Answer:
x=1.65
Step-by-step explanation:
First switch sides
4x-8=3.6-2-3
Then subtract 3.6 - 2 - 3
4x-8=-1.4
Add 8 to both sides
4x-8+8=-1.4+8
simplify
4x=6.6
Divide both sides by 4
4x/4 - 6.6/4
The simplify again
x=1.65
Answer:
It'll take approximately 34 years from today.
Step-by-step explanation:
in order to solve this problem we first need to find the rate of change, "k", to do that we will use the given information where the population was 1400 five years ago and its now 1000. Applying this data to the equation gives us:
We now know the value for "k", we can estimate how many years it will take for the bird population to dip below 100. We have:
It'll take approximately 34 years from today.
Answer:
no
Step-by-step explanation:
If x = 3 is a zero, then f(3) = 0
f(3)
= 4 - 3³ - 52(3)² - 35(3) + 12
= 324 - 27 - 468 - 105 + 12
= - 264
Since f(3) ≠ 0 then x = 3 is not a zero of f(x)
