Find the index of refraction for rutile (a type of mineral) if a beam of light strikes the surface of this medium at an angle of 30° and produces an angle of refraction B = 18.7°. Use this index to find the angle of incidence if a second beam of light created an angle of refraction measuring 10°. -5 %3D 99. Roller coaster design: As part of a science fair gth)cos 0 COS project, Hadra builds a scale Loading platform model of a roller coaster using the equation 1 y = 5 sin-x + 7, where y is the height of the %3D model in inches and x is the distance from the "loading platform" in inches. (a) How high is the platform? (b) What distances from the platform does the model attain a height of 9.5 in.? 100. Company logo: Part of the logo for an engineering firm was modeled by a cosine function. The logo was then manufactured in steel and installed on the entrance marauee of the home office.
