Which of these is a unit of density?
Naddika [18.5K]
<h3><u>Answer:- </u></h3>

\longrightarrow \textsf{The unit of density is\;}\sf kg/m^3

<h3><u>Solution</u> :-</h3>

\green{ \underline { \boxed{ \sf{Density =  \frac{Mass}{Volume}}}}}

\longrightarrowThe unit of mass is kg and unit of Volume is m³ . Since density is division of mass by volume , the corresponding units will also get divided and unit of density would come out to be kg/m³

<u>Some basic </u><u>derived </u><u>Units :- </u>

  • area => m²
  • volume cubic meter => m3
  • speed meter per second => m/s
  • acceleration => m/s²
  • mass density meter => kg/m3
  • specific volume cubic meter per kilogram m³/kg

Which functions have graphs that are steeper than the graph of f(x)=−3x^2?
netineya [11]

Answer:

g(x)=−4x^2  and m(x)=4x^2

Step-by-step explanation:

A horizontal stretch or shrink happens when you multiply the parent function (in this case f(x) = x²) by a number.  If this number is between 0 and 1, the graph will be stretched horizontally.  If this number is greater than 1, the graph will be shrunk horizontally.  If the number is between -1 and 0, the graph will be stretched horizontally and flipped; if the number is less than -1, the graph will be shrunk horizontally and flipped.

The graphs that are horizontally shrunk are steeper than the others.  This is m(x)=4x^2  and g(x) = -4x^2.
