To express the column matrix b as a linear combination of the columns of A, we need to find scalars x, y, and z such that x[\begin{array}{c} 1\\2\end{array}\right] + y[\begin{array}{c} 1\\-3\end{array}\right] + z[\begin{array}{c} -1\\3\end{array}\right] = [\begin{array}{c} -5\\5\end{array}\right].

Writing this out as a system of equations, we get:

x + y - z = -5
2x - 3y + 3z = 5

We can solve for x, y, and z by putting the coefficients of the variables into an augmented matrix and row reducing:

[\begin{array}{ccc|c} 1&1&-1&-5\\2&-3&3&5\end{array}\right]

R2 - 2R1 --> R2

[\begin{array}{ccc|c} 1&1&-1&-5\\0&-5&5&15\end{array}\right]

-1/5R2 --> R2

[\begin{array}{ccc|c} 1&1&-1&-5\\0&1&-1&-3\end{array}\right]

R1 - R2 --> R1

[\begin{array}{ccc|c} 1&0&-2&-2\\0&1&-1&-3\end{array}\right]

So we have x = -2, y = -3, and z = -2. Therefore, we can write b as a linear combination of the columns of A as:

[\begin{array}{c} -5\\5\end{array}\right] = -2[\begin{array}{c} 1\\2\end{array}\right] - 3[\begin{array}{c} 1\\-3\end{array}\right] - 2[\begin{array}{c} -1\\3\end{array}\right]

Answer:

25y² - 30y + 9

Step-by-step explanation:

Hello!

Solve by expanding:

Remember, exponents are not distributive, meaning (5y - 3)² is not 25y² + 9.

The volume (V) of the solid obtained by rotating the region bounded by the curves y = 5x^3, y = 5x, x ≥ 0 about the x-axis is V = ∫[0,1] 2πx((5x) - (5x^3))dx.

To find the volume of the solid, we can use the method of cylindrical shells. We will integrate the volume of each shell as it rotates around the x-axis.

First, let's sketch the region bounded by the curves. The curve y = 5x^3 intersects with the line y = 5x at two points: (0, 0) and (1, 5). The region between these curves is bounded by the x-axis and the curves. It looks like a "bowl" shape, opening upwards, with the bottom touching the x-axis.

Next, let's visualize a typical cylindrical shell. Imagine taking a thin strip of thickness Δx at a distance x from the x-axis. When this strip rotates around the x-axis, it forms a cylindrical shell. The height of this shell is the difference between the two curves: (5x) - (5x^3). The circumference of the shell is 2πx since it is the distance around the axis of rotation. The thickness of the shell is Δx.

The volume of the shell is given by V_shell = 2πx((5x) - (5x^3))Δx. To find the total volume, we need to sum up all these shells by integrating with respect to x.

Integrating V_shell from x = 0 to x = 1, we get V = ∫[0,1] 2πx((5x) - (5x^3))dx.

Evaluating this integral will give us the volume of the solid obtained by rotating the region about the x-axis.

The equation for the volume of a cylindrical shell is:

V = πr² * h * w, where r is the radius of the semicircle base, h is the height of the shell, and w is the width of the shell.

The volume of the solid can be found using the method of cylindrical shells. The volume of each cylindrical shell is equal to the product of the area of the base (a semicircle), the height of the shell, and the width of the shell (which is equal to the difference in the x-coordinates of the two vertices that define the height).

To find the total volume, we would sum up the volumes of all the cylindrical shells, from the top to the bottom of the solid.

The equation for the volume of a cylindrical shell is:

V = πr² * h * w, where r is the radius of the semicircle base, h is the height of the shell, and w is the width of the shell.

The height of the shell is given by the difference in the y-coordinates of the two points that define the height, and the width of the shell is given by the difference in the x-coordinates of these two points.

To find the total volume, we would integrate the volume of the cylindrical shell over the height of the solid. The limits of integration would be the y-coordinates of the bottom and top of the solid.

Answer:

She made $1230 more on printed shirts than plain shirts in 25 weeks.

Step-by-step explanation:

Hi,

Okay, I have to admit, this is pretty complicated. But, it's not impossible :) First things first, we know that the equation in the table is the number of shirts sold after W number of weeks. We know that we need to, first, find the total number of shirts sold in 25 weeks.

The equation for the plain shirts is 5w -4. Let's start with that.

Plugin 25 for w to find the total number of plain shirts sold after 25 weeks.

5w - 4

5(25) - 4

= 121

She sold 121 plain shirts after 25 weeks. But we're not done yet, we still have to see how much money she made after selling 121 plain shirts. To do this, we have to multiply the total number of plains shirts sold by 15. (we know that each plain short costs $15, that's why we're multiplying it by 121)

When you do this...

121 x 15

You get...

$1815

She got $1815 after 25 weeks just for selling plain shirts.

Now, let's find the total cost of printed shirts after 25 weeks.

The equation for the printed shirts if 8w + 3.

8w + 3

8(25) + 3

= 203

She sold 203 printed shirts in 25 weeks. Let's find the cost. Each printed shirt costs $15 so we need to multiply 203 by 15.

203 x 15

You get...

$3045

She made $3045 by selling printed shirts in 25 weeks.

Now, we have to subtract $3045 by $1815 to find how much more she made. You get...

3045 - 1815

= $1230

She made $1230 more on printed shirts than plain shirts in 25 weeks.

I really hope this helps :)

Step-by-step explanation:

The value of the contour surface passing through the point (1, 0, 2) is ψ(1, 0, 2) = 1^2 + 2e^0 = 1 + 2 = 3.

To find the points on the curve where the tangent is horizontal, we need to determine the values of t that satisfy the condition for a horizontal tangent, which is when the derivative of y with respect to t is equal to 0.

Given the parametric equations:

x = 2t^3 + 3t^2 - 12t

y = 2t^3 + 3t^2 + 1

Taking the derivative of y with respect to t:

dy/dt = 6t^2 + 6t

Setting dy/dt equal to 0 and solving for t:

6t^2 + 6t = 0

t(6t + 6) = 0

From this equation, we have two possible solutions:

t = 0

6t + 6 = 0, which gives t = -1.

Therefore, the points on the curve where the tangent is horizontal are (0, y(0)) and (-1, y(-1)). To find the corresponding y-values, substitute the values of t into the equation for y:

For t = 0:

y(0) = 2(0)^3 + 3(0)^2 + 1 = 1

For t = -1:

y(-1) = 2(-1)^3 + 3(-1)^2 + 1 = -2 + 3 + 1 = 2

Hence, the points on the curve where the tangent is horizontal are (0, 1) and (-1, 2).

To find the points on the curve where the tangent is vertical, we need to determine the values of t that satisfy the condition for a vertical tangent, which is when the derivative of x with respect to t is equal to 0.

Taking the derivative of x with respect to t:

dx/dt = 6t^2 + 6t - 12

Setting dx/dt equal to 0 and solving for t:

6t^2 + 6t - 12 = 0

t^2 + t - 2 = 0

(t + 2)(t - 1) = 0

From this equation, we have two possible solutions:

t + 2 = 0, which gives t = -2

t - 1 = 0, which gives t = 1.

Therefore, the points on the curve where the tangent is vertical are (x(-2), y(-2)) and (x(1), y(1)). To find the corresponding x-values and y-values, substitute the values of t into the equations for x and y:

For t = -2:

x(-2) = 2(-2)^3 + 3(-2)^2 - 12(-2) = -16 + 12 + 24 = 20

y(-2) = 2(-2)^3 + 3(-2)^2 + 1 = -16 + 12 + 1 = -3

For t = 1:

x(1) = 2(1)^3 + 3(1)^2 - 12(1) = 2 + 3 - 12 = -7

y(1) = 2(1)^3 + 3(1)^2 + 1 = 2 + 3 + 1 = 6

Hence, the points on the curve where the tangent is vertical are (20, -3) and (-7, 6).

To evaluate the indefinite integral ∫x³√√(4+x²) dx, we can make a substitution to simplify the expression. The final result is (1/3)u³ - 4u + C, where C is the constant of integration.

To evaluate the indefinite integral ∫x³√√(4+x²) dx, we can make a substitution to simplify the expression. Let u = √(4+x²), then du = (x/√(4+x²)) dx. Rearranging this equation, we have dx = (du/u)√(4+x²).

Substituting these values into the integral, we get:

∫x³√√(4+x²) dx = ∫x³ (du/u)√(4+x²)

Simplifying further, we have:

= ∫(x²/u)√(4+x²) du

Expanding the numerator, we get:

= ∫(u² - 4) du

Now we can integrate each term separately:

∫u² du - ∫4 du

Integrating u² with respect to u gives us (1/3)u³, and integrating the constant -4 with respect to u gives us -4u.

Therefore, the integral becomes:

= (1/3)u³ - 4u + C

Finally, substituting back u = √(4+x²), we have:

= (1/3)(√(4+x²))³ - 4√(4+x²) + C

Hence, the indefinite integral of x³√√(4+x²) dx is (1/3)(√(4+x²))³ - 4√(4+x²) + C, where C is the constant of integration.

C) Cοmparing the twο areas, we can see that the pizza frοm Lοs Angeles has a larger area than the pizza frοm Lοndοn.

Part A:

Tο find the area οf the pizza frοm Lοs Angeles, we need tο use the fοrmula fοr the area οf a circle:

A = πr²

where r is the radius οf the circle, which is half the diameter.

d = 14 inches

r = d/2 = 7 inches

Substituting the value οf r intο the fοrmula, we get:

A = π(7)²

A = 49π

Using a calculatοr οr apprοximating π tο 3.14, we get:

A ≈ 153.94 square inches

Part B:

Tο find the area οf the pizza frοm Lοndοn, we use the same fοrmula fοr the area οf a circle, but we need tο cοnvert the diameter frοm centimeters tο inches first.

d = 25.4 centimeters = 25.4/2.54 inches

d ≈ 10 inches

r = d/2 ≈ 5 inches

A = π(5)²

A = 25π

Using a calculatοr οr apprοximating π tο 3.14, we get:

A ≈ 78.5 square inches

Part C:

Tο cοmpare the areas οf the twο pizzas, we need tο cοnvert the area οf the pizza frοm Lοs Angeles tο square centimeters, since the area οf the pizza frοm Lοndοn is given in square centimeters.

1 inch = 2.54 centimeters

1 square inch = (2.54)² square centimeters

1 square inch ≈ 6.45 square centimeters

Area οf pizza frοm Lοs Angeles ≈ 153.94 square inches

Area οf pizza frοm Lοs Angeles in square centimeters ≈ 153.94 x 6.45 ≈ 992.52 square centimeters

Area οf pizza frοm Lοndοn ≈ 78.5 square inches

The matrix must have pivot columns. Otherwise, the equation Ax = 0 would have a free variable, in which case the columns of A would not span R5. Therefore, the correct answer is C.

A pivot column is a column of the matrix that has a non-zero entry in the pivot position and all entries below the pivot are zero. In row echelon form, every row below a pivot column has a zero in the corresponding position. The pivot columns correspond to the linearly independent columns of the original matrix and the number of pivot columns determines the rank of the matrix.

The rank of a matrix is defined as the number of linearly independent columns or rows in the matrix. If the columns of a matrix span Rn, then the rank of the matrix must be equal to n. This means that the matrix must have n linearly independent columns. To ensure that the columns of A span R5, A must have at least 5 pivot columns. If A had fewer pivot columns, then the equation Ax = 0 would have a non-trivial solution, meaning that the columns of A would not be linearly independent and would not span R5.
