018 10.0 points A fireman standing on a 14 m high ladder
operates a water hose with a round nozzle of
diameter 2.13 inch. The lower end of the hose
(14 m below the nozzle) is connected to the
pump outlet of diameter 3.15 inch. The gauge
pressure of the water at the pump is
(abs)
= 57.3 PSI = 395.07 kPa.
Calculate the speed of the water jet emerg-
ing from the nozzle. Assume that water is an
incompressible liquid of density 1000 kg/m
3
and negligible viscosity. The acceleration of
gravity is 9.8 m/s2
Answer in units of m/s

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =

Hich equation can pair with x + 2y = 5 to create an inconsistent system? 2x + 4y = 3 5x + 2y = 3 6x + 12y = 30 3x + 4y = 8
