Answer:
a) Q(t) = 89 + 12t
b) Q(3) = 125 millions of bacteria
Step-by-step explanation:
a)
to write a function of the growth of bacteria, we need to consider the initial population and add it to the new bacteria. Also we need to consider that the result of the function is in millions of bacteria, so when we get a result, we express it in millions.
Data
Initial population = 89 just add it to the function given 12t
Q(t) = 89 + 12t
b) Data time = 3 h
Q(3) = 89 + 12(3) substitution
Q(3) = 89 + 36 simplifying
Q(3) = 125 millions of bacteria
Answer:
2.39%
Step-by-step explanation:
Maxwell bought $15,000 worth of 52-week T-bills for $14,650
Therefore the rate of return on investment can be calculated as follows
= 15,000-14,650/14,650× 100
= 350/14,650 × 100
= 0.02389 × 100
= 2.39%
Hence the rate of return on this investment is 2.39%
Answer:
ΔT = -75°F
Step-by-step explanation:
ΔT = T₁ - T₀ = 350 - 425 = -75°F
Answer: 225
Step-by-step explanation:
Circle is 360°
Here, each part is 45°
C to H is five parts,
5 * 45 = 225
