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 .

Given f(x) = x − 7 and g(x) = x2 . Find g(f(−1)).
ivann1987 [24]

Answer:

64

Step-by-step explanation:

g(f(-1)) can be found by first finding f(-1) then taking that result and putting it into the function g.

f(-1) means we are going to take the expression x-7 and evaluate it for x=-1:  

-1-7

-8

So f(-1)=-8.

So we have this so far:

g(f(-1))=g(-8)=(-8)^2=64.

g(-8) was found by replacing x in x^2 with -8.
