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 .

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

you divide them and then you get the answer i took this class this year
