Amanda is using wire to construct a triangle for an art project. She has 4 inches of blue eirr and 8 inches of green wire. Amanda is going to buy some purple wire for the third side of her triangle. She needs to buy enough wire to make a triangle, but does not want to have any wire let over. What is the least amount and the greatest amount of purple wire she could buy?
Amana could buy more than ___ inches but less than ___ inches of purple wire.
Amanda could buy more than 4 inches but less than 8 inches of purple wire to make triangle.
For Amanda to make a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Therefore, the minimum amount of purple wire she could buy would be the sum of the lengths of the blue and green wires (4 inches + 8 inches = 12 inches), minus the length of the longest side (which is 8 inches), so 12 inches - 8 inches = 4 inches.
The maximum amount of purple wire she could buy would be the sum of the lengths of the two shorter sides (4 inches + 4 inches = 8 inches).

The cost of downloading 10 songs for Johnny is $30.
The cost of downloading music for Johnny can be represented by the expression 1.5x + 15, where x is the number of songs downloaded. To find the cost of downloading 10 songs, we can plug in x = 10 into the expression:
1.5 * 10 + 15 = 15 + 15 = 30
So, it will cost Johnny $30 to download 10 songs. This expression represents the total cost as the sum of a $30 $30 ($15 monthly fee) and a variable cost ($1.50 per song fee).
The fixed cost remains constant regardless of the number of songs downloaded, while the variable cost increases as more songs are downloaded.

let u and a . is u in the plane in spanned by the columns of a why or why not
u in the plane is not spanned by the columns of A.
If u in the plane in spanned by the columns of A, then u can be obtained by the linear combination of the columns of A. That is
(4, -1, 4) = x(2, 0, 1) + y(5, 1, 2) + z(-1, -1, 0)
In matrix form we get

For the vectors u = (-4,-1) and v= (1,3), express u as the sum u=p+n, where p is parallel to v and n is orthogonal to v. + 7 21 33 11 u=p+n= 10 10 10 10
For the given vectors the sum of u is (-44/10,-6/10).
Vectors are mathematical objects that have both magnitude and direction.
The projection of u onto v is equal to the dot product of u and the unit vector of v divided by the magnitude of v.
The unit vector of v can be found by dividing v by its magnitude. Once we have the unit vector, we can multiply it by the dot product and add it to the initial point of v to find p.
Since u = (-4,-1) and v = (1,3), the magnitude of v is √(1^2 + 3^2) = √10 and the unit vector of v is (1/√10, 3/√10).
The dot product of u and the unit vector of v is
=> (-4)(1/√10) + (-1)(3/√10)
=> -4/√10 - 3/√10.
Thus,
=> p = (-4/√10 - 3/√10)(1/√10, 3/√10) + (1,3)
=> p = (-4/10 - 3/10, -1/10 + 3/10) + (1,3)
=> p = (7/10 + 3/10, 2/10 + 3/10) = (10/10, 5/10).
To find n vector, we subtract p from u.
Finally,
=> n = u - p = (-4,-1) - (10/10, 5/10)
=> (-4 - 10/10, -1 - 5/10) = (-44/10,-6/10).

What is linear transformation?A function from one vector space to another that respects the underlying (linear) structure of each vector space is called a linear transformation.
A linear operator, or map, is another name for a linear transformation.
The zero transformation and identity transformation are two significant illustrations of linear transformations.
An illustration of a linear transformation is the zero transformation, which is denoted by T(x)=(0) for every x.
Also linear is the identity transformation denoted by T(x)=(x).
Find the vector subspace in which the implicit equations are the homogeneous equations produced when the components of the linear transformation formula are equal to zero in order to compute the kernel.

Step-by-step explanation:
find the area of the region that is bounded above by the curve f(x)=(x 8)2 and the line g(x)=−x−2 and bounded below by the x-axis.
The area of the region bounded by f(x)=(x-8)^2, g(x)=-x-2 and the x-axis is the definite integral of f(x)-g(x) from -2 to 8.
The area of the region bounded by f(x)=(x-8)^2, g(x)=-x-2 and the x-axis is given by the definite integral of f(x)-g(x) from -2 to 8. First, expand f(x) and g(x) to get f(x)=x^2-16x+64 and g(x)=-x-2. Then, subtract g(x) from f(x) to get f(x)-g(x)=x^2-16x+66. This is the equation of the area of the region. To calculate the area, use the definite integral of f(x)-g(x) from -2 to 8. This is equivalent to the integral from -2 to 8 of x^2-16x+66 dx. After integrating, the area is given by the expression (x^3/3)-8x^2+66x from -2 to 8, which is equal to 1176/3 units^2. Therefore, the area of the region bounded by f(x), g(x) and the x-axis is 1176/3 units^2.

The sum of the angle measures of a polygon with s sides is
2 and 340( degrees). Find s.
The sum of the angle measures of a polygon with s sides can be calculated using the formula:
(s - 2) * 180 degrees
We can use this formula to solve for s:
2 = (s - 2) * 180
Dividing both sides by 180:
2 / 180 = (s - 2)
Solving for s:
s = 2 + 2 / 180 = 2 + 1 / 90 = 2 + 1 / 90 * 180 / 180 = 2 + 2 / 3
So the number of sides of the polygon is s = 2 + 2 / 3 = 4 2/3.
Since a polygon must have a whole number of sides, s cannot be a fraction, which means this answer is not a valid solution for the number of sides of a polygon. I don't think the problem as stated does not have a valid solution.

-Exploring Linear Equations in Two Variables
Answer:
4x + y = 15
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 4 , then
y = - 4x + c ← is the partial equation
to find c substitute (2, 7 ) into the partial equation
7 = - 4(2) + c = - 8 + c ( add 8 to both sides )
15 = c
y = - 4x + 15
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
then
y = - 4x + 15 ( add 4x to both sides )
4x + y = 15 ← in standard form
