b.
To evaluate what does y intercept indicate
b.

Answer to Problem 4.1.5P
The y-intercept indicate the total money She owes.
Explanation of Solution
Given information:
The data of how much S owed in a given week
The y- intersect is that point where the line intersects the y-axis. In this situation, the y- intercept represents the total money she owes to her brother.
c.
To evaluate what does slope indicate
c.

Answer to Problem 4.1.5P
The slope shows the rate of change of money she owes.
Explanation of Solution
Given information:
The data of how much S owed in a given week
The slope shows the rate of change in y. In this situation, slope shows the change in how much S owes in brother.
d.
To evaluate what does x- intercept represent.
d.

Answer to Problem 4.1.5P
The x- intercept shows the number of week it took to return the money.
Explanation of Solution
Given information:
The data of how much S owed in a given week
The x- intercept is the point where the line meets the x- axis. In this situation, x- intercept shows the total number of week it took S to return all the money she owed to her brother.
e.
To evaluate what does that straight line graph indicate.
e.

Answer to Problem 4.1.5P
The straight line graph indicate that the return of money is constant.
Explanation of Solution
Given information:
The data of how much S owed in a given week
The straight line tells that S is returning the money she owes to her brother on time. The return of money is continuous and there is no week she isn’t paying back the money. Hence, the return of money is constant.

- You are given a plane Π in R3 defined by two vectors, p1 and p2, and a subspace W in R3 spanned by twovectors, w1 and w2. Your task is to project the plane Π onto the subspace W.First, answer the question of what the projection matrix is that projects onto the subspace W and how toapply it to find the desired projection. Second, approach the task in a different way by using the Gram-Schmidtmethod to find an orthonormal basis for subspace W, before then using the resulting basis vectors for theprojection. Last, compare the results obtained from both methodsarrow_forwardPlane II is spanned by the vectors: - (2) · P² - (4) P1=2 P21 3 Subspace W is spanned by the vectors: 2 W1 - (9) · 1 W2 1 = (³)arrow_forwardshow that v3 = (−√3, −3, 3)⊤ is an eigenvector of M3 .
