Answer:
This is an exponential growth equation of the form:
f(t) = A*(r)^t
Where:
A is the initial quantity of something, suppose that is the population of some kind of animal
r is the rate of growth
t is the variable, usually represents a unit of time.
f(t) is the population of the animal at the time t.
For this question, we have the equation:
b(t) = 1200*(1.8)^t
And this represents the population of a kind of bacteria as a function of time.
a) 1200 is the initial population of the bacteria.
b) the 1.8 is the rate of growth.
c) Now we have the equation:
b(t) = 1000*(1.8)^t
In this case, 1000 will represent the initial population of bacteria for this second study.
And the difference between the 1200 for the first study, and the 1000 for this second study, means that for the first study the initial population of bacteria was larger. (200 units larger).
Answer:
106.25 mph
Step-by-step explanation:
since the car travels at 85 miles per hour we divide it by 60 seconds in order to find how many miles is it to get in a minute
=> 85mph ÷ 60
divide 85 by 60
=> 1.416
multiply 1.416 by 15 to get how many miles it to go in 15 minutes
=> 21.25
then add it to 85
=> 106.25
To find the lowest common denominator you need to know the factors of 5 and 11.
So make two lists:
5, 10, 15, 20, 25, 30, and so on.
11, 22, 33, 44, 55, 66, and so on.
Keep doing that until you find the lowest common number in the lists. The LCD will be 55.
