The experiment provides students with the opportunity to comprehend solids and volumes visually, physically, and mathematically.
This activity aims at enabling the student to gain a better understanding of solids and volumes by constructing a three-dimensional solid out of some cardboard, calculating its volume, and answering a few questions about it. The physical model built gives students the ability to feel the object in question and examine it from all sides to come to an understanding of the object's volume. Students need their senses to understand what they're doing as they enter the 3D world, as "feeling" here means real, physical, and sense-of-touch feeling.
Students will construct a solid with six squares of the same size. This solid can be described as a rectangular cube or a hexahedron. The square faces of the cube are oriented parallel to the ground, giving it a rectangular appearance. The cross-sections used were square-shaped. The solid made from cardboard with six square faces that are congruent to one another can be compared to a rectangular box. The volume of a cube is V=a^3, where a is the length of one side of the cube, so the volume of the cube can be calculated by finding the product of the length, width, and height of the box.
The cardboard cube's volume can be calculated by multiplying the length, width, and height of the box, which should be equal since all faces are squares of the same size.Would you have computed the same volume if you'd arranged your cross-sections differently? Is that what you'd expect to happen? The volume of the object would remain constant no matter how the cross-sections were arranged. As long as the box's length, width, and height remain the same, the volume of the object will remain constant.
What did you learn about volume from this experiment?This activity provides an opportunity for students to learn and understand the concept of volume. Students can learn about the relationship between an object's volume and its shape through constructing and calculating the volume of the cardboard solid. They will learn that the volume of a 3D shape refers to the space inside of the object.
They will learn to compute volume as the product of length, width, and height, and that the volume of an object remains constant no matter how the cross-sections are arranged. The experiment provides students with the opportunity to comprehend solids and volumes visually, physically, and mathematically.

Answer:
f(-4) = -20
f(1) = 5
f(2) = 10
f(3) = 15
f(6) = 30
Step-by-step explanation:
Since the equation is f(x) = 5x, you will have to substitute the x-values into the equation to find out what f(x) equals for each one.
For example, for x = -4, f(-4) would equal -20 since 5 * -4 = -20.
The rest would be:
f(1) = 5 * 1 = 5
f(2) = 5 * 2 = 10

Answer:
Can't be answered, as written.
Step-by-step explanation:
Please check the equations. As written, they are the same:
y=2x-4 and 6x-3y=12
The second, 6x-3y=12, can be rewritten:
-3y = -6x + 12
y = 2x - 4 is the same as the first equation.
========
I'll do an example based on a different first equation. Let's try:
y = 4x-4 and 6x-3y=12
There are two equations and 2 unknowns. We can solve this in either of two ways: Mathematically and Graphically. Let's try both.
Mathematically.
Pick either equation and isolate one of the variables (x or y)
I'll chose the first, since the variable y is already isolated. (the efficient approach)
y = 4x-4
Take the second equation and use the definition of y provided by the first equation in place of y is the second:
6x-3y = 12
6x-3(4x-4) = 12 [Substituted the value of y given in the first equation]
6x - 12x + 12 = 12
-6x=0
x= 0
Use x = 0 in either equation to find y:
y = 4x-4
y=4*(0)-4
y = -4
The solution (where the lines intersect) is (0,-4)
We can also solve this graphically.
Plot the two lines and look for their intersection. The attached graph shows that to be (0,-4).

How do you find the mirror image of a curve with respect to a line?
Finding the mirror image of a curve with respect to a line is a relatively straightforward task.
What is mirror image?Mirror image is an exact reflection of an object or an image as seen in a mirror. It is an image that is flipped from left to right, with the left side of the image becoming the right side and vice versa. This type of reflection is also known as a lateral inversion. In art and photography, mirror images are often used for aesthetic purposes and to create symmetry.
Firstly, you need to determine the line of reflection. This can be identified by using the angle bisector of the two lines that form the curve. Once you have identified the line of reflection, draw a line perpendicular to it. This is the axis of symmetry.
Next, draw a line parallel to the axis of symmetry. This line will serve as the mirror line. Now, you can start plotting the points of the curve with respect to the mirror line. To do this, take the midpoint of the curve and reflect it across the mirror line. Then, take the points on either side of the midpoint, and reflect them across the mirror line as well. Repeat this process for all the points on the curve.
Finally, connect the reflected points to form the mirror image of the curve. This will give you the same curve, just flipped across the mirror line. It is important to note that the mirror image of the curve will be a mirror reflection of its original shape, but its orientation may be different.

cost of one ft² of grass sod and the cost of one bunch of ornamental grass.
Therefore , the solution to the given problem of equation comes out to be $12 for a geranium and $11 for a square foot of grass.
Explain the equation.When connecting two statements, a mathematical equation uses its equal sign (=) to denote equivalence. An equation in algebra is a claim that establishes the comparability of two equations. For instance, the formula 5x + 5 = 14 establishes a link between the two integers. The spaces seen between phrases with either front of a letter are used to form a mathematical connection. The lone variable so the only outcome are frequently the symbol. For instance, 8x - 4 = 2.
Here,
To start, you should underline and group pertinent information. Sort the products according to the individual who purchased them. We can give each of the two purchased things a constant or letter as there are only two of them:
Kim
5 feet by 2 feet (X for short) of grass
10 geraniums, designated as "Y" geraniums; total cost: $175
Matt
9 ft 2 of grass (let's call it grass X).
Four geraniums, designated as Y.
$147 in total
Now that the data has been split, you may create two equations: one for Matt and one for Kim.
Kim
5x + 10y = $175
Matt 9x plus 4y = $147
Observe how the numbers remained constant, but I eliminated the units and substituted X or Y depends on just what we assigned. We can start solving now.
I'll take the x out of Kim's equation. the following steps:
1) 5x + 10y = $175 Rewriting the equation
2) If you'd want to perform y first, 5x = $175 - 10y (again, you can still do y first as we're trying to isolate x). That's exactly how I did it.)
3) (5x)÷5 = ($175 - 10y)÷5 (divide both aspects of the equation by 5)
4) 5x + 10y = $175
=>5x + 10($12) = $175
5x + 10($12) = $175
Add the value of y = $12 to Kim's equation to get 5x + $120 = $175.
5) 5x = $175 - $120
=> 5x = $55
=> x = $11
x = $11
Therefore , the solution to the given problem of equation comes out to be $12 for a geranium and $11 for a square foot of grass.

Which of the following graphs does NOT describe y as a function of x?
Answer:
The x value of a point where a vertical line intersects a function represents the input for that output y value. If we can draw any horizontal line that intersects a graph more than once, then the graph does not represent a function because that y value has more than one input.

The sum of the length of any two sides of a triangle is greater than the length of the third side
3 + 4 = 7
so your answer is NO
Question 2-1
A company is offering a bank account. The value, in dollars, of the account is represented by the function A(r) = 50,000(1.02), where t represents the number of years since
the account was first opened. Determine the average rate of change of the account value from t=0 to t=5. Express your answer to the nearest cent.
It represents the average amount of change in the function per unit throughout that time period.
What is the rate of change of the average?Divide the change in y-values by the change in x-values to calculate the average rate of change. When analyzing changes in measurable parameters like average speed or average velocity, finding the average rate of change is quite helpful.
The formula R = D/T, or rate of change equals the distance traveled divided by the time required to do so, can be used to approach rate-of-change problems in general.
It represents the average amount of change in the function per unit throughout that time period. It is generated from the slope of the straight line joining the interval's ends on the graph of the function.

2 1/10 + 1 2/3
= 3 13/30
Answer:
b)
[tex]2 \times \frac{19}{30} [/tex]
c)
[tex]3 \times \frac{23}{30} [/tex]
Step-by-step explanation:
b)
x - 5/6 = 1 × 4/5
x - 5/6 = 9/5
x = 5/6 + 9/5
x = (25+54)/30
x = 79/30 (or 2×19/30)
c)
x - 2 × 1/10 = 1 × 2/3
x - 21/10 = 5/3
x = 21/10 + 5/3
x = (63+50)/30
x = 113/30 (or 3×23/30)

How to model a linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the change in y when x is increased by one.b is the intercept, representing the value of y when x = 0.For the graph that has a slope of -2/3 and a y-intercept of 2, we have that:
The intercept of 2 means that the function passes through (0,2).The intercept of -2/3 means that the function passes through (3,0), as when x increases by 3, y decays by 2.The y-intercept and the slope of the equation y = 0.5x - 1 is given as follows:
-1, meaning that the function passes through the point (0,-1).
When x = -2, the value of the function is given as follows:
y = 0.5(-2) - 1
y = -1 - 1
y = -2.
Hence the other point is (-2,-2).
For the relation in item 3, we have that when x increases by 3, y decays by 6, hence the slope m is given as follows:
m = -6/3
m = -2.
Hence:
y = -2x + b.
When x = 2, y = 54, hence the intercept b is given as follows:
54 = -2(2) + b
b = 58.
Hence the function is:
y = -2x + 58.
The points are:
(0,58): y-intercept of 58.(1,56): when x increases by one, y decays by 2.More can be learned about linear functions at https://brainly.com/question/24808124
