Consider the vector space v = r[w] introduced in section 1.5 of the textbook, and define a function d: v v, df = f'. (that is, d is differentiation with respect to x.) (a) find all vectors v such that dv = 1 + 2x. (b) show that d is a linear transformation. (c) compute the kernel of d.

27 inches

Step-by-step explanation:

To find the length of the diagonal, we just need to use the cosine relation of the 48° angle.

The adjacent side to the angle is the height of the canvas, and the hypotenuse formed is the diagonal of the canvas. So, we have that:

cos(48) = height / diagonal

0.6691 = 18 / diagonal

diagonal = 18 / 0.6691 = 26.9 inches

Rounding to the nearest inch, the diagonal of the canvas measures 27 inches
