Points vectors Apply the Determinant Linear Independence Test to decide whether the [5] 4 0 4 3 2 2 2 V1: 0 3 are linearly independent in R4. a) Evaluate the corresponding determinant. (b) Make your conclusion.

Answers

The determinant of the matrix formed by the given vectors is -4, indicating that the vectors are linearly independent in R⁴.

To evaluate the determinant of the given set of vectors V₁ = [5, 4, 0, 4] and V₂ = [3, 2, 2, 2] using the expanded matrix form, we can write:

| 5 3 |

| 4 2 |

| 0 2 |

| 4 2 |

Expanding the determinant along the first row, we can calculate it as follows:

det = 5 * det(| 2 2 |) - 3 * det(| 4 2 |)

| 4 2 | | 0 2 |

We can evaluate each determinant separately:

det(| 2 2 |) = (2 * 2) - (2 * 0) = 4 - 0 = 4

det(| 4 2 |) = (4 * 2) - (2 * 0) = 8 - 0 = 8

Substituting these determinants back into the expanded expression:

det = 5 * 4 - 3 * 8

= 20 - 24

= -4

Therefore, the determinant of the given matrix is -4.

Based on the determinant being nonzero (-4 ≠ 0), we can conclude that the vectors V₁ = [5, 4, 0, 4] and V₂ = [3, 2, 2, 2] are linearly independent in R⁴.

After t =

Answers

Answer:

After t =  1.67 seconds, the rocket will have reached a height of 250 centimeters.

Step-by-step explanation:

Given

[tex]h = -90t^2 + 300t[/tex] --- correct expression

Required: When does height = 250 cm

To do this, we have:

[tex]h = 250[/tex]

This gives:

[tex]250 = -90t^2 + 300t[/tex]

Rewrite as:

[tex]90t^2 - 300t + 250 = 0[/tex]

Divide through by 10

[tex]9t^2 - 30t + 25 = 0[/tex]

Expand

[tex]9t^2 - 15t - 15t + 25 = 0[/tex]

Factorize:

[tex]3t(3t - 5) -5(3t - 5) = 0[/tex]

[tex](3t - 5)(3t - 5) = 0[/tex]

We can easily calculate the slope using the slope formula

now we plug in the values into the formula

(remember y values on top and x values down below)

Some chocolate bars are scored (split apart) into equal parts to make them easy to break apart and share. Simon wants to share five chocolate bars equally among four people. The chocolate bars are scored in four equal parts. How should Simon share all the chocolate bars so four people each have an equal share? Show all your mathematical thinking.

Answers

Answer:

If every bar is scored into 4 parts, then Simon has 5*4 parts in total = 20 parts.

To split them between 4 people, each person gets 20/4 parts - 5 parts in total. The way to realize this the easiest would be to give each person a single bar, and then split the last bar into 4 parts and give each person one of them.

All
bags of marbles from Esteban's Marble Company have 7 green marbles

purple marbles are in the bag?

Answers

There are 32 purple marbles in the bag.

All bags of marbles from Esteban's Marble Company have 7 green marbles for every 4 purple marbles.

To find out the number of purple marbles, let's represent the ratio of the number of green marbles to purple marbles as 7:4.

Since the ratio of green marbles to purple marbles is constant for all bags of marbles, we can create the following equation:

x/4 = 56/7 where x is the number of purple marbles in the bag.

To solve for x, we can cross-multiply:7x = 224

Dividing by 7 on both sides,

x = 32

Hence, the number of purple marbles in the bag is 32.

Lets be a given function. A graphical interpretation of the 3-point central difference formula for approximating f'(x) is the slope of the line joining the points of absuissas Xoth h with h > 0.
T/F

Answers

True. The graphical interpretation involves calculating the slope of the line connecting two points on the graph of the function, with the distance between the points denoted as h, where h is greater than zero.

The 3-point central difference formula is a numerical approximation technique used to estimate the derivative of a function at a specific point. In this formula, the slope of the line joining two points on the graph of the function is used to approximate the derivative.

To apply the 3-point central difference formula, three points on the graph are considered: (x-h, f(x-h)), (x, f(x)), and (x+h, f(x+h)), where h is a positive value. These three points create two lines: one connecting (x-h, f(x-h)) and (x, f(x)), and the other connecting (x, f(x)) and (x+h, f(x+h)).

The slope of the line joining the points (x-h, f(x-h)) and (x+h, f(x+h)) is then calculated, which represents the approximation of the derivative at x using the 3-point central difference formula. The distance between the two x-coordinates, h, is taken to be greater than zero to ensure that the points are not too close together, allowing for a more accurate estimation of the derivative.

Therefore, the statement is true, as the graphical interpretation of the 3-point central difference formula involves calculating the slope of the line joining the points with a positive value of h.

To get the mean, you have to add all the numbers together, and then divide them by how many numbers there are. Here, i'll show you.

There are 6 numbers, including [tex]Y[/tex], which we need to find out.

The Equation:  [tex]\frac{4+6+9+Y+16+19}{6} = 13[/tex]

We can simplify this equation into, [tex]\frac{54 + Y}{6} = 13[/tex]

To find [tex]Y\\[/tex], we can do the inverse, and multiply [tex]13[/tex] by [tex]6[/tex].

(The 6 on the left side of the equation is then cancelled out)

[tex]\frac{54+Y}{6} = 13[/tex]  becomes  [tex]54 +Y =13[/tex] × [tex]6\\[/tex][tex]13[/tex] × [tex]6 = 78[/tex] so then [tex]54 + Y = 78[/tex]

Write a rule for the nth term of the geometric sequence:

Answers

Answer:

tn = -1350 + 468n  

Step-by-step explanation:

First, we need to find the difference.

1458 - 54 / 6 - 3

= 468

Now we need to find the first term.

t3 = t1 + (n - 1) (d)

54 = t1 + (3 - 1)(468)

54 = t1 + (2)(468)

54 = t1 + 936

-882 = t1

The rule is:

tn = -882 + (n-1) (468)

tn = -882 + 468n - 468

tn = -1350 + 468n

What is a function?

function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = (x + 1)² + 2

f(x) = x² + 2x + 1 + 2

f(x) = x² + 2x + 3

Now it is in the form of ax² + bx + c

a = 1

b = 2

c = 3

The coordinate of the Vertex of the function is (-b/2a, f(x)) = (x, y)

-b/2a = -2/2 = -1

f(x) = (-1)² + 2 x (-1) + 3 = 1 - 2 + 3 = 4 - 2 = 2

Vertex = (-1, 2)

The axis of symmetry is the x-coordinate of the vertex.

= -1.

Thus,

Vertex is (-1, 2).

The axis of symmetry is -1.
