<em>This will result in </em><em>120</em>
Answer:
6 kg/m
Step-by-step explanation:
mass m = 3x^2.
rho ρ= dm/dx =6x
ρ(1) =6 Kg/m
linear density is the derivative of mass (m) with respect to position(x)
that is how fast is the mass changing at that position.
Answer:
5/√3 inches long.
Step-by-step explanation:
The property is that the lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3. Thus if you know that the side opposite the 60 degree angle measures 5 inches then then this is √3 times as long as the side opposite the 30 degree so the side opposite the 30 degree angle is 5/√3 inches long.
Answer:
x = 7
Step-by-step explanation:
7x - 12 = 9x - 26
7x - 12 = 9x - 26
+12 +12
7x = 9x - 14
7x = 9x - 14
-9x -9x
-2x = -14
-2x = -14
___. ___
-2 -2
x = 7
