The difference between simple and compound interest in a savings account is that ______________.
Answer:
The difference is that the simple interest gives you interest only on the deposited amount in the account while the compound interest is calculated over the deposited amount and the previous interest amount added to the deposited amount.
Step-by-step explanation:
The difference between simple and compound interest is that simple interest is calculated only on the principal amount, while compound interest is earned on past interest.
Explanation:The difference between simple and compound interest in a savings account is that simple interest is an interest rate calculation only on the principal amount, while compound interest is interest that is earned on past interest. This means that with compound interest, the total amount of savings will grow dramatically over time. To illustrate this, consider the example of putting $1,000 in a savings account with 10% interest. With simple interest, after one year, you will have $1,100. But with compound interest, if you leave the $1,100 in the account and continue to earn 10% interest, you will have $1,210 at the end of year two.

Answer:
A. y = 8.34x + 10
Step-by-step explanation:
The first choice is appropriate to the situation where y=10 when x=0 and where y increases by 83.4 when x increases by 10.
___
The equation of selection D is the same and is also appropriate, but the graph does not match the equation. The equations of the other choices are incorrect, as are the graphs.
The linear equation which represents the data is : y = 8.34x + c. Hence, correct option is A.

subtracting the second equation from the first equation we get,
7y = 12
y=12/7
This is the correct option
Answer:
A ) subtract the second equation from the first equation
Step-by-step explanation:
Let's consider the following system of equations.
2x + 3y = 7
2x = 4y - 5
If we subtract the second equation from the first equation, we get:
2x + 3y - 2x = 7 - (4y - 5)
3y = 7 - 4y + 5
7y = 12
y = 12/7
Then, we can use any of the original equations and solve for x.
2x = 4y - 5
2x = 4(12/7) - 5
x = 13/14

write the equation 2x-3y=6in slope -intercept form
Answer:
y = 2/3 x -2
Step-by-step explanation:
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
We need to solve for y
2x-3y = 6
Subtract 2x from each side
2x-2x-3y=-2x+6
-3y = -2x+6
Divide by -3
-3y/-3 = -2/-3x+6 /-3
y = 2/3 x -2
The slope is 2/3 and the y intercept is -2

the image of point A after a dilation of 3 is (6,15). What was the orgianal location of Point A?
Answer:
(2, 5)
Step-by-step explanation:
Dilating 3, means that the values were multiplied by 3. To find their original location, divide the x and y values of the new point by 3...
(6/3, 15/3) = (2, 5)
In a dilation with a factor of 3, to find the original coordinates from the dilated point (6,15), we divide each coordinate by the dilation factor. The original point A was at (2,5).
In mathematics, dilation is a geometric transformation that resizes a figure, maintaining its shape but changing its size. It involves multiplying the coordinates of each point in the figure by a constant scale factor. If the scale factor is greater than 1, the figure expands, while a scale factor between 0 and 1 results in a reduction. Dilation is commonly used in geometry to study similarity between shapes, where corresponding angles remain equal, and corresponding sides are proportional. It plays a crucial role in various mathematical concepts and applications, such as transformations, similarity, and geometric modeling.
In a dilation, the points move closer or farther away from a certain point, called the center of dilation, by a certain factor. In this case, the dilation factor is given as 3, so the original point is gained by dividing the coordinates of the image by the dilation factor. The image of point A is given as (6,15). To find the original point A, we divide both coordinates by the dilation factor.
Divide the x-coordinate by the dilation factor: 6/3 = 2.Divide the y-coordinate by the dilation factor: 15/3 = 5.So, the original location of point A is (2,5).

In a function, each x-value has ________ y-value.
Explanation:
In a function, each x-value has one y-value.
___
That is the definition of a relation that is a function.
Final answer:
Each x-value in a function has exactly one corresponding y-value. Functions map elements of the domain to unique elements in the range, which can be represented graphically and must pass the vertical line test. The derivative in calculus, such as dy/dx, reflects the rate of change between these variables.
Explanation:
In a function, each x-value has one corresponding y-value. This is a foundational concept in mathematics that defines a relationship whereby each input (or x-value) in the function produces exactly one output (or y-value). Essentially, a function maps each element of the domain to exactly one element in the range.
An example of a function is y = f(x), which could represent a linear function like y = 3x + 2. In this case, for every x-value, there is a specific y-value determined by the function's formula. So if x were 1, then y = 3(1) + 2 = 5. The graphical representation of a function, such as its curve or line on a coordinate plane, must pass the vertical line test. That means if you draw a vertical line through any point on the graph, it should intersect the graph at no more than one point, confirming that each x-value has only one y-value.
Understanding functions is pivotal in different areas of mathematics, including calculus where the derivative of a function represents the rate of change of the y-value with respect to the x-value. In the case of the linear function y = 6+3x, the derivative dy/dx is constant at 3, implying that for every unit increase in x, y will increase by 3 units.

Write an exponential function for graph that passes through the following points (-3,80);(-1,20)
Final answer:
To find the exponential function that passes through (-3, 80) and (-1, 20), we use the general form y = abˣ. By solving a system of equations using these points, we find that the exponential function is y = 40*2ˣ.
Explanation:
To write an exponential function that passes through the points (-3, 80) and (-1, 20), we can use the general form of an exponential function, which is y = abˣ. Here, a and b are constants we need to find. Given two points, we can set up a system of equations to solve for a and b.
Using the first point (-3, 80):
80 = a*b⁻³
Using the second point (-1, 20):
20 = a*b⁻¹
Dividing the second equation by the first gives us:
b2 = 4 which simplifies to b = 2 or b = -2. However, in exponential functions, b is positive, so we choose b = 2.
Substituting b = 2 into the second equation gives a = 40. Thus, the exponential function is y = 40*2ˣ.

tabia stores her hair bands in a cube shaped container. the cube has a volume of 64 cubic inches. What is the lenght of the edges of the cube?
Answer:
The length of the edge of the cube = 4 inches
Step-by-step explanation:
* Lets describe the cube
- It has 6 faces all of them are squares
- It has 8 vertices
- It has 12 equal edges
∵ The volume of any formal solid = area of the base × height
∵ The base of the cube is a square
∴ Area base = L × L = L² ⇒ L is the length of the edge of it
∵ All edges are equal in length
∴ Its height = L
∴ The volume of the cube = L² × L = L³
* Now we have the volume and we want to find the
length of the edges
∵ Its volume = 64 inches³
∴ 64 = L³
* Take cube root to the both sides
∴ ∛64 = ∛(L³)
∴ L = 4 inches
* The length of the edge of the cube = 4 inches
The length of the edges of the cube is 4 inches.
Given that the volume V is 64 cubic inches, we can set up the equation:
[tex]\[ a^3 = 64 \][/tex]
To solve for a , we take the cube root of both sides:
[tex]\[ a = \sqrt[3]{64} \][/tex]
The cube root of 64 is 4, since [tex]\( 4^3 = 4 \times 4 \times 4 = 64 \).[/tex]
Therefore, the length of the edges of the cube is 4 inches.

Part B: A (-6 , -11) , B (-5 , -6) , C (-7 , -1) , D (0 , -8)
Step-by-step explanation:
* Lets study the reflection about the two axes X and Y
- The distance between the point and the axes of reflection =
the distance between its image and the axes
- The point and the its image are on opposite sides of the axes
- If a point (x , y) reflected about x axis, that means the point
will move vertically
- Moving vertically means we will change the sign of the y-coordinates
∴ The image of (x , y) after reflection about x-axis is (x , -y)
- If a point (x , y) reflected about y axis, that means the point
will move horizontally
- Moving horizontally means we will change the sign of the x-coordinates
∴ The image of (x , y) after reflection about x-axis is (-x , y)
* Now lets use the explanation above to solve our problem
- At first lets right the original point of the quadrilateral ABCD
∵ A (-6 , 11) , B (-5 , 6) , C (-7 , 1) , D (0 , 8)
Part A: The y-axis is the line of reflection
- Lets change the signs of x-coordinates in all points
∴ The new points after reflection about y-axis is:
A (6 , 11) , B (5 , 6) , C (7 , 1) , D (0 , 8)
- Note: The point D does not change because x-coordinate is 0
and there is no sign for the 0
Part B: The x-axis is the line of reflection
- Lets change the signs of y-coordinates in all points
∴ The new points after reflection about x-axis is:
A (-6 , -11) , B (-5 , -6) , C (-7 , -1) , D (0 , -8)
