Step-by-step explanation:
1. 5^2*5^6
=5^(2+6)
=5^8
2. e^2*e^7
= e^(2+7)
= e^9
3. 2a^5*6a
= 12a^6
4. 4x^2*(-5x^6
= -20x^8
Answer:
450 bacteria.
Step-by-step explanation:
To find this, we can set up an exponential equation as shown:
**'a' being the initial value
** '2' representing the culture doubling
Simplify the equation down:
Therefore, the initial amount of bacteria was 450.
Answer:
250
Step-by-step explanation:
c=10(250)=250
Answer:
yes
Step-by-step explanation:
A = P(1 + r)^t
A = total amount
P = principal
r = interest rate, as a decimal
t = time, in years
A = 5000·[(1 + .012)^8]
A = 5000(1.1001)
A = 5,500.65
amount of investment after 8 years = $5,500.65
two years of community college = $5,400
