Answer: You basically have to 2xlw+2wh+2lh which means

2 multiplied by the length and width + 2 x the width and the height+ 2 x the length and height

Example:

l= 2

w=5

h=4

2x2x5+2x5x4+2x2x4

I hope this helps

How are reflections represented as a function? what is the relationship between a reflection and a rigid motion?

hjlf

Reflections are a type of transformation that move an entire curve such that its mirror image lies on the other side of the x or y axis.

A vertical reflection is given by the equation y=−f(x) and results in the curve being "reflected" across the x-axis. A horizontal reflection is given by the equation y=f(−x) and results in the curve being "reflected" across the y-axis.

Reflection is one of the four basic rigid motions.

Four basic rigid motions:

1.Reflection

2.Glide Reflection

3.Rotation

4.Translation

The graph shows the speed of a cart over a period of several minutes. At approximately what time did the speed of the cart begin

Aleksandr [31]

The speed of the cart begin to decrease at approximately: 3.5 minutes.

<h3>What is a Time-Speed Graph?</h3>

A typical time-speed graph shows the time on the x-axis and the speed on the y-axis. When the slope is rising, it means the speed is increasing. When the slope is horizontal, it means the speed is constant. When the slope falls or decline, it means speed is decreasing.

We are given a time-speed graph that shows the speed of a cart over a period of several minutes. Time in minutes is on the x-axis (horizontal axis) while speed in miles per hour is on the y-axis (vertical axis).

From the graph given, the speed of the cart started increasing up to about 3 minutes, since the line slopes upwards. Then, between 3 and 4 minutes, we have a horizontal line which starts to decline at approximately 3.5 minutes.

Therefore, we can conclude that the speed of the cart begin to decrease at approximately: 3.5 minutes.

An object is dropped from a small plane. As the object falls, its distance, d, above the ground after t seconds, is given by the

DedPeter [7]

The inequality can be used to find the interval of time taken by the object to reach the height greater than 300 feet above the ground is:

$d = -16t^2 + 1000$

Solution:

The object falls, its distance, d, above the ground after t seconds, is given by the formula:

$d = -16t^2 + 1000$

To find the time interval in which the object is at a height greater than 300 ft

Frame a inequality,

$-16t^2 + 1000 > 300$

Solve the inequality

Subtract 1000 from both sides

$-16t^2 + 1000 - 1000 > 300 - 1000\\\\-16t^2 > -700$

$16t^2 < 700\\\\Divide\ both\ sides\ by\ 16\\\\t^2 < \frac{700}{16}\\\\Take\ square\ root\ on\ both\ sides\\\\t < \sqrt{\frac{700}{16}}\\\\t < \pm 6.61$

Time cannot be negative

Therefore,

t < 6.61

And the inequality used is: $-16t^2 + 1000>300$
