Answer:
The rate of exponential growth of a bacterial culture is expressed as generation time, also the doubling time of the bacterial population. Generation time (G) is defined as the time (t) per generation (n = number of generations). Hence, G=t/n is the equation from which calculations of generation time (below) derive
Step-by-step explanation:
Answer:
64
Step-by-step explanation:
64 is both a perfect square and a perfect cube.
8*8=64
4*4*4=64
Answer:
V = x³ - 3x² + 3x - 1
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( s is the measure of the side )
Here s = x - 1 , thus
V = (x - 1)³
= (x - 1)(x - 1)(x - 1) ← expand the second pair using FOIL
= (x - 1)(x² - 2x + 1) ← distribute
= x³ - 2x² + x - x² + 2x - 1 ← collect like terms
= x³ - 3x² + 3x - 1
Answer:
17.32
Step-by-step explanation:
to get TU
sinФ = opposite/hypothenus
sin 60° = TU/20
√3/2=TU/20
( √3/2 ) x 20 = 10√3 = TU = 17.3205080757 = 17.32
