Heya!
Here is your answer:
6a²-15a-8a+20
= 3a(2a-5) -4(2a-5)
= (3a-4)(2a-5)
:)
As function is = 4x
so
4x=-x+5
5x=5
x=1
Answer:
8/3 as a mixed number would be written as 2 2/3.
Not sure question is complete, assumptions however
Answer and explanation:
Given the above, the function of the population of the ants can be modelled thus:
P(x)= 1600x
Where x is the number of weeks and assuming exponential growth 1600 is constant for each week
Assuming average number of ants in week 1,2,3 and 4 are given by 1545,1520,1620 and 1630 respectively, then we would round these numbers to the nearest tenth to get 1500, 1500, 1600 and 1600 respectively. In this case the function above wouldn't apply, as growth values vary for each week and would have to be added without using the function.
On one hand, the function above could be used as an estimate given that 1600 is the average growth of the ants per week hence a reasonable estimate of total ants in x weeks can be made using the function.
