Let l: r^rightarrow r^3 be a transformation defined by l[(u_1, u_2, u_3, u_4)^t] = (u_1 + u_2, u_3 + u_4, u_1 + u_3)^t. [7 p] (a) show that l is a linear transformation. [9 b] (b) find a basis for kernel of l, ker(l), and determine its dimension. [9 p] (c) find a basis for image of r^4, l(r^4), and determine its dimension.

answer: 177/8

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
