For proper growth of the crystal, the temperature must be controlled accurately by adjusting the input power. Suppese the relationship is given by T(w) 0.1w+2.156w 20 where T is the temperature in degrees Celsius and w is the power input in watts (a) How much power is needed to maintain the temperature at 1989C? (Round your answer to two dedimal places.) watts (b) If the temperature is allowed to vary from 1O8C by up to 1°C, what range of wattage is allowed for the input power? (Round your answers to two decimal places.) watts watts
