An airship flies in a direction of 20 degrees North of West at 420 mph. It encounters a 25 mph wind that is heading 17 degrees East of South. Its ground speed of 405.4 mph can be calculated. Equation below is used to find the drift angle of the airship. A. StartFraction sine A Over 25 EndFraction = StartFraction sine 53 Over 405.4 EndFraction B. 4202 = 252 + 405.42 – 2(25)(405.4)cos(A) C. c2 = 4202 + 405.42 D. Inverse tangent of (StartFraction 420 Over 405.4 EndFraction). The value of the drift angle is

Under normal conditions, 1.5 feet of snow will melt into 2 inches of water. during a winter season high in the mountains, 301 feet of snow fell. how many inches of water will there be when the snow melts?

One positive number is 9 more than twice another. if their product is 95, find the numbers

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.
