True It forms a 30, 60, 90 triangle and 3, 4, and 5 are what we call a Pythagorean Triple, If you don't know what that is, ask your teacher, I'm sure they will either get to it later or will tell you right then and there! :)
Step-by-step explanation:
For each cell in the difference column, simply subtract the second blue column from the first.
$525 - $500 = $25
$0 - $80 = -$80
$100 - $65 = $35
At the bottom, the surplus/shortage is the total wages - total expenses.
$2500 - $2597 = -$97
$2650 - $2502 = $148
The vertex of the graph of the function g(x) = (x - 2)^2 + 3 is 2 units to the right and 3 units up of the vertex of the graph of the function f(x) = x^2.
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.
