A forest ranger is watching the progress of a forest fire spreading towards her from the top of a 3050-foot mesa. In 4 minutes, the angle of depression to the leading edge of the fire changes from 11.82" to 12.17". How many feet does the fire advance during the 4 minutes that the ranger is observing it? (Round your answer to two decimal places) feet At what speed (in MILES PER HOUR) is the fire spreading towards the ranger? (Round your answer to two decimal places.) miles per hour blam

Q5: As a hot-air balloon began to rise, the ground crew drove 1.2 miles to an observation station. The initial observation from the station estimated the angle between the ground and the line of sight to the balloon to be 30°. Calculate distance "h" and "x" given in the diagram below. h 1.2 mi 30%

Evaluate 7000(0.05)".S for t= 3 and for t= 5. 7000(0.05)°S 0.5 22 when t= 3 (Do not round until the final answer. Then round to two decimal places as needed.)

B 1. Refer to the circle on the right, AR if MBDN = 164 and mRN = 78, find m/RAN, if mBR = 100 and mRN = 86, find m/A. N
