A cyclist is travelling at an average speed of 24km/h.

netineya [11]

Answer:

The answer is: 1. 5 minutes and 2. 133.3 meters

Step-by-step explanation:

To find how long it takes the cyclist to travel 2km at 24km / hour, set up the equation and cross multiply:

2 / 24 = x / 1

24x = 2

x = 2/24 = 1/12 of an hour or 60 / 12 = 5 Minutes.

To find how far he travels in 20 seconds:

Multiply 24 km by 1000 to get meters per hour. Divide by 3600 to get meters per second:

24000 / 3600 = 6.6 meters per second.

Multiply by 20 seconds to get the distance traveled in 20 seconds:

6.6 * 20 = 133.3

(TIME SENSITIVE PLEASE HELP) Use matrices to determine the coordinates of the vertices of the reflected figure. Then graph the p

Len [333]

The matrix R represents the reflection matrix for the provided vertices, and graph A represents the pre-image and the image on the same coordinate grid.

<h3>What is the matrix?</h3>

It is defined as the group of numerical data, functions, and complex numbers in a specific way such that the representation array looks like a square, rectangle shape.

We have vertices shown in the picture.

Form a matrix using the vertices:

$= \left[\begin{array}{ccc}-3&5&6\\7&3&-5\\\end{array}\right]$

To reflect over the x-axis, multiply by the reflection matrix:

$= \left[\begin{array}{ccc}1&0\\0&-1\\\end{array}\right]\left[\begin{array}{ccc}-3&5&6\\7&3&-5\\\end{array}\right]$

$\rm R= \left[\begin{array}{ccc}-3&5&6\\-7&-3&5\\\end{array}\right]$

The above matrix represent the reflection matrix.

Thus, the matrices R represents the reflection matrix for the provided vertices, and graph A represents the pre-image and the image on the same coordinate grid.
