The edges of a cube increase at a rate of 2 cm divided by s. How fast is the volume changing when the length of each edge is 40
Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

Let the edge of the cube be a .

Given

\frac{da}{dt} = 2 cm/s

Volume V = a³

\frac{dV}{dt} = 3a^ 2\frac{da}{dt}

= 3a² x 2

= 6a²

If a = 40 cm

\frac{dV}{dt} = 6 \times 40\times40

= 9600 cm³/s .

Square root of 3x^4 times square root of 5x^2 times square root of 10.
Cloud [144]

Answer:

Step-by-step explanation:

As long as the indices are the same for all the radicals, you can multiply them together. Our index for each of these is 2 (square root) so we multiply them all together and put it under 1 square root sign (radical):

\sqrt{150x^6  The largest perfect square in 150 is 25, and the 6th power on the x needs just to be rewritten in terms of an exponent of 2 to give us:

\sqrt{25*6*(x^3)^2} and pull out the perfect squares to get

5x^3\sqrt{6}
