Five million bacteria live in an organism. The doubling period is 1.5 hours. How many will there be after:
finlep [7]
We write the generic exponential equation:
 y = A (b) ^ t
 Where,
 A: initial population
 B: growth rate
 t: time in hours.
 Substituting values we have:
 y = 5 (2) ^ ((1 / 1.5) * t)
 For t = 9 hours we have:
 y = 5 (2) ^ ((1 / 1.5) * 9)
 y = 320 million
 For t = 24 hours (one day) we have:
 y = 5 (2) ^ ((1 / 1.5) * 24)
 y = 327680 million
 For t = 2 hours we have:
 y = 5 (2) ^ ((1 / 1.5) * 2)
 y = 12.5992105 million
 Answer:
 
a) t hours?
 
y = 5 (2) ^ ((1 / 1.5) * t)
 
b) 9 hours?
 
y = 320 million
 
c) 1 day?
 
y = 327680 million
 
d) 2 hours?
 
y = 12.5992105 million

1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15
Inessa [10]

Answer:

\frac{4+16a^3+23a^3}{a^2}

Step-by-step explanation:

Given

1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15

Required

Simplify

1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15

Collect Like Terms

1/a^2 + 1/a^2 + 2/a^2-3a-5a-8a+2+6+15

1/a^2 + 1/a^2 + 2/a^2-16a+23

Add Fractions:

\frac{1+1+2}{a^2} + 16a + 23

\frac{4}{a^2} + 16a + 23

This can be further expressed as:

\frac{4+16a^3+23a^3}{a^2}
