Answer to Problem 7.9.5P
Therelationship between number of sides and the sum of interior angles are not in geometric sequence
Explanation of Solution
Given information:
Sum of interior angle of a
Sum of interior angle of a pentagon is 540°
Sum of interior angles of a square is,
On solving,
Triangle has 3 sides and sum of interior angle is 180°
Squarehas 4 sides and sum of interior angle is 360°
Pentagonhas 5 sides and sum of interior angle is 540°
The common ratio between the numbers is not same. Hence, the relationship between number of sides and the sum of interior angles are not in geometric sequence. Rather, the relationship is in an arithmetic sequence, because the common difference is same.

- 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 .
