Answer:
t = 0
Step-by-step explanation:
x = 10 − t²
dx/dt = -2t
y = t³ − 12t
dy/dt = 3t² − 12
dy/dx = (3t² − 12) / (-2t)
dy/dx = (12 − 3t²) / (2t)
dy/dx is undefined when the denominator equals 0.
2t = 0
t = 0

Answer:
486kg
Step-by-step explanation:
density = mass / volume
2.7 = m / (100 x 60 x 30) **** Note the conversion to cm as the density is given in g/cm.
2.7 = m / 180000
m = 486000g
Now convert to mass in kg:
486000 g x 1 kg / 1000 g = 486kg
9514 1404 393
Answer:
15
Step-by-step explanation:
When the smaller number is a divisor of the larger one, it is their highest common factor.
HCF(15, 45) = 15
