11 Consider a noninterlaced raster monitor with a resolution of n by m (m scan lines and n pixels per scan line), a refresh rate of r frames
a horizontal retrace time of thoriz, and a vertical
retrace time of t ert. What is the fraction of the total refresh time
and a
per second,
per frame spent in retrace of the electron beam?

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?

Visually impaired individuals generally rely on the for navigation. thus, designers need to ensure that mouse-specific inputs, such as pointing, clicking, and hovering, can be done without a mouse.
