Each dime is worth $0.10 so d dimes worth = 0.10d = 0.1d

Total value of q quarters and d dimes
0.25q + 0.1d = 3.70 (2)

We have two equations in 2 variables which can be solved as follows

Verify:
12 x 0.25 + 7 x 0.10 = 3.70

Problem 2: Apricots

Solution strategy is the same as Problem 1 so I am skipping lengthy explanations

Let L be the number of large boxes, S be the number of small boxes

We have
L + S = 26   (1)

Total cost of boxes

7L + 4S = 146  (2)

Multiply equation (1) by 4 :
4L + 4S = 4 x 26 = 104  (3)

Subtract (2) from (3):
7L + 4S - (4L + 4S) = 146 - 104
3L = 42
L = 42/3 = 14

Substitute in (1)
14 + S = 26
S = 26-14
S = 12

So there are 14 large and 12 small boxes
