15 x 24 --> área = 15*24 = 360 ft²
1 ft² = 17,00
360 ft² = ...
Price = 360*17
Price = US$ 6.120,00
The coordinates of a particle of water "t" seconds after it leaves the end of the fire hose will be
.. (x, y) = (38.4*cos(47.5°)t, -4.9t^2 +38.4*sin(47.5°)t)
Solving for t, we have
.. t = x/(38.4*cos(47.5°)
For x = 25.7 meters, t is about 0.99065 seconds.
Then y will be
.. -4.9*(0.99065)^2 +38.4*sin(47.5°)*0.99065 = 23.238 . . . . meters
The water will hit the building about 23.24 meters above the height of the hose.
Answer:
(X-8) and (x+1)
Step-by-step explanation:
If we multibly then (X-8) (x+1)=0 =x^2-7x-8=0
The answer is indeed 40 K.
Use order of operations to simplify the expression.
