The function which is decreasing is C. <span>Air pressure in the earths atmosphere as a function of altitude.
The higher you go, the less air pressure there is because of the fewer air molecules at such altitudes.
This means that the remaining functions are either constant or increasing. </span>
It would swim 30*15 metres, which is 450 metres.
Lol, I remember I helped my sister with this question but anyways, the card flew because of inertia and the quarter fell in the glass because of gravity :).
Answer:
y = -3x + 1
Explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 3x from both sides of the equation:
3x + y = 1
3x (-3x) + y = 1 (-3x)
y = -3x + 1
y = -3x + 1 is your answer.

Answer:
(a) 17450.8 J (B) 1.239 sec
Explanation:
We have given power output =8 KW
Heat expelled = 10994 j
Efficiency =37% = 0.37
(A) We know that efficiency 
Heat input =17450.8 J
(B) Work done by the engine is = 17450.8-10994=6456.8 j
Power output is given by 8 KW =8000 W
So time for each cycle is
