The answer is 42.3
Step by Step:
Let our variable be n, standing for number.
3.6(x) + 4.5(y) = n
3.6(3) + 4.5(7) = n
10.8 + 31.5 = n
n = 42.3
The second one because it passes through the origin
Answer:
No, only sometimes.
Step-by-step explanation:
Only a regular polygon has interior angles that are all congruent.
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]
