The equation for the discounted price should be:
A' = $25*(1 - 20%/100%) = $20
How to find the discounted price?If we have an initial value A, and we decrease it by X (a percentage) then:
The discounted amount is:
D = A*(X/100%)
The new value is:
A' = A*(1 - X/100%)
So, if the initial value is $25 and there is a discount of the 20%, the new value of the item will be:
A' = $25*(1 - 20%/100%)
A' = $25*(1 -0.2)
A' = $25*0.8 = $20
That is the correctly discounted price.

Can you help me wit #3 part a,b,c
Answers
Answer:
3a. The polygon has 15 sides, so it is a pentadecagon or a 15-gon.
3b. Each interior angle measures 156°.
3c. The measure of an exterior angles is 24°
Step-by-step explanation:
3a
(n - 2)180 = 2340
n - 2 = 13
n = 15
The polygon has 15 sides, so it is a pentadecagon or a 15-gon.
3b
2340/15 = 156
Each interior angle measures 156°.
3c
There are 2 ways to calculate the measure of an exterior angle.
Method 1:
Each exterior angle is supplementary to its adjacent interior angle.
156 + x = 180
x = 24
Method 2:
The sum of the measures of the exterior angles of a polygon, 1 per vertex, is 360, no matter the number of sides.
360°/15 = 24°
The measure of an exterior angles is 24°

find the first partial derivatives and evaluate each at the given point. function point w = 3x2y − 7xyz 10yz2 (4, 3, −2)
Answers
The partial derivatives of the given function at the point (4, 3, -2) is equal to wₓ(4, 3, -2) = 114 , \(w_{y}\)(4, 3, -2) = -16 , and\(w_{z}\)(4, 3, -2) = 96.
Function w= 3x²y − 7xyz + 10yz²
and Point (4, 3, −2)
To find the partial derivatives of the function w = 3x²y - 7xyz + 10yz² with respect to x, y, and z,
Differentiate each term of the function separately and evaluate them at the given point (4, 3, -2).
Partial derivative with respect to x (wₓ).
To find wₓ,
differentiate each term with respect to x while treating y and z as constants.
wₓ = d(3x²y)/dx - d(7xyz)/dx + d(10yz²)/dx
Differentiating each term,
wₓ = 6xy - 7(yz) - 0 since there is no x term in the last term.
Now, substitute the given point (4, 3, -2) into the expression for wₓ.
wₓ(4, 3, -2)
= 6(4)(3) - 7(3)(-2)
= 72 + 42
= 114
Partial derivative with respect to y (\(w_{y}\)).
To find \(w_{y}\),
differentiate each term with respect to y while treating x and z as constants.
\(w_{y}\)= d(3x²y)/dy - d(7xyz)/dy + d(10yz²)/dy
Differentiating each term.
\(w_{y}\) = 3x² - 7xz + 20yz
Substitute the given point (4, 3, -2) into the expression for \(w_{y}\)
\(w_{y}\)(4, 3, -2)
= 3(4)² - 7(4)(-2) + 20(3)(-2)
= 48 + 56 - 120
= -16
Partial derivative with respect to z ( \(w_{z}\))
To find \(w_{z}\), we differentiate each term with respect to z while treating x and y as constants:
\(w_{z}\) = d(3x²y)/dz - d(7xyz)/dz + d(10yz²)/dz
Differentiating each term.
since there is no z term in the first term
\(w_{z}\) = 0 - 7xy + 20y²
Substitute the given point (4, 3, -2) into the expression for \(w_{z}\)
\(w_{z}\)(4, 3, -2)
= -7(4)(3) + 20(3)²
= -84 + 180
= 96
Therefore, the partial derivatives of the function w = 3x²y - 7xyz + 10yz² at the point (4, 3, -2) are,
wₓ(4, 3, -2) = 114
\(w_{y}\)(4, 3, -2) = -16
\(w_{z}\)(4, 3, -2) = 96

Answers
The first statement is about the dimension of the span of the three vectors, the second statement is about the span being equal to \(\mathbb{R}^3\), and the third statement is the same as the second but includes the condition that \(v_1\), \(v_2\), and \(v_3\) are linearly independent.
Let's go through each question one by one:
1. Given the matrix \(A\), we are told that it is non-invertible. To find the value of the constant \(k\), we can examine the determinant of \(A\). If the determinant is zero, then \(A\) is non-invertible. Therefore, we need to calculate the determinant of \(A\) and set it equal to zero to find \(k\).
2. The coordinates of \(y=(3,5)\) with respect to the ordered basis \(B=\{u_1,u_2\}\) can be found by expressing \(y\) as a linear combination of \(u_1\) and \(u_2\). We need to find scalars \(c_1\) and \(c_2\) such that \(y = c_1u_1 + c_2u_2\).
3. We are given two matrices, \(M\) and \(N\), and told that \(A = M^TN\). To find \(\text{det}(A)\), we can use the property that the determinant of a product of matrices is equal to the product of the determinants of the individual matrices. Therefore, we need to calculate \(\text{det}(A)\) using the given matrices \(M\) and \(N\).
4. In this question, we have vectors \(v_1\), \(v_2\), and \(v_3\) in \(\mathbb{R}^3\). We need to determine which of the given statements are true. The first statement is about the dimension of the span of the three vectors, the second statement is about the span being equal to \(\mathbb{R}^3\), and the third statement is the same as the second but includes the condition that \(v_1\), \(v_2\), and \(v_3\) are linearly independent.

Thanks again!!
Answers
Step-by-step explanation:
First, a half plane can be defined as one side of a line, e.g. x < y-3.
1: True. A solution to two half planes is where the two half planes intersect. If they never intersect, then there literally cannot be a solution.
2: False. Take, for example, y=x and y=x+1. These two lines are parallel because in the equation y=mx+b, m represents the slope, and in these two lines, x is multiplied by 1, so both lines have the same slope and are therefore parallel. Then, take two boundary planes -- y > x and y>x+1. If we graph this out (see picture), the planes clearly intersect when y>x+1. The solution is where the planes intersect, so there is a solution area

Background knowledge about the sequence function
A sequence is defined as the function whose domain is the set of natural numbers (counting numbers).
1, 2, 3, 4, .... n, ....
↓
a₁, a₂, a₃, a₄, .... aₙ, ....
Here,
1 gets mapped onto a₁,
2 gets mapped onto a₂, and so on
The numbers a₁, a₂, a₃, a₄, .... aₙ, .... are the terms of the sequence.
The number aₙ is the nth term of a sequence.
And the sequence function is denoted by {aₙ}.
Given the sequence
3, 9, 15, 21, ...
Here,
a₁ = 3 is the first term
a₂ = 9 is the second term
Thus, the ordered pair to represent the second term as an ordered pair is:

What is the solution of the inequality shown
below?
y+7≤-1
Answers
The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.
To solve the inequality y + 7 ≤ -1, we need to isolate the variable y on one side of the inequality sign.
Starting with the given inequality:
y + 7 ≤ -1
We can begin by subtracting 7 from both sides of the inequality:
y + 7 - 7 ≤ -1 - 7
y ≤ -8
The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.
In the context of a number line, all values to the left of -8, including -8 itself, will make the inequality true. For example, -10, -9, -8, -8.5, and any other value less than -8 will satisfy the inequality. However, any value greater than -8 will not satisfy the inequality.

Answers
The terms "vertex," "origin," and "factor" are relevant in various math contexts. I assume you have a coordinate plane with two given points: (24, 4) and (6, 4). Let's use these terms to analyze the situation:
1. Vertex: A vertex is a corner point where two or more lines meet. In this case, the given points could be vertices of a shape, such as a rectangle or triangle.
2. Origin: The origin is the point (0, 0) on a coordinate plane, where the x-axis and y-axis intersect. Both given points are located to the right of the origin and above it.
3. Factor: A factor is a number that divides another number evenly. In this context, we can find factors of the x-coordinates. For example, factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. Factors of 6 are 1, 2, 3, and 6.
