Define r and s as scalars r 1.6 x 103 and s-14.2. and t, x, and y as vectors t1,2, 3, 4, 5],x [2, 4, 6, 8, 10], and y [3, 6, 9, 12, 15]. Then use these variables to calculate the following expressions using element-by-element calculations for the vectors (a) G = xt + 2-x)t (b) R = - 15

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
