A pair of smart sunglasses is designed so that the percentage p of light allowed through the sunglasses is given by p = 50 + 50e-0.0005x , where x is brightness of the exterior light (in ft-c). (a) Find the percent of light allowed through the sunglasses on a cloudy day (100 ft-c). (b) Find the percent of light allowed through the sunglasses on a bright sunny day (11,000 ft-c). (c) Display the graph on a calculator. (a) On a cloudy day (100 ft-c). % of light is allowed through the sunglasses. (Round to the nearest whole number as needed.) (b) On a bright sunny day (11,000 ft-c), % of light is allowed through the sunglasses. (Round to the nearest whole number as needed.) (c) Choose the correct graph below. O A. O B. O C. O D. AP AP AP AP 100- 100- 100- X X 12,000 12,000 -12,000 -12,000A driver using a mapping app finds that it is 400 mi to her destination. If her speed always stays between 40 mi/h and 50 mi/h, inclusively, use an inequality to express the required time t for the trip. Write a single inequality to express the required time t for the trip. (Type an inquality using t as the variable. Type your answer using the appropriate number of significant digits.)
