Let t: r3 → r3 be a linear transformation. use the given information to find the nullity of t nullity(t) = give a geometric description of the kernel and range of t. o the kernel of t is the yz-plane in r3, and the range of t is a line (the x- t is the projection onto the xy-coordinate plane: t(x, y, , y, 0) axis) o a. the kernel of t is a line (the x-axis), and the range of t is the yz-plane in r3 b. the kernel of t is the xz-plane in r3, and the range of t is a line (the y- axis)c. the kernel of t is the xy-plane in r3, and the range of t is a line (the z - axis)d. the kernel of t is a line (the z-axis), and the range of t is the xy-plane in axis) axis)

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
