Recall from class that m is the vector space of all 2 x 2 matrices with real entries. let w be the set of all symmetric 2 x 2 matrices. (a) (5 points) show that w is a subspace of m2x2. (hint: the way lay does this, there are three things to check.) (b) (4 points) write down a basis for w. (hint: symmetric matrices look like c) (6 points) using the definition of basis, show that your basis really is a basis. (d) (1 point) fill in the blank with the correct number: the dimension of w is .

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
