Answer:
dV/dt = 13,5 [Km³/h]
Step-by-step explanation:
The volume f the cube is:
V = x³ where x is a side of the cube, then tacking derivatives with respect to time on both sides of the equation
dV/dt = 3*x² dx/dt
dx/dt = 2 km/h
at the time when the side x = 1,5 Km
dV/dt = 3* (1,5)²*2 [km³/h]
dV/dt = 13,5 [Km³/h]
The formula

means that from statement q implies statement p.
When statements p="two linear functions have different coefficients of x" and q="the graphs of two functions intersect at exactly one point", then the statement

have a form: "If the graphs of two functions intersect at exactly one point, then two linear functions have different coefficients of x."
Answer:
-2948
Step-by-step explanation:
Two signs (addition and subtraction) together makes subtraction when having a positive sign and a negative sign
Then subtract -38 and 2910
