Answer:
a) 
b) 
Step-by-step explanation:
Assuming the complete question : "A town has a population of 1000 people at time t = 0. In each of the following cases, write a formula for the population, P, of the town as a function of year t. (a) The population increases by 50 people a year. (b) The population increases by 5% a year."
Part a
For this case we can use a linear model in order to estimate the population size since we have a fixed increase each year. So our model would be given by:
Where 
on this case since represent the increase per year of the slope for the linear model. And the initial amount is 
, so then the model is:
Part b
For this case we have a rate of increase and when we have this the lineal model is not the most appropiate. So then we can use an exponential model given by:
Where represent the initial population and for this case b is the rate of increase 
since each year we have an increase of 5% and t is the time. So then the model is given by:
Answer:
Step-by-step explanation:
e) 3√2 (-3√6 -2 -6)
3√2 (-3√6 - 8)
-9√12 - 24√2
-9√(2^2 * 3) - 24√2
-18√3 - 24√2
or
6(-3√3 - 4√2)
f) -5√2 (3 + 2√2 - 6 - 1)
-5√2(-4 + 2√2)
20√2 - 20
or
20(√2 - 1)
Into an improper fraction. An improper fraction is a fraction where the denominator is smaller than the numerator.
Example: Mixed number: 1 2/3
Improper fraction: 5/3
Answer:
7 : 6 is the ratio
Step-by-step explanation:
14 apples were green and 12 apples were red, so divide both terms by 2.
14 ÷ 2 = 7
12 ÷ 2 = 6
Therefore:
14 : 12 = 7 : 6.
